Thyroid hormone levothyroxine

Levothyroxine is a prescription medication and its dosage is adjusted via regular blood tests (TSH level). After making your selection, you will complete the medical questionnaire in full, and a doctor will then decide whether the treatment is suitable for you.

Is this treatment suitable for you?

  1. 1 The treatment may be suitable if you are already taking levothyroxine and have current blood test results. If you have been medically diagnosed with hypothyroidism, are on a stable dose, and have a TSH level from the last 12 months, a repeat prescription may be possible. Please specify the medication and daily dose in the questionnaire and upload your most recent lab results, if available. The doctor will decide.
  2. 2 Consult a doctor beforehand if you only suspect you have an underactive thyroid and your thyroid levels have not yet been determined. Fatigue or weight gain often have other causes, and levothyroxine must not be taken if hyperthyroidism has gone undiagnosed. Therefore, thyroid levels are first checked at a doctor's office. The doctor will then decide on any subsequent treatment.
  3. 3 When starting a new treatment or changing the medication A new medication regimen starts with a low dose and is adjusted every few weeks based on blood tests performed at a doctor's office. After switching medications, the TSH level is checked after approximately 6 to 8 weeks. The doctor decides whether a prescription is possible.
  4. 4 For heart disease, osteoporosis, pregnancy or desire to have children Then particularly careful evaluation is necessary, for example, starting with a low dose in cases of heart disease or close monitoring during pregnancy. Levothyroxine is not suitable after a recent heart attack. Please provide complete information in the questionnaire. The doctor will decide.

What you should know about the thyroid gland

Hypothyroidism is usually treated long-term and requires regular blood tests. Levothyroxine replaces the missing hormone, but a medical evaluation of new symptoms is not necessary.

What is hypothyroidism?

The thyroid gland produces the hormones thyroxine (T4) and triiodothyronine (T3), which help regulate metabolism, heartbeat, and body temperature. In an underactive thyroid (hypothyroidism), these hormones are deficient. Possible symptoms include:

  • Fatigue, lack of motivation and sensitivity to cold
  • Weight gain, constipation and dry skin
  • low mood or menstrual irregularities

Common causes include chronic inflammation of the thyroid gland (Hashimoto's thyroiditis), as well as surgery or radioiodine therapy. Because the symptoms can also have other causes, the diagnosis is always made via blood tests, especially the TSH level and free T4 (fT4).

Treatment with levothyroxine

Levothyroxine is a synthetically produced thyroid hormone and is identical to the body's own thyroxine. In the body, it is converted into the active hormone T3. According to the product information, it is used:

  • to replace the missing hormone in hypothyroidism
  • For benign enlargement of the thyroid gland (goiter) with normal function and for prevention after its surgery
  • for follow-up treatment in thyroid cancer, coordinated with the specialist practice

The dose is adjusted gradually based on the TSH level, and a change only takes full effect after several weeks. Treatment usually lasts a long time, often lifelong. Levothyroxine is not suitable for weight loss.

Side effects and cautions

Levothyroxine is generally well tolerated when taken at the appropriate dose. Side effects primarily occur when the dose is too high: palpitations, restlessness, sleep disturbances, tremors, sweating, diarrhea, or weight loss. A consistently high dose can contribute to heart rhythm disorders such as atrial fibrillation and osteoporosis.

Levothyroxine should not be taken in cases of untreated hyperthyroidism, untreated adrenal insufficiency or hypopituitarism, after a recent heart attack, or in cases of acute myocarditis. Calcium, iron, and antacids reduce its absorption. The effects of blood thinners and diabetes medications may be altered.

When should you see a doctor immediately?

Call emergency services immediately on 112 (Switzerland: 144) if:

  • Pain or tightness in the chest occurs
  • Swelling of the face, lips or throat, or shortness of breath occurs
  • a seizure occurs or fever sets in with severe restlessness, confusion and rapid heartbeat

Seek immediate medical advice if you experience a very rapid or irregular heartbeat or severe headaches accompanied by visual disturbances. You should also discuss palpitations, tremors, excessive sweating, or unintentional weight loss promptly, as the dose may be too high. This also applies if symptoms of hypothyroidism recur or if you become pregnant.

Levothyroxine in everyday life

Plan your daily intake carefully.

Levothyroxine works most consistently when taken according to the same routine every day. Even small differences in the time of day, breakfast, or the specific product can alter TSH levels because the range between too little and too much hormone is very narrow. A consistent morning routine helps, for example, keeping the pack next to your toothbrush.

  • Take the tablet in the morning on an empty stomach with water and wait at least 30 minutes before breakfast.
  • Take calcium, iron, magnesium, and heartburn medication at least 2 hours later.
  • Beware of high-dose biotin before blood tests, as it can distort lab results.

A missed dose is not taken twice; simply continue with the usual dose the following morning. Soy products can reduce absorption, so avoid sudden and drastic changes to your diet. If you are planning a pregnancy, it is advisable to have your thyroid levels checked beforehand. More information can be found here: Fertility. Our online doctor answers general questions..

Frage an einen ArztAsk a doctorPoser une question à un médecinVraag stellen aan een arts
Do I need a prescription for levothyroxine?

Yes. Levothyroxine is available by prescription only in all strengths. The questionnaire asks for information such as your diagnosis, current medication, daily dose, and your most recent TSH level, and you can upload a current lab report. A licensed physician will review your information. If the treatment is not suitable, no prescription will be issued, and all payments made will be fully refunded.

The tablet is swallowed once daily in the morning on an empty stomach with some water, at least 30 minutes before breakfast. A minimum of 2 hours should be allowed between taking it and taking calcium, iron, magnesium, or antacids. Treatment should not be stopped without consulting a doctor. The appropriate strength and daily dose will be determined by your doctor based on your blood test results.

Switching medications is possible, but should not be done without consulting a doctor. With levothyroxine, the appropriate and excessive doses are very close, so even small differences between preparations can alter the TSH level. If possible, continue taking the same preparation. After switching, the TSH level should be checked again after about 6 to 8 weeks. Please indicate your current medication in the questionnaire.

No. According to the product information, thyroid hormones should not be used for weight loss. With normal thyroid function, standard doses do not lead to weight loss, while higher doses can cause serious side effects affecting the heart. Therefore, levothyroxine is not prescribed for this purpose. If you experience fatigue or weight gain, the cause should first be investigated through blood tests at your general practitioner's office.

Yes, according to the product information, levothyroxine is continued during pregnancy and breastfeeding. During pregnancy, the need for levothyroxine often increases, so close blood monitoring and usually a dose adjustment are necessary. Inform your doctor immediately if you become pregnant. Combining levothyroxine with thyroid-blocking medications such as thiamazole is not permitted during pregnancy. If you are planning a pregnancy, it is best to have your thyroid levels checked beforehand.
