"All patients should be temperature-screened for fever upon arrival," Dr. King says. "Anyone with a fever, even low grade, should be required to reschedule." Any and all cancellation fees will be waived at this time per CDC guidelines for all practicing medical facilities , so if you feel at all nervous or symptomatic in any way leading up to your Botox appointment (or any other appointment, for that matter), you can cancel without penalty.
