What are filter needles designed for in a pharmacy setting?

Filter needles are specifically designed to remove particulates from solutions, which is crucial in pharmacy settings where the integrity and safety of injectable medications must be ensured. These needles contain a small filter that traps particles, such as glass shards or rubber from vial stoppers, thereby preventing them from being injected into a patient. This function is particularly important when working with solutions that come from multi-dose vials or when reconstituting medications.

The use of filter needles helps to reduce the risk of contamination and maintains the sterility of the medication being administered. By filtering out particulates, these needles enhance patient safety and ensure that the injectable medication is suitable for use. The design and purpose of filter needles make them a vital tool in both hospital and retail pharmacy settings when preparing injectable therapies.
