Consult your doctor before using Viagra or any similar medication. This is particularly important if you have heart problems, high or low blood pressure, a history of stroke, kidney or liver disease, or blood cell disorders. Certain medications, like nitrates, interact dangerously with Viagra. Inform your physician about all medications you currently take, including supplements and herbal remedies, to avoid harmful interactions.
Common Side Effects
The most common side effects include headache, flushing, nasal congestion, and upset stomach. These are usually mild and temporary. Vision changes, such as blurred vision or sensitivity to light, may also occur. If you experience prolonged or painful erections (priapism), seek immediate medical attention. This is a serious condition requiring prompt treatment.
Rare but Serious Side Effects
Less common, but serious, side effects include a sudden decrease or loss of vision or hearing, and allergic reactions (such as rash, hives, or swelling). If you notice any of these, discontinue use and contact your doctor immediately. Remember, this information is not a substitute for professional medical advice. Always follow your doctor’s instructions.
