Viagra, while effective for many, can cause side effects. These vary in severity and frequency. Common side effects include headache, facial flushing, nasal congestion, and indigestion. Less common, but still possible, are visual disturbances like blurred vision or changes in color perception.
Cardiovascular Side Effects
Viagra can lower blood pressure, so individuals with pre-existing heart conditions should discuss use with their doctor. Chest pain, irregular heartbeat, and dizziness are potential cardiovascular side effects requiring immediate medical attention.
Interactions with Other Medications
Several medications interact negatively with Viagra. This is crucial to understand to avoid dangerous complications. Specifically, avoid combining Viagra with nitrates (used to treat angina) as this can lead to dangerously low blood pressure.
- Nitrates: Never combine with Viagra. Alpha-blockers: May cause significant drop in blood pressure. Certain antifungals: Can increase Viagra’s blood levels. HIV protease inhibitors: Can alter Viagra’s metabolism.
Always inform your doctor about all medications, including over-the-counter drugs and supplements, before starting Viagra.
Rare but Serious Side Effects
Priapism (a prolonged and painful erection lasting more than four hours) is a rare but serious side effect requiring immediate medical help. Sudden hearing loss or vision loss are also rare possibilities. Consult your doctor immediately if any of these occur.
Before Taking Viagra
Discuss your medical history with your doctor. This includes heart conditions, liver or kidney problems, and any existing medications. Understand potential side effects and interactions. Follow your doctor’s prescribed dosage instructions precisely.
