For how long must a purchaser/licensee maintain a transaction info file after the transaction date?

In South Dakota, a purchaser or licensee is required to maintain a transaction information file for a period of six years after the transaction date. This requirement is in place to ensure that accurate records are kept for regulatory purposes, which allows for accountability and traceability in the distribution and dispensing of pharmaceuticals. Keeping transaction records for six years strikes a balance between allowing sufficient time for any necessary audits or investigations while not requiring indefinite record retention. This timeframe is consistent with many state and federal regulations governing record-keeping in the pharmacy practice, ensuring compliance with legal and professional standards. The other options provide longer durations that exceed what is mandated, making them unsuitable choices.
