1. What Monomax is and what it is used for
Monomax SR Modified-release Capsules 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 modified-release capsules 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, 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
• 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 suffer from a reduction in red blood cells which can make the skin pale and cause weakness and breathlessness
• if you have been told that you have a problem with your heart. Ask your doctor if you are not sure if this applies to you
• 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 been told that you have a narrowing of the valves in your heart
• you become dizzy, light headed or faint when you stand up
• you have suffered from a head injury or bleeding in the brain.
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
• medicines to treat the symptoms of depression, such as amitriptyline or imipramine
• medicines to treat a mental condition, such as chlorpromazine or methotrimeprazine
• 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, 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, unconciousness and may be fatal.
Taking Monomax with alcohol
Do not take Monomax at the same time as an alcoholic drink.
Pregnancy, breast-feeding and fertility:
Do not take Monomax if you are pregnant, trying to become pregnant or are breastfeeding.
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 and sucrose. 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.

Adults and the elderly: the usual dose is 40 mg or 60 mg once a day. Your doctor may decide to increase your dose to a maximum of 120 mg of Monomax once a day.

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