Potential Side Effects and Risks of Using Viagra

Viagra, while effective for many, carries potential side effects. Headache is common, affecting approximately 16% of users. Facial flushing, a reddening of the skin, also occurs frequently.

Cardiovascular Risks

Viagra can lower blood pressure, potentially causing dizziness or lightheadedness. Individuals with pre-existing heart conditions should consult a doctor before use, as Viagra can increase the risk of heart attack or stroke. This risk is amplified in those with high blood pressure, angina, or other cardiovascular problems. Always disclose your medical history to your physician.

Visual Disturbances and Other Side Effects

Some users experience temporary visual changes, such as blurred vision or changes in color perception. Less common side effects include nasal congestion, indigestion, muscle aches, and back pain. Rarely, priapism (a prolonged, painful erection lasting more than four hours) can occur – this requires immediate medical attention.

Drug Interactions

Viagra interacts with certain medications, including nitrates (used to treat angina). Combining these can dangerously lower blood pressure. Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, to avoid potentially harmful interactions. This is crucial for safe use.

Who Should Avoid Viagra?

Men with certain medical conditions, like severe liver or kidney disease, should not use Viagra. Individuals with retinitis pigmentosa (a rare eye disease) are also advised against its use. Always consult a doctor to assess your suitability for Viagra.
