Viagra, or sildenafil citrate, treats erectile dysfunction (ED) by increasing blood flow to the penis. This allows for firmer, longer-lasting erections sufficient for sexual intercourse. It’s crucial to remember Viagra only works with sexual stimulation; it doesn’t create spontaneous erections.
Common Side Effects
While generally safe, Viagra can cause side effects. Headaches are quite common, alongside facial flushing and nasal congestion. Less frequent, but still possible, are indigestion, visual disturbances (like blurry vision or sensitivity to light), and back pain. Serious side effects are rare but include prolonged erections (priapism) requiring immediate medical attention. Discuss any concerns with your doctor before use.
Important Considerations
Viagra interacts with certain medications, particularly nitrates used for heart conditions. Combining them can dangerously lower blood pressure. Pre-existing heart problems, stroke history, or uncontrolled high blood pressure also necessitate careful consideration and consultation with a physician before taking Viagra. Men with liver or kidney disease should also discuss its use with their doctor. The recommended dosage is typically 50mg, but your doctor may adjust this depending on your individual needs and health status. Always follow your doctor’s instructions precisely.
