Patient leaflet - Vardenafil Krka 10 mg film-coated tablets

1. What Vardenafil Krka is and what it is used for

Vardenafil Krka contains vardenafil, a member of a class of medicines called phosphodiesterase type 5 inhibitors. They are

used for the treatment of erectile dysfunction in adult men, a condition which implies difficulties in getting or keeping an erection. At least one in ten men has trouble getting or keeping an erection at some time. There may be physical or psychological causes, or a mixture of both. Whatever the cause is, due to muscle and blood vessel changes not enough blood stays in the penis to make it hard and keep it hard.

Vardenafil Krka will only work when you are sexually stimulated. It reduces the action of the natural chemical in your body which makes erections go away. Vardenafil Krka allows an erection to last long enough for you to satisfactorily complete sexual activity.

2. What you need to know before you take Vardenafil Krka

Do not take Vardenafil Krka

  • If you are allergic to vardenafil or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include a rash, itching, swollen face or lips and shortness of breath.
  • If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking Vardenafil Krka.
  • If you are taking medicines containing nitrates, such as glycerol trinitrate for angina, or nitric oxide donors, such as amyl nitrite. Taking these medicines with Vardenafil Krka could seriously affect your blood pressure.
  • If you are taking ritonavir or indinavir, medicines used to treat human immunodeficiency virus (HIV) infections.
  • If you are over 75 years of age and are taking ketoconazole or itraconazole, anti-fungal medicines.
  • If you have a severe heart or liver problem.
  • If you are having kidney dialysis.

    • If you have recently had a stroke or heart attack.
    • If you have or have had low blood pressure.
    • If your family has a history of degenerative eye diseases (such as retinitis pigmentosa).
    • If you have ever had a condition involving loss of vision due to damage to the optic nerve from insufficient blood supply known as non-arteritic ischemic optic neuropathy (NAION).
    • If you are taking riociguat. This drug 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, such as Vardenafil Krka have been shown to increase the hypotensive effects of this medicine. If you are taking riociguat or are unsure tell your doctor.
