In brief: Not necessary

Both Claritin (loratadine) and zyrtec are considered new generation antihistamines and have the same effects.
If a person accidentally took these at the same time, there is likely no adverse effect, but there is really no need to take both for treatment of symptoms. If symptoms of allergies are not controlled, see an allergist for a better treatment plan.
