Let your doctor know if you experience headache, confusion, vomiting, diarrhea, ringing in the ears, hearing loss, blurred or double vision, or sensitivity to light, as these may be signs and symptoms of excessive quiNIDine levels. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or fast or pounding heartbeats.
