This can cause nausea, seizures, numbness or tingling, tiredness, dizziness, a loss of consciousness, and a worsening irregular heartbeat. Use caution when driving, operating machinery, or performing other hazardous activities. Mexiletine may cause drowsiness and blurred vision. If you experience dizziness, drowsiness, or blurred vision, avoid these activities. You may need a dose adjustment or special test if you use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
