Levothyroxine is used to treat hypothyroidism, when the thyroid gland does not produce enough thyroid hormone. It can also be used in surgery and radioactive iodine therapy to treat thyroid cancer. Levothyroxine is a class of drugs called hormones. Its job is to replace thyroid hormones normally produced by the body.
Without thyroid hormones, your body cannot function properly, which can lead to poor growth, slow speech, low energy, fatigue, constipation, weight gain, hair loss, dryness, thick skin, increased susceptibility to colds, joint and muscle pain, severe or irregular menstruation, and depression. If taken correctly, levothyroxine reverses these symptoms.
Levothyroxine (thyroid hormone) should not be used alone or in combination with other treatments to treat obesity or cause weight loss.At high doses, levothyroxine can cause serious or life-threatening problems, especially when taken with amphetamines such as Adzenys, Dyanavel XR, Evekeo, Dexedrine and Desoxyn. If you experience any of the following symptoms while taking levothyroxine, tell your doctor: chest pain, rapid or irregular heartbeat or pulse, uncontrollable shaking in certain parts of the body, nervousness, anxiety, irritability, difficulty sleeping or falling asleep, short body size, excessive sweating.
Levothyroxine is a tablet and capsule that can be taken orally. It is usually taken once a day on an empty stomach, 30 minutes to an hour before breakfast. Please follow the instructions on the prescription label carefully and ask your doctor or pharmacist to explain any areas you do not understand. Levothyroxine was administered exactly as directed.
