What is the dosage per pound in a cat for penicillin G injectible Pen-Aqueous?

Answer 1

Aqueous solutions have different concentrations of active ingredient (ie: the antibiotic) vs. the suspension it is diluted in.

The diluted concentration is measured in IU per mL.

Some Penicillin G Procaine & Penicillin G Benzathine solutions have 150,000 IU of each, different brands have different concentrations per mL.

Therefore there is no one-size-fits-all answer to this question. If you had specified the IU/mL then someone could have answered.

IGNORE ANSWERS THAT GIVE A DOSAGE FOR THIS QUESTION!!!

Those people are answering blindly and you could overdose your pet!!

Answer 2

Liquid injectable penicillin can be bought without prescription at a feed or farm store. The dosage for cats is 1/2 ml (.5ml) per cat (you need not worry about per-pound.) Small syringes 1ml, 3ml are easiest to use, get 20 or 24 gauge needles to use on the cat, and if possible, one larger gauge needle (16-18) to withdraw the liquid from the bottle. You MUST keep it refrigerated, and be sure to shake the bottle before drawing - penicillin has a tendency to separate.

Draw a small amount into the syringe over the dosage you will be giving, allow the syringe to come to room/body temperature (just hold in your closed hand for a minute) and holding the syringe needle-up, tap on it a few times to remove air bubbles, and discard a small amount - back down to the 1/2ml dosage. (do NOT warm up whole bottle, just what you will be using. Again, penicillin MUST be kept refrigerated until used)

Restraining cat in towel as suggested below is a good tip. Subcutaneous administration is the safest, and releases the dose slower and more evenly into the cat's system. Raising the skin at the back of the neck and using for the injection site as described below is the perfect place.

One-time treatment will generally stop beginning infections from MINOR wounds, bites, etc. Once a day for at least 3 days is a better course.

PS Do not plan on keeping the remainder of the bottle, even in the refrigerator, more than about 2 weeks. ("until the next time I need it") Penicillin is a living culture, don't take the chance that later on, with the seal having been broken and time passed, that it appears fine but is actually powerless.

I bought a small bottle of penicillin G for cattle at a farm store. I am sure it was under $10.00. A 1 ml syringe works best for the dosing. I think the smallest the farm store had was 3 or 6 ml. I had a 1ml from when my oldest son had to give himself allergy shots. I was told to give 1/4ml to the younger cats and 1/2 to the adults. My friend that is a vet tech said if I gave them a little to much it wouldn't hurt but my farmer friend said if I gave to much they would loose some hair around the injection site. As for the needle I used a 20 gage. It was nice and short but a little to big I thought. The lower the number the bigger the needle. I was told I would have trouble drawing it out with a smaller one. I didn't have a problem so not sure about that. The directions on the bottle say you need to let the penicillin warm to room temp. I wrapped the cat in a towel and had my daughter hold them tight. I grabbed them by the scruff of their neck and gave the shot just under the skin at the base of my hold. Needle went in a little hard but only one cat gave a little growl.

Vets use a 20 gauge 1 inch long needle to draw up and inject because the powder particles in the suspension are too big for the smaller needles. If you don't use the larger diameter needles you will have only the suspension fluid in the needle to inject.

Also you must wait for it to come to room temperature for the powder to mix with the fluid properly.

Be certain to draw the plunger back a bit after inserting needle to make sure you are not in a vein. There should be no blood as you draw back(it should be clear.) Then inject slowly and steadily. Draw the needle out smoothly.

MINIMUM dosing for penicillin -g would be:

1-10 lbs would be 1/4 ml,

10-20 lbs would be 1/4 to 1/2 ml

20 - 50 lbs would be 1/2 to 1ml

Good luck!!!

I believe there is an error in the above dosing info. Per the website cited above, the weight amounts given are in kilograms, not pounds as shown above. To convert: kg x 2.2 = pounds.

Also, the website above states that the injections should be given intramuscularly (IM)ONLY, therefore subcutaneous (SQ) injection at the scruff of the neck is not the proper injection method/site. Choose a meaty muscle (hind leg), insert needle, aspirate (pull the plunger back and check for blood) to make sure you are not in a vein (as injecting penicillin directly into a vein can kill) and then shoot the drug. Takes a little more time, but holding the cat in the towel is the way to go. Do it right for safety and efficacy.

Answer 3

what is the dosage of penicillen in c c for dogs for pen-aqueous 300,000 units per ml

The bottle says 3000 units per body weight for farm animals. I am a pharmacy tech and for domestic cats and dogs I have figured it out this way from a friend who is a vet tech from the info she gave me.

How much would you give a 10 pound cat if the bottle says 3000 units per pound and it is 300,000 per unit. (this is the penicillin strength that I got from the farm supply store)

The cat is 10 lbs so he gets 30,000 units. (10 x 3,000)

The cat needs 30,000 units and we have 300,000 per ml.

So we need to figure how many less ml we need.

30,000 (what we have TIMES 1ML DIVIDED BY 300,000 (what we have) EQUALS 0.1ML

The cat needs 0.1ml = 30,000 units of penicillin G

This would go for a dog or cat I think. This in no way replace good vet care. PLEASE TAKE YOU PET TO THE VET WHEN THEY ARE IN NEED. I ONLY USE PENICLLIN WHEN I CAN'T GET TO THE VET OR ONLY IN EMERGENCIES.

Answer 4

This varies depending upon the formulation of the penicillin (injectable, topical, oral), the location and type of infection and the overall health status of the dog. If you believe your dog has a condition that needs to be treated with penicillin, you should take your dog to your veterinarian.

You should not try to treat your dog at home. This particular antibiotic might not be benefical for your dog's specific needs or needed. The only answer to correctly treating your dog is to take him or her to a Veterinarian.

Answer 5

For most purposes, the penicillin dosage for cats is 5 mg per pound every 8 hours. For instance, a 6 pound cat would need 30 mg 3 times a day.

Answer 6

The oral dosage of penicillin per pound for a dog should not be determined by any other instruction other then a vet due to health risk.

Answer 7

0.5ml for a 5 kg cat.
