Viagra, containing sildenafil citrate, primarily treats erectile dysfunction (ED), a condition impacting a man’s ability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. It works by increasing blood flow to the penis, facilitating an erection in response to sexual stimulation. This effect is achieved by inhibiting an enzyme called phosphodiesterase-5 (PDE5).
Who Should Use Viagra?
Men diagnosed with ED by a healthcare professional should consider Viagra. However, it’s not suitable for everyone. Pre-existing heart conditions, low blood pressure, or use of certain medications (like nitrates) necessitate a discussion with a doctor before starting Viagra. Also, men with certain eye conditions or liver/kidney problems might need alternative treatments.
Understanding Potential Side Effects
Common side effects include headache, flushing, nasal congestion, and visual disturbances. Less frequent but serious side effects include prolonged erections (priapism) and sudden vision or hearing loss. Seek immediate medical attention if you experience these.
