Adults and those over 12 years of age can take anywhere from 25 to 50 mg every 4-6 hours. The size of Benadryl doses is directly determined by the size and weight of the patient.

The average dose for a child is between 12.5-25 mg every 4-6 hours. This can be increased as they grow. The minimum effective dose of Benadryl is 12.5 mg or ml in one day depending on whether you are taking a capsule or liquid form. The maximum intake is 50 mg for a full sized adult. Children should not take more than 25 mg. The topical version of Benadryl can be applied as needed throughout the day.
