What is vardenafil?
Vardenafil is used for men with erection problems (erectile dysfunction). It works by increasing blood flow to the penis, to help achieve an erection. It will only work if you are sexually excited. Read more about erectile dysfunction.
In Aotearoa New Zealand vardenafil is available as tablets (10 mg and 20 mg).
- The dose can be either 10 mg or 20 mg. The dose depends on your response.
- Vardenafil is taken as a single dose before sexual activity. Do not take more than 1 dose a day.
- Always take your vardenafil exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much vardenafil to take, how often to take it and any special instructions.
How to take vardenafil
- Timing: Take your dose 25–60 minutes before you intend to have sex. Vardenafil can keep working for up to 5 hours.
- Swallow the tablet whole with a full glass of water. Do not take with grapefruit or orange juice.
- You can take it with or without food. It may take longer to work if you take it with a heavy meal. Avoid excessive alcohol as it can lessen the sexual response.
- Effectiveness: PDE5 inhibitors do not work for everyone – about a third of men don't see an improvement. Many men need to try the medication a few (6–8) times before it works. If you don't have any improvement, do not increase your dose. Instead talk to your doctor as there may be other treatment options.
How do I get vardenafil?
Vardenafil is available on prescription from your doctor. It is not funded in Aotearoa New Zealand for general erectile dysfunction. None of the PDE5 inhibitor medications are funded in New Zealand for general erectile dysfunction.
