Table of contents:

Tirosint is a medication used to treat hypothyroidism, or an underactive thyroid. It contains levothyroxine sodium. Levothyroxine is a synthetic version of the thyroid hormone thyroxine (T4) and is typically taken orally as a capsule. It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Levothyroxine helps to restore normal levels of hormones in the body and can help improve symptoms associated with these conditions.

Levothyroxine is used to replace the hormone that is not being produced by the thyroid gland in sufficient quantities, which can cause symptoms such as fatigue, weight gain, cold intolerance, and dry skin. When taken as prescribed, levothyroxine can help patients manage their symptoms and improve their quality of life.

Uses and Dosage

Levothyroxine oral should be taken on an empty stomach, 30 to 60 minutes before breakfast for optimal efficacy. Swallow the capsule whole with a full glass (8 ounces) of water to prevent the tablet from dissolving too quickly and potentially swelling in your throat. Follow the dosing instructions provided by your healthcare provider and take the medication at the same time each day.

The dosage of Tirosint can vary depending on factors such as age, weight, and medical history, and should be determined by a healthcare provider. The recommended starting dose for adults with hypothyroidism is typically between 50 and 100 micrograms once a day, which may be gradually increased over several weeks. The recommended full replacement dose for adults diagnosed with hypothyroidism is around 1.6 mcg/kg/day based on ideal body weight or lean body mass.

Frequently Asked Questions (FAQ)

How long does Tirosint stay in your system?

The half-life of levothyroxine (including Tirosint) is about 6 to 7 days, meaning it can take several weeks for the medication to be fully eliminated from your system.

It may take several weeks for the full effects of Tirosint (or any form of levothyroxine) to be realized.

Can Tirosint cause weight loss?

Although weight loss can be a side effect of Tirosint in people taking it for low thyroid levels (hypothyroidism), it is not a guaranteed effect and may not be desirable for everyone.

Can iodine supplements help with hypothyroidism?

If the underactive thyroid is not caused by iodine deficiency, then iodine supplements give no benefit and should not be taken.
