Taking Viagra without a prescription carries significant risks. Side effects can range from mild to severe. Common ones include headaches, flushing, nasal congestion, and visual disturbances. More serious, though less frequent, side effects include prolonged erection (priapism), heart attack, stroke, and sudden hearing loss. These necessitate immediate medical attention.
Drug Interactions
Viagra interacts with numerous medications. Nitrates, often prescribed for chest pain, can cause a dangerous drop in blood pressure when combined with Viagra. This combination can be life-threatening. Similarly, alpha-blockers, commonly used to treat high blood pressure and enlarged prostate, increase the risk of low blood pressure. Other medications, including some antifungals and HIV medications, can also interact negatively with Viagra, potentially intensifying side effects or reducing its effectiveness. Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, before starting any new treatment.
Individual Risk Factors
Pre-existing conditions like heart disease, low blood pressure, and eye problems increase the risk of complications. Men with a history of stroke or heart attack should exercise extreme caution. Age also plays a role; older men may experience more pronounced side effects. If you have any health concerns, seek professional medical advice before considering Viagra, prescribed or otherwise.
