Who qualifies for Sildenafil
Our EU-licensed doctors carefully assess each patient to determine if Sildenafil is a safe and effective treatment. They look for specific criteria, such as a confirmed diagnosis of pulmonary hypertension (PH) or erectile dysfunction (ED), and review your medical history for contraindications. For PH, Sildenafil is typically prescribed to relax blood vessels in the lungs, reducing pressure. Important factors considered include your current health status, other medications you are taking, and any pre-existing conditions like severe heart disease, liver or kidney impairment, or recent stroke/heart attack. The doctor ensures Sildenafil is appropriate before issuing a prescription.
What Sildenafil actually does (and doesn't do)
Sildenafil is a phosphodiesterase-5 (PDE5) inhibitor. It works by increasing blood flow to specific areas of the body. For pulmonary hypertension, Sildenafil relaxes the smooth muscle cells in the pulmonary arteries, which widens these blood vessels and reduces the high pressure in your lungs. This eases the strain on your heart and improves your breathing and exercise capacity. For erectile dysfunction, it helps achieve and maintain an erection by increasing blood flow to the penis when sexually stimulated. Sildenafil does not instantly create an erection or cure ED, nor does it affect sexual desire. Its effects for PH are noticeable over weeks, improving symptoms and quality of life.
Side effects and when to stop
Like all medications, Sildenafil can cause side effects. Common side effects include headache, flushing, nasal congestion, indigestion, and visual disturbances (e.g., blurred vision, blue-tinged vision). These are usually mild and temporary. More serious, but rare, side effects include a sudden decrease or loss of vision or hearing, or an erection lasting longer than four hours (priapism). If you experience any severe or persistent side effects, or if your condition worsens, discontinue use and seek immediate medical attention. Your doctor will provide full guidance on when to stop or adjust your dosage.
