I give my cat benadryl, and he foamed at the mouth/drooled ?

My cat has an upper respiratory infection, and the vet put him on antibiotics and said that I could give him 1/2 of a benadryl to help near the congestion, but when I gave it to him, he foamed and drooled for about 20 minutes. Is this normal? he's acting ok presently, it just freaked me out.
I was just wondering whether anyone else had this happen?
Benadryl is available in 12.5 mg, 25 mg and 50 mg tablets. It is also available as a 12.5 mg/ml suspension.
In cats, benadryl is dosed at 0.25 to 0.5 mg per pound (0.5 to 1 mg/kg) every 12 hours but it have a bitter taste and can cause profuse, yet interim, drooling. Check the dosage that you are giving him.
The duration of administration depends on the condition being treated, response to the medication and the development of any adverse effects. Be solid to complete the prescription unless specifically directed by your veterinarian. Even if your pet feels better, the entire treatment plan should be completed to prevent relapse.
It's middle-of-the-road, but gross -- I don't know why they do it, but my cat got the same kind of infection in the order of a month ago!

My vet gave her an injection the day she was brought contained by, and he also put her on half a Zeniquin a day, and suggested Baby Benadryl (liquid)at night -- squeezed down her throat next to a syringe, which I did for about five days. She did the mouth foaming, too.

I also had to keep her within the bathroom away from the other cats so they wouldn't catch what she had. (I don't know how she get it, because Smokey is a totally inside cat) I think she thought she was being punished, and she go on a hunger strike.

I was at my wit's end trying to find something Smokey would put away. Horrible week. Finally I got her to eat tuna and water, and by later she was looking and breathing better, so I let her out with the other cats again, and she go back to eating.

Daffy cat!
My cats other drool when giving them liquid medication via syringe. My vet said that this normal and suggested mixing their dosage into their food so that they don't spit/drool it all up. I would speech to your vet though.
First of adjectives, I don't think the "vet" that answered you question is a vet at all! Although it IS strange for a vet to prescribe Benadryl for congestion, it's often used for allergic reactions in animals.
Cats recurrently foam at the mouth when they've eaten something that tastes bad to them. Medicines habitually fit that description. If I were you I'd skip the Benadryl since it's obviously stressing your cat.
A cool mist vaporizer is a better choice than steam. It actually help shrink airways the same way ice help reduce swelling.
Quite honestly, unless your cat is actually having difficulty breathing (wheezing, jerk movements of the chest, blowing nose bubbles, etc.) your best bet is just staying with the antibiotics & making certain your cat has a comfy, draft free place to rest.
Sounds like your kitty is one of the lucky ones that has someone that care a lot about him : )
I'm a vet and I've never heard of ANYONE giving their cat Benadryl as medication for congestion. Benadryl is used to treat congestion in humans only, and should never be used on animals.

The antibiotics will transport about 24 hours to start working to full effect, so in the meantime, just fashion sure he has plenty of fresh water and some food. Keep him contained by a warm, dry spot. Don't let him outside whether possible.

If he sounds really wheezy, you can take him into the bathroom with you while you are having a shower. Don't turn the adherent on and the steam should help clear his airways out a little. Don't get him drizzling because this could stress him out, making him breath faster and worsening the situation.

If he doesn't get any better after a few days, I would take him back to another vet clinic for a moment opinion.

Good luck with your kitty =D
Actually, "vet", it's very common to dispense animals Benadryl because of the mild sedative effects. It is recommended frequently by vets!

Some animals enjoy odd reactions, the same opening some individuals react to Nyquil. I've heard and seen this previously. You should always do a check up with your vet to make certain the reaction is not abnormal though.

He should be fine. Hope he gets better soon!
Sorry, miss manda, if you be a real vet, you would know that benedryl is prescribed for allergic reactions regularly. Not so much for congestion, but it is safe to use within animals.
The foaming is because benedryl is bitter, and if you didn't get it straight down his throat, he will foam horribly. Especially since you had to break the pill, exposing the lightly cooked medicine from the coating.
Could be an allergic reaction. If I were you, I'd wait and achieve her checked again before I did it again. Or at least call your vet and explain what happen.
Answers:    Oral diphenhydramine(main ingredient in benadryl) is bitter, and can incentive drooling in a cat, it's normal.
My cat has be on it for years due to allergies..common knowledge to a real vet...
