Aerodigestive adverse effects during intravenous pentamidine infusion for Pneumocystis jirovecii pneumonia prophylaxis.

Aerodigestive adverse effects (AD-AE) during intravenous pentamidine (IV-P) infusion for Pneumocystis jiroveci pneumonia prophylaxis are uncommon in retrospective chart review studies. We conducted a survey in patients on IV-P, which included 31 specific questions. Twenty-five patients were included in the analysis; AD-AE were observed in 22 (88%) with recurrence of symptoms in 88% participants with subsequent infusions. Five leading symptoms were congestion (48%), lip tingling (32%), nausea (28%), tongue tingling (24%), vomiting, and throat swelling (17%); multiple symptoms were reported in 72% of the patients. In conclusion, AD-AE of IV-P infusion are common, self-limited, and tend to be recurrent.
