Dimetapp and Allegra have no drug interactions that I can find, however - there are multiple versions of Dimetapp and Allegra that have different ingredients.

I would advise contacting a local pharmacist and asking them about the specific version of Allegra you have, and the specific version of Dimetapp you have. You do not want to risk the possibility of overdose.
