To the Editor.—
The article by Kjeldgaard et al (218:882, 1971) on "Methadone-Induced Pulmonary Edema" was of interest in view of our recent experience with a similar patient. That morphine and heroin may cause an identical picture is, as the authors state, well documented, but it should also be noted that methadone has previously been reported to produce pulmonary edema.Gardner1 in reviewing the postmortem findings, laboratory analyses, and hospital records of 12 patients who died from methadone overdosage found that pulmonary edema was present in all cases. Methadone was the only agent identified in five cases, whereas the coincidental misuse of another drug occurred in the remaining seven patients.
