Benedryl Conversion Help?

An injection of Diphenhydramine was given of 50mg/ml (.12ml 1M). How many mg would that be. The Benedryl pills are 25 mg each and I'm trying to see how many pills are equivalent to the injection. Also, what does the .12ml 1M mean? Thanks.

Update:

Chad, you're brilliant. That's it. There is also IV on the chart - intravenously. Now I understand better and I think I found my answer. I think it translates to 6.25 mg in pill form. That's what I needed. Thanks!!

Update 2:

Here's the full story. My cat had a swollen paw which required treatment from a vet. She received a benadryl injection and a steroid injection. I'm 99% sure the dose was .12 ml. With normal allergy problems, the cat would be given half of the smallest children's dose, which would be 6.25mg. The cat received an injection of 50mg/ml (.12 ml IM). If the same thing happens in the future, I want to be able to give my cat a pill rather than the liquid since the liquid makes them foam at the mouth and is not at all pleasant. So I'm trying to figure out how many grams of benadryl in pill form would be equal to the injection she received.

Update 3:

I remember it being written as .12 ml without the leading zero. I agree it should always be there but like you said, some doctors have notoriously bad handwriting.

    the 1m could actually be IM or intramuscular

    Doctors' handwriting is notoriously difficult to read. If the dose was .12, it SHOULD have been written 0.12 - there should always be a leading zero.

    Are you sure it's not 1/2 ml? That would be 25 mg, which is a normal adult dose., which is why the pills come that way.

    You'd need to know how many ml were injected to determine the amount of mg. Know also that something injected straight into your system is going to effect you differently than something taken by mouth, through the stomach, digested and then accepted into your system. So you can't compare these two directly. talk to a pharmacist or the medical professional who administered the injection.
