Generic Viagra, like its brand-name counterpart, can cause side effects. Common ones include headache, flushing, nasal congestion, and upset stomach. These usually are mild and temporary.
More serious, though less common, side effects include vision changes (blurred vision, blue tint to vision), prolonged erection (priapism), and hearing loss. Seek immediate medical attention if you experience any of these.
Certain medications interact with Viagra. Always inform your doctor of all medications you take, including over-the-counter drugs and supplements. Below is a table highlighting some key interactions:
| Nitrates (e. g., nitroglycerin) | Dangerous drop in blood pressure | Do not take Viagra with nitrates. |
| Alpha-blockers (e. g., tamsulosin) | Increased risk of low blood pressure | Your doctor may adjust your dosage. |
| Certain antifungals (e. g., ketoconazole) | Increased Viagra levels in the blood | Your doctor may lower your Viagra dosage. |
| HIV protease inhibitors (e. g., ritonavir) | Increased Viagra levels in the blood | Your doctor may lower your Viagra dosage. |
