Tablet Dosage Calculation - Basic Mathematics
A few examples showing how to do tablet dosage calculation. Example #1: Say the dosage strength is 100 mg and there are 200 tablets in the bottle. If the doctor orders 300 mg, how many tablets will you give? 100 mg + 100 mg + 100 mg = 300 mg. As you can see, you need 3 tablets of 100 mg to reach the dosage of 300 mg ordered by the doctor.
