Rat Care Corner / Re: Metacam Doses?
« Last post by Michael C on March 03, 2019, 01:16:39 PM »
I'm not a vet and dosing is complicated and there's some important terminology involved. I'm gonna over-explain for clarity.

MG: This is a unit of measurement for mass. It refers to how how much of the drug is in your medicine.

ML: This is a volume measurement for an amount of liquid.

KG: This is the unit of measurement for your rat's weight. There are 1000 grams (g) in a kilogram (kg) so the conversion is really easy. 600 g = .600 kg.

MG/ML: This is the concentration of medicine within a liquid. It refers to how many milligrams (mg) of medicine are in each milliliter (ml) of liquid. I believe the metacam you're using is 1.5 mg/ml, meaning there are 1.5 milligrams (mass) of medicine in each milliliter (volume) of liquid. Mass is the amount of matter an object contains, while volume is how much space it takes up.

MG/KG: This is the dose. It refers to how much medicine to give your rat based on their weight. The dose refers to how many milligrams of medicine to give your rat per each kilogram of their weight. Being that rats weigh less than a kilogram, it requires some math (or a dosing calculator) to help figure out the fraction. The RatGuide recommends somewhere in the range of .5 to 2 mg/kg for metacam. This means your rat will get .5 to 2 milligrams of the drug for each kilogram of their weight. Sometimes the recommendation is in lbs. instead of kg but you can google a mg/lb to mg/kg calculator to convert the numbers. 

Now we have to use all of these numbers to figure out how much liquid medicine to give. I think of it like sugar in a glass of water. If I mix 1 teaspoon of sugar into a glass of water and I want to consume a total of 1/2 teaspoon of sugar, I'll drink half the glass. If there's only 1/4 teaspoon of sugar in a glass, I'll need to drink two full glasses to get the 1/2 teaspoon of sugar.

Here comes the math part. The calculator linked above will help a lot. To use as an example, let's go with a dose that's exactly in the middle of the RatGuide's recommendations and say 1.25 mg/kg of metacam. We know your rat is about 600 grams or .6 kilograms so for a dose of 1.25 mg/kg, we'd want to give him .75 mg of medicine (1.25 mg/kg x .6 kg = .75 mg) -note; this number is amount of medicine we want to give but the amount of liquid you'll give will be dependent on the concentration of the suspension- If we want to give the rat .75 mg and there are 1.5 mg in each ml of the suspension, we'll give him .5 ml of liquid (.75 mg / 1.5 mg/ml = .5 ml). This is pretty close to what your vet recommended. Doing the math backwards, it looks like your vet is dosing him at 1 mg/kg, which is basically in the middle of what's recommended.

Using the dosing calculator for a 600 gram rat and 1.5 mg/ml metacam, below is a range of doses from weaker to stronger based on RatGuide's recommendations;

.5 mg/kg    = .20 ml (weakest)
.8 mg/kg    = .32 ml
1 mg/kg     = .40 ml
1.3 mg/kg  = .52 ml
1.5 mg/kg  = .60 ml
1.8 mg/kg  = .72 ml
2 mg/kg     = .80 ml (strongest)

tl;dr: Refer to Ratguide and use a dosing calculator.

Because we couldnít leave our stitches alone, we got a cone of shame added yesterday. Here we are sitting in the corner of the cage, moping and contemplating how horrible life is and hoping to guilt mom into taking the terrible contraption off.

Rat Care Corner / Metacam Doses?
« Last post by MaatAset on March 03, 2019, 10:15:21 AM »
My boy rat went through hernia surgery on Wed and started removing stitches. Though he didnít exhibit usual signs of pain, I was told to give him the pain meds I had from a previous surgery (from a previous vet) to help reduce inflammation and irritation so it may not bother him as much. I donít recall ever giving my rats more than like .2 of this stuff before and she wants me to give him .4 of the 1.5mL suspension (Iím breaking it in half, twice a day). He makes weird little noises after I give it to him though and it kind of weirds me out. I donít want to be giving him too much. He is a big boy at about 610kg. I need to weigh him to get his exact weight post surgery, but he is about 600kg.

Mostly, I want to know how do I calculate his dosage myself (like seriously dumb it down). And does this dose seem too high for about a 600kg rat?

Hello, and welcome!

I've had several of my girls with mammary tumors. Some I decided to have removed, but others weren't, because of the girls age. A tumor is a fairly easy surgery, but there are risks involved, just like with any surgery. You'll need to be sure your vet treats exotics, and is knowledgeable in tumor removal. It may also be a good idea to get your girl spayed as that will reduce the likelihood of more tumors developing. It can be a bit pricey for the surgery, but if you can't afford it out-of-pocket, ask your vet if they offer Care Credit. It is a credit card that can only be used for medical issues, like vet visits (some dentists, pharmacies, doctors, and a few other places also accept Care Credit for the humans!). Tumors can get quite large, and will make walking difficult for your ratty, and if left untreated (removed) may get large enough to be painful, and the skin covering the tumor may split open.

Ok, I've given you about all I can think of regarding tumors. There may be others along who know more. Good luck with her! And if you have pictures of her, we would LOVE to see her! What is her name? These forums seem to be quiet lately, not many of us come around here much these days, but we're always looking for more pet lovers who love their fur-babies!

EDIT: Haha! And NOW I look at your profile and see you joined in 2012!!

Iíve noticed recently my girl Luca has 2-3 mamorry tumors under her armpit. I would appreciate any and all information I can get applying to this topic. Iím willing to do whatever I can to give her the happiest life possible but could use your help and guiding hand in doing so. Iíve had 5 rats over the years and somehow this is my first to deal with this sort of situation. Any info helps!

Thx!

So sorry. My eighteen year old gets nose bleeds, too. And chokes on the postnasal.

With a newborn kitten years ago who had been in the birth canal too long, I super-gently put my mouth over nose and mouth and oh so carefully sucked a little salty liquid out. Then with massage the baby was back. Greatest squeak I ever heard! Adult rats can usually clear choking on their own. You could try helping by mouth or baby bulb but that would probably cause more panic.

Just asking--why meds in the sink instead of cage? We're down to three and they all get a baby jar lid with a bit of baby food meat served to each in the cage and the sick one has meds in hers. Nobody's the wiser.

Even with central heat set to 76 and plastic on windows sometimes it is only 60 in here! They have lots of crinkles to block the igloo door, a couple of hammocks big enough for all of them, a large heating pad on the top (logistically it can't go under), and they are right next to me, my electric blanket and my lamp. They also have a humidifier and an air cleaner and we clean cage more than weekly. When it is colder they hang together in the hammock under the heating pad. When warmer I find them various places.

One possibility (gulp) is a tumor in a sinus. Also, I had a Zymbal's Gland tumor start this way. Hope it's neither. Best wishes!
