The 
serum levels of adinazolam, 
alprazolam, chlordiazepoxide, clobazam, clorazepate, 
diazepam, flurazepam, nitrazepam, 
triazolam, 
zaleplon, 
zolpidem (and probably halazepam and prazepam) are raised by 
cimetidine, but normally this appears to be of little or no 
clinical importance, and only the occasional patient may experience an 
 increase in effects (sedation). Clotiazepam, 
lorazepam, lormetazepam, 
oxazepam and 
temazepam are not normally affected by 
cimetidine. Famotidine, 
nizatidine and ranitidine do not interact with most benzodiazepines, except possibly 
triazolam. The picture with 
midazolam is somewhat confused. 
 In general no clinically significant interaction occurs, but note that individual patients may rarely experience increased sedation.
