Tirosint contains the active ingredient levothyroxine sodium. It is a prescription medication used to treat hypothyroidism (an underactive thyroid), a condition where the thyroid gland does not produce enough thyroid hormone.
Thyroid hormones are important for regulating the body’s metabolism, energy levels, heart rate, body temperature, and many other essential functions. When thyroid hormone levels are too low, symptoms such as fatigue, weight changes, feeling cold, constipation, and low energy may occur.
Tirosint helps restore normal thyroid hormone levels by replacing the hormone that the body is unable to produce in sufficient amounts.
Hypothyroidism (underactive thyroid)
Tirosint is used to treat hypothyroidism in:
Hypothyroidism may occur due to conditions such as:
By replacing missing thyroid hormone, Tirosint helps improve symptoms associated with low thyroid function and supports normal body processes.
Tirosint belongs to a class of medications called thyroid hormones.
It contains levothyroxine, a synthetic version of thyroxine (T4), the hormone naturally produced by the thyroid gland.
Once absorbed, levothyroxine helps restore normal thyroid hormone levels, which supports:
Tirosint is often used as a long-term treatment for hypothyroidism. Many people require ongoing thyroid hormone replacement therapy to maintain normal thyroid function.
Your healthcare provider will determine the appropriate dose based on factors such as:
Regular blood tests, including thyroid-stimulating hormone (TSH) testing, are used to monitor treatment and ensure your dose remains appropriate.
Take Tirosint exactly as prescribed and do not stop or change your dose without speaking with your healthcare provider.
Take Tirosint exactly as prescribed by your healthcare provider.
Tirosint should usually be taken once daily on an empty stomach, preferably 30 to 60 minutes before breakfast. Taking it at the same time each day helps maintain consistent thyroid hormone levels and improves treatment effectiveness.
Swallow the capsule whole with a full glass of water (about 8 ounces). Do not crush, chew, or open the capsule, as this may affect how the medication is absorbed.
Follow your healthcare provider’s instructions carefully and do not change your dose or stop taking Tirosint without medical advice.
Certain foods, supplements, and medications can reduce how much levothyroxine your body absorbs.
Tell your healthcare provider and pharmacist about all medications, vitamins, and supplements you take, especially:
Your healthcare provider may recommend separating these products from Tirosint by several hours.
The appropriate dose of Tirosint varies from person to person and depends on factors such as:
For adults with newly diagnosed hypothyroidism, the typical starting dose may range from 50 to 100 micrograms once daily.
Your healthcare provider may gradually adjust your dose over several weeks based on blood test results, especially thyroid-stimulating hormone (TSH) levels, and how well your symptoms are controlled.
For otherwise healthy adults requiring full thyroid hormone replacement, the usual estimated dose is approximately 1.6 micrograms per kilogram of body weight per day, based on ideal body weight or lean body mass.
Because thyroid hormone levels change gradually, your healthcare provider will usually monitor your blood tests and adjust your dose as needed.
Do not increase, decrease, or stop taking Tirosint without first consulting your healthcare provider.
Tirosint (Levothyroxine) is available in the following forms and strength:
Medication interactions
Tirosint can interact with other medications, supplements, and certain products that may affect how well levothyroxine is absorbed or how it works in the body.
Before starting Tirosint, tell your healthcare provider and pharmacist about all products you take, including:
Your healthcare provider may recommend adjusting the timing of certain medications or monitoring your thyroid levels more closely.
Tirosint should only be used under the supervision of a healthcare provider for the treatment of thyroid hormone deficiency.
It should not be used for weight loss or the treatment of obesity in people with normal thyroid function. Using thyroid hormone for weight loss can cause serious and potentially life-threatening side effects.
Tirosint may not be appropriate for everyone.
Tell your healthcare provider if you have or have had:
Your healthcare provider may need to adjust your dose or treat certain conditions before starting Tirosint.
Your thyroid hormone needs may change during pregnancy.
If you are pregnant, planning to become pregnant, or breastfeeding, tell your healthcare provider. Your Tirosint dose may need to be adjusted to maintain appropriate thyroid hormone levels.
Do not change your dose during pregnancy without medical guidance.
Before taking Tirosint, tell your healthcare provider or pharmacist if you are allergic to levothyroxine or any other medications.
Tirosint may contain inactive ingredients that can cause allergic reactions or sensitivity in some people.
Ask your pharmacist if you have questions about the ingredients in your medication.
Tirosint has a long half-life of approximately 6 to 7 days in most people. Because of this, it may take several weeks for the medication to be fully cleared from the body after stopping treatment. The exact amount of time can vary depending on factors such as age, health conditions, thyroid function, and other medications being taken.
Tirosint begins working after you start taking it, but it may take several weeks for thyroid hormone levels to stabilize and for you to notice the full benefits. Your healthcare provider will usually monitor your thyroid blood tests, such as thyroid-stimulating hormone (TSH), about 6 to 8 weeks after starting treatment or changing your dose to determine if adjustments are needed. Continue taking Tirosint as prescribed, even if you do not notice immediate improvement.
Tirosint is not a weight-loss medication. If you have hypothyroidism, restoring thyroid hormone levels to the normal range may help improve symptoms related to an underactive thyroid, including changes in metabolism and weight. Some people may lose weight after starting treatment if their previous low thyroid hormone levels contributed to weight gain. However, weight loss is not guaranteed and should not be the goal of using Tirosint unless recommended by a healthcare provider. Using levothyroxine for weight loss in people with normal thyroid function can be dangerous and is not recommended.
Iodine supplements only help hypothyroidism caused by an iodine deficiency. In most cases of hypothyroidism, such as Hashimoto’s thyroiditis or thyroid removal, iodine supplements do not improve thyroid function and may not be beneficial. Do not take iodine supplements for hypothyroidism unless your healthcare provider recommends them.
Take Tirosint exactly as prescribed by your healthcare provider. It should usually be taken on an empty stomach, either 30 to 60 minutes before breakfast or at bedtime at least 3 hours after your last meal. Swallow the capsule whole with a full glass of water. Do not crush, chew, or open the capsule unless instructed by your healthcare provider. Avoid taking Tirosint at the same time as certain medications or supplements, including calcium or iron products, as they may reduce how well your body absorbs the medication. Follow your healthcare provider’s instructions regarding the timing of other medications and supplements.
Yes. Tirosint can be used during pregnancy when prescribed by a healthcare provider. Thyroid hormone requirements often increase during pregnancy, so your dose may need to be adjusted to maintain healthy thyroid hormone levels. If you are pregnant, planning to become pregnant, or become pregnant while taking Tirosint, inform your healthcare provider so your thyroid levels can be monitored and your dose adjusted if needed.
