Synthroid is a type of thyroid hormone used in the treatment of low thyroid levels. This drug is used when the thyroid is incapable of producing sufficient hormones.
This type of hormone can be taken orally in the form of a tablet or as an injection into the body. If you are receiving this drug as an injection, make sure it is done by a qualified professional.
Common side effects associated with Synthroid include clumsiness, constipation, muscle ache and pains, fatigue, weakness, weight gain, chills and diarrhea. If the effects do not go away within a week, contact your doctor.
Synthroid can also be used to decrease the size of enlarged thyroid glands, treat thyroid cancer, and other purposes, as directed by your doctor.
