  Treatment of primary hypothyroidism in adults […] In most patients, hypothyroidism is a permanent condition requiring lifelong treatment. Therapy consists of thyroid hormone replacement, unless the hypothyroidism is transient (as after painless thyroiditis or subacute thyroiditis) or reversible (due to a drug that can be discontinued). […] The goal of therapy is restoration of the euthyroid state, which can be readily accomplished in almost all patients by oral administration of synthetic thyroxine (T4, levothyroxine). Appropriate treatment should reverse all the clinical manifestations of hypothyroidism. […] This topic will review the major issues that must be addressed in the treatment of adults with overt primary hypothyroidism.

  Treatment for hypothyroidism usually includes taking the thyroid hormone medicine levothyroxine (Levo-T, Synthroid, others) every day. This medicine is taken by mouth. It returns hormone levels to a healthy range, eliminating symptoms of hypothyroidism. […] Levothyroxine typically causes no side effects when used in the correct dose. If you change brands of the medicine, tell your health care provider, as the dosage may need to change. […] If you are diagnosed with subclinical hypothyroidism, talk about treatment with your health care provider. For a mild rise in TSH, thyroid hormone medicine may not be useful. If your TSH level is higher, but still in the subclinical range, thyroid hormones may improve some symptoms. […] Most health care providers recommend taking the medicine levothyroxine to treat hypothyroidism. But an extract containing thyroid hormone derived from the thyroid glands of pigs is available. It is sometimes called desiccated thyroid extract. However, this treatment is not recommended because the amount of T-4 and T-3 in it may not be consistent from batch to batch. It is not safe for pregnant people to take desiccated thyroid extract because it can harm a fetus’s development.

  An underactive thyroid (hypothyroidism) is usually treated by taking daily hormone replacement tablets called levothyroxine. […] Levothyroxine replaces the thyroxine hormone, which your thyroid does not make enough of. […] You’ll initially have regular blood tests until the correct dose of levothyroxine is reached. This can take a little while to get right. […] You may start on a low dose of levothyroxine, which may be increased gradually, depending on how your body responds. Some people start to feel better soon after beginning treatment, while others do not notice an improvement in their symptoms for several months. […] Once you’re taking the correct dose, you’ll usually have a blood test once a year to monitor your hormone levels. […] If blood tests suggest you may have an underactive thyroid, but you do not have any symptoms or they’re very mild, you may not need any treatment. In these cases, the GP will usually monitor your hormone levels every few months and prescribe levothyroxine if you develop symptoms.

  Clinical hypothyroidism should be treated with levothyroxine to normalize the TSH level and relieve signs and symptoms. Evidence does not support the use of T3, alone or in combination with levothyroxine. Levothyroxine should be taken once per day, 30 to 60 minutes before eating, and four hours before or after drugs that may impede absorption. In patients who are not pregnant, TSH should be monitored every six to eight weeks until within normal range, then every six to 12 months, barring a change in clinical status. […] In older adults, hypothyroidism may have a subtle or more nonspecific presentation. Few older patients with confirmed hypothyroidism have overt symptoms to suggest disease. […] Pregnancy is associated with increased levothyroxine requirements as early as the fourth week of gestation. Once pregnancy is confirmed, patients with existing hypothyroidism should start taking an extra dose of levothyroxine two days per week for a total of nine doses per week. […] Patients on high dosages of levothyroxine (greater than 200 mcg per day) with persistently elevated TSH levels may be nonadherent or have absorption issues attributed to meal timing or other medications. Adding T3 to levothyroxine does not additionally alleviate symptoms of hypothyroidism.

  If you’re prescribed levothyroxine, you should take it at the same time every day. […] An underactive thyroid is a lifelong condition, so you’ll usually need to take levothyroxine for the rest of your life. […] If you’re prescribed levothyroxine because you have an underactive thyroid, you’re entitled to a medical exemption certificate. This means you do not have to pay for your prescriptions. […] Levothyroxine does not usually have any side effects, because the tablets simply replace a missing hormone. […] Side effects usually only occur if you’re taking too much levothyroxine. […] In the UK, combination therapy using levothyroxine and triiodothyronine (T3) together is not routinely used because there’s insufficient evidence to show it’s better than using levothyroxine alone (monotherapy).

  Tips for taking your levothyroxine—Levothyroxine should be taken once per day on an empty stomach (ideally one hour before eating or four hours after). Most people take their medication as soon as they wake in the morning and delay eating breakfast as long as practical before leaving for work or school. […] […] Foods with a lot of fiber, calcium- or aluminum-containing antacids, and iron tablets can interfere with the absorption of levothyroxine and should be taken at a different time of day. […] […] Generic (levothyroxine) and brand-name (for example, Synthroid, Levoxyl, Unithroid, Euthyrox) are available as tablets, and gel-caps and liquid preparations are also available (Tirosint, Thyquidity). These formulations are equally effective. […] […] It is preferable to stay on the same manufacturer of levothyroxine if possible, rather than switching between brand name and/or generic formulations. However, if you do need to switch to a different formulation of levothyroxine, the dose usually doesn’t need to change. If you don’t feel as well with the new formulation, your health care provider can do a blood test to check your thyroid hormone levels about six weeks after making the switch. This can help them determine whether your dose needs to be adjusted. […]

  The treatment goals for hypothyroidism are to reverse clinical progression and correct metabolic derangements, as evidenced by normal blood levels of thyroid-stimulating hormone (TSH) and free thyroxine (T4). Thyroid hormone is administered to supplement or replace endogenous production. In general, hypothyroidism can be adequately treated with a constant daily dose of levothyroxine (LT4). […] Thyroid hormone can be started at anticipated full replacement doses in individuals who are young and otherwise healthy (1.6 g/kg/day). Pregnant women will require doses about 25% higher. In elderly patients and those with known ischemic heart disease, treatment should begin with one fourth to one half the expected dosage, and the dosage should be adjusted in small increments after no less than 4-6 weeks. For most cases of mild to moderate hypothyroidism, a starting levothyroxine dosage of 50-75 g/day will suffice.

  Serum TSH monitoring is advisable when medications such as phenobarbital, phenytoin, carbamazepine, rifampin, and sertraline are started. […] When deciding on a starting dose of levothyroxine, the patients weight, lean body mass, pregnancy status, etiology of hypothyroidism, degree of TSH elevation, age, and general clinical context, including the presence of cardiac disease, should be considered; the serum TSH goal appropriate for the clinical situation should also be considered. […] Thyroid hormone therapy should be initiated as an initial full replacement or as partial replacement with gradual increments in the dose titrated upward using serum TSH as the goal. […] Dose adjustments should be made upon significant changes in body weight, with aging, and with pregnancy; TSH assessment should be performed 4-6 weeks after any dosage change.

  Hypothyroidism is the name given to the condition resulting from an underactive thyroid gland. This means that the thyroid is not producing enough thyroid hormone for the body’s needs. […] Your doctor will prescribe levothyroxine, a synthetic version of the thyroxine produced by the thyroid gland. Levothyroxine is very pure, and has negligible side-effects when taken in the correct dose. […] Levothyroxine doses are dependent upon the person’s body weight and their blood test results. Most patients require between 100 and 150mcg a day, but the dose can be lower than 50mcg or up to 300mcg a day, depending on your needs. […] Patience is needed as it can take several months before you feel better and for the thyroid function tests to return to normal or be judged satisfactory by your doctor.

  https://www.aafp.org/pubs/afp/issues/2001/1115/p1717.html

  The management of hypothyroidism focuses on ensuring that patients receive appropriate thyroid hormone replacement therapy and monitoring their response. […] Hormone replacement should be initiated in a low dosage, especially in the elderly and in patients prone to cardiac problems. The dosage should be increased gradually, and laboratory values should be monitored six to eight weeks after any dosage change. […] Once a stable dosage is achieved, annual monitoring of the thyroid-stimulating hormone (TSH) level is probably unnecessary, except in older patients. […] After full replacement of thyroxine (T4) using levothyroxine, the addition of triiodothyronine (T3) in a low dosage may be beneficial in some patients who continue to have mood or memory problems. […] Most otherwise healthy adult patients with hypothyroidism require thyroid hormone replacement in a dosage of 1.7 g per kg per day, with requirements falling to 1 g per kg per day in the elderly.

  Clinical benefits begin in 3-5 days and level off after 4-6 weeks. Achieving a TSH level within the reference range may take several months because of delayed readaptation of the hypothalamic-pituitary axis. In patients receiving treatment with LT4, dosing changes should be made every 4-6 weeks until the patients TSH is in target range. […] In patients with central (ie, pituitary or hypothalamic) hypothyroidism, T4 levels rather than TSH levels are used to guide treatment. In most cases, the free T4 level should be kept in the upper third of the reference range. […] After dosage stabilization, patients can be monitored with annual or semiannual clinical evaluations and TSH monitoring. Patients should be monitored for symptoms and signs of overtreatment, which include the following: Tachycardia, Palpitations, Atrial fibrillation, Nervousness, Tiredness, Headache, Increased excitability, Sleeplessness, Tremors, Possible angina.

  Hypothyroidism, or underactive thyroid, happens when your thyroid gland doesn’t make enough thyroid hormones to meet your body’s needs. […] But there are treatments that can help. […] The treatment for hypothyroidism is medicine to replace the hormone that your own thyroid can no longer make. About 6 to 8 weeks after you start taking the medicine, you will get a blood test to check your thyroid hormone level. Your health care provider will adjust your dose if needed. Each time your dose is adjusted, you’ll have another blood test. Once you find the right dose, you will probably get a blood test in 6 months. After that, you will need the test once a year. […] If you take your medicine according to the instructions, you usually should be able to control the hypothyroidism. You should never stop taking your medicine without talking with your health care provider first.

  Duration and dose—Your health care provider will prescribe an initial dose of levothyroxine and then retest your blood level of TSH after six weeks. Your dose can be adjusted at that time if needed. This process may need to be repeated several times before your hormone levels become normal. Color-coded tablets can help with dose adjustments. […] […] Thyroid hormone makes the heart work a bit harder. For this reason, most health care providers prescribe a lower initial dose of levothyroxine in older adults and in people with coronary artery disease. […] […] Once the optimal dose has been identified, your provider may recommend monitoring blood tests once yearly, or more often as needed. Most people with hypothyroidism require lifelong treatment, although the dose of levothyroxine may need to be adjusted over time. […]

  Youll need to have your TSH checked 6 to 10 weeks after a thyroxine dose change. You may need tests more often if youre pregnant or youre taking a medicine that interferes with your bodys ability to use thyroxine. The goal of treatment is to get and keep your TSH in the normal range. Babies with hypothyroidism must get all their daily treatments and have their TSH levels checked as they grow, to prevent mental retardation and stunted growth. Once youve settled into a thyroxine dose, you can return for TSH tests about once a year.

  The decision to treat subclinical hypothyroidism with levothyroxine is controversial. We treat all patients with a TSH >7 to 10 mU/L. The decision to treat patients with a TSH that is above the upper limit of normal (this cutoff can vary but is usually around 4.2 to 5 mU/L) but below 7 to 10 mU/L is based upon age and the presence of goiter (enlargement of the thyroid) or new or worsening symptoms of hypothyroidism. […] […] Younger people (under age 65 to 70 years) are frequently treated before the TSH exceeds 7 mU/L. In contrast, older adults with a similar slight elevation in TSH are often not treated. This is because the normal range for TSH is higher in older people, with an upper limit of approximately 7.5 mU/L in 80-year-olds. […] […] Adding liothyronine or thyroid extract—Some doctors treat hypothyroidism with liothyronine (T3) pills in addition to levothyroxine (T4). This is controversial because most studies have not found a benefit. However, this might be an option if your symptoms do not improve enough with levothyroxine alone. […] […] Thyroid extract (also called „desiccated” thyroid extract) is a product that contains both T4 and T3. But most experts do not recommend using this to treat hypothyroidism, because it has a high concentration of T3 and may not lead to the right balance of T4 and T3 in the blood.

  Reference ranges of serum TSH levels are higher in older populations (eg, 65 years), so higher serum TSH targets may be appropriate; per the American Thyroid Association (ATA), target serum TSH may be raised to 4-6 mIU/L in patients aged 70-80 years. […] A meta-analysis of randomized, controlled trials of T4-T3 combination therapy versus T4 monotherapy for treatment of clinical hypothyroidism found no difference in effectiveness between combination therapy and monotherapy with respect to side effects such as bodily pain, depression, fatigue, body weight, anxiety, quality of life, and total LDL and HDL cholesterol and triglyceride levels. […] A study of athyreotic patients found a high heterogeneity in these patients ability to produce T3 when treated with levothyroxine.

  For young, healthy people, healthcare providers will generally begin with what is estimated to be a full replacement dose of T4 (that is, a dose that is supposed to completely restore thyroid function to normal). The full replacement dose is estimated according to body weight and, for most people, is between 50 and 200 micrograms (mcg) per day. […] For older people or people who have coronary artery disease, thyroid replacement therapy is usually started gradually, beginning with 25 to 50 mcg daily and increasing over time. […] TSH levels are monitored to help optimize the dose of T4. […] While symptoms of hypothyroidism usually begin to resolve within two weeks of initiating treatment, it takes about six weeks for TSH levels to stabilize. […] If TSH levels remain above the target range, the dose of T4 is increased by about 12 to 25 mcg per day, and TSH levels are tested again after six more weeks.

• #32 Subclinical Hypothyroidism: Causes and Treatment | Doctor

  https://patient.info/doctor/subclinical-hypothyroidism

  Subclinical hypothyroidism is a common condition. Prevalence increases with age and is more common in women. Approximately 8% of women (10% of women over 55 years of age) and 3% of men have subclinical hypothyroidism. Treatment with thyroid hormones is increasing and more than 10-15% of people aged over 80 years are prescribed levothyroxine replacement therapy. […] A 2019 review and meta-analysis concluded that almost all adults with subclinical hypothyroidism would not benefit from treatment with thyroid hormones. However, the National Institute for Health and Care Excellence (NICE) committee found that most of the evidence related to older adults. The committee agreed that as most studies used 65 years as a cut-off it was appropriate to define older adults as over 65 and make separate recommendations for this group.

• #33 Subclinical Hypothyroidism: Causes and Treatment | Doctor

  https://patient.info/doctor/subclinical-hypothyroidism

  The NICE committee also noted that a TSH level above 10 mlU/L is more often associated with symptoms. They therefore agreed that levothyroxine should be considered for all adults with a TSH level of 10 mlU/L or more because this may improve symptoms and may have long-term benefits including on cardiovascular outcomes. […] Therefore the 2021 NICE Guidelines suggest that levothyroxine treatment should be considered for adults with subclinical hypothyroidism who have a TSH of 10 mlU/litre or higher on two separate occasions three months apart. A six-month trial of levothyroxine should also be considered for adults under 65 with SCH who have a TSH above the reference range but lower than 10 mlU/L on two separate occasions three months apart, and symptoms of hypothyroidism. […] Patients with a history of radio-iodine treatment or positive thyroid antibody test should be treated, as this subgroup will nearly always progress to overt hypothyroidism.

• #34 Hypothyroidism – Wikipedia

  https://en.wikipedia.org/wiki/Hypothyroidism

  Hypothyroidism is an endocrine disease in which the thyroid gland does not produce enough thyroid hormones. Thyroid hormone replacement with levothyroxine treats hypothyroidism. Medical professionals adjust the dose according to symptoms and normalization of the TSH levels. Thyroid medication is safe in pregnancy. There is no evidence of a benefit from treating subclinical hypothyroidism in those who are not pregnant, and there are potential risks of unnecessary overtreatment. American guidelines recommend that treatment should be considered in people with symptoms of hypothyroidism, detectable antibodies against thyroid peroxidase, a history of heart disease, or are at an increased risk for heart disease if the TSH is elevated but below 10 mIU/L. Myxedema coma or severe decompensated hypothyroidism usually requires admission to the intensive care, close observation and treatment of abnormalities in breathing, temperature control, blood pressure, and sodium levels. In women with known hypothyroidism who become pregnant, it is recommended that serum TSH levels are closely monitored. Levothyroxine should be used to keep TSH levels within the normal range for that trimester.

  The decision to treat subclinical hypothyroidism with levothyroxine is controversial. We treat all patients with a TSH >7 to 10 mU/L. The decision to treat patients with a TSH that is above the upper limit of normal (this cutoff can vary but is usually around 4.2 to 5 mU/L) but below 7 to 10 mU/L is based upon age and the presence of goiter (enlargement of the thyroid) or new or worsening symptoms of hypothyroidism. […] […] Younger people (under age 65 to 70 years) are frequently treated before the TSH exceeds 7 mU/L. In contrast, older adults with a similar slight elevation in TSH are often not treated. This is because the normal range for TSH is higher in older people, with an upper limit of approximately 7.5 mU/L in 80-year-olds. […] […] Adding liothyronine or thyroid extract—Some doctors treat hypothyroidism with liothyronine (T3) pills in addition to levothyroxine (T4). This is controversial because most studies have not found a benefit. However, this might be an option if your symptoms do not improve enough with levothyroxine alone. […] […] Thyroid extract (also called „desiccated” thyroid extract) is a product that contains both T4 and T3. But most experts do not recommend using this to treat hypothyroidism, because it has a high concentration of T3 and may not lead to the right balance of T4 and T3 in the blood.

  When mild hypothyroidism is treated, levothyroxine (T4) is the treatment of choice. […] A 2017 trial published in The New England Journal of Medicine found that treating people ages 65 and older for mild hypothyroidism doesn’t have much of a benefit. […] The authors say many older adults revert to normal thyroid function on their own, without treatment. […] A follow-up study recently published in the Annals of Internal Medicine analyzed data from patients enrolled in the 2017 NEJM study, and determined that even those with the greatest number of symptoms did not benefit. […] In addition to the possibility that the treatment may not offer any benefit, there are other reasons for caution. Overtreatment prescribing thyroid medication to someone with subclinical disease who may not need treatment, or giving excessive thyroid medication comes with serious risks, particularly thyrotoxicosis, the presence of too much thyroid hormone in the body. […] Long-term complications of even mild thyrotoxicosis can include heart problems and bone loss.

  Hypothyroidism cant be cured. But in almost every patient, hypothyroidism can be completely controlled. It is treated by replacing the amount of hormone that your own thyroid can no longer make, to bring your T4 and TSH levels back to normal levels. So even if your thyroid gland cant work right, T4 replacement can restore your bodys thyroid hormone levels and your bodys function. Synthetic thyroxine pills contain hormone exactly like the T4 that the thyroid gland itself makes. All hypothyroid patients except those with severe myxedema (life-threatening hypothyroidism) can be treated as outpatients, not having to be admitted to the hospital. For the few patients who do not feel completely normal taking a synthetic preparation of T4 alone, the addition of T3 (Cytomel) may be of benefit. […] The only dangers of thyroxine are caused by taking too little or too much. If you take too little, your hypothyroidism will continue. If you take too much, youll develop the symptoms of hyperthyroidisman overactive thyroid gland. The most common symptoms of too much thyroid hormone are fatigue but inability to sleep, greater appetite, nervousness, shakiness, feeling hot when other people are cold, and trouble exercising because of weak muscles, shortness of breath , and a racing, skipping heart. Patients who have hyperthyroid symptoms at any time during thyroxine replacement therapy should have their TSH tested. If it is low, indicating too much thyroid hormone, their dose needs to be lowered.

  Reference ranges of serum TSH levels are higher in older populations (eg, 65 years), so higher serum TSH targets may be appropriate; per the American Thyroid Association (ATA), target serum TSH may be raised to 4-6 mIU/L in patients aged 70-80 years. […] A meta-analysis of randomized, controlled trials of T4-T3 combination therapy versus T4 monotherapy for treatment of clinical hypothyroidism found no difference in effectiveness between combination therapy and monotherapy with respect to side effects such as bodily pain, depression, fatigue, body weight, anxiety, quality of life, and total LDL and HDL cholesterol and triglyceride levels. […] A study of athyreotic patients found a high heterogeneity in these patients ability to produce T3 when treated with levothyroxine. Approximately 20% of these athyreotic patients did not maintain normal free T4 or free T3 values despite a normal TSH.

  The decision to treat subclinical hypothyroidism with levothyroxine is controversial. We treat all patients with a TSH >7 to 10 mU/L. The decision to treat patients with a TSH that is above the upper limit of normal (this cutoff can vary but is usually around 4.2 to 5 mU/L) but below 7 to 10 mU/L is based upon age and the presence of goiter (enlargement of the thyroid) or new or worsening symptoms of hypothyroidism. […] […] Younger people (under age 65 to 70 years) are frequently treated before the TSH exceeds 7 mU/L. In contrast, older adults with a similar slight elevation in TSH are often not treated. This is because the normal range for TSH is higher in older people, with an upper limit of approximately 7.5 mU/L in 80-year-olds. […] […] Adding liothyronine or thyroid extract—Some doctors treat hypothyroidism with liothyronine (T3) pills in addition to levothyroxine (T4). This is controversial because most studies have not found a benefit. However, this might be an option if your symptoms do not improve enough with levothyroxine alone. […] […] Thyroid extract (also called „desiccated” thyroid extract) is a product that contains both T4 and T3. But most experts do not recommend using this to treat hypothyroidism, because it has a high concentration of T3 and may not lead to the right balance of T4 and T3 in the blood.

  When mild hypothyroidism is treated, levothyroxine (T4) is the treatment of choice. […] A 2017 trial published in The New England Journal of Medicine found that treating people ages 65 and older for mild hypothyroidism doesn’t have much of a benefit. […] The authors say many older adults revert to normal thyroid function on their own, without treatment. […] A follow-up study recently published in the Annals of Internal Medicine analyzed data from patients enrolled in the 2017 NEJM study, and determined that even those with the greatest number of symptoms did not benefit. […] In addition to the possibility that the treatment may not offer any benefit, there are other reasons for caution. Overtreatment prescribing thyroid medication to someone with subclinical disease who may not need treatment, or giving excessive thyroid medication comes with serious risks, particularly thyrotoxicosis, the presence of too much thyroid hormone in the body. […] Long-term complications of even mild thyrotoxicosis can include heart problems and bone loss.

• #67 Subclinical Hypothyroidism: Causes and Treatment | Doctor

  https://patient.info/doctor/subclinical-hypothyroidism

  A 2023 meta-analysis confirmed that the European Thyroid association guidance has clinical value and is slightly different from the earlier NICE guidance. The guidance is: To treat all patients with subclinical hypothyroidism who are under 65 and have symptoms. To withdraw treatment if the symptoms do not resolve and the TSH remains 10. To treat all patients with levothyroxine if their TSH is 10. To treat all patients with subclinical hypothyroidism, who have had a partial thyroidectomy or have a goitre, aiming for a TSH within the normal range. […] If the decision is made to treat: Levothyroxine is the drug of choice as it has a long half-life (seven days) and is partially converted to T3 in the body, resulting in a constant physiological level of both T3 and T4 with a single daily dose.

  The treatment goals for hypothyroidism are to reverse clinical progression and correct metabolic derangements, as evidenced by normal blood levels of thyroid-stimulating hormone (TSH) and free thyroxine (T4). Thyroid hormone is administered to supplement or replace endogenous production. In general, hypothyroidism can be adequately treated with a constant daily dose of levothyroxine (LT4). […] Thyroid hormone can be started at anticipated full replacement doses in individuals who are young and otherwise healthy (1.6 g/kg/day). Pregnant women will require doses about 25% higher. In elderly patients and those with known ischemic heart disease, treatment should begin with one fourth to one half the expected dosage, and the dosage should be adjusted in small increments after no less than 4-6 weeks.

  Hypothyroidism (underactive thyroid) is common and an increased TSH level and, usually, a low FT4 level make the diagnosis. Hypothyroidism is treated with thyroid hormone replacement, usually in the form of levothyroxine. The goal of treating hypothyroidism is achieving a TSH in the normal range, which is usually sufficient in relieved the symptoms of hypothyroidism. […] Both overtreatment and undertreatment of hypothyroidism with of thyroid hormone was linked to an increased risk of death due to heart disease. These data clearly show that it is important to keep the TSH levels in the normal range while on thyroid hormone in order to decrease the cardiac risk and death in those patients with hypothyroidism. […] Thyroid hormone therapy: patients with hypothyroidism are most often treated with Levothyroxine in order to return their thyroid hormone levels to normal. Replacement therapy means the goal is a TSH in the normal range and is the usual therapy. Suppressive therapy means that the goal is a TSH below the normal range and is used in thyroid cancer patients to prevent growth of any remaining cancer cells.
