What is vardenafil?

Vardenafil is a treatment for erectile dysfunction (ED). It is a type of medicine known as a phosphodiesterase type 5 inhibitor (PDE-5 inhibitor) and works by increasing blood flow to the penis when a man is sexually stimulated. Vardenafil does not increase sexual desire but helps him to achieve and maintain an erection for longer when he is sexually stimulated. This can help men who suffer from ED maintain an erection long enough for sexual activity to take place.

How long does vardenafil last?

Vardenafil’s effects typically last for 4–5 hours.

How long does vardenafil take to work?

Vardenafil usually takes around 25 minutes to become effective, however, in clinical studies, a third of patients achieved a satisfactory erection within just 15 minutes of taking vardenafil. For the best results, it should be taken between 25 and 60 minutes before sexual activity. The onset of effects may be delayed if it’s taken alongside a high-fat meal.

How effective is vardenafil?

Vardenafil is an effective treatment for erectile dysfunction in 66–80% of patients. If Vardenafil does not seem to be an effective treatment for you, you can speak to a doctor about alternative options.

Vardenafil and psychological ED

The root cause of erectile dysfunction is often psychological and the condition is often exacerbated by the stress and anxiety associated with not being able to perform sexually. Vardenafil is an effective, short-term solution that can help relieve some of the worry, which in term may help you to relax and become more confident during sex. However, it is important to be aware that vardenafil can mask the root cause of the problem, and you should speak to a doctor about getting some psychological help if you think you might need it.

When is vardenafil most effective?

Vardenafil can remain effective for up to 5 hours after administration. For best results, it should be taken between 25 and 60 minutes before engaging in sexual activity.

Starting vardenafil

Always start taking vardenafil as instructed by a doctor or pharmacist. To begin with, a doctor will usually recommend a dose of 10mg taken no more than once daily. Check in with your doctor once you’ve started taking vardenafil, and they can discuss the possibility of increasing or decreasing your dosage if necessary.

How to take vardenafil

Swallow one vardenafil tablet whole with water, around 25 to 60 minutes before sexual activity. Do not take more than your prescribed dose, or take more than one tablet per day, as taking too much vardenafil can increase the risk of side effects.

How to get an erection whilst taking vardenafil

When taking vardenafil, you should try to enjoy sexual activity as normal. If taken 25 to 60 minutes before sexual activity, vardenafil will help you to achieve an erection when you are aroused.

Vardenafil dosage

The recommended dosage of vardenafil is 1 x 10mg tablet taken around 25 to 60 minutes before engaging in sexual activity, no more than once per day. Your doctor may choose to reduce your dose to 5mg, or increase it to 20mg if necessary. You should not adjust your dose without first speaking to a doctor.

Treatment Options

What if vardenafil doesn’t work for me?

If vardenafil does not work for you, speak to your doctor for advice on other treatments. Different erectile dysfunction treatments are more effective in different people, and you may need to try a few to find the best fit for you.

Are vardenafil and Viagra the same?

Vardenafil and Viagra (sildenafil) are different medicines, but they both belong to the same drug class (PDE-5 inhibitors) and work in very similar ways. Both can stay effective in the body for up to 5 hours.

What is generic Levitra?

Levitra is the brand name for the generic drug vardenafil. Both contain the active ingredient vardenafil and work in the same way, although vardenafil can be cheaper. Generic vardenafil became available to purchase in the UK in October 2018, but should only be purchased from a registered pharmacy or online pharmacy, such as Dr Felix, as unlicensed versions exist and can be dangerous

Lifestyle changes to improve erectile dysfunction

If you suffer from erectile dysfunction, you can try making some lifestyle changes to help. The root cause of ED is often psychological, with stress and anxiety being major triggers. Where possible, try to reduce the impact of stress in your life by spending sociable time with friends and family, exercising regularly and practising relaxation techniques. Cutting down on alcohol and quitting smoking can also have an impact, improving your general health and well being and helping you to feel more energised. Anxiety can be further exacerbated by problems with sexual performance. Try speaking to your partner about your worries, and be open and honest about sex and sexual anxiety.

Vardenafil vs. orodispersible vardenafil

Vardenafil can be purchased in the form of film-coated tablets which are swallowed, or in the form of orodispersible tablets which dissolve in the mouth (sold under the name Levitra orodispersible). The tablets are available at a dose of 5, 10 and 20mg, whereas the orodispersible tablets are only available as 10mg. If you are taking the orodispersible tablets but need a higher or lower dose, you may need to switch to capsules.

Vardenafil vs other erectile dysfunction medications

You may need to try a few different erectile dysfunction treatments before finding the one which is right for you, and a doctor will be able to give you advice. Some people experience side effects of one treatment but have no problem with others. Vardenafil, tadalafil (Cialis) sildenafil (Viagra) and avanafil (Spedra) are similar medications that work by increasing blood flow to the penis when combined with sexual arousal. It can take a while to find which medication works best for you, but some of the key differences to consider are listed below:

  • Spedra is fast-acting, working in as little as 15 minutes. This makes it very helpful for men who want to have more spontaneous sex. However, Spedra is a bit more expensive as it is still under patent. 
  • Viagra Connect is available over the counter. Some men find this a more convenient option if the 50mg dose works for them. 
  • There is the option to take tadalafil (Cialis) as a low daily dose. This can suit men who want to have more spontaneous or more frequent sex. 
  • Levitra is available in an orodispersible form, which can help men who have difficulty swallowing tablets.


Can vardenafil be bought over the counter?

Vardenafil is a prescription-only medicine in the UK and cannot be legally purchased over the counter. The only ED medication available over the counter in the UK is 50mg tablets of Viagra Connect.

Will vardenafil give me an erection for hours?

While Vardenafil can remain effective in the system for up to 5 hours, it only works in combination with sexual stimulation. It will only help to maintain and achieve an erection when engaging in sexual activity, and will not give you an erection for hours.

Can women take vardenafil?

Vardenafil is a treatment for erectile dysfunction and should be taken by men only. Do not take this medication if you are female.

Does vardenafil increase libido?

Vardenafil will not increase your libido or cause you to become sexually stimulated. It only works in combination with sexual stimulation, when it increases blood flow to the penis and helps a man to achieve and maintain an erection.
