Customer Question

My 4yr old female presented with swelling of the nose and ears last night, and pawing at her face, as though it itches. I think it is an allergic reaction and want to try Benadryl but she is pregnant and I want to make sure it is safe. She is due around February 5 or so.

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

Now her being pregnant does make this a tricky situation. This is because there are no antihistamine is licensed as safe for pregnancy in dogs. In regards ***** ***** this is considered a class B drug as related to pregnancy. This means we usually will avoid its use but a single dose usually is safe and low risk to the pups.

That said, in regards ***** ***** lowest risk, Chlorphenamine (given at a dose of 4mg up to every 8 hours) is considered safest to use during human pregnancy as long as not giving close to labor. So, as this is a situation we'd need to extrapolate from human medication that would be our main choice here. Otherwise, Loratadine (5mg every 24 hours) and Cetirizine (1mg per kilogram of her weight ever 12-24 hours) would be preferable over Benadryl. And all of these are OTC at most pharmacies and grocery stores. So, those would be out options here with her allergic reaction. Though we'd of course want to follow up with her vet if there are any suspect bites causing this or she doesn't settle.

Please take care,

Dr. B.
