Levothyroxine side effects?

• I have to take Levothyroxine for my thyroid, but I am afraid to cause of all the side effects. How can I avoid the side effects when I take my medicine?

• Answer:

  Remember that it is always best to consult your doctor or healthcare specialist for medical advice and that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. From every source that I've looked at so far, all of them say that most people using this medication do not have serious side effects, that they are rare and that generally no or very very minor side effects are seen. Possible side effects include: Severe allergic reactions (rash; hives; itching; difficulty breathing; flushing; tightness in the chest; swelling of the mouth, face, lips, or tongue; unusual hoarseness); changes in appetite; changes in menstrual periods; chest pain; diarrhea; excessive sweating; fast or irregular heartbeat; fever; heat intolerance; joint pain; leg cramps; mental or mood changes (eg, anxiety, irritability, nervousness); muscle weakness; seizures; severe or persistent headache or fatigue; shortness of breath; stomach cramps; tremors; trouble sleeping; unusual weight gain or weight loss; vomiting; wheezing.
