Always discuss potential side effects and interactions with your doctor before starting any medication. Common side effects include headache, flushing, nasal congestion, and upset stomach. These are usually mild and temporary.
More serious, though rare, side effects may include vision changes (blurred vision, sudden vision loss), hearing changes (ringing in the ears, sudden hearing loss), chest pain, irregular heartbeat, and prolonged erection (priapism).
Seek immediate medical attention if you experience any of these serious side effects.
Certain medications can interact negatively with Ed medications. These include nitrates (used to treat angina), alpha-blockers (used to treat high blood pressure and enlarged prostate), and some antifungal medications. Combining these can cause a dangerous drop in blood pressure.
| Nitrates | Severe hypotension | Avoid concurrent use |
| Alpha-blockers | Hypotension, dizziness | Consult your doctor for dosage adjustments |
| Antifungal medications (e. g., ketoconazole, itraconazole) | Increased Ed medication levels | Doctor may adjust dosage |
| CYP3A4 inhibitors (e. g., grapefruit juice, some antibiotics) | Increased Ed medication levels | Monitor for side effects |
Grapefruit juice can also interact, increasing medication levels. It’s best to avoid it while taking Ed medication.
Always be honest with your doctor about all medications and supplements you’re taking, including herbal remedies. This helps ensure your safety and the effectiveness of your treatment.
