How long must a manufacturer keep written requests for prescription drug samples?

The correct duration for which a manufacturer must keep written requests for prescription drug samples is three years. This requirement aligns with federal regulations that mandate manufacturers to maintain records of requests for samples to ensure accountability and oversight regarding the distribution of prescription medications. By keeping these records for a minimum of three years, manufacturers can provide proof of compliance with regulations and help prevent misuse or abuse of samples, which is essential for maintaining proper prescribing practices and safeguarding public health.

In essence, retaining these records helps create a transparent process, which can be crucial in audits or investigations pertaining to drug samples. This three-year retention period allows for adequate time to verify that the distribution of samples aligns with regulatory requirements.
