Indications
- Synthroid is indicated for the treatment of hypothyroidism, a condition characterized by an underactive thyroid gland.
- It is prescribed to replace or supplement thyroid hormone levels in patients with insufficient thyroid function.
- Synthroid helps to alleviate symptoms associated with hypothyroidism, including fatigue, weight gain, cold intolerance, and dry skin.
- It may also be used in the management of certain types of goiter (enlarged thyroid gland) and thyroid cancer, as part of a comprehensive treatment regimen.
Dosage and administration
- The dosage of Synthroid varies depending on the individual’s age, weight, thyroid hormone levels, and response to treatment.
- Synthroid is typically taken orally in tablet form, once daily on an empty stomach, at least 30 minutes to 1 hour before breakfast.
- The tablets should be swallowed whole with a full glass of water to ensure proper absorption of the medication.
- The starting dose of Synthroid for adults with hypothyroidism is often based on body weight, typically ranging from 1.6 to 1.8 micrograms per kilogram of body weight per day.
- For elderly patients or those with underlying cardiovascular disease, the initial dose may be lower to minimize the risk of cardiac complications.
- Children’s doses are based on age and weight and should be determined by a healthcare provider.
- Your healthcare provider may adjust the dosage of Synthroid based on periodic thyroid function tests and symptom improvement.
- It is important to take Synthroid regularly and at the same time each day to maintain stable thyroid hormone levels.
- Do not abruptly stop taking Synthroid without consulting your healthcare provider, as this can lead to a sudden worsening of symptoms or other serious complications.
- If you miss a dose of Synthroid, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular dosing schedule.
- Do not double the dose to make up for a missed one. Contact your healthcare provider if you have missed several doses or are unsure about what to do.
Side effects
- Common side effects of Synthroid may include headache, nervousness, or irritability.
- Some individuals may experience temporary hair loss, muscle weakness, or changes in appetite while taking Synthroid.
- Synthroid can cause symptoms of hyperthyroidism, such as increased heart rate, palpitations, or heat intolerance, especially if the dosage is too high.
- It may also lead to insomnia, tremors, or diarrhea in some people.
- Rarely, allergic reactions such as rash, itching, or swelling of the face, lips, or throat may occur with the use of Synthroid.
- Contact your healthcare provider if you experience any persistent or severe side effects while taking Synthroid.
Precautions
- Inform your healthcare provider about any existing medical conditions, especially heart disease, diabetes, or adrenal gland disorders, before taking Synthroid.
- Let your healthcare provider know if you are pregnant, planning to become pregnant, or breastfeeding, as Synthroid dosage may need adjustment during pregnancy and lactation.
- Inform your healthcare provider if you have a history of allergies to medications or any other substances, as Synthroid may contain inactive ingredients that can cause allergic reactions.
- Take precautions if you have a history of cardiovascular disease, as Synthroid may increase the risk of heart-related complications, especially when starting treatment or adjusting the dosage.
- Use caution when taking Synthroid in elderly patients or those with underlying cardiovascular conditions, as they may be more sensitive to the effects of thyroid hormone replacement therapy.
- Avoid sudden changes in dosage or abrupt discontinuation of Synthroid without consulting your healthcare provider, as this can lead to a sudden worsening of symptoms or other serious complications.
- Inform your healthcare provider about all medications, supplements, and herbal remedies you are taking, as they may interact with Synthroid and affect its effectiveness or increase the risk of side effects.
- Take Synthroid as directed by your healthcare provider, and do not exceed the prescribed dosage or duration of treatment.
- Store Synthroid at room temperature away from moisture and heat and keep it out of reach of children and pets.
