Consult your doctor before using Viagra, especially if you have heart problems, high or low blood pressure, or liver/kidney disease. Viagra can interact negatively with certain medications, including nitrates.
Common Side Effects
Many men experience mild side effects. These often include headaches, flushing, nasal congestion, and upset stomach. These usually resolve on their own. However, if they persist or worsen, seek medical attention.
Less Common but Serious Side Effects
Vision changes, such as blurred vision or temporary blue-tinged vision, are possible. Hearing problems, including ringing in the ears (tinnitus) and sudden hearing loss, though rare, require immediate medical evaluation. Prolonged erections (priapism) are a medical emergency and demand immediate attention; this can cause permanent damage. Heart problems, such as chest pain or irregular heartbeat, necessitate immediate medical help.
Precautions and Interactions
Avoid alcohol while using Viagra, as it can exacerbate side effects. Inform your doctor about all medications you take. Viagra’s interaction with other drugs can be dangerous. Avoid grapefruit and grapefruit juice, as they can increase Viagra’s concentration in your blood, potentially increasing the risk of side effects.
When to Seek Medical Help
Seek immediate medical help if you experience chest pain, dizziness, sudden vision loss, prolonged erection, or severe allergic reactions (rash, itching, swelling).
