What Transiderm-Nitro is used for

a medicine called glyceryl trinitrate through the skin and into the bloodstream.
Transiderm-Nitro belongs to a group of medicines called nitrates. Nitrates work by
widening blood vessels, letting more blood and oxygen reach the heart.

How to use Transiderm-Nitro
Follow all directions given to you by your doctor and pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist
How much to use
Your doctor may start your treatment with one Transiderm-Nitro 25 patch each day for
several days and then change to the larger Transiderm-Nitro 50 patch. The usual dose
for most people is one Transiderm-Nitro 50 patch each day, although some people may
need more or less.
When to use it
You will normally apply a patch once each day, usually in the morning.
Your doctor will likely ask you to take the patch off for 8 to 12 hours out of every
24 hours (e.g. take it off at bedtime and put a new one on when you wake up in the
morning). This "patch off" period may make the medicine more effective.
How to apply the patch
Follow these steps to apply a patch to your skin.
1. Choose an area of skin:
The best place is your chest but you may use any area except below your knees or elbows.
Choose an area of skin that has no sores, cuts or rashes.
If the skin is very hairy, you can clip the hair (do not shave it) so that the patch
sticks well and won't be hard to remove.
Use a different area of skin each day. Wait several days before using the same area
2. Make sure the skin is clean, cool, dry and free from creams, lotions or oils:
You may need to wash the area with soap and water and dry it completely.
If your skin is very oily, you can use methylated spirits to clean it, then dry it
After a shower or bath, wait a few minutes before applying the patch to make sure
your skin is completely cool and dry.
You may use body lotion or bath oil after the patch has been applied.
3. Open the sachet that contains the patch:
Tear open the sachet at the notch and remove the patch.
Do not use scissors because you may accidentally cut the patch and the medicine may
Any air bubbles on the patch are not important.
4. Remove the protective liner from the sticky side of the patch:
Pick up the patch with the tab upwards and the white liner facing you.
Firmly bend the tab forward with your thumb.
Use both thumbs to peel off the protective liner, starting at the tab. Do not touch
the sticky surface of the patch.
Throw the liner away.
5. Apply the patch to the skin as soon as you have removed the liner:
Press the sticky side of the patch to the area of skin you have chosen so that the
tan coloured side is showing.
Press the patch firmly in place with the palm of your hand for 10 to 20 seconds. The
patch needs the pressure and heat of your hand to stick well.
Check that the patch has stuck by running your finger around the edge. Do not try
to lift the edge of the patch to see if it has stuck.
How to remove the patch
Use the little tab to pull the patch away from your skin.
Fold the old patch in half with the sticky side inwards.
Throw the old patch away safely out of the reach of children. The patch still contains
some leftover medicine that could harm a child.
Remove any stickiness from the skin with soap and water or methylated spirits.
If the patch falls off
Throw the patch away.
Apply a new patch to a different area of clean, dry skin.
Change the patch at the next time that you would normally change it.
Bathing, swimming, showering or exercising will usually not affect the patch if it
has been correctly applied.
If the patch irritates your skin
Check that water has not gotten under the patch. If it has, remove the patch and apply
a new one to a different area.
Try a less sensitive area, for example your upper arm.
Use a new area of skin for each patch. Do not use the same area of skin for at least
You can use a mild cream on the sore area once the patch has been removed.
How long to use it
Use Transiderm-Nitro for as long as your doctor tells you to.
Otherwise, you may not get relief from your attacks of angina. Try not to miss any
doses and use the medicine even if you feel well.
Do not stop using Transiderm-Nitro suddenly.
Stopping this medicine suddenly may bring on attacks of angina, especially if you
have been using it for several weeks or more. If you want to stop using it, your doctor
will tell you how to do it gradually (e.g. over 4 to 6 weeks) to avoid making your
If you forget to use it
If it is almost time to apply your next patch, skip the one you missed and apply the
next patch when you are meant to.
Otherwise, apply the patch as soon as you remember, respecting any prescribed patch-off
period and then go back to using it as you would normally.
Do not use a double dose to make up for the one that you missed.
This may increase the chance of you getting an unwanted side effect.
If you have trouble remembering when to use your medicine, ask your pharmacist for
If you use too much (overdose)
Remove the patch. Immediately telephone your doctor or Poisons Information Centre
(telephone 13 11 26), or go to Accident and Emergency at your nearest hospital, if
you think that you or anyone else may have used too much Transiderm-Nitro. Do this
even if there are no signs of discomfort or poisoning. Keep telephone numbers for
these places handy.
Some of the symptoms of an overdose may include fast heartbeat, dizziness, light-headedness
or fainting, especially when you get up quickly from a sitting or lying position.
This is because your blood pressure is too low.
While you are using Transiderm-Nitro
Things you must do
Tell your doctor if you continue to have angina attacks or if they become more frequent
or severe while you are using Transiderm-Nitro. Keep a record of the number of attacks,

Do not take it to treat any other complaints unless your doctor tells you to.
Things to be careful of
If you are using more than one patch, be careful to remember where you placed it and
when you put it on.

Sometimes keeping track of these patches can be confusing. Be sure to pay particular
attention to where you put each patch and what time each patch should be removed.

If this medicine makes you feel light-headed, dizzy or faint, be careful when getting
up from a sitting or lying position.

and toes to get the blood flowing. When getting out of bed, dangle your legs over
the side for a minute or two before standing up. Use extra care when exercising, driving
or standing for long periods, especially in hot weather.
