For Healthcare Professionals

Applies to morphine: compounding powder, injectable solution, injectable tablet soluble, intravenous solution, oral capsule, oral capsule extended release, oral concentrate, oral solution, oral tablet, oral tablet extended release, rectal suppository, spinal solution

Nervous system

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 Statex) 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.[Ref]

Very common (10% or more): Drowsiness (28%)
Common (1% to 10%): Dizziness, sedation, fever, anxiety, confusion, tremor, diaphoresis, lethargy, feeling of warmth
Uncommon (0.1% to 1%): Withdrawal symptoms after either abrupt cessation or fast tapering of the drug, headache, chills, flu syndrome, malaise, withdrawal syndrome, pallor, facial flushing, syncope, loss of concentration, insomnia, amnesia, paresthesia, agitation, vertigo, foot drop, ataxia, hypesthesia, slurred speech, hallucinations, euphoria, apathy, seizures, myoclonus
Frequency not reported: Inflammatory masses including granulomas (some of which have resulted in serous neurologic impairment including paralysis) in patients receiving continuous infusion of opioids via indwelling intrathecal catheter[Ref]

Respiratory

Common (1% to 10%): Respiratory depression
Uncommon (0.1% to 1%): Hiccup, rhinitis, atelectasis, asthma, hypoxia, voice alteration, depressed cough reflex, noncardiogenic pulmonary edema, bronchospasm[Ref]

Gastrointestinal

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 (the active ingredient contained in Statex) may cause intense but uncoordinated duodenal contraction and decreased gastric emptying.[Ref]

Common (1% to 10%): Dry mouth, constipation, nausea, diarrhea, anorexia, abdominal pain, vomiting
Uncommon (0.1% to 1%): Dysphagia, dyspepsia, stomach atony disorder, gastroesophageal reflux, delayed gastric emptying, biliary colic, increased gastroesophageal reflux, intestinal obstruction[Ref]

Cardiovascular

Common (1% to 10%): Chest pain
Uncommon (0.1% to 1%): Tachycardia, atrial fibrillation, hypertension, hypotension, palpitations, bradycardia, vasodilation[Ref]

Psychiatric

Uncommon (0.1% to 1%): Abnormal thinking, abnormal dreams, depression, fearfulness, agitation, paranoia, psychosis, hypervigilance, hallucinations, delirium
Frequency not reported: Withdrawal symptoms after abrupt cessation of therapy[Ref]

Genitourinary

Uncommon (0.1% to 1%): Urinary abnormality, urinary retention, urinary hesitancy[Ref]

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.[Ref]

Hematologic

Common (1% to 10%): Anemia, leukopenia
Uncommon (0.1% to 1%): Thrombocytopenia[Ref]

Endocrine

Uncommon (0.1% to 1%): Hyponatremia due to inappropriate ADH secretion, gynecomastia, amenorrhea, reduced libido, reduced potency, prolonged labor[Ref]

Musculoskeletal

Common (1% to 10%): Asthenia, accidental injury
Uncommon (0.1% to 1%): Back pain, bone pain, arthralgia
Frequency not reported: Opioid-induced involuntary muscle hyperactivity with chronic high doses[Ref]

Dermatologic

Common (1% to 10%): Rash
Uncommon (0.1% to 1%): Decubitus ulcer, pruritus, skin flush[Ref]

Ocular

Uncommon (0.1% to 1%): Amblyopia, conjunctivitis, miosis, blurred vision, nystagmus, diplopia[Ref]

Hypersensitivity

Very rare (less than 0.01%): Hypersensitivity reactions, anaphylaxis[Ref]

Hepatic

Uncommon (0.1% to 1%): Increases in hepatic enzymes[Ref]

Metabolic

Common (1% to 10%): Peripheral edema
Uncommon (0.1% to 1%): Hyponatremia
