Viagra, or sildenafil, helps improve blood flow to the penis, aiding in achieving an erection. However, like all medications, it can cause side effects. Common ones include headaches, flushing, nasal congestion, and upset stomach. These are usually mild and temporary.
More Serious Side Effects
Less common, but more serious side effects require immediate medical attention. These include chest pain, irregular heartbeat, sudden vision loss or hearing loss, and prolonged erection (priapism). Seek medical help if you experience any of these.
Certain medical conditions can increase your risk of side effects. Individuals with heart problems, low blood pressure, or a history of stroke should discuss Viagra use with their doctor before taking it. Also, inform your doctor about all other medications you are taking, including over-the-counter drugs and supplements, as interactions can occur.
While Viagra is generally safe when used as directed, it’s crucial to follow your doctor’s instructions carefully. The correct dosage is vital for maximizing benefits and minimizing risks. Don’t exceed the recommended dose, and always consult your healthcare provider if you have any concerns or experience unexpected effects.
