Always discuss potential side effects and interactions with your doctor before starting any medication. Common side effects of Viagra, Cialis, and Levitra include headache, flushing, nasal congestion, and upset stomach. Less frequent, but more serious, side effects might include vision changes (blurred vision or even temporary blindness), hearing loss, chest pain, and irregular heartbeat. Seek immediate medical attention if you experience these.
Medication Interactions
These medications can interact negatively with nitrates (used for chest pain), alpha-blockers (used for high blood pressure and prostate problems), and some antifungals. Combining them can dangerously lower blood pressure. Your doctor needs a complete medication history, including over-the-counter drugs and supplements, to assess potential risks. Grapefruit juice can also interact, affecting how your body processes these drugs.
Alcohol and Other Considerations
Excessive alcohol consumption can worsen side effects and reduce the effectiveness of these medications. Certain underlying health conditions, such as heart disease, stroke, or low blood pressure, may make these medications unsuitable. Open communication with your physician is crucial for safe and appropriate use.
