Always consult your doctor before using Viagra or any generic alternative. Discuss your medical history, including existing conditions like heart problems, high or low blood pressure, liver or kidney disease, and eye problems. Certain medications can interact negatively with Viagra, so provide a complete list of your current prescriptions and over-the-counter drugs.
Common Side Effects
Be aware of potential side effects such as headaches, facial flushing, nasal congestion, indigestion, and visual disturbances. These are usually mild and temporary. However, seek immediate medical attention if you experience chest pain, prolonged erection (priapism), sudden vision loss, or hearing loss. These are serious and require prompt medical care.
Safe Usage
Follow the prescribed dosage precisely. Do not exceed the recommended amount or frequency. Avoid alcohol consumption in excess as it can enhance side effects. Grapefruit juice can also interact negatively with Viagra, therefore you should avoid it. Inform your doctor about any changes in your health status during treatment.
