Compounded Products Containing Triamcinolone-Moxifloxacin by Guardian Pharmacy Services (Dallas, Texas): Alert to Health Professionals – Adverse Events After Receiving Eye Injections

At least 43 patient reported adverse event after receiving eye injections of Guardian’s Pharmacy Services compounded triamcinolone-moxifloxacin product during cataract surgery. The patients reportedly experienced various symptoms, including vision impairment, poor night vision, loss of color perception, and significant reductions in best-corrected visual acuity and visual fields.
FDA identified multiple substances in Guardian’s product, including poloxamer 407 and poloxamer 407 degradants. FDA prepared in-house samples of Guardian’s product and found that autoclaving and sonication caused the poloxamer 407 to degrade. The amount of poloxamer 407 in Guardian’s product (12%, g/100 mL) is much greater than the maximum amount of poloxamers in FDA-approved ophthalmic products for topical administration (0.1-0.2%, g/100 mL), and the safety profile of drug products intended for intravitreal injection containing poloxamer 407 is unknown.
