Taking 800mg of Viagra significantly exceeds the recommended dosage. This carries substantial risks. You could experience a prolonged and painful erection (priapism), requiring immediate medical attention to avoid permanent damage.
Cardiovascular Issues
High doses increase the risk of heart attack, stroke, and irregular heartbeat, particularly in individuals with pre-existing heart conditions. Chest pain, dizziness, or fainting should prompt immediate medical help. Consult your doctor before using Viagra, especially if you have heart problems.
Visual Disturbances
Vision changes, including blurred vision, temporary blue-tinted vision, or increased light sensitivity, are possible side effects. These usually resolve, but persistent issues need medical review.
Other Side Effects
Headaches, flushing, nasal congestion, and digestive upset are common, but 800mg increases the likelihood and severity. Severe allergic reactions, though rare, can occur; watch for swelling, hives, or breathing difficulties. Seek immediate medical care if such symptoms develop.
Dosage Recommendations
Always follow your doctor’s prescribed dosage. Self-adjusting dosage can lead to serious complications. Never exceed the recommended amount without explicit medical supervision. If you experience any unusual or concerning side effects, contact your doctor or seek emergency medical care immediately.
