Combining Hydromorphone Hydrochloride and Metaxalone is a major interaction and should generally be avoided without close medical supervision.
Patients may experience profound sedation, increased risk of respiratory depression, hypotension, and psychomotor impairment. This can lead to decreased level of consciousness, dizziness, confusion, and impaired coordination, significantly increasing the risk of falls and accidental injury.
Mechanism: Hydromorphone, an opioid analgesic, primarily acts on mu-opioid receptors in the central nervous system (CNS) to produce analgesia, sedation, and respiratory depression. Metaxalone, a centrally acting skeletal muscle relaxant, also exerts its effects through general CNS depression. The concurrent administration of these two agents results in an additive depressant effect on the CNS.
