Who qualifies for Sildenafil or Tadalafil
When you complete your medical questionnaire, an EU-licensed doctor assesses your health profile to determine if Sildenafil or Tadalafil is a safe and appropriate treatment for you. Doctors look for specific criteria, including your medical history, current medications, and overall health. Generally, you must be an adult male experiencing ED. Certain conditions, such as severe heart problems, recent stroke or heart attack, low blood pressure, or specific eye conditions, may contraindicate the use of these medications. Your doctor will ensure that the treatment aligns with your health needs and poses no significant risks.
What Sildenafil and Tadalafil actually do (and doesn't do)
Both Sildenafil (Viagra) and Tadalafil (Cialis) are PDE5 inhibitors. They work by increasing blood flow to the penis during sexual stimulation, helping you achieve and maintain an erection. They do not cause an erection on their own; sexual stimulation is still required. Sildenafil typically works within 30-60 minutes and lasts for about 4-6 hours. Tadalafil has a longer duration, lasting up to 36 hours, offering more spontaneity. Neither medication cures ED, but they effectively manage its symptoms. They do not increase sex drive or protect against sexually transmitted infections.
Side effects and when to stop
Like all medications, Sildenafil and Tadalafil can cause side effects. Common side effects include headache, flushing, nasal congestion, and indigestion. Sildenafil can sometimes cause temporary visual disturbances. Tadalafil may lead to back pain or muscle aches due to its longer half-life. 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 severe or prolonged side effects, stop the medication immediately and seek urgent medical attention. Your doctor will discuss all potential risks with you before prescribing.
