Flonase is a topical, intranasal synthetic corticosteroid. The likelihood of it's causing ADD-like symptoms is miniscule.
Claritin alone, since it is non-drowsy and non-stimulating, *shouldn't* cause ADD syptoms, but the possibility exists. If what your son is taking is Claritin-D, which contains pseudoephedrine, the likelihood of its effecting his ADD symptoms increases. The pseudoephedrine can also worsen his insomnia.
Free~Spirit was correct that allergies themselves can cause inattentive symptoms. It's also common for people to have both.
