Sildenafil citrate, while generally safe, can cause side effects. Common ones include headache, facial flushing, nasal congestion, and indigestion. These usually are mild and temporary.
More serious, though rare, side effects include vision changes (blurred vision, blue-tinged vision), prolonged erection (priapism), and hearing loss. Seek immediate medical attention if you experience any of these.
Certain medications can interact negatively with sildenafil. This includes nitrates (used to treat chest pain), alpha-blockers (used to treat high blood pressure), and some antifungal medications. Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements.
| Nitrates | Dangerous drop in blood pressure |
| Alpha-blockers | Dizziness, fainting |
| Antifungal medications (like ketoconazole, itraconazole) | Increased sildenafil levels, raising the risk of side effects |
Drinking excessive alcohol can worsen side effects. Avoid grapefruit juice, as it can increase sildenafil levels in your body. Consult your doctor before starting sildenafil, especially if you have pre-existing health conditions like heart problems or high blood pressure. He or she can help determine if it’s a safe option for you and discuss potential risks and benefits.
