Vardenafil
from 
Vardenafil is the active ingredient in the erectile dysfunction medication Levitra. In some countries, it is sold under the brand names Vivanza or Staxyn. Vardenafil is a substance known as a pde5 inhibitor and it belongs to the same group of medicines as Viagra. Like other erectile dysfunction drugs, it increases the blood flow to the penis and makes it easier to get and keep an erection. Its effect lasts for about four to five hours. While taking vardenafil, you only get an erection with sexual stimulation.

Generic Levitra
There is no generic version of levitra licensed for sale in the UK. If you want to take vardenafil, you need to get a prescription for Levitra.
Vardenafil takes time to work and you need to take it 25 minutes to an hour before you want to have sex. How quickly it takes effect differs between men and it also depends on whether you have it with a meal or not. If you take it with food, you may find that it takes longer to work.
Swallow the tablet whole with a drink of water. You mustn't take more than one tablet per day and you mustn’t exceed the dosage you have been prescribed. If you find the effects of the medication too strong or too weak, ask your doctor to recommend a different dosage or an alternative medication.
You should bear in mind that drinking alcohol decreases your ability to have an erection. In order to get the best effect from your treatment, you should avoid drinking alcohol.
Vardenafil tablets are available in different dosages. The most commonly prescribed dosage is 10mg. If you have never taken vardenafil before, your doctor will most likely recommend that you try this dose first. Most men find that a 10mg dose is sufficient to help them get and maintain an erection.
If you find the effect of the 10mg tablet is too weak, you can ask your doctor whether the 20mg tablets may be suitable for you.
Vardenafil is sometimes prescribed in lower dosages of 2.5mg and 5mg. This can be necessary in patients who suffer from particular conditions, such as liver problems.
Do not take more vardenafil than is prescribed.
As other medications used to treat erection problems in men, vardenafil can cause side effects. Most men do not encounter any serious problems when taking the drug.
