Central nervous system side effects may be either depressant or excitatory. Excitatory symptoms are sometimes ignored as possible side effects of morphine (the active ingredient contained in Roxanol-T) Severe adverse effects such as respiratory depression can be treated with the opioid antagonist naloxone.
Patients receiving continuous infusion of morphine sulfate via indwelling intrathecal catheter should be monitored for new neurologic signs or symptoms. Further assessment or intervention should be based on the clinical condition of the individual patient.
Myoclonic spasms may occur in patients receiving high dose morphine, particularly in the setting of renal dysfunction. Hyperalgesia has also been reported with high doses.
Nervous system side effects have been frequently reported and include drowsiness and sedation. Inflammatory masses including granulomas (some of which have resulted in serous neurologic impairment including paralysis) have been reported to occur in patients receiving continuous infusion of opioid analgesics including morphine sulfate via indwelling intrathecal catheter. Delirium, seizures, tremors, dizziness, muscle twitches, malaise, and confusion have also been reported.
Respiratory side effects including respiratory depression have been reported frequently. Bronchospasm has been reported in patients with underlying pulmonary disease.
Gastrointestinal side effects including nausea, vomiting, dyspepsia, constipation, dry mouth, increased gastroesophageal reflux, intestinal obstruction, and increased biliary pressure have been reported.
Morphine may cause constriction of the common bile duct and spasm of the sphincter of Oddi, thereby increasing intrabiliary pressure and worsening, rather than relieving, biliary colic.
In addition, morphine may cause intense but uncoordinated duodenal contraction and decreased gastric emptying.
Withdrawal symptoms have been reported to have included agitation, restlessness, anxiety, piloerection, insomnia, convulsions, tremor, abdominal cramps, blurred vision, vomiting, and sweating.
Other side effects include a withdrawal symptoms after either abrupt cessation or fast tapering of morphine.
Cardiovascular side effects including hypotension related to a transient decrease in systemic arterial resistance has been reported, particularly in the setting of myocardial infarction.
Psychiatric side effects have included fearfulness, agitation, thinking disturbances, paranoia, psychosis, hypervigilance, and hallucinations.
Genitourinary side effects including acute urinary retention have been reported.
The risk of acute urinary retention is very high when morphine is administered by epidural or intrathecal injection. Clinicians should be attentive to the increased risk of urosepsis in this setting, particularly if instrumentation of the urinary tract is necessary.
Hematologic side effects including immune thrombocytopenia has been rarely reported.
Endocrine side effects such as menstrual irregularities including amenorrhea have been reported. Reduced male potency and decreased libido in both men and women have also been reported.
Musculoskeletal side effects including opioid-induced involuntary muscle hyperactivity has been reported with chronic, high doses.
Dermatologic side effects including sweating, flushing, pruritus have been reported frequently. A case of acute generalized exanthematous pustulosis has also been reported.
Ocular side effects include keratoconjunctivitis and allergic conjunctivitis associated with lid urticaria. Visual disturbances and miosis have also been reported. A study has reported a temporary 26% decrease in pupil diameter following the administration of IV morphine (the active ingredient contained in Roxanol-T)
Hypersensitivity reactions including anaphylactoid reactions have been reported to occur very rarely.
Droperidol (2.5 mg intravenously) has been used successfully to reverse the pruritus associated with epidural morphine (the active ingredient contained in Roxanol-T) 2 or 4 mg dosages. A larger dose of droperidol (5 mg) unexplainably does not appear to reverse the pruritus.
General side effects including a sense of warmth has been frequently reported.
Hepatic side effects including increases in hepatic enzymes have been reported infrequently.
