Medithyrox
Medithyrox is a synthetic thyroid hormone used to treat various thyroid conditions by mimicking the body's natural hormone.
How to Use
Dosage
Your doctor will decide your exact dose based on tests. For adults, typical daily doses range from 25 to 300 micrograms, depending on your health condition. For babies with an underactive thyroid, the starting dose is usually 10-15 micrograms per kilogram of body weight each day for the first 3 months.
Method
Take Medithyrox orally once a day in the morning on an empty stomach, at least half an hour before breakfast, preferably with a small amount of liquid (e.g., half a glass of water). For infants, crush the tablet just before use and mix with a small amount of water, giving it to the child at least half an hour before the first feeding.
The maximum daily dose is determined by your doctor, but typical doses generally do not exceed 300 micrograms.
