Breakpoints

Drs. Ted Morton and Christine Lockowitz join Dr. Ryan Moenster to discuss all things amoxicillin, particularly in our pediatric patients. Our guests answer common questions, such as, what formulations should be used for certain infectious conditions and/or organisms and how to dose amoxicillin to maximize PK/PD optimization without inducing potential adverse events. It is a must-listen for all!

We’re starting 2026 off with a BLAST as Dr. Gregory Eschenauer and Dr. George R Thompson make their Breakpoints debut to discuss Blastomyces, Histoplasma, Coccidioides, and Cryptococcus. They join host Erin McCreary in reviewing epidemiology, diagnostics, clinical presentation, and treatment of these fungal infections. You won’t want to miss this episode!

Ring in the end of the year with our Breakpoints hosts and a review of all things IDWeek 2025! Join Drs. Erin McCreary, Julie Ann Justo, Whitney Buckel, and Ryan Moenster as they cover top late breaking abstracts, new stewardship data, practice-changing clinical trials, and much more.
