⊘Indications and dosages
➣Pneumocystis jiroveci pneumonia
Adults and children ages 5 and older: 4 mg/kg I.V. or deep I.M. daily for 14 days
➣ To prevent P. jiroveci pneumonia in high-risk patients with human immunodeficiency virus
Adults: 300 mg by inhalation once q 4 weeks using Respigard II nebulizer
• Visceral leishmaniasis
• History of anaphylaxis from pentamidine or diamidine compounds (inhalation only)
(Note: No absolute contraindications exist for patients with P. jiroveci.)
Use cautiously in:
• anemia, blood dyscrasias, hepatic or renal disease, hypoglycemia, diabetes mellitus, ventricular tachycardia, hypocalcemia, hypertension, hypotension
• pregnant or breastfeeding patients
• children (safety and efficacy of inhalation solution not established).
• For I.V. infusion, dilute 300 mg-vial with sterile water for injection. Withdraw prescribed dosage, then dilute further in 50 to 250 ml of dextrose 5% in water; infuse over 60 to
• For I.M. use, dilute 300 mg-vial with 3 ml of sterile water for injection. Withdraw prescribed dosage; administer deep I.M. using Z-track method.
• Keep patient supine during I.M. or I.V. administration to minimize hypotension.
• For inhalation, dilute in 6 ml of sterile water and administer through nebulizer at a flow rate of 6 L/minute from 50-psi compressed air source. Don't mix inhalation solution with other drugs.

☞ Closely monitor blood pressure and blood glucose. Watch for arrhythmias and evidence of pulmonary infection, blood dyscrasias, and pancreatitis during and after I.M. or I.V. administration, until patient is stable. (Severe, life-threatening reactions may occur.)
• Assess I.V. site closely during and after I.V. administration. Know that sterile abscess, pain, or induration may occur at injection site.
• Evaluate neurologic status.
• Monitor CBC (including platelet count), calcium and potassium levels, and kidney and liver function tests.
• Explain purpose of therapy. Stress importance of completing entire course of treatment.
☞ Teach patient to recognize and immediately report serious cardiovascular and neurologic reactions, abdominal pain, and easy bruising or bleeding.
• Teach patient how to use aerosol.
• Tell patient to notify prescriber if infection worsens.
• Advise patient to minimize GI upset by eating small, frequent servings of food and drinking plenty of fluids.
• Caution patient to avoid driving and other hazardous activities until he knows how drug affects concentration and alertness.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the tests mentioned above.
