Donepezil
Q. Why is Donepezil taken at night?
Donepezil is recommended to be taken before going to bed to reduce gastrointestinal side effects or nausea, which is commonly seen in some patients in the first few weeks of treatment.
Q. Do the gastrointestinal side effects due to Donepezil persist for a long time?
Gastrointestinal side effects may appear during the first few weeks of treatment with Donepezil. This can be minimized by taking Donepezil at bedtime and with food. Generally, these side effects are mild and disappear within a few weeks with continued treatment.
Q. How long does it take for Donepezil to start working?
Within the first month of treatment with Donepezil, you may experience improvement in thinking and remembering (cognitive effect). However, it may take about 12 weeks to see the full benefits.
Q. When should Donepezil be stopped?
Do not stop Donepezil without consulting your doctor. This medicine only helps to control your condition but does not cure it. Therefore, it may take several weeks to show benefits, so do not be discouraged if you do not see an improvement straight away. But, in case your condition starts worsening and you feel that it is no longer helping you, then you should consult a doctor before stopping it.

Donepezil gets removed from the body very slowly. It takes about two weeks or more for Donepezil to be completely removed from the system.
Q. Does Donepezil cause depression?
No, Donepezil does not cause depression. If you are experiencing symptoms, then it could be due to existing Alzheimer’s disease.
Q. What if I take more than the prescribed dose of Donepezil?
Taking more than the recommended dose of Donepezil may cause vomiting, increased sweating or saliva production, slow heartbeat, dizziness, difficulty in breathing, seizures or fits, weakness, and inability to control your bowel motions or passing of urine (incontinence). You should seek immediate help from a doctor or emergency service of a nearby hospital.
Q. I have been taking indomethacin for arthritis. Can I take Donepezil?
