Most of the side effects are symptoms of hyperthyroidism and it usually means your dose is too high. If you have any of the listed side effects, talk to your provider; they might need to lower your dose. Unlike other medications, not all generic forms of Synthroid (levothyroxine) are the same. Try to fill this medication at the same pharmacy every month and pay attention to the manufacturer. You might not be able to change the manufacturer the pharmacy uses, but you can talk to your provider about changing your dose if needed. Don't stop taking Synthroid (levothyroxine) without talking to your provider first. They might need to lower your dose gradually.
