Dr. Andy :

Welcome to JustAnswer!

Jake may be having an allergic reaction to the drug.

Giving benadryl may help, but ultimately, he may need to get into a vet for better supportive treatment including a steroid to calm the inflammation and itch.

Benadryl can be given at a dose of 1mg per pound of body weight. Keep in mind, Benadryl tablets and liquids come in different sizes. So, an approximately 25 pound dog can get a full 25mg tablet or a half of a 50mg tablet. I usually avoid the liquid Benadryl in larger dogs (you would have to give too much of it). You can give Benadryl every 8-12 hours.

Benadryl can also be a little bit sedating, so that might help some as well.

Make sure to inform your vet what happened, so they can also recommend a different flea product for the future.

Hope that info helps

I don't have any benadryl on hand, so I'll have to wait. I am surprised because I have used Frontline on Jake for years and he has never had a reaction, why would this happen now?

Dr. Andy :

Well, we don't know for sure it is the cause, but it can happen.

Just like a vaccine. I have seen pets 10 years old that have had a dozen vaccines, and then suddenly have a reaction.

JACUSTOMER-bxw8i3o3- :

Ok, I'll take him to our vet in the morning. Is there anything I should watch for in the meantime? I'm pretty worried about him, and like I said, neither of us are going to get much sleep...

Dr. Andy :

Monitor for:

- injury from incessant scratching
- vomiting
- hives like reaction on skin (bumps all over skin)
- facial swelling

Good Luck

JACUSTOMER-bxw8i3o3- :

So far he doesn't have any of the above, but he's whining now, and literally itching almost non-stop. Thanks for the info.

Last thing, this probably can wait till the morning, right? I mean if none of the other symptoms come up? And if they do, should I call an emergency vet?

Dr. Andy :

I do feel it is worth an ER vet now. Non-stop itching is quite bad and it will really aggravate him.

JACUSTOMER-bxw8i3o3- :

It's a problem because I live in Mexico and it's a remote area and not really safe to drive at night, that's why I'm hesitant. So if he doesn't have other symptoms, I want to wait til the morning. But if he's at risk, I need to do what I can.

Dr. Andy :

Safety first. Period

JACUSTOMER-bxw8i3o3- :

Yeah, you're right. Thanks for your advice. We'll be ok.

Dr. Andy :

Your very welcome. Good Luck

JACUSTOMER-bxw8i3o3- :

He actually just fell asleep under my chair while I'm writing this, so it looks like we'll be fine to wait til the morning. I'll keep an eye on him for the other symptoms, thanks again. Have a good night.

Dr. Andy :

Good night
