Facts on Synthroid

1. Sometimes Synthroid Is Risky Business

Most people tolerate Synthroid well, especially since our bodies make their own thyroid hormone. There are, however, certain conditions that might make taking Synthroid contraindicated. Don't take Synthroid if you have a history of heart attack or thyrotoxicosis, which is a disorder of the thyroid gland. You should also have any adrenal gland function problems well under control before taking Synthroid. Certain other diseases also may make taking Synthroid more risky. If you have heart disease, diabetes, coronary artery disease, a history of anemia or blot clots or problems with your pituitary gland, talk to your doctor about the risks and benefits of taking Synthroid.

2. Expecting? Expect to Increase Your Synthroid Dose

Synthroid is a pregnancy category A in the medical reference books. This means it's safe to take during pregnancy and while nursing. Drugs are classified in categories A, B, C and D, where A is not harmful and D is known to cause birth defects. Not only is Synthroid OK to take while pregnant or nursing, but you may also actually need to increase your dose because of the increased demand during these times.

3. Side Effects May Actually Be an Overdose

Be sure to take your Synthroid exactly as your doctor has prescribed and tell him about any side effects you are experiencing so he can adjust your dose as necessary. Side effects of too much Synthroid can include tremors, confusion, chest pain, pounding heartbeat, leg craps, shortness of breath, digestive problems and even seizures. Any of these symptoms may be an indication of an overdose, so discuss any and all symptoms you experience while on Synthroid therapy with your doctor.

4. Synthroid Doesn't Mix With Some Foods

As strange as it may seem, you'll need to avoid certain foods that can interact with Synthroid therapy. High fiber foods, such as bran, need to be avoided, as do walnuts, cotton seed meal and soy infant formula. All these foods can make your body absorb less of the Synthroid, which in turn will lower your blood levels. Ask your doctor how often you'll need to get your hormone blood levels checked, and make sure you have them checked as often as needed.

5. Seeking Emergency Assistance

Anyone can become allergic to anything at any time, including to Synthroid. Keep a watch out for allergic reactions such as hives, difficulty breathing or swelling, especially of the face, tongue, lips or throat. These symptoms require emergency medical treatment. Call your doctor right away if you have headache, insomnia, nervousness, irritability, fever, hot flashes, changes in your menstrual cycle, sweating or appetite or weight changes. All of these symptoms could be a sign of a serious medical condition and should be addressed by your doctor right away.
