Rivastigmine

About rivastigmine

Rivastigmine is used to treat the symptoms of dementia, such as memory loss. It is prescribed for people who have dementia which is associated with Alzheimer's disease or Doença de Parkinson.

Rivastigmine cannot cure dementia, but it can slow down the progression of the symptoms in some people. It works by increasing the level of a natural chemical called acetylcholine. This is a chemical which allows nerve cells in the brain to communicate with each other, and it is known that people with dementia have low levels of it. The symptoms of dementia can be improved by increasing the levels of acetylcholine.

Rivastigmine will be prescribed by a specialist doctor. If you are a caregiver, please read this leaflet on behalf of the person who is receiving rivastigmine.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking rivastigmine it is important that your doctor or pharmacist knows:

• Se você tiver problemas no fígado ou nos rins.

• If you have a heart condition.

• If you have any problems with your breathing, such as asthma or chronic obstructive pulmonary disease (COPD).

• If you have any problems passing urine.

• If you have ever had a stomach (gastric) or duodenal ulcer.

• If you have ever had fits (convulsions or seizures).

• Se você estiver tomando ou usando qualquer outro medicamento. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

• Se você já teve uma reação alérgica a um medicamento.

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about rivastigmine and a full list of side-effects which you may experience from it.

• Your caregiver will help you take your medicine exactly as your doctor has told you. It is usual to be prescribed two doses to take each day. Your dose will be written on the label of your pack to remind you.

• There are several different strengths of rivastigmine capsules and patches available, so make sure the product you have been given is the strength you were expecting. If you are unsure, ask your pharmacist for advice.

• Ideally the capsules or liquid medicine should be taken with, or soon after, your breakfast and your evening meal. Try to take your doses at the same times each day as this will help you to remember to take them.

• If you have been prescribed capsules to take, you should swallow the capsule whole without chewing or crushing it. Taking your doses with a small drink of water may help.

• If you forget to take a dose, take it as soon as you remember, unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

• If you forget to take rivastigmine for several days, talk with your doctor before starting to take it again, as you may need to re-start your treatment on a lower dose.

• If you have been prescribed skin patches, you will be asked to apply one patch each day. Make sure the previous day's patch is removed before you apply a new patch. If the patches cause any irritation to your skin, you should let your doctor know about this.

Taking rivastigmine oral liquid medicine

1. Read the manufacturer's instructions for the medicine you have been given.

2. Open the bottle and remove the oral dosing syringe and bottle adaptor provided.

3. Push the nozzle of the syringe into the bottle adaptor and insert it firmly into the top of the bottle.

4. Turn the bottle upside down.

5. Pull the plunger on the syringe a little way and push back up to get rid of any air bubbles. Then pull the plunger down to withdraw the required amount of medicine. Re-check your dose once you have removed the syringe from the bottle.

6. You can swallow the medicine straight from the syringe, or you can stir it into a glass of water to drink it.

7. When you have finished taking your dose, wipe the outside of the syringe with a tissue. The syringe can be cleaned in warm, soapy water.

Applying rivastigmine (Exelon®) patches

1. Open a packet and remove the patch from inside.

2. Apply the patch to an area of non-hairy skin on your back, upper arm, or chest (but not to your breast area). Press down on the patch with the palm of your hand for around 30 seconds. This will make sure it sticks firmly in place.

3. After 24 hours, remove the patch and do not use the same area of skin to apply another patch to for at least 14 days.

4. Repeat this process each day, removing the previous day's patch before applying a new patch.

5. If you forget to apply a new patch for more than three days, talk with your doctor before applying another patch, as you may need a lower dose.

• When starting your treatment your doctor will give you a small dose and then gradually increase the dose. This allows your doctor to make sure that you have the dose that helps your condition and avoids any unwanted side-effects.

• Your doctor will want to check your progress every few weeks to make sure the dose is right for you and that you are getting benefit from this treatment. Try to keep these regular doctor's appointments.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking rivastigmine. This is because rivastigmine may affect the amount of any anaesthetic you may need.

• If you buy any medicines, always check with a pharmacist that they are safe to take with your other medicines. Some medicines can interfere with the way rivastigmine works.

Along with their useful effects, all medicines can cause unwanted side-effects although not everyone experiences them. The table below lists some of the most common ones associated with rivastigmine. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve over the first few days of taking a new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.
