Can Acatar care kids, Nasonex and Rhinoargent be used at the same time? What should be the time interval between them?

Yes, you can use Acatar care kids in a person who is taking Nasonex and Rhinoargent. There should be a time interval between preparations, e.g. Rhinoargent, administered at least 15 minutes before Nasonex, and then another 15 minutes and Acatar. Acatar should be administered last, because it constricts blood vessels in the nasal mucosa, which will limit the bioavailability of other drugs.
