  4. 1. What APOZYL is and what it is used for

APOZYL contains the active substance donepezil hydrochloride. APOZYL (donepezil hydrochloride) belongs to a group of medicines called

acetylcholinesterase inhibitors. Donepezil increases the levels of a substance (acetylcholine) in the brain involved in memory function by slowing down the breakdown of acetylcholine.

It is used to treat the symptoms of dementia in people diagnosed as having mild and moderately severe Alzheimer’s disease. The symptoms include increasing memory loss, confusion and behavioural changes. As a result, sufferers of Alzheimer’s disease find it more and more difficult to carry out their normal daily activities.

APOZYL is for use in adult patients only.

2. What you need to know before you take APOZYL

Do NOT take APOZYL

if you are allergic to donepezil hydrochloride, or to piperidine derivatives, or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before taking APOZYL if you have or have had:

stomach or duodenal ulcers

seizures (fits) or convulsions

a heart condition (such as irregular or very slow heart beat, heart failure, myocardial infraction) a heart condition called ‘prolonged QT interval’ or a history of certain abnormal heart rhythms called Torsade de Pointes or if anyone in your family has ‘prolonged QT intervals’

low level of magnesium or potassium in your blood

asthma or other long term lung disease liver problems or hepatitis

difficulty passing urine or mild kidney disease

Also tell your doctor if you are pregnant or think you might be pregnant.

Children and adolescents

APOZYL is not recommended for use in children and adolescents (younger than 18 years of age).

Other medicines and APOZYL

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines that your doctor has not prescribed for you but which you have bought yourself from a chemist/pharmacist. It also applies to medicines you may take some time in the future if you continue to take APOZYL. This is because these medicines may weaken or strengthen the effects of APOZYL.

In particular it is important to tell your doctor if you are taking any of the following types of medicines: medicines for heart rhythm problems e.g. amiodarone, sotalol

medicines for depression e.g. citalopram, escitalopram, amitriptyline, fluoxetine medicines for psychosis e.g. pimozide, sertindole, ziprasidone

medicines for bacterial infections e.g. clarithromycin, erythromycin, levofloxacin, moxifloxacin, rifampicin

anti-fungal medicine e.g. ketoconazole other Alzheimer’s disease medicines, e.g. galantamine

Dimension: 180 x 420 mm

Date: 09 Nov 2023

pain killers or treatment for arthritis e.g. aspirin, non-steroidal anti-inflammatory (NSAID) drugs such as ibuprofen, or diclofenac sodium anticholinergics medicines, e.g. tolterodine anticonvulsants e.g. phenytoin, carbamazepine medication for a heart condition e.g. quinidine, beta-blockers (propranolol and atenolol) muscle relaxants e.g. diazepam, succinylcholine general anaesthetic

medicines obtained without a prescription e.g. herbal remedies

If you are going to have an operation that requires you to have a general anaesthetic, you should tell your doctor and the anaesthetist that you are taking APOZYL. This is because your medicine may affect the amount of anaesthetic needed.

APOZYL can be used in patients with kidney disease or mild to moderate liver disease. Tell your doctor first if you have kidney or liver disease. Patients with severe liver disease should not take APOZYL.

Tell your doctor or pharmacist the name of your caregiver. Your caregiver will help you to take your medicine as it is prescribed.

APOZYL with food, drink and alcohol

Food will not influence the effect of APOZYL.

APOZYL should not be taken with alcohol because alcohol may change its effect.

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 any medicine.

APOZYL should not be used while breast-feeding.

Driving and using machines

Alzheimer’s disease may impair your ability to drive or operate machinery and you must not perform these activities unless your doctor tells you that it is safe to do so.

Also, your medicine can cause tiredness, dizziness and muscle cramp. If you experience any of these effects, you must not drive or operate machinery.

APOZYL 5 mg orodispersible tablets contains 5 mg of aspartame (E951) and APOZYL 10 mg orodispersible tablets contains 10 mg of aspartame (E951). Aspartame is a source of phenylalanine.
