My husband went to the doctor today for severe cough thats been going on for two weeks Dr. said he must have a virus but took no samples of anything hes coughing severely he took a Zyrtec D but its not helping can he take NyQuil or another cough suppressant along with Zyrtec-D
Yes your husband can take NyQuil in addition to the Zyrtec. I personally would recommend delay as a cough suppressant as it works for 12 hours and may give him the better relief for his cough.
