Can you take benefryl within an hour after taking claritin (loratadine)?

Maybe ok, but...: Claritin is a once a day antihistamine, but some forms of it are every-12-hours. Benadryl (diphenhydramine) is an every-6-hours antihistamine, but some forms are every-12-hours. If one takes a normal dose of Claritin and then a normal dose of benadryl (diphenhydramine), (diphenhydramine) it's unproven that there will be any extra benefit, but the person will be drowsy from the benadryl (diphenhydramine). They are mild-mannered meds, so a bad reaction isn't expected.
