How do you convert millagrams to Mls? I have a 300mg/100ml malarial medicine I need to give to my 2 year old son. The directions call for 4mgs/kg on day one followed by 2mgs/kg for the following 4 days... only my dosing syringe is in mls and it's driving me crazy!

Why can't the pharmacutical companies think like normal people and put these instructions in one universal ml language:rolleyes:

My son weighs 11 kgs

Your pharmacist should be willing to calculate the correct dosage for you. The manufacturer can't know know the patients weight, so the dosage has to be determined by the physician and the pharmacist. As the doctor should know the patient's weight he/she should be indicating the needed amount of active ingredient on the prescription. The pharmacist should be labeling the container with the volume of solution that would administer that amount.

CALL THE PHARMACIST to have him/her verify our calculations!

Since most dosages would be measured by volume, the 300mg/100ml shows the amount of active ingredient in 100ml of the solution.

Let's divide both sides of that ratio by 300.

300mg/100ml:1mg/0.333ml, so you need 1/3 ml to administer a mg of the active ingredient.

11 times 1/3 would be 11/3 otherwise known as 3 2/3 or 3.666ml

Fortunately, this is a very EASY question for me as I do it on a daily basis.

Okay, so your son weighs 11 kg. Multiply that by the 4mg per kg per day. That gives you 44 mg a day right.

So, the doctor's order is for 44 mg per day. Now, what you have is 300mg/100ml. So what you do is divide 44 by 300 and you get 0.1467. Now, you multiply that by 100. That gives you 14.6667

You can't give 14.667 ml so you have to round it to 15ml per day. And on the following 4 days he only needs 7 ml per day

Now, the question I have is how often does the doctor want it given? Once? Twice? Three times a day?

If you can tell me how often, I can tell you EXACTLY how much to give each time.

This would be a totally inaccurate amount of medication given due to your child's weight. It would NOT be therapeutic and could lead to medication resistance.

I do these calculations on a daily basis, and have been tested extensively on medication administration.

The first few days your child should be given 15 ml. and the last few days your child should be given 7 ml. You just left out how often it should be given.
