McKesson's allergy relief loratadine tablets are just what you need during allergy season. The tablets help relieve sneezing, runny nose, and the itching and watering of eyes due to upper respiratory allergies. This antihistamine also helps treat itching and redness from hives. However, please keep in mind that it does not prevent hives. Each dosage is individually packaged in a dispenser box for your convenience. A single tablet works for 24 hours to help treat allergy symptoms.
