1. What Donepezil Viatris is and what it is used for

Donepezil Viatris contains the active substance donepezil hydrochloride, which belongs to a group of medicines called acetylcholinesterase inhibitors. Donepezil hydrochloride increases levels of a substance (acetylcholine) in the brain involved in memory function by reducing the rate at which this substance is broken down.

It is used to treat the symptoms of dementia in people diagnosed with mild to moderately severe Alzheimer's disease.

The symptoms of the disease include increasing memory loss, increased confusion, and changes in behaviour. As a result, people with Alzheimer's disease have increasing difficulty performing their usual daily activities.

2. What you need to know before taking Donepezil Viatris

Do not take Donepezil Viatris

• If you are allergic to donepezil, to piperidine-derived medicines (your doctor or pharmacist can advise you), or to any of the other ingredients of this medicine (listed in section 6).

• A heart condition (such as irregular or very slow heartbeats, heart failure, myocardial infarction)
• A problem with heart rhythm or heart rate (for example, sick sinus syndrome or other conditions affecting the heart's rhythm or rate). Donepezil may slow the heart rate.
• A heart condition known as "prolongation of the QT interval" or a history of certain abnormal heart rhythms called torsade de pointes, or if someone in your family has "prolongation of the QT interval"
• Low levels of magnesium or potassium in the blood
• Stomach or duodenal (intestinal) ulcers
• Difficulty urinating
• Fainting or seizures: donepezil may potentially cause fainting or seizures. Your doctor will monitor your symptoms.
