What does dosage refer to?

• A. Amount and frequency of a medicinal drug that may be taken safely
• B. The route of administration
• C. The expiration date
• D. The brand name

Answer: (A)

Dosage is about how much medicine you take at one time and how often you take it. It’s the balance that makes a drug work safely and effectively: enough to treat the condition, but not so much that it causes harm. The label or your clinician’s instructions tell you the exact amount per dose and the interval between doses, and sometimes how long to continue. The way you take the medicine (pill, liquid, injection) can affect how it is absorbed, but the dosage itself refers to the amount and the frequency. Expiration date and brand name are separate details that don’t define how much or how often you should take the drug. For example, a instruction might say 500 mg every 12 hours for 7 days, illustrating both the amount and the timing needed for the treatment to work safely.
