Aricept is an enzyme blocker that is used to treat confusion in the patients of Alzheimer’s disease. Although the medicine doesn’t help in the progression of the disease, it somehow lowers down the forgetfulness and confusion caused by Alzheimer’s disease.

It functions to block the neurotransmitter production in the brain causing the patient to feel a bit less disoriented.

There are three variants of the tablets, with potency of 5mg, 10 mg and 23 mg.

The medicine can be prescribed in combination with other medications to cure the symptoms of Alzheimer’s disease.


Aricept comes in tablet form that should not be crushed before swallowing. Crushing a tablet can cause side effects.

The usual dosage is one 5 mg tablet per day, usually in the evening. However, if there is an indication of sleeplessness in the patient, the medicine can be altered for day time dose.

The maximum dosage per day for patients with severe symptoms is 23 mg per day.

The dose should not be altered directly to 23 mg per day until and unless the previous 10 mg dose is continued at least for three months.

The medicine can be taken with or without food as per the doctor’s instructions.
