Chlorpheniramine is a type of antihistamine which is sometimes used to treat the symptoms of allergies and itching in dogs. It is a first generation H1 antagonist which acts similar to diphenhydramine, and like diphenhydramine it does cause drowsiness, but to a slightly lesser degree. This makes it inferior for sedation, but useful when you want to relieve the symptoms of allergies without causing sleepiness, or when lighter sedation is required.
It has a good safety profile when used in healthy dogs.
Note: Even though chlorpheniramine is available over-the-counter, it could be unsafe for dogs with certain medical conditions or who are taking certain medication. Always consult with a vet before use.
The typical dosage of chlorpheniramine for treating dogs is 4 – 8 mg every 8 to 12 hours, with a maximum dose of 1.1 mg/lb. Some vets recommend dosing by the dog’s weight at 0.9 – 1.7 mg/lb every 8 to 12 hours, but many agree on the upper limit of 1.1 mg/lb. Slightly lower amounts of around 0.5 mg/lb (up to 7 mg every 8 hours) could be used for sedation
