The Best Time to Take Thyroid Medicine

Thyroid medicines are generally hormone replacement drugs that are used for an under-active thyroid (hypothyroidism). Such drugs need to be able to be absorbed in the body properly, otherwise they will not work. Timing is key when taking thyroid medicine.

Significance

Thyroid medication, as with other types of medicine, takes time to absorb in the stomach and throughout the rest of the body. Thyroid medicine should be taken on an empty stomach and at the same time every day for it to work properly.

Types

The most common types of thyroid medications are Levothyroxine and Synthroid, which are taken for the treatment of hypothyroidism.

Taking Other Medications

Other drugs and supplements can interfere with thyroid medicine and should be taken at least four hours after. Examples include calcium supplements, antacids, anti-reflux drugs and drugs for anti-cholesterol.

Food

Certain foods can also disrupt thyroid medication function and include calcium-enriched foods, cabbage, soybeans, kelp, kale and collard. Such foods should be taken several hours after thyroid medication and should be limited in quantity throughout the day.

Prevention/Solution

The best time to take thyroid medicine is in the morning after waking up and at least an hour before eating. This way, the body has time to absorb the medicine and there is less chance of interference between other medicines and foods.
