Can you take NyQuil with cheratussin ac?

No. My daughter was prescribed Cheratussin. She took it with the Ambien and had extreme phsycodelic events. Her hands were misshapen she saw bugs on the wall, people who weren't there, lights that were not on. She also had trouble breathing. My suggestion would be if you do mix the two, use caution. I would not rest until I knew she was going to be ok
