Medicine information
Uses & overview
Donepezil 5 mg with Memantine 5 mg is a combination medicine containing two active ingredients that act on different chemical pathways in the brain. It may be prescribed for selected patients with Alzheimer's disease when a healthcare professional considers both medicines appropriate. The exact indication depends on the product's approved uses, the patient's condition, and the prescribing doctor's assessment. Donepezil belongs to a group of medicines called acetylcholinesterase inhibitors. It works by slowing the breakdown of acetylcholine, a chemical messenger involved in memory, learning, and thinking. Memantine is an NMDA receptor antagonist that helps regulate glutamate activity in the brain. These different mechanisms may help manage certain symptoms associated with Alzheimer's disease, although individual responses vary. This combination does not cure Alzheimer's disease or stop its progression. Treatment aims to help manage symptoms and support daily functioning where possible. The prescribing healthcare professional should evaluate the patient's diagnosis, current medicines, medical history, and ability to tolerate both ingredients. Possible side effects include dizziness, headache, nausea, diarrhoea, constipation, confusion, and changes in sleep. Donepezil may also slow the heart rate or contribute to fainting in some patients. Patients with kidney or liver problems, heart rhythm disorders, a history of fainting, or other significant medical conditions should inform their doctor before treatment. The correct dose and schedule depend on the specific product and the patient's circumstances; the two ingredients should not be adjusted independently.
How to use
