Description

Overview
Levothyroxine is a thyroid hormone replacement used to treat hypothyroidism, a condition where the thyroid does not produce enough hormones. It can also improve mood and energy levels in people with thyroid-related depression.

Mechanism of Action
Levothyroxine is a synthetic form of thyroxine (T4), which the body converts into the active thyroid hormone triiodothyronine (T3). It restores normal metabolic function and energy levels.

• Hashimoto’s thyroiditis – Helps replace lost thyroid function.

Possible Side Effects
