Product information

Vardenafil tablets are a prescription drug used in erectile dysfunction. It is the generic version of the Bayer drug, Levitra. The patent on this treatment expired in October 2018, enabling other manufacturers to produce Vardenafil as a generic medicine. It works by easing pressure in blood vessels, and facilitating better blood flow to the penis. Vardenafil is available to buy online from our UK pharmacy in three different doses: 5mg, 10mg and 20mg.

How does generic Levitra work? 

Vardenafil is a type of medicine called a PDE5 inhibitor. The treatment was originally developed by Bayer and released in 2003 under the name Levitra. Bayer’s sole rights to produce Vardenafil under this name expired in October 2018. Vardenafil is therefore now available to buy online as a generic medicine.

PDE5 inhibitors work by helping to widen constricted blood vessels at the base of the penis. Symptoms of ED are often caused by a lack of blood flow to the penis, due to these blood vessels becoming taut, and not letting sufficient blood through to obtain an erection. By enabling blood to pass more freely into the penis, Vardenafil helps the user to get and sustain an erection more easily.

Why should I choose Vardenafil? 

Vardenafil offers an alternative to other ED treatments such as Viagra or Cialis. It is a safe and reliable treatment that is taken 30-60 minutes before sexual intercourse and can last up to four or five hours. Like other PDE5 inhibitors, it still requires sexual stimulation in order to work.

How do I select my dosage? 

The strength of the Vardenafil dose you require will depend on your past experience with ED treatments. 

Taking Vardenafil 5mg or 10mg

If you have not used Vardenafil before your doctor will most likely recommend a 5mg starting dose. However, if 5mg has been found to be insufficient then your doctor may prescribe the 10mg dose. 

Taking Vardenafil 20mg

The 20mg dose is usually reserved for men when use of the lower doses has not worked. It is important that the Vardenafil 20mg dose is only taken when your doctor prescribes it. 

What is ED?

Erectile dysfunction is a characterised by an inability to achieve or sustain an erection firm enough for sexual intercourse. It’s a common problem, thought to affect at least half of men over the age of 40; however, many younger men experience the condition too. Often the issue can resolve on its own after a short time, but in cases where symptoms persist, treatment may be able to help.

What causes erection problems?

There are several possible causes of erectile dysfunction (known also as impotence or ED). Psychological or emotional factors can often play a part, such as pressure to perform in a new relationship, feelings of stress or worry (which may not necessarily be connected to the act of sex itself), or depression. Lifestyle habits, for example smoking, alcohol consumption and not getting enough exercise, can induce symptoms as well.

In some cases, a health condition like high blood pressure, high cholesterol or diabetes or may be the root cause. So, if you develop erectile dysfunction and find that symptoms persist, it’s a good idea to see a doctor about the issue, so that they can rule out any underlying condition that may be behind it.

When treating ED, a doctor may suggest making lifestyle changes to help tackle symptoms. This might include cutting down on alcohol intake, quitting smoking, or exercising more. However in some instances, these measures may not be enough, and prescription treatment may be necessary.

Can I order Vardenafil online? 

Yes. Our service provides a secure remote consultation service, where your order goes to a GMC-registered doctor or UK pharmacy prescriber to be reviewed, before a prescription is issued. Approved orders are dispensed at our UK-based pharmacy, before being shipped in secure packaging by tracked delivery. We use next-day courier services, so in most cases you’ll receive your medicine in one working day.

Page last reviewed:  26/04/2022

Read the instructions in the patient information leaflet carefully, and always follow the directions issued by your prescriber when using this treatment.

  1. The typical dose is one tablet, taken as required, ideally 30 minutes before intercourse.
  2. Swallow your tablet whole with a glass of water.
  3. It should take between 25 and 60 minutes for Vardenafil to have an effect.
  4. Taking Vardenafil with or just after a large meal may slow down the metabolism of the drug in the body, meaning it takes longer to work.
  5. The drug remains active in the body for up to five hours after administration.
  6. Do not exceed the prescribed dose.
  7. Never take more than one tablet in any 24 hour period.
  8. If you experience a persistent erection that lasts for four hours or more, you should seek urgent medical advice.
  9. Vardenafil requires sexual stimulation to work.

If you are unsure of anything relating to this medication, ask your doctor or pharmacist for help before taking it.

Taking it with other medications

Do not use any other treatment for ED at the same time as Vardenafil.

Tell your doctor about any other medications you are using. This is particularly important if you are using the following, as they may cause interactions with this treatment: nitrates, medicines for angina, or nitric oxide donors, such as amyl nitrite; arrhythmia medicines, such as quinidine, procainamide, amiodarone or sotalol; medicines for HIV, such as ritonavir or indinavir; antifungal medicines such as ketoconazole or itraconazole; macrolide antibiotics such as erythromycin or clarithromycin; alpha-blockers; medicines for enlarged prostate; or riociguat.

Conditions to look out for

Inform your prescriber of any medical conditions you have during consultation. You must not use Vardenafil if you: are allergic to anything in it; are over 75 and taking antifungal treatment; have a severe heart or liver problem; are having kidney dialysis; have recently had a stroke or heart attack; have or have had low blood pressure; have a history of degenerative eye diseases in your family; or have ever had non-arteritic ischemic optic neuropathy (NAION).

You may be advised not to take this medicine, or take it with caution, if you: have heart trouble; have an irregular heartbeat, have an inherited heart disease; have a physical condition affecting the shape of the penis; have an illness that can cause erections which won’t go away, such as sickle cell disease, multiple myeloma and leukaemia; have a stomach ulcer; or have a bleeding disorder.

Alcohol and grapefruit juice

Drinking excessive amounts of alcohol can exacerbate erectile dysfunction and affect how well the treatment works.

Grapefruit juice can affect the activity of vardenafil in the body, and make side effects more likely. You should therefore avoid drinking grapefruit juice (or eating grapefruit) when taking it.

Recreational drugs

You must not take recreational drugs when using this treatment, as this is highly dangerous.

Driving and using machinery

You must not drive or use machines if you have any side effects that impede your ability to do so safely, and seek medical attention as soon as possible.

Can I still drink alcohol?

Alcohol can make erectile dysfunction worse, and reduce the effectiveness of the treatment. It is therefore recommended that you limit alcohol consumption when taking Vardenafil.

Will I still be able to drive?

Yes, provided you experience no side effects that make it dangerous for you to do so. If you do, do not drive, and speak to a doctor.

How do I store it?

Keep it at room temperature, and out of the reach of children.

Am I allergic to anything in the medicine?

Please consult the leaflet provided for a detailed list of ingredients.

Is it available over-the-counter?

No. Vardenafil is only available on prescription.
