Flexeril/Ambien. Some added sedation, otherwise ok.
Caution. It will cause additive central nervous system depression and psychomotor impairment which means you definitely should not drive while taking both medications. If you have any pulmonary conditions like sleep apnea, definitely not. These patients can stop breathing with sedatives and die. How about using ambien (zolpidem) to sleep and save flexeril for daytime use?
Yes. But not recommended as they may potentiate the effects. So be careful.
