1. What Alzakt is and what it is used for

The active substance of Alzakt 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, rivastigmine allows levels of acetylcholine to be increased in the brain, helping to reduce the symptoms of Alzheimer’s disease.

Alzakt 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 Alzakt
Do not use Alzakt
  • if you are allergic to rivastigmine (the active substance in Alzakt) 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 Alzakt transdermal patches.

Warnings and precautions

Talk to your doctor before using Alzakt

  • 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 Alzakt in the paediatric population in the treatment of Alzheimer’s disease.

Other medicines and Alzakt

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

Alzakt 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).

Alzakt 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 Alzakt, tell your doctor that you are using it because it may exaggerate the effects of some muscle relaxants during anaesthesia.

Caution when Alzakt 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 Alzakt 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 Alzakt must be assessed against the possible effects on your unborn child. Alzakt should not be used during pregnancy unless clearly necessary.

You should not breast-feed during treatment with Alzakt.

Driving and using machines

Your doctor will tell you whether your illness allows you to drive vehicles and use machines safely. Alzakt 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 Alzakt

Always use Alzakt 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 Alzakt transdermal patch is most suitable for you.

  • Treatment usually starts with Alzakt 4.6 mg/24 h.
  • The recommended usual daily dose is Alzakt 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 Alzakt transdermal 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 Alzakt 4.6 mg/24 h.

Alzakt can be used with food, drink and alcohol.

Where to apply Alzakt 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 Alzakt transdermal patch

Alzakt patches are thin, self-adhesive patches. Each patch is sealed in a sachet. Open the sachet only right before you want to apply a new patch and remove it.

For patients starting treatment for the first time and for patients restarting the treatment again after an interruption, please begin with the second picture.

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

  • Each patch is sealed in its own individual sachet.

Only open the sachet when you are ready to apply the patch. Cut the sachet at the dotted line with scissors and remove the patch from the sachet.

The patch can most easily be removed when the sachet is cut on two sides.

  • The self-adhesive side of the patch is covered by a protective liner.
    Peel off one half of the protective liner and do not touch the sticky part of the patch with your fingers.
  • Put the sticky side of the patch on the upper or lower back, upper arm or chest and then peel off the second half 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 all the edges stick well.

As a reminder you can write the day of the week on the patch with a fine ball point pen for example.

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

If you use more Alzakt 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 rivastigmine 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 Alzakt

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 Alzakt

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.
