What is the recommended time to take Levothyroxine?

1. Before bedtime

2. After meals

3. First thing in the morning

4. At lunch

The correct answer is: First thing in the morning

Levothyroxine is a synthetic form of the thyroid hormone thyroxine, commonly prescribed for hypothyroidism. The recommended time to take Levothyroxine is first thing in the morning, which allows the body to absorb it more effectively. Taking it on an empty stomach ensures that food does not interfere with its absorption in the gastrointestinal tract. Additionally, the recommendation is to take Levothyroxine consistently at the same time each day to maintain stable hormone levels in the body. This helps prevent fluctuations that could lead to ineffective treatment. It is generally advised to wait at least 30 to 60 minutes after taking the medication before consuming any food or beverages to maximize its absorption. In contrast, taking Levothyroxine after meals or at lunch can alter its effectiveness due to potential interactions with dietary elements, such as calcium and iron, which can bind to the medication and prevent proper absorption. Taking it before bedtime may also not be optimal for similar reasons related to food intake and absorption timing.
