ViagrON is used to treat erectile dysfunction, more commonly known as impotence, in men. This is when a man cannot get, or keep, a hard erect penis suitable for sexual activity.
ViagrON belongs to a group of medicines called phosphodiesterase type 5 inhibitors. It works by relaxing the blood vessels in your penis when you are sexually excited. This allows blood to flow into your penis, allowing you to get an erection in the natural way.
ViagrON will work only if you are sexually excited. ViagrON will not increase your sex drive.
ViagrON is not for use in women.
Before you take ViagrON
You must not take ViagrON if you are taking any nitrate medication. It may lead to a severe drop in your blood pressure, which may be difficult to treat. Because sexual activity may place a strain on your heart, your doctor will need to check whether you are fit enough to take ViagrON.
BEFORE YOU START TO TAKE VIAGRON
Tell your doctor if:
You have any allergies to any other medicines or any other substances such as foods, preservatives or dyes.
You have any other heart or blood vessel problems.
You have previously had sudden loss of eyesight in one or both eyes.
You have any of the following medical conditions:
- diabetes, especially if you also have eye problems
- kidney or liver problems
- leukaemia (cancer of the blood cells)
- multiple myeloma (a cancer of the bone marrow)
- any disease or deformity of your penis
- any bleeding disorder such as haemophilia
- stomach ulcer
- a disease of the blood called sickle cell anaemia
- colour vision problems
- previously experienced sudden decrease or loss of hearing.
You are receiving any other treatment for impotence.
You have any other medical conditions.
If you have not told your doctor or pharmacist about any of the above, tell them before you start taking ViagrON.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including medicines you buy without a prescription from a pharmacy, supermarket or health food shop.
Do not take ViagrON if you are using nitrate medicines for angina.
Some medicines and ViagrON may interfere with each other. These include:
- cimetidine, a medicine used to treat ulcers
- some medicines used to treat fungal infections including ketoconazole and itraconazole
- some antibiotics including erythromycin and rifampicin
- some protease inhibitors such as ritonavir and saquinavir for the treatment of HIV infection

These are used treat high blood pressure or prostate problems.
You may need different amounts of your medicine or you may need to take different medicines. Your doctor or pharmacist can tell you what to do if you are taking any of these medicines. They also have a more complete list of medicines to be careful with or avoid while taking ViagrON.
Ask your doctor or pharmacist, if you are not sure if you are taking any of these medicines.

WHILE YOU ARE TAKING VIAGRON

If ViagrON does not help you get an erection or if your erection does not last long enough to complete sexual intercourse, tell your doctor.
If you are about to start taking any new medicines, especially nitrates, tell your doctor and pharmacist that you are taking ViagrON.

If you experience changes in vision, or dizziness, when taking ViagrON, you should not drive or operate machinery.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking ViagrON.
If unwanted effects occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
- headache, dizziness;
- nasal congestion;
Tell your doctor as soon as possible if you notice any of the following:
- unusual heart beat

If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
- signs of allergy such as shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts
- chest pain
- sudden decrease or loss of hearing
