Let's take a minute to talk about your medication. This is Synthroid. Your body absorbs it best when taken on an empty stomach, so take each dose at least 30 minutes before eating or 2 hours after. Synthroid is used to replace or supplement low levels of thyroid hormones in your body, which are very important for normal metabolism, growth and development. It can take several weeks to start improving your symptoms, and the full effects from a dose can take a month or two. Your doctor will monitor your dose with labwork. Synthroid is generally well-tolerated, but at first there could be slight and temporary hair loss. This is normal and should go away. If you notice other effects, like changes in appetite, sleeplessness, feeling hot, a fast heartbeat or diarrhea, let your doctor know because these could be related to this medicine. Also, it is not recommended to take non-prescription weight loss products with Synthroid unless you are under the close supervision of your doctor. For best results, continue taking Synthroid, and follow your doctor's recommendations for labwork and monitoring.
