1. What Nitro-Dur is and what it is used for
Nitro-Dur is an adhesive patch containing Glyceryl Trinitrate (GTN). This
is one of a group of medicines called nitrate vasodilators which are used
to treat the symptoms of angina (chest pain). Vasodilators are drugs that
cause widening of the blood vessels and therefore an increase in blood
flow. The GTN is contained in the adhesive and when the patch is in
contact with the skin the GTN passes slowly and steadily from the patch
through the skin and into the bloodstream.
Angina usually occurs as a pain or tightness in the chest although it may
be felt in the neck or arm. The pain occurs when the heart muscle does
not receive the oxygen it needs to do the work it has to do. Nitro- Dur is
used to prevent symptoms of angina; it is not for treatment of an acute
attack. You should use your usual tablets or spray under the tongue for
treatment of acute attacks.
2. Before you use Nitro-Dur
Do not use Nitro-Dur if you:
 are allergic (hypersensitive) to GTN or any of the other ingredients of
 suffer a head injury
 are anaemic (have low levels of haemoglobin – a substance contained
within the red blood cells which is responsible for carrying oxygen
around the body)
 have heart problems other than angina or have low blood volume or
 are taking medicines for erectile dysfunction, for example sildenafil,
tadalafil or vardenafil. If these medicines are used together a severe
and possibly dangerous fall in blood pressure can occur. This could
result in collapse, unconsciousness and could be fatal.

Take special care with Nitro-Dur if you:
 have had recent heart failure or a heart attack
 have lung disease
 have or have previously suffered from closed-angle glaucoma (an
increase in pressure in the eye causing visual disturbances)

4. Hold the patch with the brown lines facing you
in an up and down position.

Taking other medicines while using Nitro-Dur
Taking beta blockers, ACE inhibitors, calcium channel blockers, diuretic
medicines or other medicines to lower your blood pressure or medicines
for anxiety or depression at the same time as Nitro-Dur may lower your
blood pressure further.
Taking Nitro-Dur with dihydroergotamine, a medicine used to treat
migraine, can affect the blood vessels in the heart.
The effect of Nitro-Dur may be reduced if you take pain killers such as
aspirin or anti-inflammatory medicines at the same time as you use your
patch. Please tell your doctor or pharmacist if you are taking or have
recently taken any other medicines, including medicines bought without a

are affected in this way.
3. How to use Nitro-Dur
Always use Nitro-Dur exactly as your doctor has told you. You should
check with your doctor or pharmacist if you are not sure. The usual dose
is one patch daily. Your doctor may tell you to remove the patch after a
period shorter than 24 hours. He may also tell you to apply the patch in
the morning or at night. You should usually apply a new patch at the
same time each day.
Put the new patch on a different area of clean, dry skin.
Children should not use Nitro-Dur
How to apply your patch

If you use more Nitro-Dur patches than you should
If you or someone else applies too many patches at once, remove the
patches carefully and wash the skin thoroughly to prevent any more
medicines being absorbed. Too much GTN can cause your blood
pressure to drop, make you feel light-headed or cause you to faint.
If you forget to use your Nitro-Dur patch
If you forget to change your patch, do so as soon as you remember. Then
go on as before. Do not apply two patches to make up for the forgotten

If you stop using Niro-Dur
Do not stop using your patches without talking to your doctor. If you want
to stop your treatment this must be done gradually and your doctor will
need to give you a different medicine to control your angina.
4. Possible side effects
Like all medicines Nitro-Dur can cause side effects, although not
everyone gets them.
 Headache is the most common side-effect. You can take some mild
pain killers (such as paracetamol) for this (if they continue or are very
severe, do consult your doctor).
 Faintness or dizziness
 A fast heart beat or pulse.
 Rarely in some patients the heartbeat may slow and angina may get
 Redness or irritation of the site where you have placed the patch (some
redness is normal but this should disappear in a short time).
If any of the side effects gets serious or if you notice any side effects not
listed in this leaflet, please tell your doctor or pharmacist.
