My Mom is having nightmares and diarrhea with the 10mg. Aricept dose?

Up to 5 percent of people taking Aricept 5 mg and 13 percent of people taking Aricept 10 mg daily stopped their medicine because of side effects. Nausea, vomiting, and diarrhea were the most common reasons why people stopped taking Aricept. Side effects tend to be less severe if the dose is slowly increased over a period of several weeks.

Diarrhea was reported in around -- up to 10 percent, Insomnia/nightmares due to perhaps lack of sleep in around -- up to 9 percent, who took Aricept.

However it is recommended to seek medical advice or a change in prescription so that your mother does not have the side effects & the med is well tolerated, hope this helps?

I would say first try the decrease and if this doesnt help yes definantly try something else.

Diarrhea is a side Effect of this Med. but Night mares were not. It possible that she needs to change what she watches on TV , or reads. Dreams could be coming from that or more to the point, is she on other drugs that may have a side Effect of night mares.
