Calculating dosage in tabs, caps, ml This tutorial demonstrates calculating the number of tablets, capsules, or milliliters to prepare. Our first example: 35mg of Sinequan(Doxepin) has been prescribed po. How many ml should you administer if the Sinequan is available in a strength labeled 10 mg in 1 ml?

4
Calculating dosage in tabs, caps, ml Step One – Write down the dosage you want to administer. Step Two – Write down the known strength. Step Three – Reduce the units. Step Four – Perform the math.

Calculating dosage in tabs, caps, ml Our first example: 35mg of Sinequan(Doxepin) has been prescribed po. How many ml should you administer if the Sinequan is available in a strength labeled 10 mg in 1 ml? Step One – Write down the dosage you want to administer. In our example, we want to administer 35 mg. 35 mg 1 We’ll write this as a fraction with a denominator of 1.

Calculating dosage in tabs, caps, ml Our first example: 35mg of Sinequan(Doxepin) has been prescribed po. How many ml should you administer if the Sinequan is available in a strength labeled 10 mg in 1 ml? In our example, the strength is 10mg in 1 ml. (Step One) 35 mg 1 We can write this strength two ways. Step Two – Write down the known strength. 1 ml 10 mg 1 ml or Since the fraction we wrote in step one has mg on the top, our next fraction needs to have mg on the bottom. (Step Two) 1 ml 10 mg

7
Calculating dosage in tabs, caps, ml Cross off any matching pairs of unit labels. The label left should be what you want to find. (Step One) 35 mg 1 Step Three – Reduce the units. (Step Two) 1 ml 10 mg In this example the only unit left is ml which is what we want to find.

8
Calculating dosage in tabs, caps, ml (Step One) 35 mg 1 Step Four – Perform the math. (Step Two) 1 ml 10 mg We have found that we to need administer 3.5 ml of Sinequan. 35 x 1 1 x = 3.5 ml Reduce any fractions and remember the units label. Our first example: 35mg of Sinequan(Doxepin) has been prescribed po. How many ml should you administer if the Sinequan is available in a strength labeled 10 mg in 1 ml? =

9
Calculating dosage in tabs, caps, ml Our second example: 500 mg of Keflex (Cephalexin) has been prescribed. 250 mg of Keflex is available in capsules. How many capsules should be administered? Step One – Write down the dosage you want to administer. In our example, we want to administer 500 mg. 500 mg 1 We’ll write this as a fraction with a denominator of 1.

(Step One) 500 mg 1 Step Two – Write down the known strength. In our example, the strength is 250 mg in 1 capsule. We can write this strength two ways. 1 capsule 250 mg 1 capsule or Since the fraction we wrote in step one has mg on the top, our next fraction needs to have mg on the bottom. (Step Two) 1 capsule 250 mg

12
Calculating dosage in tabs, caps, ml Step Four – Perform the math. We have found that we need to administer 2 capsules of Keflex. 500 x 1 1 x capsules 250 = 2 capsules Reduce any fractions and remember the units label. (Step One) 500 mg 1 (Step Two) 1 capsule 250 mg Our second example: 500 mg of Keflex (Cephalexin) has been prescribed. 250 mg of Keflex is available in capsules. How many capsules should be administered? X =
