Should not be combined
Welcome to HCM.
I am Dr Anshul Varshney. I have read your query in detail. I understand your concern.
First of all if you have some stomach problem , and you are taking benadryl
for it and want to take Zolpedem also for that only , I must tell you these drugs are not indicated for treatment of any stomach ailments.
I would be glad to help you regarding your stomach ailments. So please give us details about that .
As far as your query is concerned. These drugs should not be combined as Benadryl causes sedation and Zolpidem
also induces sleep.
So combining them can cause excessive sedation , drowsiness
, respiratory depression
and chances of aspiration into lungs due to excessive sedation.
So avoid combining them.
I hope I am able to answer your query. If you have any further query you may please ask us.
If you wish you may also discuss with us about your stomach problem.
