1. WHAT IMDUR IS AND WHAT IT IS USED FOR
Imdur contains a medicine called isosorbide mononitrate. This belongs to a group of
medicines called 'nitrates'.
• It is used to prevent chest pain (angina).
• It works by making the blood vessels relax and widen. This makes it easier for the
heart to pump blood around the body.
The tablets are made so that they release the medicine slowly over a number of hours.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE IMDUR
Do not take Imdur:
• If you are allergic to isosorbide mononitrate or any of the other ingredients of this
medicine (listed in section 6).
• If you have ever had a stroke.
• If you have very low blood pressure.
• If you have severe anaemia.
• If you have a heart problem called 'cardiomyopathy' or 'pericarditis' or you have
narrow heart valves.
• If you are taking sildenafil or similar medicines called Phosphodiesterase Type 5
Inhibitors, (used for male impotence). See the section “Other medicines and Imdur”.
Do not take Imdur if any of the above apply to you. If you are not sure, talk to your
doctor or pharmacist before taking Imdur.
Warnings and precautions
Talk to your doctor or pharmacist before taking Imdur if:
• You have ever had any serious damage to your heart, such as a heart attack or
operation.
If any of the above apply to you, or you are not sure, talk to your doctor or pharmacist
before taking Imdur.
Other medicines and Imdur
Tell your doctor or pharmacist if you are taking, have recently taken or might take any
other medicines. This includes medicines that you buy without a prescription and herbal
medicines. This is because Imdur can affect the way some medicines work and some
medicines can have an effect on Imdur.
Do not take Imdur if you are taking the following medicines:
• Sildenafil or similar medicines called Phosphodiesterase Type 5 Inhibitors, (used for
male impotence).
Do not take Imdur if any of the above apply to you. If you are not sure, talk to your
doctor or pharmacist before taking Imdur.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to
have a baby, ask your doctor or pharmacist for advice before taking this medicine.

machines.
3. HOW TO TAKE IMDUR
Always take this medicine exactly as your doctor or pharmacist has told you. Check
with your doctor or pharmacist if you are not sure.
Taking this medicine
• Swallow the tablets whole or broken in half (if this is easier to swallow).
• Take the tablets with half a glass of water.
• Do not crush or chew the tablets.
How much to take
• The recommended dose is one or two tablets a day.
• Take the medicine in the morning.
• Your doctor may ask you to start on a low dose so that you are less likely to have a
reaction to starting Imdur.
• The blister strips are marked with the days of the week. If you are taking two tablets a
day, make sure you take one tablet from each strip marked with the same day of the
week.
You must not take Imdur 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.

Use in children
Do not give these tablets to children.
If you take more Imdur than you should
If you take more Imdur than you should, talk to a doctor or go to a hospital straight
away. Take the medicine pack with you so the tablets can be identified.
If you forget to take Imdur
• 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 forgotten dose.
