Who qualifies for ED medication

EU-licensed doctors review each case individually to ensure ED medication is safe and appropriate for you. They look for specific criteria, including your medical history and current health status. Generally, men experiencing consistent difficulty achieving or maintaining an erection suitable for satisfactory sexual activity may qualify. However, certain contraindications exist, such as severe heart conditions, uncontrolled high blood pressure, recent stroke or heart attack, and specific eye conditions. The doctor will assess all these factors based on your questionnaire responses.

What ED medication actually does (and doesn't do)

Most common ED medications, like sildenafil (Viagra) and tadalafil (Cialis), are PDE5 inhibitors. They work by relaxing the smooth muscles in the penis and increasing blood flow, which helps you achieve and maintain an erection when sexually stimulated. They do not increase libido or cause an instant erection without sexual arousal. Expect the medication to work within 30-60 minutes, with effects lasting from 4 to 36 hours depending on the specific drug. These medications help you perform, but they don't cure ED; they manage its symptoms.

Side effects and when to stop

Like all medications, ED treatments can cause side effects. Most are mild and temporary:

• Headache: A common side effect, usually mild.
• Flushing: A feeling of warmth or redness in your face, neck, or chest.
• Nasal Congestion: A stuffy or runny nose.
• Indigestion: Heartburn or stomach discomfort.
• Visual Disturbances: Temporary blurred vision or a bluish tinge (more common with sildenafil).
• Muscle Aches: Especially in the back or legs (more common with tadalafil).

These usually subside as your body adjusts. However, some side effects require immediate medical attention:

• Priapism: An erection lasting more than 4 hours. This is a medical emergency.
• Sudden Vision Loss: In one or both eyes.
• Sudden Hearing Loss: Sometimes with ringing in the ears or dizziness.
• Allergic Reaction: Rash, itching, swelling, severe dizziness, or difficulty breathing.
• Chest Pain: Or other heart-related symptoms.

If you experience any serious side effects, stop taking the medication and seek emergency medical care immediately. Your Hi-Doctor.ai prescribing doctor is available for private chat if you have concerns.
