Methadone Powder

Life-Threatening Respiratory Depression
Respiratory depression, including fatal cases, have been reported during initiation and conversion of patients to methadone, and even when the drug has been used as recommended and not misused or abused (see WARNINGS). Proper dosing and titration are essential and Methadone Hydrochloride should only be prescribed by healthcare professionals who are knowledgeable in the use of methadone for detoxification and maintenance treatment of opioid addiction. Monitor for respiratory depression, especially during initiation of Methadone Hydrochloride or following a dose increase. The peak respiratory depressant effect of methadone occurs later, and persists longer than the peak pharmacologic effect, especially during the initial dosing period (see WARNINGS).
