Buy vardenafil tablets 

You can buy vardenafil as long as it's been approved and prescribed by one of our clinicians.  

While not a household name like Viagra, vardenafil is an effective treatment for erectile dysfunction available in 5mg, 10mg and 20mg doses.  

 

How vardenafil works 

Vardenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. They work by helping to more blood to flow to your penis, helping you get and maintain an erection. 

However, like with all erection pills, you won't immediately get hard by taking a tablet. You need to be sexually aroused for vardenafil to work.  

How long does vardenafil take to work? 

After you’ve taken vardenafil, it normally starts to work within 25-60 minutes. With that in mind, you should take vardenafil around an hour before you want to have sex.  

How long does vardenafil last? 

Vardenafil typically stays in your system for 4-5 hours, roughly the same amount of time Viagra lasts. If you want a longer-lasting alternative, then tadalafil lasts up to 36 hours.  

What’s the difference between vardenafil and Levitra? 

Vardenafil is the generic version of the brand-name drug Levitra. Both work in exactly the same way and last the same length of time. The only real difference is that, because it’s a generic drug, vardenafil is typically cheaper.  

 

How effective is vardenafil? 

A 2005 study found that vardenafil 10mg helped 74% of men maintain an erection, and 87% of men complete success penetration during sex.  

 

Vardenafil dosages 

Chemist4U offers three doses of vardenafil: 5mg, 10mg and 20mg.  

  • Vardenafil 5mg: you may be prescribed 5mg of vardenafil if you struggle with the side effects of the 10mg tablet.

  • Vardenafil 10mg: this is the recommended starting dose and should be taken no more than once a day.

  • Vardenafil 20mg: you might be able to up your dosage to 20mg if you’ve tolerated the side effects of the 10mg tablet but haven’t had the desired effects when it comes to your erection.

 

How to take vardenafil safely 

  1. Swallow one tablet whole, with a glass of water. 

  1. Take around an hour before you want to have sex. 

  1. Do not take vardenafil more than once a day.  

You should always read the patient information leaflet before taking vardenafil.  

 

Vardenafil side effects

Certain studies have shown that vardenafil may cause fewer side effects than other erectile dysfunction pills. Vardenafil is more selective in how it works when treating erectile dysfunction, resulting in fewer side effects.  

However, you made still experience side effects when taking vardenafil, including: 

  • headache

  • dizziness

  • flushing

  • a blocked or runny nose

  • indigestion

For a complete list of side effects, please read the patient information leaflet. If you experience any side effects not included in the patient information leaflet, you can report them using the MHRA Yellow Card Scheme.
