Typical dosage for Mexiletine

The typical starting dose is 200 mg by mouth every 8 hours with food or an antacid. Your provider might adjust your dose every 2 to 3 days based on your heart rhythm. The maximum dose is 400 mg every 8 hours. Sometimes, your provider might ask you to take this medication every 12 hours instead (but keeping the same total daily dose).

Please note that your dose might differ if you have liver problems, if you experience side effects, or if you were taking other antiarrhythmics previously.
