What is one method by which samples can be provided to patients?

Providing samples to patients is predicated on ensuring they receive the medication safely and effectively. One method for distributing samples is through the hands of an adult caregiver or via mail. This approach allows for the necessary oversight and guidance that might be required when a patient receives a new therapy. If the sample is delivered in person, it not only facilitates direct interaction between the healthcare professional and the patient for education on how to use the medication properly but also allows the professional to verify the patient's understanding and answer any questions.

The option mentioning pharmacy distribution focuses more narrowly on traditional methods used within pharmacies, excluding flexibility in direct patient care settings. The stipulation of only distributing samples through healthcare professionals may limit accessibility, as not all patients may receive or have access to professional visits to collect samples. The option suggesting that samples should be provided only in emergency situations does not reflect the broader regulatory framework, which allows for the distribution of samples under appropriate conditions during regular pharmaceutical practice. Thus, providing samples via an adult or through mail aligns with regulations that prioritize patient safety and accessibility.
