Erectile Dysfunction (ED)

Levitra Side Effects — The Common And Uncommon Explained

by Andy Boysan

Levitra contains the active ingredient Vardenafil and is used to treat erectile dysfunction (ED) problems. It helps men achieve a harder and longer-lasting erection by encouraging muscle relaxation of the penile blood vessels, and therefore increasing blood flow, but can come with potential side effects.

Millions of men use medication like Levitra to enjoy a more active sex life, and it is licensed and classified as safe to use in the UK. However, every person reacts to medication differently. No matter how safe, there is potential to experience side effects when taking any drug, especially for the first time.

Most common side effects ofLevitra are mild; others are more serious, but less common. On this page, we’ll cover a list of the most common side effects, details about dosages, usingLevitra with alcohol, and possible allergic reactions. Equipped with this knowledge, you can then make your own mind up about whether you feel comfortable using Levitra. If you buy Levitra from The Independent Pharmacy you will always have a consultation with one of our qualified GPs first, to see if you're suitable for the treatment.


The most common side effects of Levitra

The most common side effects of Levitra include:

  • Headaches
  • Flushing
  • Running or blocked nose
  • Upset stomach
  • Indigestion
  • Dizziness
  • Back pain

Of the common side effects listed above, headache is the most common. All the common side effects of Levitra should be temporary and short-lived. That said, if you experience any of these side effects and they don’t go away within hours or worsen, it is recommended that you talk to a doctor.


Serious side effects of Levitra

Affecting fewer than one in 100 people, the less common side effects of Levitra include:

  • Vision loss
  • Ringing in your ears
  • Sudden hearing loss
  • Chest pain
  • A heavy feeling in the chest
  • Pain that spreads from the arm to the shoulder
  • Nausea
  • Prolonged sweating
  • Swelling (in the hands, ankles or feet)
  • Shortness of breath

In the rare event that you experience one of the side effects listed above, stop using Levitra immediately and consult your doctor.

Prolonged and painful erection after using Levitra

Levitra should be taken roughly an hour before you want to engage in sexual activity. The effects, on average, last for around five hours, and your erection will subside as normal after ejaculation.

Although uncommon, some men will experience a prolonged and painful erection after taking Levitra. In this rare event, stop using the medication and seek medical attention.


Can taking Levitra cause an allergic reaction?

Experiencing an allergic reaction to Levitra is rare but you do experience one, it can be extremely dangerous.

Symptoms of an allergic reaction to Levitra include:

  • Hives on the skin
  • Breathing problems
  • Swelling (of the face, lips, tongue or throat)

If you experience any of these possible allergic reactions to Levita, stop taking the medication immediately and talk to your doctor.


Using Levitra with Alcohol

Drinking alcohol often forms part of a romantic evening. For most men, mixing alcohol and Levitra will be safe. In fact, studies have shown that there are no significant adverse effects when using alcohol and Levitra. That said, alcohol reduces blood pressure, which can reduce the erection-providing benefits that Levitra provides. Although rare, combining the drug with alcohol can also increase the likelihood of experiencing side effects.


Mixing Levitra with other medications

Levitra is not suitable to take at the same time as other erectile dysfunction drugs, including ViagraSildenafil, Tadalafil, and Cialis or Viagra Connect offers an over the counter alternative.

A list of other drugs and medications that may react badly with Levitra include:

  • Some antibiotics
  • Antifungal medication
  • Heart or blood pressure medicines
  • Medicines to treat angina (nitrates)
  • Heart rhythm medicine (alpha blockers)
  • Medicine for HIV/AIDS

If you take any of the medications listed above, tell your doctor before taking Levitra, who will be able to advise on whether the drug is safe for you to use.


Other substances that may react badly with Levitra

There are several other substances that when mixed with Levitra, may cause an adverse reaction. These include:

  • Herbal products and supplements such as St John's wort
  • Grapefruit and grapefruit juice
  • High-fat meals such as steak
  • Tobacco products

If you smoke or eat a lot of high-fat meals, ask your doctor for advice about taking Levitra. Both can make the ED medication less effective and can cause results that will disappoint.


Are the possible side effects of Levitra worth it? 

If you are fit and healthy, it is highly unlikely that you will have a bad experience when using Levitra. If you do suffer from side effects, again, they are likely to be mild. In this case, it’s up to you whether the erection-providing benefits of the drug are worth it. If you find that Levitra is not as effective as you hoped, Viagra is a popular alternative. You can read about the differences on our Levitra vs Viagra page.


How to reduce the side effects of Levitra

In the vast majority of cases, you won’t need to do anything to reduce Levitra side effects — when mild, they should subside after a short time. The most common side effect of Levitra is a headache, but again, these should be mild and short-lived. 


When you should seek medical advice after taking Levitra

As outlined above, if you suffer side effects after taking Levitra, they are usually mild. In the unlikely event that the side effects are more severe, you will need to seek immediate medical advice. Here’s how to tell if you need to seek a doctor:

You’ve had an allergic reaction: Hives on the skin, breathing problems, and swelling of the face, lips, tongue or throat are signs of an allergic reaction to Levitra.

You’re experiencing chest pain: Levita does not mix well with most forms of heart medication. Sexual activity also gets the heart racing. If you experience chest pain, stop immediately.

You have an erection that has lasted over five hours: After arousal, sexual activity and ejaculation, your erection should subside, If it lasts longer and is painful, you could suffer from permanent damage.

Your vision becomes impaired: Blurred vision may be temporary. Sometimes, it’s a sign something is wrong.

You’ve suffered a seizure: Although rare, having a seizure is very serious and worrying. If you have one, seek medical assistance as soon as possible.



On the whole, Levitra is safe to use. Most side effects caused by the medication are mild and short-lived. As long as you are healthy — for example, no history of heart disease — you should be able to enjoy the benefits of a happy sex life that Levitra can provide.

At the Independent Pharmacy, we can help you buy Levitra. After taking a short online consultation with one of our registered doctors, if you are safe to take the medication, we offer next-day delivery in discreet packaging.
