What Minitran is used for

These patches are used to help prevent attacks of angina (chest pain).

The active ingredient, glyceryl trinitrate, belongs to a group of medicines called nitrates.

When a Minitran patch is placed on the skin, glyceryl trinitrate passes slowly through the skin and into the blood stream. Glyceryl trinitrate works by widening blood vessels, letting more blood and oxygen reach the heart.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

How to use Minitran

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

To use Minitran take the following steps:

  1. Start at the notched corner.
  2. Tear pouch along the dotted line.
  3. Bend the patch so that the tab on the liner pops up.
  4. Hold the tab to peel off the liner.
  5. Apply sticky side of the patch to the upper arm or chest.
  6. Remove and discard the other piece of liner.
  7. Press patch firmly into place.

How much to use

The usual dose of Minitran is one patch applied every day. Your doctor will prescribe the correct dose for you.

When to use it

Apply a new patch at the same time every day. Each patch is usually worn for 12 to 16 hours each day, or for as long as your doctor tells you.

How to use Minitran

Minitran patches can be placed on the chest, shoulder, upper arm or back.

Do not place Minitran patches on your forearm or lower leg.

Always put your patch on a different area of skin each day. If you use the same area too much you may get a rash.

Minitran patches should not be placed on broken skin such as cuts or grazes.

You should place the patch on a hairless area of skin. If the area of skin is hairy, clip or shave the hair off.

The skin should be clean and dry before sticking a Minitran patch on. This will make the patch stick properly.

Do not use dusting powder or any greasy substances, eg. ointments or creams, on the skin before applying the patch.

How long to use it

Continue using your medicine for as long as your doctor tells you.

This medicine helps control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.

If you forget to use Minitran

If you forget to use Minitran, apply the patch as soon as you remember. However, if it is more than 4 hours after you were due to use the patch, skip the patch that you missed.

Apply the next patch at the normal time. Never apply extra patches to make up for the patch you have missed.

If you use too much Minitran

Glyceryl trinitrate overdose is unlikely when using Minitran patches.

If accidental overdose does occur, remove the patch and contact your doctor or go to Accident and Emergency at your nearest hospital.

While you are using Minitran

Things you must do

Minitran patches are intended to prevent angina attacks.

If you do have an attack of chest pain when using Minitran, you should use under-the-tongue glyceryl trinitrate tablets or a similar medication as instructed by your doctor.

Tell your doctor if you continue to have angina attacks or if they become more frequent while you are using Minitran.

Ask your doctor if it is safe to drink alcohol while you are using Minitran.

You can bathe, shower and swim as normal when wearing a Minitran patch.

If a patch does not stick or falls off, simply use a new patch on a different area of skin.

Do not re-use a patch once it has been removed from the skin.

Things you must not do

Do not stop using Minitran abruptly. If you are to stop using Minitran, your doctor will gradually reduce the dose over 4 to 6 weeks before you completely stop using it.

Things to be careful of

Minitran patches may lower your blood pressure and make you feel dizzy, particularly when changing position suddenly.

You should be especially careful if you are driving or operating machinery. This medicine may cause dizziness or light-headedness in some people.

If you have any of these symptoms, do not drive, operate machinery or do anything that could be dangerous.

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
