Both Levitra and alcohol can lower blood pressure. Drinking alcohol while taking Levitra may enhance the blood pressure-lowering effect, potentially causing symptoms like dizziness, lightheadedness, fainting, and an increased risk of heart palpitations. There is no direct contraindication between Levitra and alcohol, meaning you are not strictly prohibited from drinking alcohol while using Levitra. However, combining the two should be done cautiously and in moderation to avoid adverse effects. Alcohol is a depressant that can reduce sexual arousal, impact nerve function, and interfere with blood flow, which could counteract the effectiveness of Levitra.
