For aerosolized pentamidine, the normal dosage is 300 mg in 6 mL sterile water via Respirgard nebulizer every 4 weeks. This agent is better tolerated than dapsone or TMP-SMX. However, it is much more expensive and less effective than other prophylactic agents. Side effects include cough and bronchospasm. The potential for extrapulmonary Pneumocystis manifestations and apical lung disease exists. In addition, aerosolized pentamidine may diminish the diagnostic sensitivity of sputum induction and bronchoalveolar lavage.
