Who qualifies for Sildenafil
When you consult with a Hi-Doctor EU-licensed physician, they carefully evaluate your medical history and current health status to determine if Sildenafil is right for you. They look for specific criteria to ensure your safety and the effectiveness of the treatment. Generally, Sildenafil is prescribed for adult men experiencing erectile dysfunction (ED). However, certain conditions may prevent its use, including severe heart conditions, recent stroke or heart attack, low blood pressure, and specific eye diseases. The doctor also assesses existing medications, as Sildenafil can interact dangerously with nitrates and some alpha-blockers. Your medical questionnaire helps the doctor understand your individual case, ensuring a personalized and safe treatment plan.
What Sildenafil actually does (and doesn't do)
Sildenafil, commonly known by its brand name Viagra, belongs to a class of medications called PDE5 inhibitors. It works by increasing blood flow to the penis, which helps you achieve and maintain an erection when you are sexually aroused. It does not cause an erection on its own; sexual stimulation is still required. Sildenafil typically starts working within 30 to 60 minutes after taking it, and its effects can last for up to 4 hours. It is important to understand that Sildenafil treats the symptoms of ED, but it does not cure the underlying cause. It also does not protect against sexually transmitted infections.
Side effects and when to stop
Like all medications, Sildenafil can cause side effects. Common side effects are generally mild and temporary, and may include headache, flushing (redness or warmth in your face, neck, or chest), nasal congestion, indigestion, and temporary changes in vision (such as blurred vision or a bluish tinge). More serious, but rare, side effects include sudden vision loss, sudden hearing loss, or an erection lasting longer than 4 hours (priapism). If you experience any of these severe side effects, seek immediate medical attention. Always inform your doctor about any side effects you experience, and if they are bothersome or persistent, the doctor may advise adjusting your dosage or discontinuing the medication.
