How To Take Levothyroxine
Levothyroxine controls hypothyroidism but does not cure it. It may take several weeks before you notice a change in your symptoms. Continue to take levothyroxine even if you feel well. Do not stop taking levothyroxine without talking to your doctor. Your doctor will probably start you on a low dose of levothyroxine and gradually increase your dose. Levothyroxine comes as a tablet to take by mouth.
