SYNTHROID is very useful in treating hypothyroidism (low thyroid hormone), goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer.
Following the dosage instructions of your doctor is the best way to use any medication. If you are unsure or do not remember the instructions then you may read the medicine label for more detailed information.
Take SYNTHROID without a meal in empty stomach.
Please drink a full glass of water with SYNTHROID.
It is very important that you complete the dosage schedule and do not interrupt it in between without seeking prior consultation from your doctor.
Taking your medication at the same time each day is a tried and tested method to avoid missing any doses.
Drug Class and Mechanism
SYNTHROID is a replacement for a hormone that is normally produced by your thyroid gland to regulate the body's energy and metabolism and it is given when the thyroid does not produce enough of this hormone on its own.
Despite your best attempts at remembering, if you still miss out on a dose, then take it as soon as you remember about it. But keep in mind that you will have to adjust your next dose by spacing it out by 4 to 5 hours. If this is not possible, then the best thing to do would be to skip the missed dose and continue with your normal dosage schedule.
Never try to compensate for the missed dose by taking a double dose together. It may cause adverse effects.
Store SYNTHROID at room temperature between 68 and 77 degrees F(20 and 25 degrees C). Always keep it in a cool dark place that is not directly exposed to sources of heat or moisture and sunlight. Protect it from kids and pets.
Doctors advise against using SYNTHROID if you are allergic to any ingredient in it or if you have history of heart attack, chest pain (angina), adrenal gland problems, or elevated thyroid hormone levels that have not been treated.
Discuss your past/current medical history in detail with your doctor before beginning treatment with any new medication. If you are using any herbal supplements or over the counter medication, including vitamin pills, then mention it to your doctor.
Doctors may prescribe certain laboratory tests to determine how you have responded to treatment and to gauge the severity of the side effects of SYNTHROID. Please Keep all lab appointments and do not miss any tests.
Please inform your lab technician or surgeon that you are taking SYNTHROID before you undergo any emergency surgical procedure including dental operations.
SYNTHROID may cause harm to fetus.
If you are expecting a child or are planning to have a child in the near future, then consult your doctor before using SYNTHROID to discuss any possible threats to the unborn baby.
If you are a nursing mother and breast feed your baby, then too, seek consultation before using SYNTHROID as some drugs are excreted in the breast milk and may enter the baby.
