Final answer:
An override pull is necessary when a critical medication needs to be given to a patient urgently and cannot wait for pharmacy verification. This procedure is allowed within specified protocols to ensure patient safety while providing timely treatment.
Step-by-step explanation:
An override pull is sometimes necessary for administering medication that hasn't been verified by the pharmacy due to urgent patient needs. When a medication is critical for a patient's treatment and cannot wait for the usual verification process, healthcare providers may have to use an override pull to access the medication promptly. This procedure is typically governed by strict protocols to balance the need for rapid access to medications with the risk of bypassing standard safety checks.
Pharmacovigilance systems continue to monitor new drugs after they reach the market to ensure long-term safety and effectiveness in various patient subgroups. The Food and Drug Administration (FDA) regulates medicines to protect the public from unsafe drugs, requiring extensive testing before market approval. However, the need for swift treatment in certain clinical circumstances justifies the use of override pulls, despite the potential risk from less oversight.
