6. Contents of this pack and other information
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. What you need to know before you use Nitro-Dur
Do not use Nitro-Dur if you:
 are allergic to GTN or any of the other ingredients of Nitro-Dur.
 have had a head injury or a condition which could cause an increase in
pressure within your head.
 have a low blood pressure or have a decrease in your blood pressure.
 have recently suffered from blood loss
 have heart problems other than angina
 are taking medicines for erectile dysfunction, for example Viagra
(sildenafil), Cialis (tadalafil) or Levitra (vardenafil). If these medicines
are used together a severe and possibly dangerous fall in blood
pressure can occur.
 are taking Adempas (riociguat) for increased blood pressure of the
pulmonary arteries or veins. If these medicines are used together it can
lead to low blood pressure.
 Closed angle glaucoma (an increase in pressure in the eye)

Take special care with Nitro-Dur if you:
 have had recent heart failure or a heart attack. Please ask your doctor
for further advice
 have low levels of oxygen in their blood due to lung disease
 experience angina whilst using Nitro-Dur
 develop low blood pressure – removal of the patch maybe considered.
 have a low blood volume for example after taking “water tablets” which
may cause a low blood pressure
 have or develop low blood pressure
 have a low thyroid level, are malnourished, have liver or kidney
problems, have an enlarged heart or have recently suffered a heart
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 or antiinflammatory medicines at the same time as you use your patch, with the
exception of aspirin. However Aspirin when taken with Nitro-Dur and
other medicines may cause your blood pressure to fall. Please tell your
doctor or pharmacist if you are taking or have recently taken these or any
other medicines, including medicines bought without a prescription.
Do not use phosphodiesterase inhibitors in any form or with products that
are soluble guanylate cyclase stimulators.
Using Nitro-Dur with food and drink
Be careful when drinking alcohol with this medicine, as it may cause your
blood pressure to fall.
Pregnancy, breast feeding and fertility
You should not usually use Nitro-Dur if you are pregnant or breast
feeding. If you are pregnant or breast-feeding, think you may be pregnant
or are planning to have a baby ask your doctor for advice before taking
this medicine.
Driving and using machines
The patches may impair reactions or rarely cause dizziness. Do not drive
or use machines if you 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

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
