A 45-year-old member asked:

Can i take benadryl (diphenhydramine) with allegra?

Yes: You can take them together. If you are sensitive to the sedating effects of antihistamines, you should not take them at the same time. It would be better to take Allegra in the morning or afternoon and then Benadryl (diphenhydramine) in the evening before bed. However, if you don't feel sleepy after taking antihistamines, it would not be harmful to take them together.

Yes, but why: Allegra (fexofenadine) and Benadryl (diphenhydramine) are both antihistamines. Allegra doesn't cross into the brain, so no sedation. Benadryl commonly causes sedation. Typically there is no advantage to taking the 2 together, but also there is no harm at usual doses.

Can allegra work the same as benadryl (diphenhydramine)?

Antihistamines: Both are antihistamines. Benadryl (diphenhydramine) works for a maximum of 6 hours, Allegra works for 24. Allegra is non drowsy but Benadryl (diphenhydramine) is very sedating.

Not a good idea.: Without precise close coordination with a pediatric allergist or knowledgeable pediatrician, taking Allegra and Benadryl (diphenhydramine) together is probably not a good idea. If your child's allergies are that severe, maybe you should address this issue with your pediatrician. Perhaps allergy testing is in order to identify the source of such overwhelming allergy symptoms that requires double dosing with 2 meds.

Yes: Antihistamine is safe even with 4x the average daily dose. The major side effects would be dry mouth and drowsiness ( the latter much less common if one uses the non-sedating type).
