⚠ Boxed Warning (Black Box)
WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF MORPHINE SULFATE TABLETS Addiction, Abuse, and Misuse Because the use of morphine sulfate tablets exposes 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 and reassess all patients regularly for the development of these behaviors and conditions [see Warnings and Precautions ( 5.1 )]. Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression may occur with use of morphine sulfate tablets, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of morphine sulfate tablets are essential [see Warnings and Precautions ( 5.2 )]. Accidental Ingestion Accidental ingestion of even one dose of morphine sulfate tablets, especially by children, can result in a fatal overdose of morphine [see Warnings and Precautions ( 5.2 )] . Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of morphine sulfate tablets and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate [see Warnings and Precautions ( 5.3 ), Drug Interactions ( 7 )]. Neonatal Opioid Withdrawal Syndrome (NOWS) If opioid use is required for an extended period of time in a pregnant woman, advise the patient of the risk of NOWS, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery [see Warnings and Precautions ( 5.4 )]. Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS) Healthcare providers are strongly encouraged to complete a REMS-compliant education program and to counsel patients and caregivers on serious risks, safe use, and the importance of reading the Medication Guide with each prescription [see Warnings and Precautions ( 5.5 )].

Description
11 DESCRIPTION Morphine sulfate tablets are an opioid agonist, available in 15 mg and 30 mg for oral administration: 15 mg tablet: Each tablet contains 15 mg morphine sulfate, USP (equivalent to 11.25 mg morphine). 30 mg tablet: Each tablet contains 30 mg morphine sulfate, USP (equivalent to 22.5 mg morphine). Chemically, morphine sulfate is 7,8-didehydro-4,5α-epoxy-17-methylmorphinan-3,6α-diol sulfate (2:1) (salt) pentahydrate. Morphine sulfate, USP is a white to off-white crystalline solid. It is soluble in water and slightly soluble in alcohol, but is practically insoluble in chloroform. The octanol:water partition coefficient of morphine is 1.42 at physiologic pH and the pka is 7.9 for the tertiary nitrogen (the majority is ionized at pH 7.4). Its molecular formula is (C 17 H 19 NO 3 ) 2
What Is Morphine Used For?
1 INDICATIONS AND USAGE Morphine sulfate tablets are indicated for the management of: adult and pediatric patients weighing at least 50 kg and above with acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. adults with chronic pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Limitations of Use: Because of the risks of addiction, abuse, and misuse with opioids, which can occur at any dosage or duration, [see Warnings and Precautions ( 5.1 )], reserve morphine sulfate tablets for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or opioid combination products): Have not been tolerated or are not expected to be tolerated, Have not provided adequate analgesia or are not expected to provide adequate analgesia Morphine sulfate tablets should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate. Morphine sulfate tablets are opioid agonists indicated for the management of: adults and pediatric patients weighing 50 kg and above with acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. adults with chronic pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Limitations of Use ( 1 ) Because of the risks of addiction, abuse, and misuse with opioids, which can occur at any dosage or duration ( 5.1 ), reserve morphine sulfate tablets for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or opioid combination products): Have not been tolerated or are not expected to be tolerated, Have not provided adequate analgesia or are not expected to provide adequate analgesia Morphine sulfate tablets should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate.
Dosage and Administration
2 DOSAGE AND ADMINISTRATION Morphine sulfate tablets should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. ( 2.1 ) Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Reserve titration to higher doses of morphine sulfate tablets for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. ( 2.1 , 5 ) Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available. ( 2.1 ) Initiate the dosing regimen for each patient individually, taking into account the patient’s underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse. ( 2.1 , 5.1 ) Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with morphine sulfate tablets. Consider this risk when selecting an initial dose and when making dose adjustments. ( 2.1 , 5.2 ) Discuss availability of naloxone with the patient and caregiver and assess each patient’s need for access to naloxone, both when initiating and renewing treatment with morphine sulfate tablets. Consider prescribing naloxone based on the patient’s risk factors for overdose. ( 2.2 , 5.1 , 5.2 , 5.3 ) Initiate treatment with morphine sulfate tablets in adults and pediatric patients 50 kg and above: 15 to 30 mg every 4 hours as needed for pain, at the lowest dose necessary to achieve adequate analgesia. Do not exceed 30 mg as an initial dose in pediatric patients. Titrate the dose based upon the individual patient’s response to their initial dose of morphine sulfate tablets ( 2.3 , 2.4 ) Do not abruptly discontinue morphine sulfate tablets in a physically dependent patient because rapid discontinuation of opioid analgesics has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. ( 2.5 , 5.14 ) 2.1 Important Dosage and Administration Instructions Morphine sulfate tablets should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals [see Warnings and Precautions ( 5 )]. Because the risk of overdose increases as opioid doses increase, reserve titration to higher doses of morphine sulfate tablets for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. Many acute pain conditions (e.g., the pain that occurs with a number of...
Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following serious adverse reactions are described, or described in greater detail, in other sections: Addiction, Abuse, and Misuse [see Warnings and Precautions ( 5.1 )] Life-Threatening Respiratory Depression [see Warnings and Precautions ( 5.2 )] Interactions with Benzodiazepine or Other CNS Depressants [see Warnings and Precautions ( 5.3 )] Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions ( 5.4 )] Opioid-Induced Hyperalgesia and Allodynia [see Warnings and Precautions ( 5.6 )] Adrenal Insufficiency [see Warnings and Precautions ( 5.9 )] Severe Hypotension [see Warnings and Precautions ( 5.10 )] Gastrointestinal Adverse Reactions [see Warnings and Precautions ( 5.12 )] Seizures [see Warnings and Precautions ( 5.13 )] Withdrawal [see Warnings and Precautions ( 5.14 )] The following adverse reactions associated with the use of morphine were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Serious adverse reactions associated with morphine use included: respiratory depression, apnea, and to a lesser degree, circulatory depression, respiratory arrest, shock and cardiac arrest. The common adverse reactions seen on initiation of therapy with morphine in adults were dose-dependent and were typical opioid-related adverse reactions. The most frequent of these included: constipation, nausea, and somnolence. Other commonly observed adverse reactions included: lightheadedness, dizziness, sedation, vomiting, and sweating. The frequency of these events depended upon several factors including clinical setting, the patient’s level of opioid tolerance, and host factors specific to the individual. Other less frequently observed adverse reactions from opioid analgesics, including morphine sulfate included: Body as a Whole: malaise, withdrawal syndrome Cardiovascular System: bradycardia, hypertension, hypotension, palpitations, syncope, tachycardia Digestive System: biliary pain, dyspepsia, dysphagia, gastroenteritis, abnormal liver function tests, rectal disorder, thirst Endocrine : hypogonadism Hemic and Lymphatic System : anemia, thrombocytopenia Metabolic and Nutritional Disorders : edema, weight loss Musculoskeletal : skeletal muscle rigidity, decreased bone mineral density Nervous System : abnormal dreams, abnormal gait, agitation, amnesia, anxiety, ataxia, confusion, convulsions, coma, delirium, depression, dry mouth, euphoria, hallucinations, lethargy, nervousness, abnormal thinking, tremor, vasodilation, vertigo, headache Respiratory System : hiccup, hypoventilation, voice alteration Skin and Appendages : dry skin, urticaria, pruritus Special Senses : amblyopia, eye pain, taste perversion Urogenital System: abnormal ejaculation, dysuria, impotence, decreased libido, oliguria, urinary retention or hesitancy, anti-diuretic effect, amenorrhea Serotonin Syndrome : Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs. Adrenal Insufficiency : Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Anaphylaxis : Anaphylaxis has been reported with ingredients contained in morphine sulfate tablets. Androgen Deficiency: Cases of androgen deficiency have occurred with chronic use of opioids for an extended period of time. [see Clinical Pharmacology ( 12.2 )]. Hyperalgesia and Allodynia: Cases of hyperalgesia and allodynia have been reported with opioid therapy of any duration [see Warnings and Precautions ( 5.6 )] Hypoglycemia: Cases of hypoglycemia have been reported in patients taking opioids. Most reports were in patients with at least one predisposing risk factor (e.g., diabetes). Clinical Trial Experience in Pediatric Patients The...
Drug Interactions
7 DRUG INTERACTIONS Table 1 includes clinically significant drug interactions with morphine sulfate tablets. Table 1: Clinically Significant Drug Interactions with Morphine sulfate tablets Benzodiazepines and Other Central Nervous System (CNS) Depressants Clinical Impact: Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death [see Warnings and Precautions ( 5.3 )]. Intervention: Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Inform patients and caregivers of this potential interaction and educate them on the signs and symptoms of respiratory depression (including sedation). If concomitant use is warranted, consider prescribing naloxone for the emergency treatment of opioid overdose [see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.1 , 5.2 , 5.3 )]. Examples: Benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol. Serotonergic Drugs Clinical Impact: The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome. Intervention: If concomitant use is warranted, frequently evaluate the patient, particularly during treatment initiation and dose adjustment. Discontinue morphine sulfate tablets if serotonin syndrome is suspected. Examples: Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that effect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), certain muscle relaxants (i.e., cyclobenzaprine, metaxalone), monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue). Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact: MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity (e.g., respiratory depression, coma) [see Warnings and Precautions ( 5.8 )]. Intervention: Do not use morphine sulfate tablets in patients taking MAOIs or within 14 days of stopping such treatment. Examples: Phenelzine, tranylcypromine, linezolid. Mixed Agonist/Antagonist and Partial Agonist Opioid Analgesics Clinical Impact: May reduce the analgesic effect of morphine sulfate tablets and/or precipitate withdrawal symptoms. Intervention: Avoid concomitant use. Examples: Butorphanol, nalbuphine, pentazocine, buprenorphine. Muscle Relaxants Clinical Impact: Morphine may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression. Intervention: Because respiratory...
Contraindications
4 CONTRAINDICATIONS Morphine sulfate tablets are contraindicated in patients with: Significant respiratory depression [see Warnings and Precautions ( 5.2 )]. Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see Warnings and Precautions ( 5.7 )]. Concurrent use of monoamine oxidase inhibitors (MAOIs) or use of MAOIs within the last 14 days [see Warnings and Precautions (5.8) and Drug Interactions ( 7 )]. Known or suspected gastrointestinal obstruction, including paralytic ileus [see Warnings and Precautions ( 5.12 )]. Hypersensitivity to morphine (e.g., anaphylaxis) [see Adverse Reactions ( 6 )]. Significant respiratory depression. ( 4 ) Acute or severe bronchial asthma in an unmonitored setting or in absence of resuscitative equipment. ( 4 ) Concurrent use of monoamine oxidase inhibitors (MAOIs) or use of MAOIs within the last 14 days. ( 4 ) Known or suspected gastrointestinal obstruction, including paralytic ileus. ( 4 ) Hypersensitivity to morphine. ( 4 )
Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary: U se of opioid analgesics for an extended period of time during pregnancy can cause neonatal opioid withdrawal syndrome [see Warnings and Precautions ( 5.4 )] . There are no available data with morphine sulfate tablets in pregnant women to inform a drug-associated risk for major birth defects and miscarriage. Published studies with morphine use during pregnancy have not reported a clear association with morphine and major birth defects [see Human Data] . In published animal reproduction studies, morphine administered subcutaneously during the early gestational period produced neural tube defects (i.e., exencephaly and cranioschisis) at 5 and 16 times the human daily dose of 60 mg based on body surface area (HDD) in hamsters and mice, respectively, lower fetal body weight and increased incidence of abortion at 0.4 times the HDD in the rabbit, growth retardation at 6 times the HDD in the rat, and axial skeletal fusion and cryptorchidism at 16 times the HDD in the mouse. Administration of morphine sulfate to pregnant rats during organogenesis and through lactation resulted in cyanosis, hypothermia, decreased brain weights, pup mortality, decreased pup body weights, and adverse effects on reproductive tissues at 3 to 4 times the HDD; and long-term neurochemical changes in the brain of offspring which correlate with altered behavioral responses that persist through adulthood at exposures comparable to and less than the HDD [see Animal Data] . Based on animal data, advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations: Fetal/Neonatal Adverse Reactions: Use...
Overdosage
10 OVERDOSAGE Clinical Presentation Acute overdose with morphine can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, hypoglycemia, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations [see Clinical Pharmacology ( 12.2 )]. Treatment of Overdose In case of overdose, priorities are the reestablishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support measures. Opioid antagonists, such as naloxone, are specific antidotes to respiratory depression resulting from opioid overdose. For clinically significant respiratory or circulatory depression secondary to opioid overdose, administer an opioid antagonist. Because the duration of opioid reversal is expected to be less than the duration of action of morphine in morphine sulfate tablets, carefully monitor the patient until spontaneous respiration is reliably reestablished. If the response to an opioid antagonist is suboptimal or only brief in nature, administer additional antagonist as directed by the product’s prescribing information. In an individual physically dependent on opioids, administration of the recommended usual dosage of the antagonist will precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. If a decision is made to treat serious respiratory depression in the physically dependent patient, administration of the antagonist should be initiated with care and by...
