Does Claritin (loratadine) work for sun allergy?

Partially. I assume you mean hives or itchy rash from sun exposure (solar urticaria or polymorphous light eruption). Antihistamines can help treat the itch associated with the hives. If rash occurs often, taking an antihistamine daily may help. Sunscreen with uva and uvb blockers may help as well. These may not help other sun-sensitive rashes (eg, with lupus). See an allergist or dermatologist for more info.

Does Claritin (loratadine) work even if you don't have allergies?

Occasionally. It really depends on the nature and severity of your symptoms. Some people feel better after using Claritin for non-allergic issues, largely because antihistamines like Claritin can dry out the nasal passage. This can reduce a runny nose or mild nasal congestion, even if they're non-allergic in nature. Claritin is fairly weak, however, and other non-drowsy options like Allegra can be more helpful.
