MEDICATIONS MEASURED IN UNITS
Medications such as insulin, heparin, some antibiotics, hormones, vitamins, and vaccines are measured in units.
These medications are standardized in units based on their strengths. The strength varies from one medicine to
another, depending upon their sources, their conditions, and the methods by which they are obtained.
