Synthroid is a brand name for levothyroxine, a synthetic thyroid hormone responsible for the bodies metabolism. Synthroid is given as a treatment for hypothyroidism, which is a disorder whereby the thyroid gland has stopped producing enough thyroid hormone. This condition causes the body's rate of metabolism to drop, with resulting negative effects on its reproductive system. Symptoms of hypothyroidism include fatigue, swallowing difficulty, wild mood swings, hoarse voice, forgetfulness, sensitivity to cold and dry/coarse hair and skin. Synthroid has to be cautiously prescribed by a doctor as a supplement or replacement, in order to restore the delicate balance of the thyroid hormone in your body.

When undergoing a Synthroid treatment, avoid the following food products, which can cause your body to absorb less of this synthetic hormone: infant soy formula, cottonseed meal, walnuts, and high-fiber foods. Make sure not to change brands without first asking your doctor as different brands of levothyroxine may work differently for the same patient. Therefore, if you have a prescription refill with different looking pills inside than what you are used to, you would need to talk to your doctor or the pharmacist.

If you overdose on Synthroid, seek medical attention immediately. You will get these symptoms on overdose of this medicine: chest pain, pounding heartbeat, shortness of breath, tremor, leg cramps, confusion, vomiting, diarrhea, or seizures. In addition, should you have missed a dose on Synthroid, do not double up on it on your next dosage. Keep to a regularly scheduled time with the prescribed dosage, never to add extra to make up for any missed dose. Your doctor may change the dosage required over time to get the best results, follow the instructions properly. Do not continue taking the dosage for longer than what the doctor prescribed.

Take Synthroid 30 minutes before eating, preferably in the morning, and remember to take it at the same time each day, according to doctor's instructions. It is important that you take Synthroid with a full glass (8 ounces) of water, as the tablet can dissolve very quickly and swell in your throat causing gagging or choking. You will need to schedule regular visits to your doctor for blood, liver, or kidney tests while undergoing this treatment, and do not forget these scheduled visits. You would also need to inform any other doctor or dentist you are visiting, that you are using Synthroid.

Once you are on Synthroid however, chances are high that you will continue taking it for the rest of your life. If you take levothyroxine for long periods of time, it may cause loss of bone, leading to osteoporosis. Be sure this possibility is addressed when talking to your doctor.

Other things you need to discuss before taking Synthroid include if you have any history of heart disease, coronary artery disease, anemia, diabetes, adrenal or pituitary gland problems, or blood clots.
