What is Vardenafil Used to Treat?

Vardenafil tablets are used to treat erectile dysfunction in men. Erectile dysfunction is the inability to achieve and maintain an erection that is sufficient for satisfactory sexual performance.

How to Take Vardenafil

Varednafil Tablets

Vardenafil is usually taken between 25 and 60 minutes before sexual activity. Patients should only take vardenafil as directed by the prescribing clinician. If there are no other medical issues, it is usually safe to take vardenafil tablets once each day. We do not recommend taking more than is needed. Although vardenafil and other medicines used to treat erectile dysfunction, including sildenafil and tadalafil, are linked to achieving an erection, taking vardenafil on its own is not usually sufficient to cause an erection. The man usually has to be sexually aroused for an erection to occur.

What Are the Side Effects of Vardenafil?

Vardenafil is generally well tolerated. As with any medicine, side effects can occur. The side effects tend to be mild. These side effects can include headache, dizziness, nausea, back pain, muscle aches, and occasionally facial flushing. Some reports of dyspepsia and heartburn have been reported as well as patients occasionally experiencing nasal congestion following a dose.

Who Should Not Use Vardenafil?

  • Vardenafil is only intended for use by men and is not intended for use by women.
  • Patients that have allergies or hypersensitivities to vardenafil or any of the ingredients within the tablet must not take this medicine.
  • Patients that take nitrates must not use vardenafil. Nitrates are often used for angina treatment.
  • If you have hypotension (low blood pressure of less than 90/50 mmHg), you must not take vardenafil.
  • Those with severe hepatic (liver) failure must not use this medicine.
  • There are some age-related specific contraindications (reasons why vardenafil tablets must not be taken), which include patients over 75 years of age who are also taking medicines such as ketoconazole and itraconazole in oral form.
  • Patients that are being treated with HIV protease inhibitors including ritonavir and indinavir must not take vardenafil.
  • If you have been told to abstain from certain forms of exercise, this may also be a reason why vardenafil tablets should not be taken. Some patients may have cardiovascular conditions that mean the additional strain of having sexual intercourse can cause a significant risk.

There are other reasons why vardenafil may not be advised. The above is just a summary and is not an exhaustive list. Always follow the advice of the doctor (or other suitable clinician) prescribing the medicine and act on the information in the patient information leaflet supplied with any medicines that you receive. An example patient information leaflet that should be read before using vardenafil tablets is available online. Click here to see the patient information leaflet (this link opens in a new tab).


You must always let the prescriber know the medicines you are taking as well as your conditions including all current, dormant, and recently resolved conditions. Always let the prescriber know if you are taking any short course of treatments for example antibiotics for a chest infection or urine infection. You must let the clinician that is assessing you for the suitability of vardenafil know about all your current symptoms, because even those that you may not associate with erectile dysfunction may mean that the medicine either does not work correctly or further investigation is needed for safe diagnosis and treatment.

For patients that are prescribed vardenafil for the first time, a 10mg dose is usually prescribed. This dose may be decreased to 5mg in some cases, for example when patients have severe renal failure. Based on how well this works and how well the medicine is tolerated, the prescriber may suggest increasing the strength or decreasing the strength. The usual maximum dose of vardenafil is 20mg. Note that tablets may be taken with or without food. We recommend that vardenafil tablets are taken with a glass of water to aid swallowing.

Vardenafil tablets are only suitable for adults and must not be taken by people under the age of 18 years unless on medical advice.
