Viagra, while effective for many, carries potential side effects. Headache is common, affecting up to 16% of users. Facial flushing, nasal congestion, and indigestion also occur frequently. Less common, but still possible, are visual disturbances like blurred vision or changes in color perception. These usually are mild and temporary.
Cardiovascular Risks
More serious, though rare, are cardiovascular issues. Viagra can lower blood pressure, posing a risk for individuals with pre-existing heart conditions. Chest pain, irregular heartbeat, and even heart attack are possibilities, particularly in those with underlying cardiovascular disease. Consult your doctor before using Viagra if you have heart problems or high blood pressure.
Other Potential Side Effects
Prolonged erection (priapism) is a serious side effect requiring immediate medical attention. This painful condition can lead to permanent erectile dysfunction if untreated. Dizziness and fainting are other less frequent side effects to be aware of. Some men report hearing loss or tinnitus. Rarely, Viagra can cause vision loss. This usually involves non-arteritic anterior ischemic optic neuropathy (NAION), a condition that can lead to blindness. Seek immediate medical help if you experience any sudden vision changes.
Medication Interactions
Viagra interacts with certain medications, including nitrates used to treat angina. This combination can drastically lower blood pressure, potentially leading to a life-threatening situation. Always inform your doctor about all medications, supplements, and herbal remedies you are taking before starting Viagra.
