What is an OPA?

0.55% Ortho-phthalaldehyde Ortho-phthalaldehyde 0.55% (OPA) was introduced to marked as Cidex OPA Solution in 1999. 

OPA is commonly used as a high-level disinfectant for medical instruments. Disinfection with OPA is indicated for semi-critical instruments that come into contact with mucous membranes or broken skin, such as specula, laryngeal mirrors, and internal ultrasound probes.

Why the EPA wants you to eliminate glutaraldehyde use:**

  • Glutaraldehyde is a potent occupational skin irritant.
  • Glutaraldehyde is a recognized cause of occupational asthma.
  • Patients, visitors and hospital employees may be needlessly exposed to glutaraldehyde vapors in patient rooms and clinic areas where open bins or poorly ventilated reprocessing units are in use.
  • Cost-competitive alternatives exist that meet infection control standards and reduce risks to patient, visitor and employee health.
  • Several regulatory organizations, including OSHA and NIOSH, are re-evaluating their exposure limits for glutaraldehyde.
