Why is this medication prescribed?

Donepezil is prescribed primarily for the treatment of mild to moderate Alzheimer’s disease, a progressive neurological disorder that affects memory, thinking, and behavior. It is an acetylcholinesterase inhibitor, which means it works by increasing the levels of a neurotransmitter called acetylcholine in the brain. Acetylcholine is involved in various cognitive processes, and its deficiency is believed to contribute to the symptoms of Alzheimer’s disease.

Donepezil helps improve cognitive function, such as memory, attention, and language skills, in individuals with Alzheimer’s disease. It does not cure the underlying cause of the disease but can provide symptomatic relief and slow down the progression of cognitive decline in some individuals.

How should this medicine be used?

The dosage and usage instructions for Donepezil can vary depending on the individual’s condition and the doctor’s recommendation. Generally, it is taken orally once a day before bedtime, as it can cause some drowsiness. It is available in different strengths, such as 5 mg and 10 mg tablets. The treatment typically starts with a lower dose, which may be increased gradually over time based on the patient’s response and tolerability.

It is important to follow the prescribed dosage and administration instructions provided by the healthcare professional. If there are any concerns or questions regarding the usage of Donepezil, it is best to consult a doctor or pharmacist for specific guidance.
