Who qualifies for Erectile Dysfunction medication

Our EU-licensed doctors carefully evaluate your medical history to ensure Erectile Dysfunction medication is safe and appropriate for you. They look for specific criteria and contraindications, including:

  • Heart Conditions: If you have a history of heart attack, stroke, angina, or irregular heart rhythms, the doctor will assess whether ED medication could strain your cardiovascular system.
  • Blood Pressure Issues: Both high and low blood pressure can be problematic. ED medications can lower blood pressure, which might be risky if you're already on blood pressure medication.
  • Liver or Kidney Problems: These organs process medication. Impaired function can lead to increased drug levels and higher risk of side effects.
  • Eye Conditions: Certain eye conditions, like retinitis pigmentosa, require caution, as vision changes can rarely occur.
  • Priapism Risk: If you've had a prolonged, painful erection (priapism) lasting over 4 hours, this must be disclosed.
  • Current Medications: A thorough review of all your current medications is crucial to identify potential dangerous drug interactions.

The doctor's priority is always your safety and well-being.

What Erectile Dysfunction medication actually does (and doesn't do)

Erectile Dysfunction medications like sildenafil (Viagra) and tadalafil (Cialis) work by increasing blood flow to the penis, helping you achieve and maintain an erection when you are sexually stimulated. They do not create sexual arousal; they enhance the physical response to it. For most men, these medications are highly effective, with effects typically seen within 30-60 minutes after taking them, lasting from a few hours to over a day depending on the specific medication.

It's important to have realistic expectations: these medications address the physical aspect of ED but don't resolve underlying psychological or relationship issues that might contribute to the condition.

Side effects and when to stop

Like all medications, Erectile Dysfunction drugs can cause side effects. Most are mild and temporary, but it's important to be aware of them:

  • Common Side Effects: Headache, flushing (redness of the face), nasal congestion, indigestion, and visual disturbances (e.g., blurred vision, sensitivity to light, changes in color vision) are frequently reported. These usually resolve on their own.
  • Serious Side Effects: Though rare, serious side effects require immediate medical attention. These include sudden vision loss, sudden hearing loss, priapism (a prolonged erection lasting more than 4 hours), and allergic reactions. If you experience any of these, stop taking the medication and seek emergency care.

Always discuss any concerns or unusual symptoms with your doctor immediately.
