How much Claritin for a rat?

Claritin (loratadine) is an antihistamine commonly used for humans, and there is limited research on its safety and dosage for rats. Generally, veterinary guidance should be sought for administering any medication to animals, as dosages can vary widely based on species, weight, and health condition. If you suspect your rat needs antihistamine treatment, consult a veterinarian for proper advice and dosage recommendations.
