It is important to note that there are medications that may affect the effectiveness of levothyroxine, so a patient needs to inform the doctor early if he or she is using other prescription drugs. While on medication, a person will need to visit a doctor on a regular basis to check his or her thyroid hormone levels. The doctor may adjust the dosage from time to time depending on the response to the medication, as stated by WebMD. A person may need to stay on the treatment for the rest of their lives.

Also called hypothyroidism, underactive thyroid is a condition characterized by poor or low production of thyroid hormone by the thyroid glands. Common symptoms of this condition include depression, tiredness and weight gain. This condition is not serious as most people start feeling better after taking hormone-replacement medications. If not treated early enough, hypothyroidism can lead to obesity, goiter, heart disease, infertility and joint pain.
