Prometax 13.3 mg/24 h transdermal patch – patient leaflet, side effects, dosage

1. What Prometax is and what it is used for

The active substance of Prometax is rivastigmine.

Rivastigmine belongs to a class of substances called cholinesterase inhibitors. In patients with Alzheimer’s dementia, certain nerve cells die in the brain, resulting in low levels of the neurotransmitter acetylcholine (a substance that allows nerve cells to communicate with each other). Rivastigmine works by blocking the enzymes that break down acetylcholine: acetylcholinesterase and butyrylcholinesterase. By blocking these enzymes, Prometax allows levels of acetylcholine to be increased in the brain, helping to reduce the symptoms of Alzheimer’s disease.

Prometax is used for the treatment of adult patients with mild to moderately severe Alzheimer’s dementia, a progressive brain disorder that gradually affects memory, intellectual ability and behaviour.

2. What you need to know before you use Prometax

Do not use Prometax

• if you are allergic to rivastigmine (the active substance in Prometax) or any of the other ingredients of this medicine (listed in section 6).
• if you have ever had an allergic reaction to a similar type of medicine (carbamate derivatives).
• if you have a skin reaction spreading beyond the patch size, if there is a more intense local reaction (such as blisters, increasing skin inflammation, swelling) and if it does not improve within 48 hours after removal of the transdermal patch.

If this applies to you, tell your doctor and do not apply Prometax transdermal patches.

Warnings and precautions

Talk to your doctor before using Prometax:

• if you have, or have ever had, a heart condition such as an irregular or slow heartbeat, QTc prolongation, a family history of QTc prolongation, torsade de pointes, or have a low blood level of potassium or magnesium.
• if you have, or have ever had, an active stomach ulcer.
• if you have, or have ever had, difficulties in passing urine.
• if you have, or have ever had, seizures.
• if you have, or have ever had, asthma or a severe respiratory disease.
• if you suffer from trembling.
• if you have a low body weight.
• if you have gastrointestinal reactions such as feeling sick (nausea), being sick (vomiting) and diarrhoea. You may become dehydrated (losing too much fluid) if vomiting or diarrhoea are prolonged.
• if you have impaired liver function.

If any of these apply to you, your doctor may need to monitor you more closely while you are on this medicine.

If you have not applied a patch for more than three days, do not apply the next one before you have talked to your doctor.

Children and adolescents

There is no relevant use of Prometax in the paediatric population in the treatment of Alzheimer’s disease.

Other medicines and Prometax

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Prometax might interfere with anticholinergic medicines some of which are medicines used to relieve stomach cramps or spasms (e.g. dicyclomine), to treat Parkinson’s disease (e.g. amantadine) or to prevent motion sickness (e.g. diphenhydramine, scopolamine, or meclizine).

Prometax Patch should not be given at the same time as metoclopramide (a medicine used to relieve or prevent nausea and vomiting). Taking the two medicines together could cause problems such as stiff limbs and trembling hands.

If you have to undergo surgery whilst using Prometax transdermal patches, tell your doctor that you are using them because they may exaggerate the effects of some muscle relaxants during anaesthesia.

Caution when Prometax Patch is given together with beta-blockers (medicines such as atenolol used to treat hypertension, angina, and other heart conditions). Taking the two medicines together could cause problems such as slowing of the heartbeat (bradycardia) leading to fainting or loss of consciousness.

Caution when Prometax is taken together with other medicines that can affect your heart rhythm or the electrical system of your heart (QT prolongation).

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

If you are pregnant, the benefits of using Prometax must be assessed against the possible effects on your unborn child. Prometax should not be used during pregnancy unless clearly necessary.

You should not breast-feed during treatment with Prometax transdermal patches.

Caution when Prometax is taken together with other medicines that can affect your heart rhythm or the electrical system of your heart (QT prolongation).

Driving and using machines

Your doctor will tell you whether your illness allows you to drive vehicles and use machines safely. Prometax transdermal patches may cause fainting or severe confusion. If you feel faint or confused do not drive, use machines or perform any other tasks that require your attention.

3. How to use Prometax

Always use Prometax transdermal patches exactly as your doctor has told you. Check with your doctor, pharmacist or nurse if you are not sure.

IMPORTANT:

• Take off the previous patch before putting ONE new patch on.
• Only one patch per day.
• Do not cut the patch into pieces.
• Press the patch firmly in place for at least 30 seconds using the palm of the hand.

How to start treatment

Your doctor will tell you which Prometax transdermal patch is most suitable for you.

• Treatment usually starts with Prometax 4.6 mg/24 h.
• The recommended usual daily dose is Prometax 9.5 mg/24 h. If well tolerated, the treating physician may consider increasing the dose to 13.3 mg/24 h.
• Only wear one Prometax patch at a time and replace the patch with a new one after 24 hours. During the course of the treatment your doctor may adjust the dose to suit your individual needs.

If you have not applied a patch for more than three days, do not apply the next one before you have talked to your doctor. Transdermal patch treatment can be resumed at the same dose if treatment is not interrupted for more than three days. Otherwise your doctor will restart your treatment on Prometax 4.6 mg/24 h.

Prometax can be used with food, drink and alcohol.

Where to apply your Prometax transdermal patch

• Before you apply a patch, make sure that your skin is clean, dry and hairless, free of any powder, oil, moisturiser or lotion that could keep the patch from sticking to your skin properly, free of cuts, rashes and/or irritations.
• Carefully remove any existing patch before putting on a new one. Having multiple patches on your body could expose you to an excessive amount of this medicine which could be potentially dangerous.

• Apply ONE patch per day to ONLY ONE of the possible locations shown in the following diagrams:

  • left upper arm or right upper arm
  • left upper chest or right upper chest (avoid breast)
  • left upper back or right upper back
  • left lower back or right lower back

Every 24 hours take off the previous patch before putting

ONE new patch on to ONLY ONE of the following possible locations.

When changing the patch, you must remove the previous day’s patch before you apply the new one to a different location of skin each time (for example on the right side of your body one day, then on the left side the next day, and on your upper body one day, then on your lower body the next day). Do not apply a new patch to the same skin area twice within 14 days.

How to apply your Prometax transdermal patch

Prometax patches are thin, opaque, plastic patches that stick to the skin. Each patch is sealed in a sachet that protects it until you are ready to put it on. Do not open the sachet or remove a patch until just before you apply it.

Carefully remove the existing patch before putting on a new one.

For patients starting treatment for the first time and for patients

restarting Prometax after treatment interruption, please begin with

the second picture.

• Each patch is sealed in its own protective sachet.

  You should only open the sachet when you are ready to

  apply the patch.

  Cut the sachet along the dotted line with scissors and

  remove the patch from the sachet.

• A protective liner covers the sticky side of the patch.

  Peel off one side of the protective liner and do not touch the

  sticky part of the patch with the fingers.

• Put the sticky side of the patch on the upper or lower back,

  upper arm or chest and then peel off the second side of the

  protective liner.

• Then press the patch firmly in place for at least 30 seconds

  using the palm of the hand to make sure that the edges stick

  well.

If it helps you, you may write, for example, the day of the week, on the patch with a thin ball point pen.

The patch should be worn continuously until it is time to replace it with a new one. You may wish to experiment with different locations when applying a new patch, to find ones that are most comfortable for you and where clothing will not rub on the patch.

How to remove your Prometax transdermal patch

Gently pull at one edge of the patch to remove it slowly from the skin. In case the adhesive residue is left over on your skin, gently soak the area with warm water and mild soap or use baby oil to remove it. Alcohol or other dissolving liquids (nail polish remover or other solvents) should not be used.

You should wash your hands with soap and water after removing the patch. In case of contact with eyes or if the eyes become red after handling the patch, rinse immediately with plenty of water and seek medical advice if symptoms do not resolve.

Can you wear your Prometax transdermal patch when you are bathing, swimming, or in the sun?

• Bathing, swimming or showering should not affect the patch. Make sure the patch does not loosen during these activities.

• Do not expose the patch to any external heat sources (e.g. excessive sunlight, saunas, solarium)

  for long periods of time.

What to do if a patch falls off

If a patch falls off, apply a new one for the rest of the day, then replace it at the same time as usual the next day.

When and for how long to apply your Prometax transdermal patch

• To benefit from treatment, you must apply a new patch every day, preferably at the same time of day.
• Only wear one Prometax patch at a time and replace the patch with a new one after 24 hours.

If you use more Prometax than you should

If you accidentally apply more than one patch, remove all the patches from your skin, then inform your doctor that you have accidentally applied more than one patch. You may require medical attention. Some people who have accidentally taken too much Prometax have experienced feeling sick (nausea), being sick (vomiting), diarrhoea, high blood pressure and hallucinations. Slow heartbeat and fainting may also occur.

If you forget to use Prometax

If you find you have forgotten to apply a patch, apply one immediately. You may apply the next patch at the usual time the next day. Do not apply two patches to make up for the one that you missed.

If you stop using Prometax

Tell your doctor or pharmacist if you stop using the patch.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
