Expert advice for Roxin Tablet
Your doctor has prescribed Roxin to replace the natural thyroid hormone that your own thyroid gland can no longer make. It is best to take Roxin on an empty stomach (ideally, first thing in the morning). No food, milk, or tea should be taken 1 hour before and 2 hours after taking this medicine. Though it starts working within 1 to 2 weeks, you may have to wait for 6 to 8 weeks to get the full effect. For most people, Roxin is a lifelong medication. Do not discontinue it without first discussing with your doctor. Inform your doctor if you have diarrhoea, nervousness, irritability, feeling of a heartbeat, sleep disturbances, shaking hands, or chest pain. Your doctor may adjust your dose. Leave a gap of at least 4 hours before taking any antacids, calcium or iron supplements, and multivitamins, as these may interfere with the effect of the medicine. Get your thyroid hormone and TSH levels checked regularly. Inform your doctor before changing the brand of Roxin as all brands may not have the same effect.

Frequently Asked Questions

Q. Can I take Roxin during pregnancy?
Thyroid hormone is naturally present in the body and is therefore safe to take in pregnancy. In fact, it is very important that pregnant women or those planning to become pregnant have normal thyroid hormone levels to provide a suitable environment for the baby. If you are already taking thyroid hormone, your dose may need to be increased during pregnancy. Hence, you may have to get your thyroid hormone and TSH levels measured once you know that you are pregnant. You should discuss the timing of thyroid blood tests with your doctor, but often thyroid tests are done every trimester.
