About Levitra

Buying Levitra online

  • Start an order by clicking on the ‘Start Order" button above
  • Complete a short online assessment by answering questions about your health and lifestyle
  • A Superdrug doctor will check your answers and approve treatment if it’s right for you

If Levitra is not right for you, you’ll get a message from a Superdrug doctor explaining this and offering advice on what to do next.

What is Levitra?

Levitra is an erectile dysfunction medication that helps you get and stay hard when you want to have sex. Levitra is a prescription-only medication, which means a doctor needs to approve the treatment before you can start taking it.


  • Takes 30 to 60 mins to start working
  • Lasts for 4 to 6 hours
  • Works for 54% to 74% of men who try it

Generic Levitra

Levitra is a branded medication that can only be manufactured by Bayer, but there is a generic medication that other companies can make called Vardenafil. Vardenafil works in the exact same way as Levitra, and has the same active ingredient, but can be a cheaper option as it is not branded.

How to take Levitra

  • Before taking Levitra, read the patient information leaflet that comes with your medication
  • Take Levitra one hour before you want to have sex
  • Swallow your tablet whole, with water if needed
  • Do not take Levitra more than once every 24 hours

For the best results:

  • Don’t eat a heavy meal before using Levitra
  • Avoid drinking alcohol
  • Avoid grapefruit juice

How does Levitra work?

Levitra belongs to a group of medications that are known as ‘PDE-5 inhibitors’. They work by relaxing the blood vessels in your penis, which increases blood flow to the area and helps you get an erection. Levitra will not help you get an erection if you are not aroused.

The effectiveness of Levitra is impacted by several factors, including:

  • the cause and severity of your ED
  • how aroused you are
  • your general health
  • whether you smoke (smoking can restrict blood flow)
  • whether you have drunk alcohol or taken drugs
  • whether you have eaten recently (Levitra works better on an empty stomach)
  • specifically whether you have eaten grapefruit (which impacts the body’s ability to digest Levitra)

Levitra dosages

There are 3 doses of Levitra: 5mg, 10mg, and 20mg. Higher doses of Levitra have a stronger effect, but may also increase the chances of the medication causing unwanted side effects.

Levitra 10mg

This is the standard dose of Levitra, and it’s the recommended starting dose if you haven’t tried it before. Levitra 10mg works for most men, and has a lower risk of side effects than 20mg.

Levitra 20mg

Levitra 20mg may be recommended if you’ve tried Levitra 10mg before, but didn’t see the results you wanted and you didn’t get serious side effects. 20mg is a stronger dose, so it can work for you when 10mg hasn’t, but it comes with a slightly higher risk of side effects.

Levitra 5mg

Levitra 5mg is only recommended if you tried a higher dosage and found you got side effects, or if you’re taking medication that makes Levitra treatment more risky. We do not offer this dose to buy online.

If you try Levitra and find that it is not effective for you, do not take more than you have been prescribed. Never switch the dose of your medication without the help of a doctor, as it may not be safe for you.

What are reviews of Levitra like?

Levitra is an effective treatment, but it doesn’t work for everyone:

  • It works for 54% to 74% of people who try it
  • Levitra has a rating of 8 out of 10 for erectile dysfunction treatment according to user reviews on drugs.com
  • On average, patients who used Superdrug Online Doctor to order Levitra rate it 4.4 out of 5 stars on TrustPilot.

Not sure if Levitra is right for you?

There are a number of different treatments for erectile dysfunction, so if you're not sure that Levitra is right for you then there are other options available. The most popular medications for treating erectile dysfunction are Viagra, Cialis, and Levitra. Each of these medications work slightly differently,

If you’re not sure which to choose, remember that all of these medications are effective and safe as long as a doctor approves treatment for you. We do not recommend one over the other.

If you need help choosing:

  • Higher dosage numbers does not mean the medication is stronger overall
  • Levitra and Viagra are about as effective as each other, and work in similar ways
  • If you want a longer-lasting medication, you might want to choose Cialis or Cialis Daily
  • If you don’t want to have to plan to take your medication before sex, you might want to choose Cialis Daily

For more information see our guide on choosing between Levitra, Viagra, and Cialis.

Levitra FAQs

When should I take Levitra for the best results?

Levitra should be taken at between 30-60 minutes before you want to have sex for the best results. This gives the medication time to reach its full effect and help you to get and maintain your erection. Try not to take Levitra just after a meal, especially a meal that is high in fat, as it can slow down the time it takes Levitra to start working. The effects can last for 4-5 hours.

What does a Levitra pill look like?

Levitra pills are round orange tablets, with an imprint on one side that shows what dose they are. For example, Levitra 20mg would have “20” imprinted onto the pill. On the other side there will be an imprint of “BAYER”, the manufacturer, in a cross pattern.

Are there any alternatives to Levitra?

There are several alternatives to Levitra, such as Viagra, Cialis and Spedra, which are prescription medications that work in similar ways. Devices such as penis pumps can also help to treat erectile dysfunction, and even can be used at the same time as medications for a better effect. Making changes to your lifestyle, such as exercising regularly or stopping smoking can also help improve your erectile dysfunction, as can addressing causes such as anxiety.

What’s the difference between Levitra and Viagra?

Levitra and Viagra both help with erectile dysfunction in a similar way, but contain different active ingredients and are available in different dosages.

Some men may find that one medication works better for them than the other, as they contain different active ingredients. However, because they work in the same way, you should not take both at the same time.

Does Levitra make you last longer?

If you find it difficult to keep an erection, Levitra can help you to get and maintain an erection, so you can stay harder for longer. However, if you are orgasming too quickly, then Levitra won’t help you last longer as it does not delay orgasm. If you are orgasming too quickly, you may want to try premature ejaculation treatment or techniques.

Can You Take Levitra With Alcohol?

While people sometimes use alcohol to try and overcome sexual anxiety, it can actually make it more difficult to get an erection. Because of this, drinking alcohol can make it harder for Levitra to work, and can also make the side effects of Levitra worse.

Can you get Levitra over the counter?

No, you can’t buy Levitra over the counter. Levitra is a prescription only medication, which means that a doctor needs to assess you to make sure that it is safe and appropriate for you to take it. This is because Levitra could be unsuitable if you have certain health conditions, or could interact with medications that you are taking.

What happens if a woman takes Levitra?

Women should not take Levitra, as it is only licensed for use by men in the UK. Some websites advertise products like “female Levitra” or “female Viagra” as medications to improve a woman’s sex drive, but these are not approved treatments and there is no evidence that these products actually work.

Can I take Levitra with other erectile dysfunction medications?

No, you should never take Levitra with another erectile dysfunction medication. Erectile dysfunction medications all work in the same way, so taking them together could cause serious side effects.

How much Levitra can you take at once?

You should only take one Levitra tablet per day, even if it’s a 2.5mg tablet (the lowest dose available). If you take more Levitra that your doctor has prescribed, then it may be unsafe as you have not been assessed for that dosage. In addition, the drug stays in your system for many hours, so taking more than one dose in a day might be dangerous.

Is it safe to buy Levitra online?

Yes, it is safe to buy Levitra online from trusted and regulated sellers like Superdrug Online Doctor.

Be aware when buying Levitra online - erectile dysfunction medications like Levitra and Viagra are some of the most counterfeited medicines in the world. These fake medications are likely to be ineffective, and at worst could be dangerous to take.

If you’re buying Levitra online in the UK, make sure that the company is registered with the Care Quality Commission (CQC) and the General Pharmaceutical Council (GPhC) who make sure that they are dispensing real Levitra, and that real doctors are prescribing it.

Does Levitra expire?

Levitra, like most medications, has a shelf life and can become less effective if it’s left unused for too long. You should check the expiry date on your packet, and make sure you take it before then. Levitra should be stored below 30°C and out of direct sunlight to make sure it lasts as long as it should.

What causes erectile dysfunction?

There are many different factors that can cause erectile dysfunction. Psychological factors such as stress or anxiety can cause erectile dysfunction, and so can physical problems with your circulation or nervous system. In most cases, there are multiple factors that cause erectile dysfunction, not just one. For more information, read our doctors’ advice on the causes of erectile dysfunction.
