Who qualifies for ED medication

Our EU-licensed doctors assess each patient individually to ensure safe and effective treatment. They look for specific criteria, including your overall health, medical history, and any existing conditions. Generally, ED medications like sildenafil (Viagra) and tadalafil (Cialis) are suitable for men experiencing difficulty achieving or maintaining an erection. However, certain health conditions, such as severe heart disease, uncontrolled high blood pressure, or a history of stroke, may be contraindications. The doctor will also consider medications you are currently taking, especially nitrates, which are incompatible with ED drugs. The online questionnaire helps the doctor understand your unique situation to determine if ED medication is appropriate and safe for you.

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

Most oral ED medications, such as sildenafil and tadalafil, are Phosphodiesterase-5 (PDE5) inhibitors. They work by increasing blood flow to the penis when you are sexually aroused. During sexual stimulation, your body releases nitric oxide, which leads to the relaxation of smooth muscles in the penis, allowing more blood to flow in. PDE5 inhibitors prevent the breakdown of a chemical called cGMP, which is crucial for this muscle relaxation and increased blood flow. This helps you achieve and maintain a firm erection. It's important to understand that these medications do not create sexual desire; they only assist with the physical process of erection when you are already stimulated. They typically start working within 30-60 minutes and their effects can last from 4 to 36 hours, depending on the specific medication.

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 temporary visual disturbances. More serious side effects are rare but can include a sudden decrease or loss of vision or hearing, or an erection lasting more than four hours (priapism). If you experience any severe or persistent side effects, you should stop taking the medication and seek immediate medical attention. Your Hi-Doctor will provide comprehensive information on potential side effects and interactions. Always follow your doctor's advice and report any unusual symptoms.
