Medically reviewed by Drugs.com. Last updated on Jul 27, 2019.

Pronunciation

(bel a DON a & OH pee um)

Index Terms

  • B&O
  • Opium and Belladonna

Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Suppository: Belladonna extract 16.2 mg and opium 30 mg; belladonna extract 16.2 mg and opium 60 mg

Pharmacologic Category

  • Analgesic Combination (Opioid)
  • Analgesic, Opioid
  • Antispasmodic Agent, Urinary

Pharmacology

The pharmacologically active agents present in the belladonna component are atropine and scopolamine. Atropine blocks the action of acetylcholine at parasympathetic sites in smooth muscle, secretory glands, and the CNS causing a relaxation of smooth muscle and drying of secretions. The principle agent in opium is morphine. Morphine binds to opiate receptors in the CNS, causing inhibition of ascending pain pathways, altering the perception of and response to pain.

Absorption

Rectal absorption is dependent upon body hydration, not temperature

Metabolism

Hepatic

Use: Labeled Indications

Pain associated with ureteral spasm: Management of ureteral spasm pain severe enough to require an opioid analgesic.

Limitations of use: Reserve belladonna and opium suppositories for use in patients for whom alternative treatment options (eg, nonopioid analgesics or opioid combination products) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.

Contraindications

Hypersensitivity to belladonna, opium or any component of the formulation; significant respiratory depression; acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment; use of MAO inhibitors (concurrent or within 14 days); GI obstruction (known or suspected), including paralytic ileus; glaucoma; severe renal or hepatic disease; opioid idiosyncrasies; convulsive disorders; acute alcoholism; delirium tremens; premature labor.

ALERT: U.S. Boxed Warning

Addiction, abuse, and misuse:

Belladonna and opium suppositories expose patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient’s risk prior to prescribing belladonna and opium suppositories, and monitor all patients regularly for the development of these behaviors and conditions.

Life-threatening respiratory depression:

Serious, life-threatening, or fatal respiratory depression may occur with use of belladonna and opium suppositories. Monitor for respiratory depression, especially during initiation of belladonna and opium suppositories or following a dose increase.

Accidental exposure:

Accidental exposure of even one dose of belladonna and opium suppositories, especially by children, can result in a fatal overdose of opium.

Neonatal opioid withdrawal syndrome:

Prolonged use of belladonna and opium suppositories during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.

Risks from concomitant use with benzodiazepines or other CNS depressants:

Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of belladonna and opium suppositories and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.

Warnings/Precautions

Concerns related to adverse effects:

• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).

• Hypotension: May cause severe hypotension (including orthostatic hypotension and syncope); use with caution in patients with hypovolemia, cardiovascular disease (including acute MI), circulatory shock, or drugs that may exaggerate hypotensive effects (including phenothiazines or general anesthetics). Monitor for symptoms of hypotension following initiation or dose titration. Avoid use in patients with circulatory shock.

• Phenanthrene hypersensitivity: Use with caution in patients with hypersensitivity reactions to other phenanthrene-derivative opioid agonists (codeine, hydrocodone, hydromorphone, levorphanol, oxycodone, oxymorphone).

• Respiratory depression: [US Boxed Warning]: Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely for respiratory depression, especially during initiation or dose escalation. Carbon dioxide retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids.

Disease-related concerns:

• Adrenal insufficiency: Use with caution in patients with adrenal insufficiency, including Addison disease. Long-term opioid (one month or greater) use may cause secondary hypogonadism, which may lead to sexual dysfunction, infertility, mood disorders, and osteoporosis (Brennan 2013).

• Biliary tract impairment: Use opium with caution in patients with biliary tract dysfunction, including acute pancreatitis; may cause constriction of sphincter of Oddi.

• Cardiovascular disease: Use with caution in patients with cardiovascular disease.

• Drug abuse: Use with caution in patients with a history of opioid drug abuse or acute alcoholism; potential for drug dependency exists. Tolerance, psychological and physical dependence may occur with prolonged use.

• Head trauma: Use with extreme caution in patients with head injury, intracranial lesions, or elevated intracranial pressure (ICP); exaggerated elevation of ICP may occur.

• Prostatic hyperplasia: Use with caution in patients with prostatic hyperplasia; may cause urinary retention.

• Psychosis: Use with caution in patients with toxic psychosis; may exacerbate condition.

• Respiratory disease: Use with caution and monitor for respiratory depression in patients with significant COPD or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or preexisting respiratory depression, particularly when initiating and titrating therapy; critical respiratory depression may occur, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.

• Seizure disorders: Use with caution in patients with seizure disorders; may cause or exacerbate preexisting seizures.

• Thyroid dysfunction: Use with caution in patients with myxedema; may exacerbate condition.

Concurrent drug therapy issues:

• Benzodiazepines or other CNS depressants: [US Boxed Warning]: Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of morphine and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosage and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation. Use is contraindicated in patients with acute alcoholism.

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Cachectic or debilitated patients: Use with caution in cachectic or debilitated patients; there is a greater potential for critical respiratory depression, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.

• Elderly: Use with caution in elderly patients; may be more sensitive to anticholinergic and opioid-induced adverse effects. Use opioids for chronic pain with caution in this age group; monitor closely due to an increased potential for risks, including certain risks such as falls/fracture, cognitive impairment, and constipation. Clearance may also be reduced in older adults (with or without renal impairment) resulting in a narrow therapeutic window and increasing the risk for respiratory depression or overdose (Dowell [CDC 2016]). Consider the use of alternative nonopioid analgesics in these patients.

• Neonates: Neonatal withdrawal syndrome: [US Boxed Warning]: Prolonged maternal use of opioids during pregnancy can cause neonatal withdrawal syndrome in the newborn, which may be life-threatening if not recognized and treated according to protocols developed by neonatology experts. If prolonged opioid therapy is required in a pregnant woman, ensure treatment is available and warn patient of risk to the neonate. Signs and symptoms include irritability, hyperactivity, abnormal sleep pattern, high-pitched cry, tremor, vomiting, diarrhea, and failure to gain weight. Onset, duration, and severity depend on the drug used, duration of use, maternal dose, and rate of drug elimination by the newborn.

Other warnings/precautions:

• Abuse/misuse/diversion: [US Boxed Warning]: Belladonna and opium exposes patients and other users to the risks of addiction, abuse, and misuse, potentially leading to overdose and death. Assess each patient’s risk prior to prescribing; monitor all patients regularly for development of these behaviors or conditions. Use with caution in patients with a history of drug abuse or acute alcoholism; potential for drug dependency exists. Other factors associated with increased risk include younger age, concomitant depression (major), and psychotropic medication use. Consider offering naloxone prescriptions in patients with factors associated with an increased risk for overdose, such as history of overdose or substance use disorder, higher opioid dosages (≥50 morphine milligram equivalents/day orally), and concomitant benzodiazepine use (Dowell [CDC 2016]).

• Accidental exposure: [US Boxed Warning]: Accidental exposure of even one dose of belladonna and opium suppositories, especially by children, can result in a fatal overdose of opium.

• Appropriate use: Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals.

• Withdrawal: Concurrent use of mixed agonist/antagonist analgesics (eg, pentazocine, nalbuphine, butorphanol) or partial agonist (eg, buprenorphine) analgesics may precipitate withdrawal symptoms and/or reduced analgesic efficacy in patients following prolonged therapy with mu opioid agonists. Do not abruptly discontinue; taper dose gradually when discontinuing.

Monitoring Parameters

Pain relief, respiratory and mental status, blood pressure; bowel motility; signs of misuse, abuse, and addiction; signs or symptoms of hypogonadism or hypoadrenalism (Brennan 2013). Anticholinergic effects (eg, dry mouth, blurry vision, urinary retention).

Pregnancy Considerations

[US Boxed Warning]: Prolonged use of opioids during pregnancy can cause neonatal withdrawal syndrome, which may be life-threatening if not recognized and treated according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available. Use is not recommended prior to or during labor and delivery.

The pharmacologically active components of belladonna are atropine and scopolamine, and the principle agent in opium is morphine. See individual agents.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience dry mouth, loss of strength and energy, vomiting, or nausea. Have patient report immediately to prescriber difficulty breathing, slow breathing, shallow breathing, severe fatigue, severe dizziness, passing out, severe abdominal pain, severe constipation, seizures, chest pain, confusion, tachycardia, blurred vision, urinary retention, sensitivity to light, signs of serotonin syndrome (dizziness, severe headache, agitation, hallucinations, tachycardia, abnormal heartbeat, flushing, tremors, sweating a lot, change in balance, severe nausea, or severe diarrhea), signs of adrenal gland problems (severe nausea, vomiting, severe dizziness, passing out, muscle weakness, severe fatigue, mood changes, lack of appetite, or weight loss), sexual dysfunction (males), amenorrhea, decreased libido, or infertility (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
