Can i take claritin (loratadine) allergy pill every day for 6 months?

Yes: Claritin is a very safe, non-sedating antihistamine. It is effective for treating the symptoms of seasonal allergies. Thus, if you have allergy symptoms for 6 months, it is ok to take that. However, if you have more severe allergies, a nasal steroid spray might be more helpful. I would also recommend you see an allergist to find out what it is that is causing your symptoms.
