I was told by my doctor to take Claritin when I got a bad case of poison ivy. I bought Claritin over the counter, from Walgreens, where the pharmacist assured me that I indeed should take it. It is good for allergies because it contains an Antihistamine. Well, turns out that is also blocks the itching of poison ivy along with the inflamation. It worked great! I took one tablet every day for 10 days. I chose the non-drowsy forumula so I could continue to work while taking the medication. It comes in many different sized boxes. If you are taking this for seasonal allergies, I suggest you buy the larger quantity for better savings. I was very pleased with the results I received from Claritin Non-Drowsy Allergy pills. I would highly recommend this product to everyone!
