Nuedexta Overdose

If someone takes too much Nuedexta (dextromethorphan and quinidine), the effects may include hallucinations, an abnormal heart rhythm, or seizures. Due to these and other potentially serious effects, it is important to seek prompt medical attention if you or someone else may have taken an overdose. Treatment may involve administering activated charcoal, pumping the stomach, and providing supportive care.
