Vardenafil works by blocking the enzyme phosphodiesterase type-5 (PDE-5). This helps relax blood vessels and improves blood flow to the penis when you are sexually aroused.

Sexual stimulation is required for the medication to be effective.

For many men, vardenafil begins working within 30 to 60 minutes. The effects typically last up to 5 hours, although this can vary between individuals.

Vardenafil tablets are available in:

-5mg
-10mg
-20mg

Many men begin with the 10mg dose, which may be adjusted depending on effectiveness and tolerability. Your prescriber will determine the most appropriate strength based on your medical history and response.

Vardenafil may be suitable for adult men experiencing erectile dysfunction.

It may not be appropriate if you:

-Take nitrate medications
-Have certain heart conditions
-Have recently had a stroke or heart attack
-Have significant liver problems
-Are advised to avoid sexual activity

Suitability is assessed during your confidential online consultation.

Common side effects can include:

-Headache
-Indigestion
-Facial flushing
-Nasal congestion
-Dizziness or lightheadedness
-Blurred vision
-Palpitations

These are usually mild and temporary. Seek urgent medical attention if you experience chest pain, sudden vision loss, severe allergic reactions, or an erection lasting longer than four hours.
