**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?

**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.

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. We’ll write this as a fraction with a denominator of 1. 35 mg 1

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 Two – Write down the known strength. In our example, the strength is 10mg in 1 ml. We can write this strength two ways. 1 ml 10 mg 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 One) 35 mg 1 (Step Two) 1 ml 10 mg

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

**Calculating dosage in tabs, caps, ml**

(Step One) 35 mg 1 (Step Two) 1 ml 10 mg Step Four – Perform the math. 35 x 1 35 = Reduce any fractions and remember the units label. 1 x 10 10 = 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? We have found that we to need administer 3.5 ml of Sinequan.

**Calculating dosage in tabs, caps, ml**

Our second example: mg of Keflex (Cephalexin) has been prescribed 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. We’ll write this as a fraction with a denominator of 1. 500 mg 1

Our second example: mg of Keflex (Cephalexin) has been prescribed mg of Keflex is available in capsules. How many capsules should be administered? 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. 250 mg 1 capsule or 1 capsule 250 mg (Step One) 500 mg 1 (Step Two) 1 capsule 250 mg Since the fraction we wrote in step one has mg on the top, our next fraction needs to have mg on the bottom.

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