A member asked:

Can u take robitussin (guaifenesin) cf during the day and bebedryl at bedtime?

A doctor has provided 1 answer

Yes you can: Robitusson CF is an expectorant and Benadryl (diphenhydramine) is an antihistamine. I see that you are trying to avoid sedative effect during the daytime.You may use claritin, Allegra or zyrtec once at night as alternative.Generally less sedating than benadryl (diphenhydramine).
