Can i take alka seltzer plus cold and benadryl (diphenhydramine) at the same time?
A doctor has provided 1 answer
Cough medicines: Alka seltzer plus has i believe Acetaminophen and phenylephrine in it which is a decongestant but not an antihistamine. It also has dextromethorphan cough suppressant. Benadryl (diphenhydramine) is an antihistamine. So yes you can take them together of added effect on sinus and nasal congestion. Benadryl (diphenhydramine) can make you sleepy.
