Morphine is a prescription pain medication belonging to a group of drugs called opioid narcotics. Opoid narcotics bind to receptors throughout the body which works to relieve moderate to severe pain.
Morphine is the active ingredient of a variety of medications found in many different forms, including tablets, extended-release tablets or capsules, oral solution, or injectable solution.
Extended-release forms are used for pain that is expected to persist for an extended period of time.
Rectal morphine comes as a suppository to insert in the rectum, usually every 4 hours.
Common side effects of morphine include constipation, nausea, itchiness, and sleepiness. Do not drink alcohol or any foods or medications containing alcohol while taking morphine as alcohol increases the risk that you will experience breathing problems or other serious, life-threatening side effects.

Rms FDA Warning
WARNING: RISK OF MEDICATION ERRORS
Morphine sulfate oral solution is available in the 100 mg per 5 mL (20 mg/mL) concentration and is indicated for use in opioid-tolerant patients only.
Take care when prescribing and administering morphine sulfate oral solution to avoid dosing errors due to confusion between different concentrations and between mg and mL, which could result in accidental overdose and death. Take care to ensure the proper dose is communicated and dispensed.
Keep morphine sulfate oral solution out of the reach of children. In case of accidental ingestion, seek emergency medical help immediately.
WARNING: ABUSE POTENTIAL, LIFE-THREATENING RESPIRATORY DEPRESSION, and ACCIDENTAL EXPOSURE
Morphine sulfate extended-release tablets contain morphine, an opioid agonist and Schedule II controlled substance with an abuse liability similar to other opioid agonists, legal or illicit. Assess each patient’s risk for opioid abuse or addiction prior to prescribing morphine sulfate extended-release tablets. The risk for opioid abuse is 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 depressive disorder). Routinely monitor all patients receiving morphine sulfate extended-release tablets for signs of misuse, abuse, and addiction during treatment.
Life-Threatening Respiratory Depression
Respiratory depression, including fatal cases, may occur with use of morphine sulfate extended-release tablets, even when the drug has been used as recommended and not misused or abused. Proper dosing and titration are essential and morphine sulfate extended-release tablets should only be prescribed by healthcare professionals who are knowledgeable in the use of potent opioids for the management of chronic pain. Monitor for respiratory depression, especially during initiation of morphine sulfate extended-release tablets or following a dose increase. Instruct patients to swallow morphine sulfate extended-release tablets whole. Crushing, dissolving, or chewing the tablet can cause rapid release and absorption of a potentially fatal dose of morphine.
Accidental Exposure-Accidental ingestion of morphine sulfate extended-release tablets, especially in children, can result in a fatal overdose of morphine.
WARNING: Avinza Capsules
AVINZA capsules are a modified-release formulation of morphine sulfate indicated for once daily administration for the relief of moderate to severe pain requiring continuous, around-the-clock opioid therapy for an extended period of time. AVINZA CAPSULES ARE TO BE SWALLOWED WHOLE OR THE CONTENTS OF THE CAPSULES SPRINKLED ON APPLESAUCE. THE CAPSULE BEADS ARE NOT TO BE CHEWED, CRUSHED, OR DISSOLVED DUE TO THE RISK OF RAPID RELEASE AND ABSORPTION OF A POTENTIALLY FATAL DOSE OF MORPHINE. PATIENTS MUST NOT CONSUME ALCOHOLIC BEVERAGES WHILE ON AVINZA THERAPY. ADDITIONALLY, PATIENTS MUST NOT USE PRESCRIPTION OR NON-PRESCRIPTION MEDICATIONS CONTAINING ALCOHOL WHILE ON AVINZA THERAPY. CONSUMPTION OF ALCOHOL WHILE TAKING AVINZA MAY RESULT IN THE RAPID RELEASE AND ABSORPTION OF A POTENTIALLY FATAL DOSE OF MORPHINE.
