1. Radioactive iodine drink which is taken by mouth will cause your overactive thyroid gland to  shrink and stop producing the thyroid hormone.  Symptoms usually improve within a few months but you may need to take replacement thyroid hormone medication at a later date.

2. Anti-thyroid medications can stop your thyroid gland from overproducing thyroid hormones.  These include Methimazole (Tapazole) and Propylithiouracil.  These need to be prescribed by your doctor because the dosage depends on your blood test results and doctor’s examination.

3. Beta blocker medication to improve the tremor and reduce your heart rate and palpitations.

4. Surgery (thyroidectomy) to remove your overactive goitre gland
