Avoid taking generic Viagra with nitrates. This combination can cause a dangerous drop in blood pressure, leading to dizziness, fainting, or even a heart attack. Nitrates are found in medications for chest pain (like nitroglycerin) and some recreational drugs called “poppers.”
Be cautious when combining generic Viagra with alpha-blockers, often prescribed for high blood pressure or prostate problems. This combination can also significantly lower blood pressure. Talk to your doctor before taking them together.
Specific Medications to Discuss with Your Doctor:
Before starting generic Viagra, inform your doctor about all medications you are taking, including:
- Antibiotics, particularly erythromycin and clarithromycin. Antifungal medications like ketoconazole and itraconazole. HIV protease inhibitors. Certain antidepressants.
These medications can interact with generic Viagra and potentially affect its effectiveness or increase the risk of side effects. Your doctor can help you manage these potential interactions safely. Always be upfront about your complete medical history and current medications to minimize the risk of complications.
