There are a lot of misconceptions of what medications are "drying" in terms of anti-histamines. Some anti-histamines do have anti-cholinergic affects, which can really affect a CFer. Those anti-histamines include diphenhydramine (Benedryl) to a lesser extent, Zyrtec.
Claritin and Allegra both do not have anti-cholinergic affects and therefore do not dry CF secretions.
