Q: Benedryl dosage

Several months ago my vet told me to give my cat Benedryl when allergies get bad, I can't remember the dose but think it was 1/2 mg per pound. I called the clinic to ask the vet and the receptionist informed me it is 1 mg per pound, so a 50 pound dog would be 50 mg. Well I have a CAT. Is the dosage the same?! Once or twice a day?
Thank you!

A: Benedryl dosage

illlgalus,
I have a question and some suggestions.
Did you ask the clinic receptionist that you needed a dosage for a CAT? Why did they give you the dose for a dog?

Benadryl isn't usually prescribed for cats. The dosage for benadryl, as well as other antihistamines, has not been well established for cats. If your vet told you a specific dose to give, call the clinic back and ask to talk to THAT vet, get the RIGHT dosage, and be very careful to give an accurate dose at the right intervals and monitor your cat closely for adverse effects.

Even at low doses, benadryl can cause depression, hyperexcitability, vomiting, fever, muscle tremors, rapid or depressed heart rates, disorientation, and seizures in cats, depending on the cats age, general health, sensitivity to antihistamines and how effectively the cat metabolizes the drug.

In addition, it isn't a good idea to take the advice of a vet office receptionist without having them communicate directly with the vet. They don't generally have any training in the direct medical care of animals and may not be giving you accurate information.
You can insist on speaking directly to the vet--even if they have to call you back at the end of their workday.

Q: Benedryl dosage

Yes of course I asked for the cat dosage. That was why the whole thing was so stupid. And yes I asked to speak to my vet, the receptionist asked why and when I told her was when she told me the dosage. I also asked to double check that it is safe for a Diabetic cat (in years past my sister and I have both been told by different vets to give Benedryl to our cats, but this particular cat is Diabetic), so she checked with one of the other vets who said it is ok.
I can call back and ask to have my vet call me. I see the dosage posted on various boards but some say 1 mg and some say 1/2!
I certainly don't want to overdose him!!

I would always recommend to ask a vet, but since your vet has told you it's safe in the past and you're only looking for confirmation of what the receptionist told you, I'll give you my input. The safe dosage is no more than .5mg per pound for cats. Some people even err on the side of safety and give only .25mg per pound. It can be given every 12 hours. If he's 12 pounds or bigger, then giving him a 1/4 tablet of the standard Benadryl tablet will be okay (make sure there is no decongestant in it, only an antihistamine - diphenhydramine hydrochloride). If he's 10 lbs or under, you should use the liquid and use a syringe to give him .10ml (cc's), or slightly less according to his weight. That is assuming it is the standard strength - 50mg/ml.

Benadryl is best used for acute allergies (like to insect stings or vaccinations) and upper respiratory symptoms. If it's a chronic skin allergy you're treating, you should consult your vet about something longer lasting with fewer side effects, like cortisone.

A: Benedryl dosage

Sorry if I sounded condescending, I just couldn't imagine why they would suggest 1 mg per pound in a cat. It's a huge dose even for a dog! The normal dose for a human with minor allergies is only 50 mg, even for a 160 lb person. g

UTBRKK was right to suggest perhaps using a lower dose to start. Since your cat is diabetic, it would be wise to start with the 1/4 mg per lb or even less if possible.

If your cat doesn't like the liquid (lots of cats don't like human flavors and many liquid medications contain alcohol--unless you get the alcohol free children't type), or you can't find benadryl pills (they're usually in caplets or capsules these days) that you can divide accurately you can try a compounding pharmacy. Most compounding pharmacies can crush OTC medications and put them into a suspension or solution in almost any flavor (even perhaps tuna!!).
