Contact your doctor if your condition changes or you experience increased side effects such as headache, nausea, dizziness, slurred speech, uncontrolled eye movements, visual disturbances, tremors, and/or problems with balance or coordination. Your doctor may be able to prescribe alternatives that do not interact or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications.
