Identify the source
An official product label, a registered clinical study, an animal experiment, and an online anecdote are different sources. Establish which one is being quoted before interpreting a dose. Identify the formulation, population, route, schedule, and purpose of the measurement.
Do not convert across contexts
An animal-study amount cannot be transferred directly to a person. Different molecules cannot be ranked by comparing milligram numbers. Even products containing the same active ingredient may have different presentations, indications, instructions, or pharmacokinetic characteristics.
Keep arithmetic separate from clinical decisions
Concentration arithmetic describes how much material is present in a volume. It cannot establish a safe dose, sterile preparation, compatible solvent, or appropriate route. This library’s laboratory calculator is limited to nonclinical arithmetic.
For prescribed medicines
Follow the current instructions for the exact prescribed product. A clinician determines whether treatment is appropriate and monitors response and adverse effects. A pharmacist can clarify the prescribed device. Research vials are not authenticated by a calculator or a dosing chart.
