Consult your doctor before using Viagra or any medication. This is crucial for assessing your suitability and managing potential risks.
Common Side Effects
Viagra can cause headaches, facial flushing, nasal congestion, and indigestion. These effects are usually mild and temporary. More serious, though rare, side effects include vision changes (blurred vision, blue tint to vision), hearing loss, and prolonged erection (priapism), requiring immediate medical attention.
Serious Health Implications
Individuals with heart conditions, low blood pressure, or a history of stroke should exercise extreme caution. Viagra can interact negatively with nitrates, potentially leading to dangerously low blood pressure. Always inform your physician about all medications you are taking.
Medication Interactions
| Nitrates | Severe drop in blood pressure |
| Alpha-blockers | Dizziness, fainting |
| Certain Antifungal Medications | Increased Viagra levels in the blood |
This table provides a partial list; a complete interaction profile needs individual medical assessment.
Other Considerations
Long-Term Effects
Long-term effects of Viagra are still under investigation. Consistent use might increase the risk of some side effects over time. Regular check-ups with your doctor are highly recommended.
