Belladonna and Opium

5 WARNINGS AND PRECAUTIONS These preparations are not recommended for use in children. • Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients: Monitor closely, particularly during initiation and titration. (5.5) • Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. (5.6) • Severe Hypotension: Monitor during dosage initiation and titration. Avoid use of Morphine Sulfate Oral Solution in patients with circulatory shock. (5.7) • Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness: Monitor for sedation and respiratory depression. Avoid use of belladonna and opium suppositories in patients with impaired consciousness or coma. (5.8) 5.1 Addiction, Abuse, and Misuse Belladonna and opium suppositories contains opium, a Schedule II controlled substance. As an opioid, belladonna and opium suppositories exposes users to the risks of addiction, abuse, and misuse [ see Drug Abuse and Dependence (9) ]. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed belladonna and opium suppositories. Addiction can occur at recommended dosages and if the drug is misused or abused. Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing belladonna and opium suppositories, and monitor all patients receiving belladonna and opium suppositories for the development of these behaviors or conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as belladonna and opium suppositories, but use in such patients necessitates intensive counseling about the risks and proper use of belladonna and opium suppositories along with intensive monitoring for signs of addiction, abuse, and misuse. Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal diversion. Consider these risks when prescribing or dispensing belladonna and opium suppositories. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on the proper disposal of unused drug [ see Patient Counseling Information (17) ]. Contact local state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product. 5.2 Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical status [ see Overdosage (10) ]. Carbon dioxide (CO 2 ) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of belladonna and opium suppositories, the risk is greatest during the initiation of therapy or following a dosage increase. Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy with and following dosage increases of belladonna and opium suppositories. To reduce the risk of respiratory depression, proper dosing of belladonna and opium suppositories is essential [ see Dosage and Administration (2.2) ]. Overestimating the belladonna and opium suppositories dosage when converting patients from another opioid product can result in a fatal overdose with the first dose. Accidental exposure of even one dose of belladonna and opium suppositories, especially by children, can result in respiratory depression and death due to an overdose of opium. 5.3 Neonatal Opioid Withdrawal Syndrome Prolonged use of belladonna and opium suppositories during pregnancy can result in withdrawal in the neonate. Neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, 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 [ see Use in Specific Populations (8.1), Patient Counseling Information ]. 5.4 Risks from Concomitant Use with Alcohol, Benzodiazepines or Other Central Nervous System Depressants Profound sedation, respiratory depression, coma, and death may result from the concomitant use of belladonna and opium suppositories with benzodiazepines or other CNS depressants (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol). Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioid analgesics alone. Because of similar pharmacological properties, it is reasonable to expect similar risk with the concomitant use of other CNS depressant drugs with opioid analgesics [ see Drug Interactions (7) ]. If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response. If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response. Follow patients closely for signs and symptoms of respiratory depression and sedation. Advise both patients and caregivers about the risks of respiratory depression and sedation when belladonna and opium suppositories are used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy machinery until the effects of concomitant use of the benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death associated with the use of additional CNS depressants including alcohol and illicit drugs [ see Drug Interactions (7) and Patient Counseling Information (17) ]. 5.5 Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients The use of belladonna and opium suppositories in patients with acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment is contraindicated. Patients with Chronic Pulmonary Disease : belladonna and opium suppositories-treated patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression are at increased risk of decreased respiratory drive including apnea, even at recommended dosages of belladonna and opium suppositories [ see Warnings and Precautions (5.2) ]. Elderly, Cachetic, or Debilitated Patients : Life-threatening respiratory depression is more likely to occur in elderly, cachectic, or debilitated patients because they may have altered pharmacokinetics or altered clearance compared to younger, healthier patients [ see Warnings and Precautions (5.2) ]. Monitor such patients closely, particularly when initiating and titrating belladonna and opium suppositories and when belladonna and opium suppositories is given concomitantly with other drugs that depress respiration [ see Warnings and Precautions (5.2) ]. Alternatively, consider the use of non-opioid analgesics in these patients. 5.6 Interactions with Monoamine Oxidase Inhibitors Monoamine oxidase inhibitors (MAOIs) may potentiate the effects of opioids, including respiratory depression, coma, and confusion. Belladonna and Opium Suppositories should not be used in patients taking MAOIs or within 14 days of stopping such treatment. 5.7 Adrenal Insufficiency Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Presentation of adrenal insufficiency may include non-specific symptoms and signs including nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers. Other opioids may be tried as some cases reported use of a different opioid without recurrence of adrenal insufficiency. The information available does not identify any particular opioids as being more likely to be associated with adrenal insufficiency. 5.8 Severe Hypotension Belladonna and opium suppositories may cause severe hypotension including orthostatic hypotension and syncope in ambulatory patients. There is increased risk in patients whose ability to maintain blood pressure has already been compromised by a reduced blood volume or concurrent administration of certain CNS depressant drugs (e.g., phenothiazines or general anesthetics) [ see Drug Interactions (7) ]. Monitor these patients for signs of hypotension after initiating or titrating the dosage of belladonna and opium suppositories. In patients with circulatory shock, belladonna and opium suppositories may cause vasodilation that can further reduce cardiac output and blood pressure. Avoid the use of belladonna and opium suppositories in patients with circulatory shock. 5.9 Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness In patients who may be susceptible to the intracranial effects of CO 2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), belladonna and opium suppositories may reduce respiratory drive, and the resultant CO 2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with belladonna and opium suppositories. Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of belladonna and opium suppositories in patients with impaired consciousness or coma. 5.10 Risks of Use in Patients with Gastrointestinal Conditions Belladonna and opium suppositories are contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus. The opium in belladonna and opium suppositories may cause spasm of the sphincter of Oddi. Opioids may cause increases in serum amylase. Monitor patients with biliary tract disease, including acute pancreatitis, for worsening symptoms. 5.11 Increased Risk of Seizures in Patients with Seizure Disorders The opium in belladonna and opium suppositories may increase the frequency of seizures in patients with seizure disorders, and may increase the risk of seizures occurring in other clinical settings associated with seizures. Monitor patients with a history of seizure disorders for worsened seizure control during belladonna and opium suppositories therapy. 5.12 Withdrawal Avoid the use of mixed agonist/antagonist (e.g., pentazocine, nalbuphine, and butorphanol) or partial agonist (e.g., buprenorphine) analgesics in patients who are receiving a full opioid agonist analgesic, including belladonna and opium suppositories. In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or precipitate withdrawal symptoms [ see Drug Interactions (7) ]. When discontinuing belladonna and opium suppositories, gradually taper the dosage [ see Dosage and Administration (2.4) ]. Do not abruptly discontinue belladonna and opium suppositories [ see Drug Abuse and Dependence (9.3) ]. 5.13 Risks of Driving and Operating Machinery Belladonna and opium suppositories may impair the mental or physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of belladonna and opium suppositories and know how they will react to the medication [see Patient Counseling Information (17)].
