Combining Baclofen and Codeine Sulfate is a major interaction and should generally be avoided without close medical supervision.
Patients may experience severe CNS depression, including profound sedation, somnolence, and confusion. There is an increased risk of life-threatening respiratory depression, characterized by decreased respiratory rate and depth, potentially leading to hypoxia and hypercapnia. Additionally, impaired psychomotor function, dizziness, and ataxia are common, increasing the risk of falls and accidents.
Mechanism: Codeine sulfate, an opioid analgesic, and baclofen, a central nervous system (CNS) depressant and muscle relaxant, both act on the CNS to produce sedative effects. Their co-administration results in an additive depressant effect on the CNS, leading to enhanced inhibition of neuronal activity. This synergistic action can significantly impair respiratory drive and neurological function.

Codeine Sulfate
Codeine sulfate is an opioid agonist relatively selective for the mu-opioid receptor, but with a much weaker affinity than morphine. The analgesic properties of codeine have been speculated to come from its conversion to morphine, although the exact mechanism of analgesic action remains unknown.
Approved Uses (Indications)
Baclofen
INDICATIONS AND USAGE Baclofen injection (intrathecal) is indicated for use in the management of severe spasticity. Patients should first respond to a screening dose of intrathecal baclofen prior to consideration for long term infusion via an implantable pump. For spasticity of spinal cord origin, chronic infusion of baclofen injection (intrathecal) via an implantable pump should be reserved for patients unresponsive to oral baclofen therapy, or those who experience intolerable CNS side effects at effective doses. Patients with spasticity due to traumatic brain injury should wait at least one …
