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.

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.

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.

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.

You should seek immediate help from a doctor or emergency service of a nearby hospital.

Donepezil does not interfere with the working of indomethacin, but indomethacin individually increases the risk of stomach bleeding when taken for a long time. Therefore, if you experience any symptoms of stomach bleeding, consult your doctor immediately.
