Viagra, or sildenafil, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection during sexual stimulation. This improved blood flow results from Viagra’s inhibition of an enzyme called phosphodiesterase-5 (PDE5).

Who Can Use Viagra?

Men aged 18 and older diagnosed with ED by a healthcare professional can typically use Viagra. However, pre-existing health conditions, like heart problems or low blood pressure, may necessitate careful consideration and consultation with a doctor before starting treatment. Always discuss your medical history thoroughly with your physician.

Viagra’s Potential Side Effects

Common side effects include headache, facial flushing, nasal congestion, and indigestion. Less frequent, but more serious, side effects can include vision changes (blurred vision, blue tint) and hearing problems. Seek immediate medical attention if you experience any severe or persistent side effects.

Remember: Viagra does not provide spontaneous erections. Sexual stimulation is still required for it to be effective. Always follow your doctor’s instructions and prescribed dosage for safe and effective use.
