Frequently asked questions
  • What is vardenafil and how does it work?

    Vardenafil is an erectile dysfunction treatment. It belongs to a class of medicines called PDE5 inhibitors. It works by relaxing the blood vessels in the penis, increasing blood flow to support an erection when you're sexually aroused. Vardenafil only works with sexual stimulation, so it won't cause an unexpected erection. Many men notice effects within 15 to 30 minutes, with results lasting up to around five hours. It works in a similar way to Viagra tablets, though some men find one suits them better than the other.

  • What is the dosage guidance?

    Vardenafil is available in 5mg and 10mg strengths. Take one tablet with a glass of water roughly 25 to 60 minutes before sexual activity. Do not take more than one tablet in a 24-hour period, as exceeding the recommended dose can increase the risk of side effects. Your clinician will advise on the strength that's most appropriate for you.

  • Is vardenafil right for you?

    Vardenafil is suitable for many men with ED, including those with diabetes. However, it isn't suitable for everyone - for example, if you take nitrate medicines for chest pain or have certain heart conditions. During your confidential online consultation, our clinicians will review your medical history and current medications to ensure vardenafil is safe and appropriate for you.

  • What are the contraindications?

    • If you are allergic to avanafil or any of the other ingredients of this medicine

    • If you are taking “nitrate” medicines for chest pain (angina), such as amyl nitrite or glyceryl trinitrate. Spedra can increase the effects of these medicines and severely lower your blood pressure

    • If you are taking medicines for HIV or AIDS such as ritonavir, indinavir, saquinavir, nelfinavir or atazanavir

    • If you are taking medicines for fungal infections such as ketoconazole, itraconazole or voriconazole or certain antibiotics for bacterial infections, such as clarithromycin or telithromycin

    • If you have a serious cardiac problem

    • If you have had a stroke or heart attack in the last 6 months

    • If you have low blood pressure or high blood pressure not controlled by medicines

    • If you have chest pain (angina) or you get chest pain during sexual intercourse

    • If you have a serious liver or kidney problem

    • If you have loss of vision in one eye due to not enough blood getting to your eye (non-arteritic ischemic optic neuropathy [NAION])

    • If certain serious eye problems run in your family (such as retinitis pigmentosa).

    • If you are taking riociguat. This medicine is used to treat pulmonary arterial hypertension (i.e., high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e., high blood pressure in the lungs secondary to blood clots). PDE5 inhibitors have been shown to increase the hypotensive effects of this medicine.

  • What are the side effects?

    Like all medicines, this medicine can cause side effects, although not everybody gets them.

    Most of the effects are mild or moderate.

    Partial, sudden, temporary or permanent decrease or loss of vision in one or both eyes has been experienced by patients. Stop taking Vardenafil and contact your doctor immediately.

    Sudden decrease or loss of hearing has been reported.

    Cases of sudden death, fast or altered heart beat, heart attack, chest pain, and trouble in cerebral circulation (including temporarily decreased blood flow to parts of the brain and bleeding in the brain) have been reported in men taking vardenafil. Most of the men who experienced these side effects had heart problems before taking this medicine. It is not possible to determine whether these events were directly related to vardenafil.
