children’s benadryl contains diphenhydramine and is labeled for use for children aged 6 and older. children’s robitussin is available in a variety of different formulations but may contain guaifenesin dextromethorphan and/or phenylephrine. children’s robitussin is labeled for use for children aged 4 and older (and in some products aged 6 and older). while it is safe to take both the children’s benadryl and children’s robitussin together i would not recommend these products for your child based on her age.
can i give my 2-year-old children's benadryl and robitussin cough syrup together?
