Hi Stuart,

I'm Dr. Bridget. Thanks for your patience while I prepared your answer.

Yes, there are some interactions:

1) Donepezil, Trospium and Vistaril: Trospium and Vistaril may reduce the effectiveness of Donepezil.

2) Donepezil, Vistaril and Venlafaxine: combination may increase the risk of a type of heart arrythmia

3) Vistaril and Loratadine: may increase the risk of drowsiness, dry mouth, constipation, urinary retention

Please feel free to ask any further questions...I am standing by:)

I feel better already! Thank you.

ElanorTracy, CA

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.

JulieLockesburg, AR

You have been more help than you know. I seriously don't know what my sisters situation would be today if you had not gone above and beyond just answering my questions.

John and StefanieTucson, AZ

I have been dealing with an extremely serious health crisis for over three years, and one your physicians asked me more questions, gave me more answers and encouragement than a dozen different doctors who have been treating me!!
