Treatment for Legionella pneumophila
IV therapy (erythromycin gluceptate, 0.5–1.0 g diluted in 125–250 mL of compatible solution per infusate, infused over 60–90 minutes every 6 hours [total daily dosage, 2–4 g]) should be continued until the patient can tolerate oral therapy
Note: Patients who are critically ill or those who have pneumonia may need up to 4 g/day of the IV preparation; once improvement occurs, the dosage of IV erythromycin should be reduced to 1 g orally 4 times a day
Diplococcus (Streptococcus) pneumoniae Infections
Erythromycin base, stearate, or estolate, 500 mg orally 4 times a day for 10 days is considered adequate for most strains
