AllerClear D-12hr (Generic)

Loratadine is an antihistamine which provides relief of seasonal allergy symptoms such as watery and itching eyes, runny nose, and sneezing. Pseudoephedrine is a decongestant which helps relieve a stuffy nose, promotes sinus draining, and improves breathing.

This medication is not recommended for use in children under 12 years of age due to the high amount of pseudoephedrine.
