Generic Viagra, like its brand-name counterpart, can cause side effects. The most common include headache, flushing, nasal congestion, and upset stomach. These are usually mild and temporary.
More serious, though less frequent, side effects include vision changes (blurred vision, blue-tinted vision), prolonged erection (priapism), and hearing loss. Seek immediate medical attention if you experience any of these.
Certain medications interact with Viagra. Nitrates, often prescribed for heart conditions, are a particularly dangerous combination. This combination can cause a significant drop in blood pressure, leading to serious health problems. Always inform your doctor of all medications you are taking, including over-the-counter drugs and supplements, before starting Viagra.
Alpha-blockers, used to treat high blood pressure and enlarged prostate, can also interact with Viagra, potentially causing dizziness or low blood pressure. Your doctor may need to adjust your dosages.
Grapefruit juice can increase Viagra’s concentration in your bloodstream, potentially intensifying its effects and side effects. Avoid grapefruit juice while taking Viagra.
