This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.

1. What Monomax is and what it is used for

Monomax XL Prolonged-release Tablets contain isosorbide mononitrate which belongs to a group of medicines called nitrates that act on the cardiovascular system (the heart and blood vessels). Monomax has been given to you by your doctor or pharmacist to reduce the frequency of your anginal attacks (chest pains).

They are called prolonged-release tablets because they are manufactured in a way that allows the isosorbide mononitrate to be released and slowly absorbed by your body over a period of several hours.

In angina, isosorbide mononitrate works by opening up the arteries supplying the heart muscle and this allows more blood and oxygen to reach the muscle, decreasing the chances of angina (chest pains) occurring when extra strain is placed upon the heart.

2. What you need to know before you take Monomax

Do not take Monomax:

if you are taking the drug, sildenafil or similar medicines called Phosphodiesterase Type 5 Inhibitors, for the treatment of male erectile dysfunction (see also: Section 2 - Taking other medicines)
if you are allergic to isosorbide mononitrate, other nitrates (e.g glyceryl trinitrate or isosorbide dinitrate) or any of the other ingredients in Monomax (listed in section 6)
if you have suffered a stroke or have any other condition which may affect the blood supply to your brain
if you suffer from low blood pressure
if you have been told that you have a problem with your heart such as ‘cardiomyopathy’ or ‘pericarditis’ or you have narrow heart valves. Ask your doctor if you are not sure if this applies to you
if you suffer from a reduction in red blood cells which can make the skin pale and cause weakness or breathlessness
to treat an angina attack as it occurs. Your doctor will probably have given you another tablet to take for sudden attacks.

Take special care with Monomax and always tell your doctor or pharmacist if:

you suffer from increased pressure in your eyes
you suffer from an underactive thyroid gland
you suffer from an abnormally low body temperature
you suffer from poor health caused by a poor diet
you suffer from severe liver or kidney disease
you have suffered from a head injury or bleeding in the brain
you have ever had any serious damage to your heart, such as a heart attack or operation.

Taking other medicines

Before starting treatment, please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. If you have to go to a doctor, dentist or hospital for any reason, tell them that you are taking Monomax.

In particular, tell your doctor or pharmacist if you are taking:

medicines for the treatment of high blood pressure, such as hydralazine or minoxidil
water tablets, such as frusemide

Taking these types of medicines with Monomax can increase the risk of low blood pressure occurring, especially if you are elderly.

Do not take sildenafil, or similar medicines called Phosphodiesterase Type 5 Inhibitors used for the treatment of erectile dysfunction at the same time as Monomax. If taken at the same time it could cause a severe fall in blood pressure resulting in collapse, unconsciousness and may be fatal.

Taking Monomax with food, drink and alcohol:

If you drink alcohol while you are taking Monomax it can increase the risk of low blood pressure occurring, especially if you are elderly.

Pregnancy, breast-feeding and fertility:

Do not take Monomax if you are pregnant, trying to become pregnant or are breast- feeding.

Driving and using machines:

If you feel faint, dizzy or light headed when you stand up or move suddenly after taking Monomax, then do not drive or operate machinery.

Important information about some of the ingredients of Monomax:

Monomax contains lactose monohydrate. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

3. How to take Monomax

Always take Monomax exactly as your doctor or pharmacist has told you to. You should check with your doctor or pharmacist if you are not sure.

The label on the carton will tell you how many tablets you should take and when. It is very important that you take your tablets regularly. Do not stop treatment even if you feel better unless told to do so by your doctor.

Monomax is formulated so that you only have to take your tablets once a day.

It is important that you take your tablets at the same time each day, preferably in the morning. Your tablet may be swallowed whole or broken in half if this is easier and swallowed with a glass of water. Do not crush or chew your tablets.

Adults and the elderly: the usual dose is 60 mg once a day. Your doctor may decide to increase your dose to a maximum of 120 mg of Monomax once a day. To reduce the possibility of headaches you may initially be given half a tablet (30 mg) once a day for the first 2-4 days.

If you are elderly and suffer from low blood pressure, liver or kidney disease, your doctor may prescribe a lower dose for you to take.

Do not stop taking your medicine until your doctor tells you.

Children must not take this medicine.

You must not take Monomax for a sudden attack of angina. If you have a sudden attack, take a glyceryl trinitrate tablet (follow the instructions given on the label).

Very occasionally, some people see the remains of the tablet in their bowel motions.

This is quite normal and does not mean that the medicine has not been released.

If you take more Monomax than you should

If you accidentally take more Monomax than you should, contact your nearest casualty department or tell your doctor or pharmacist immediately. Remember to take the pack and any remaining tablets with you.

If you forget to take Monomax

If you forget a dose, take it as soon as you remember it. However, if it is nearly time for the next dose, skip the missed dose. Do not take a double dose to make up for a missed dose.

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

4. Possible side effects

Like all medicines, Monomax can cause side effects, although not everyone gets them.

If you experience a headache when you first start taking your tablets, contact your doctor or pharmacist immediately. Your doctor or pharmacist may need to adjust your dose.

The following side effects do not usually last long and are most likely to occur when you first start to take your medicine or if your dose has been increased. If they continue or if you are worried, contact your doctor or pharmacist immediately:
