Consult your doctor before using Viagra, especially if you have heart problems, high or low blood pressure, kidney or liver disease, or a history of stroke. Viagra can interact with other medications, so provide your doctor with a complete list of your current prescriptions and over-the-counter drugs.
Side Effects
Common side effects include headaches, flushing, nasal congestion, and upset stomach. More serious, though less common, side effects include vision changes (blurred vision, blue-tinged vision), hearing loss, and prolonged erections (priapism), requiring immediate medical attention. Inform your physician about any unusual symptoms you experience.
Precautions
Viagra isn’t suitable for everyone. Men with certain eye conditions, such as retinitis pigmentosa, should avoid it. Grapefruit juice can significantly increase Viagra’s concentration in your blood, potentially leading to adverse effects – avoid combining them. Alcohol consumption can also intensify side effects; moderate your intake.
Alternatives
If Viagra isn’t right for you, discuss alternative treatments for erectile dysfunction with your doctor. Several other medications and therapies are available. Open communication with your healthcare provider is key to finding a safe and effective solution.
Long-Term Use
Regular use of Viagra requires ongoing monitoring by your physician. Long-term effects aren’t fully understood, so regular checkups are recommended to assess your overall health and adjust treatment as needed. Don’t self-prescribe or exceed the recommended dosage.
