Always consult your doctor before taking any medication, including generic Viagra. Certain side effects are possible.
Common Side Effects
- Headache Facial flushing Nasal congestion Indigestion Muscle aches Visual disturbances (blurred vision, changes in color perception)
These are usually mild and temporary. If they persist or worsen, seek medical advice immediately.
Serious Side Effects (Seek immediate medical attention):
- Prolonged erection (priapism) lasting more than four hours Sudden vision loss Sudden hearing loss Chest pain Irregular heartbeat Stroke
These are rare but require urgent medical intervention.
Drug Interactions:
Generic Viagra can interact negatively with several medications. Avoid combining it with:
Nitrates (used to treat angina): This combination can cause a dangerous drop in blood pressure. Alpha-blockers (used to treat high blood pressure or prostate problems): This combination may lead to significant low blood pressure. Certain antifungal medications (like ketoconazole and itraconazole): These can increase Viagra’s concentration in the blood, potentially intensifying side effects. HIV protease inhibitors (like ritonavir and indinavir): Similar to antifungals, these can elevate Viagra levels. Other medications for erectile dysfunction: Taking multiple ED medications simultaneously can be dangerous.
This list isn’t exhaustive; your doctor will provide a complete assessment of potential interactions based on your specific health profile and medication history. Always disclose all medications and supplements you’re taking.
Alcohol and Viagra:
Excessive alcohol consumption can worsen side effects and reduce the effectiveness of Viagra. Moderate alcohol intake is generally acceptable, but it’s best to consult your physician.
