Patient leaflet - Prometax 1.5 mg hard capsules
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 or dementia due to Parkinson’s disease, 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 and dementia associated with Parkinson’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. The capsules and oral solution can also be used for the treatment of dementia in adult patients with Parkinson’s disease.
2. What you need to know before you take Prometax
Do not take 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 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 take Prometax.
Warnings and precautions
Talk to your doctor before taking 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 severe respiratory disease.
- if you have, or have ever had impaired kidney function.
- if you have, or have ever had, impaired liver function.
- 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 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 taken Prometax for more than three days, do not take the next dose until 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 should not be given at the same time as other medicines with similar effects to Prometax. Prometax might interfere with anticholinergic medicines (medicines used to relieve stomach cramps or spasms, to treat Parkinson’s disease or to prevent travel sickness).
Prometax 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 taking Prometax, tell your doctor before you are given any anaesthetics, because Prometax may exaggerate the effects of some muscle relaxants during anaesthesia.
Caution when Prometax is taken 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.
Driving and using machines
Your doctor will tell you whether your illness allows you to drive vehicles and use machines safely. Prometax may cause dizziness and somnolence, mainly at the start of treatment or when increasing the dose. If you feel dizzy or sleepy, do not drive, use machines or perform any tasks that require your attention.

Slow heartbeat and fainting may also occur.
