Vardenafil is a medication used to treat erectile dysfunction (ED) in men over the age of 18.
Vardenafil is commonly found as a branded tablet known as Levitra. This is the same medication.
Vardenafil is a phosphodiesterase type 5 inhibitor that can help you to get and keep an erection. It works by reducing the action of a natural chemical in your body that can prevent you from getting an erection. This helps improve blood flow to your penis, making getting an erection easier.
Vardenafil should be taken around 25 minutes to an hour before sex and can last around 4 to 5 hours.
How does vardenafil work?
Vardenafil contains the active ingredient vardenafil, which is a phosphodiesterase type 5 inhibitor. It works by reducing the action of a natural chemical inside your body which can make erections go away. This helps you to keep an erection for longer.
How to take vardenafil
- Take 1 tablet of vardenafil 25 to 60 minutes before sex
- Swallow the tablet whole with a glass of water
- You must be sexually aroused for vardenafil to work
You should always take vardenafil as prescribed and never take more than your doctor has told you to.
Vardenafil can be taken with or without food but avoid high fat or heavy meals as this can delay the effect of the medication. Avoid drinking alcohol as this can make it harder to get and keep an erection. You should also avoid drinking grapefruit juice as this may prevent vardenafil from working as it should.
Do not take vardenafil more than once a day.
How long does it take for vardenafil to work?
Vardenafil usually takes between 25 to 60 minutes to take effect. If you have taken vardenafil after eating a large or high fat meal, it may take a little longer for vardenafil to take effect. This is because your body is also digesting food as well as your medication.
If vardenafil does not work the first time, you should wait until the next time you want to have sex and try again. Make sure this is not on the same day as you cannot take 2 tablets in one day. Your doctor will recommend trying vardenafil on 8 separate occasions before considering a higher dose or changing ED treatment.
How often can you take vardenafil?
You can take vardenafil once per day, which means you should wait 24 hours between doses. If you take more than one tablet in a day, you are more likely to get side effects. Speak to your doctor if you take more vardenafil than you should.
How long does vardenafil last?
Vardenafil usually lasts between 4 and 5 hours, but this can be different for every man.
Vardenafil is available in 3 doses: 5mg, 10mg, and 20mg. The usual starting dose of vardenafil is one 10mg tablet, to be taken no more than once a day. This is to see how your body reacts to the medication and how effective it is for you. If you have tried using vardenafil 8 separate times and it is not working for you or your erections are not lasting as long as you would like, speak to your doctor. They may recommend a higher dose or a different treatment. The highest dose of vardenafil that can be prescribed is 20mg. If you get side effects, but Vardenafil is working for you, your doctor may recommend a lower dose to see if you get the desired effects, but reduced side effects.
Who can use vardenafil?
You can use vardenafil if you are over 18 and diagnosed with erectile dysfunction by a doctor. You must also have a prescription for the medication, as it could potentially be unsafe for you if you don’t.

- a physical condition that affects the shape of your penis
- a heart problem, as it could be dangerous for you to have sex

Vardenafil vs Viagra
While vardenafil and Viagra have different active ingredients, they are both a type of medication called a phosphodiesterase type 5 inhibitor and do still work in the same way. Viagra is a branded medication and vardenafil is a generic medication, this means Viagra is sold under a brand name whereas vardenafil is not, making it more likely to be cheaper or prescribed on the NHS.
Both vardenafil and Viagra need to be taken about 30-60 minutes before sex, and both last up to 4-6 hours. There is a slight difference in how effective each medication is with studies showing Viagra to be 74% effective for men who use it and Levitra 54-74% effective. How effective these medications are varies from person to person, so while Viagra may be the right treatment for you, Levitra may be more effective for someone else. Your doctor will help you find the right and most suitable ED treatment for your needs.
