1. About levothyroxine. Levothyroxine is a medicine used to treat an underactive thyroid gland (hypothyroidism). The thyroid gland makes thyroid hormone which helps to control energy levels and growth.

What condition do you take thyroxine for?

Levothyroxine is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery.

When should you take thyroxine?

Typically, patients are advised to take their levothyroxine first thing in the morning, at least 30 minutes but preferably an hour before eating, on an empty stomach and with only water. The goal is to achieve consistency in taking the medication to avoid fluctuations in thyroid levels and variable control of symptoms.
