What is vardenafil?

Vardenafil is an erectile dysfunction treatment which belongs to a class of drugs known as phosphodiesterase type 5 (PDE-5) inhibitors. It is the generic version of the brand name drug, Levitra and is commonly referred to as “generic Levitra”, or "generic vardenafil". The active ingredient is vardenafil hydrochloride (HCL). 

How does vardenafil work?

Vardenafil tablets work by increasing blood flow to the penis during sexual stimulation. The increase in blood flow can help to achieve and maintain an erection. Vardenafil will only work if there is sexual stimulation and will not increase sexual desire. PDE5 inhibitors may not always work the first time you take them. You should keep an open mind and try treatment on several occasions before deciding whether to increase the dose or try an alternative medication. You should speak to your doctor or pharmacist if you find that treatment is not effective.

How long does it take for vardenafil to work?

Vardenafil tablets usually take around 25 to 60 minutes to work. For vardenafil to work quicker, you should take it on an empty stomach. Taking a tablet after a heavy meal will mean that it will take longer for the effects to kick in.

How long does vardenafil last for?

The effects of vardenafil last for around 4-5 hours on average. This can vary slightly and factors such as body weight and frame of mind can influence the length of time that vardenafil is effective for.

Vardenafil dosage instructions

Take one tablet around 30 to 60 minutes before sexual activity. Swallow the tablet whole with a glass of water. If you are sexually stimulated, you may achieve an erection anywhere between 30 minutes to 4 hours after having taken a tablet. If you are trying vardenafil for the first time, you should start off with the 10mg dose.

Vardenafil is available in 3 different strengths:

Vardenafil 5mg tablets 

Vardenafil 5mg is the recommended dosage for men over the age of 60 or those who have experienced side effects with higher doses of vardenafil or other ED treatments.

Vardenafil 10mg tablets 

Vardenafil 10mg is the recommended dose for men who are taking vardenafil for the first time.

Vardenafil 20mg tablets 

Vardenafil 20mg is the recommended dose if 10mg has been unsuccessful.

You should not take more than one tablet within a 24-hour period.

Vardenafil vs Viagra (sildenafil) – What is the difference?

  • Vardenafil tablets are more potent than sildenafil tablets, therefore, a lower dose is required.
  • Vardenafil acts slightly quicker than sildenafil, taking around 25-60 minutes to work, as opposed to sildenafil, which takes 60 minutes.
  • Vardenafil lasts for up to 5 hours, whilst sildenafil lasts for up to 4 hours.
  • Vardenafil is not affected by food, however, sildenafil is more effective on an empty stomach. 
  • Regarding effectiveness, clinical trials report similar results. In theory, this means that they are both as good as each other. 
  • Sildenafil has the price advantage, as it is cheaper than vardenafil. 
  • Viagra is not better than vardenafil and vice versa. Individuals may respond differently to alternative treatments. What works for you, may not work for someone else. 


Vardenafil vs Cialis (tadalafil) – What is the difference?

  • Tadalafil tablets work slightly quicker than vardenafil tablets, taking around 30 minutes to become active.
  • Tadalafil has a longer window of action, lasting for up to 36 hours.
  • Vardenafil needs to be taken before sex, which means that you need to schedule doses. Tadalafil offers the option of a daily tablet, known as tadalafil daily, which can be taken every day, providing a continuous effect. This avoids the need to schedule doses.
  • Both drugs appear to have similar results in clinical trials.
  • The side effect profile of both treatments are similar. 
  • Tadalafil has the price advantage, as it is cheaper than vardenafil. 

Individuals who have trialled ED treatments will often have their own preference. What works for one person, may not work for another and vice versa. To the same degree, you may experience side effects with one type of treatment, and not the other.
