Final answer:
Prescription must include a drug regimen, detailing the dosage, frequency, and duration of medication use, to ensure patient safety and drug effectiveness is true.
Step-by-step explanation:
True, a prescription must specify a drug regimen. A drug regimen outlines the specific way a medication is to be taken, including the dosage, the frequency, and the duration of treatment. This is critical for ensuring that the drug is used safely and effectively.
When healthcare providers prescribe medication, especially for new drugs that must go through extensive scrutiny like New Drug Applications (NDAs), they often stipulate a regimen that patients are expected to adhere to. The regimen ensures the drug's efficacy and minimizes potential risks and side effects when used as directed.
