1. WHAT ISIB 60 XL IS AND WHAT IT IS
ISIB 60 XL Prolonged Release Tablets (referred
to as ISIB 60 XL throughout this leaflet)
contains an active substance called Isosorbide
Mononitrate. This belongs to a group of
medicines called 'nitrates'.
• It is used to prevent chest pain (angina).
Angina is a crushing pain or tightness in the
chest, although the pain may also be felt in
the neck or arm. The pain happens when the
muscle in the heart does not receive enough
oxygen for the work it has to do. ISIB 60 XL
works by improving the supply of blood
and oxygen to the heart muscle. The tablets
will release your medicine slowly and will treat
your condition throughout the day.
• It works by making the blood vessels
relaxed 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 ISIB 60 XL
Do not take ISIB 60 XL:
DO NOT use these tablets to treat sudden
chest pain (acute angina). Instead seek
immediate medical attention. These tablets
work too slowly to treat this and are only used
to prevent symptoms of angina from happening.
• If you are allergic (hypersensitive) to
isosorbide mononitrate or any of the other
ingredients of ISIB 60 XL (listed in
Section 6: Further information).
• 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 ISIB 60 XL".
Do not take ISIB 60 XL if any of the above
apply to you.
If you are not sure, talk to your doctor or
pharmacist before taking ISIB 60 XL.
