I'm mathmatically challenged and can't find the conversions for things! Some of the articles posted here talk about mg of medication per lb of horse, but my syringes are in cc. Others list grams or ml. Is there a conversion or are they the same thing? Specifically I wanted to know how much Dexamethazone on ADT was suitable for a 1250 lb heavey horse. I was put on 5cc for 5 days, 5cc EOD for 5 days, then 3cc EOD for maintenance. When I looked up the article to see if this matched your recommended dosages I didn't know how to compare.

Here, to help you, is the best online conversion site I've found (it will convert anything to anything!): https://www.onlineconversion.com/

And, as a bonus, if you travel overseas, the best FX site I've used is www.oanda.com.

Mililiters (mls) and miligrams (mg) are NOT the same thing when talking about liquid medications. Heather you need to become aware that liquid medications usually have the active medicine dissolved into the liquid. The amount dissolved is called the concentration and usually expressed as mg / ml. That means the amount of the drug that is in each ml of liquid.

Different brands can have different amounts of medicine dissolved in the same amount of liquid, so they have different concentrations. Giving the same number of mls of these different drugs result in different dosages. Take the conentration (mg/ml) and multiply by the amount given in mls and you end up with the amount given.

So to answer your question above we need to know the concentration of the dexamethasone you were giving. There are 3 common ones available: 2 mg/ml, 3 mg/ml, and 4 mg/ml.
