Patient leaflet - Vardenafil Zentiva 10 mg film-coated tablets

1. What Vardenafil is and what it is used for

The name of your medicine is Vardenafil Zentiva 5 mg, 10 mg and 20 mg film- coated tablets (called Vardenafil throughout this leaflet). It 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 have 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 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 allows an erection to last long enough for you to satisfactorily complete sexual activity.

2. What you need to know before you take

Do not take Vardenafil 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.
  • you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking Vardenafil.
  • 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 could seriously affect your blood pressure. • you are taking ritonavir or indinavir, medicines used to treat human

    immunodeficiency virus (HIV) infections. • you are over 75 years of age and are taking ketoconazole or itraconazole, anti-fungal medicines.

  • you have a severe heart or liver problem. • you are having kidney dialysis.
  • you have recently had a stroke or heart attack.
  • you have or have had low blood pressure. • your family has a history of degenerative eye diseases (such as retinitis pigmentosa). • 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).
  • 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 have been shown to increase the hypotensive effects of this medicine. If you are taking riociguat or are unsure tell your doctor. Warnings and precautions

Talk to your doctor or pharmacist before taking Vardenafil if you

  • have heart trouble. It may be risky for you to have sex.

    • suffer from irregular heart beat (cardiac arrhythmia) or inherited heart diseases affecting your electrocardiogram. • have a physical condition affecting the shape of the penis. This includes conditions called angulation, Peyronie’s disease and cavernosal fibrosis.
    • have an illness that can cause erections which won’t go away (priapism). These include sickle cell disease, multiple myeloma and leukaemia.
    • have stomach ulcers (also called gastric or peptic ulcers).
    • have a bleeding disorder (such as haemophilia).
    • are using any other treatments for erection difficulties, including vardenafil- containing orodispersible tablets (see section “Other medicines and Vardenafil”).

Serious skin reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, have been reported in association with vardenafil treatment. Stop using Vardenafil and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4. If you experience sudden decrease or loss of vision or your vision is distorted or dimmed while you are taking Vardenafil, stop taking Vardenafil and contact your doctor immediately.

Children and adolescents

Vardenafil is not intended for use by children or adolescents under 18.

Other medicines and Vardenafil

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Some medicines may cause problems, especially these:

  • Nitrates, medicines for angina, or nitric oxide donors, such as amyl nitrite. Taking these medicines with Vardenafil could seriously affect your blood pressure.
  • Medicine for the treatment of arrhythmias, such as quinidine, procainamide, amiodarone or sotalol.
  • Ritonavir or indinavir, medicines for HIV. • Ketoconazole or itraconazole, anti-fungal medicines.
  • Erythromycin, or clarithromycin, macrolide antibiotics.
  • α-blockers, a type of medicine used to treat high blood pressure and enlargement of the prostate (as benign prostatic hyperplasia). • Riociguat.
  • Do not use Vardenafil film-coated tablets combined with any other treatment for erectile dysfunction, including vardenafil-containing orodispersible tablets. Vardenafil with food, drink and alcohol

You can take Vardenafil with or without food, but preferably not after a heavy or high-fat meal as this may delay the effect.

Don’t drink grapefruit juice when you use Vardenafil. It can interfere with the usual effect of the medicine.

Alcoholic drink can make erection difficulties worse.

Pregnancy, breast-feeding and fertility

Vardenafil is not for use by women. Driving and using machines

Vardenafil might make some people feel dizzy or affect their vision. If you feel dizzy or if your vision is affected after taking Vardenafil don’t drive or operate any tools or machines.

3. How to take Vardenafil

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. The recommended dose is 10 mg.

Take a Vardenafil tablet about 25 to 60 minutes before sexual activity. With sexual stimulation you may achieve an erection anywhere from 25 minutes up to four to five hours after taking Vardenafil.

Swallow one tablet with a glass of water. Do not take Vardenafil film-coated tablets with any other forms of vardenafil.

Do not take Vardenafil more than once a day. Tell your doctor if you think Vardenafil is too strong or too weak. He or she may suggest a switch to an alternative vardenafil formulation with a different dose, depending on how well it works for you.

If you take more Vardenafil than you should

Men who take too much Vardenafil may experience more side effects or may get severe back pain. If you take more vardenafil than you should, tell your doctor.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
