Who qualifies for ED medication

Our EU-licensed doctors carefully assess each patient to ensure ED medication is safe and appropriate. Here's what the doctor looks for in your case:

• Your medical history: We need a full picture of your health, including any existing heart conditions, blood pressure issues, or liver/kidney problems.
• Current medications: It is crucial to disclose all medications you are currently taking, including over-the-counter drugs, supplements, and herbal remedies. This helps us identify potential drug interactions.
• Allergies: Any known allergies to ED medications or their components.
• Overall health: A general assessment of your physical health helps determine suitability for treatment.

Certain conditions or medications may contraindicate the use of ED drugs. The doctor will discuss these with you if they arise during your consultation, ensuring your safety is always the priority.

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

ED medications like sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Spedra) are phosphodiesterase-5 (PDE5) inhibitors. They work by increasing blood flow to the penis when you are sexually stimulated, which helps you achieve and maintain an erection. They do not cause an erection automatically; sexual arousal is still necessary.

These medications are effective for most men with ED, but they are not a cure. They treat the symptoms of ED, allowing for satisfactory sexual activity. It's important to have realistic expectations. They don't increase libido or protect against sexually transmitted infections.

Side effects and when to stop

Like all medications, ED drugs can have side effects. Common side effects include headache, flushing, nasal congestion, indigestion, and dizziness. Less common but more serious side effects can include sudden vision loss, hearing loss, or an erection that lasts longer than four hours (priapism). If you experience any severe or persistent side effects, you should stop taking the medication and seek immediate medical attention.

Our doctors will discuss potential side effects with you during your consultation and advise on when to seek help. Medical honesty from your side builds trust and ensures your safety.
