Benadryl Ultratabs is a medication that helps relieve symptoms from hay fever, other upper respiratory allergies, and the common cold, such as a runny nose, sneezing, and itchy, watery eyes. It works by blocking certain natural substances in the body that cause these allergy symptoms. For adults and children aged 12 and over, the usual starting dose is 1 to 2 tablets taken every 4 to 6 hours, but you should not take more than 6 tablets in a day. It's important to avoid using this medication to make a child sleepy and to be cautious if you are taking sedatives or tranquilizers, as they can increase drowsiness.
