Can I buy Vardenafil online?
Vardenafil is a prescription-only medication, which means it can only be legally prescribed and sold online by services such as Superdrug Online Doctor.
If you are going to buy Vardenafil online, you should make sure that the seller is registered with the Care Quality Commission (CQC) and the Medicines and Healthcare Products Regulatory Agency (MHRA).
If you’re not sure if a company is registered with either the CQC or the MHRA, then they may be operating illegally, selling fake medicines, or prescribing incorrectly.
Vardenafil is:
- a treatment for erectile dysfunction
- the generic version of Levitra, and works in the same way
- effective for around 70% of men
How does Vardenafil work?
Vardenafil relaxes the blood vessels and muscles around your penis to increase blood flow. The increase in blood helps you to get and keep an erection as long as you’re sexually aroused.
How long does Vardenafil last?
The effects of Vardenafil usually last up to 4 hours but some men may experience the effects for up to 6. This is like other types of erectile dysfunction treatments like Viagra.
How to take Vardenafil
You should take Vardenafil exactly how your doctor has told you to.
- Take Vardenafil around an hour before you intend to have sex
- Swallow one tablet whole with a glass of water
- Avoid eating heavy meals or drinking alcohol before taking it, as doing this can reduce its effectiveness and make it take longer to work
- You should only take one tablet in a 24-hour period, taking more can cause serious side effects.
- Do not take Vardenafil with any other erectile dysfunction medication.
What strengths is Vardenafil available in?
Vardenafil is available in a few different dosages – 5mg, 10mg and 20mg. You should never increase your dose without a doctor’s advice. If you feel the effects of Vardenafil are too strong or too weak for you, consult your doctor for advice.
Vardenafil 5mg
The 5mg doses of Vardenafil are the lowest available and are usually prescribed to men who have experienced side effects on the higher doses.
These dosages of Vardenafil are also suitable for men who are taking other medications or have health problems which make taking the higher doses unsafe. The lower doses also reduce the risk of drug interactions and side effects.
Vardenafil 10mg
The 10mg dose of Vardenafil is usually what you are prescribed if you are taking Vardenafil for the first time. If you have a liver issue, you may be prescribed an even lower dose to begin with.
If you take 10mg and feel you need a higher or lower dose, your doctor will be able to discuss this with you.
Vardenafil 20mg
The maximum dose of Vardenafil available is 20mg. This dose is normally given to you if you’ve tried 10mg,it didn’t work, and you didn’t experience any side effects.
If you take over 20mg of Vardenafil then you are at risk of side effects and complications. If you try 20mg and find it doesn’t work, there are other ED treatments you could try.
As with other medications, Vardenafil can cause side effects. Most men do not encounter any serious problems when taking it.

this item did not work for me.
-
Product certainly works, i purchased the 20mg tabs because it was more economical to buy and then cut in half! My first attempt, the cut probably left a split of 40/60, i took the smaller portion as apprehensive, no side affects to report. i have never used these type of products before. Will report back when i have used the other larger half of the tablet. I booked the tablets online from super drug for pick up from a local store, after an online assessment , highly nervous, i picked them up, and can say the service was very discrete and would be happy to use again.
