Morphine Sulfate Information:

What is morphine sulfate?

Morphine sulfate is the generic name for this opiate analgesic narcotic drug. It functions as an agonist at the mu-opioid. An agonist is a drug or chemical substance capable of activating a receptor to induce a full or partial physiological response. Morphine sulfate works by activating the opiate receptors in the brain and blocking pain signals. It also acts as a central nervous system depressant. Morphine is primarily derived as a chemical extraction from opium from the poppy plant. It is a highly addictive substance and should be used with caution. 

How do I take morphine sulfate?

Morphine sulfate comes as a tablet or a liquid to be taken orally. If taking liquid morphine sulfate, use a measuring device that is specifically for measuring medication and not a kitchen spoon or other device to measure your dose. This medication is usually taken every four hours or just enough to keep the pain under control. Follow instructions given to you by your doctor and never take more than prescribed. After pain has been controlled, your doctor can begin to reduce your dose. Drinking lots of fluids is recommended to reduce the side effect of constipation.

Initial treatment with morphine may cause the patient to sleep for many hours. This is sometimes simply the result of the patient’s need to sleep after experiencing so many hours of pain without relief and is not due to the side effects of the drug itself.

Before taking morphine sulfate, tell your doctor if:

  • You have a history of drug or alcohol abuse.
  • You regularly drink alcoholic beverages.
  • You are allergic to narcotic medications or any of the other ingredients in morphine sulfate.
  • You have ever sustained a serious head injury or had a brain tumor.
  • You have seizures.
  • You have an enlarged prostate or trouble urinating.
  • You have kidney, liver, pancreas, or gallbladder disease.
  • You have low blood pressure or an irregular heartbeat.
  • You have asthma, COPD, lung disease, or breathing problems.
  • You are pregnant or breast-feeding.
  • You have scoliosis or an underactive thyroid.
  • You have an intestinal blockage or other intestinal problems.
  • You are taking prescription or nonprescription drugs, vitamins or supplements, especially other narcotics, sedatives or sleeping pills, antihistamines, barbiturates, muscle relaxants, blood thinners, beta blockers, diuretics or water pills, MAO inhibitors, and any other pain killers.

What are the possible side effects of taking morphine sulfate?

Side effects from taking morphine sulfate include constipation, nausea, dizziness, drowsiness, dry mouth, sweating, vomiting, constricted pupils, and euphoria. Serious side effects include a change in heart rate, seizures, respiratory depression, blue or purplish skin color, swelling, fainting, chest pain, confusion, and difficulty swallowing. If you experience any of these side effects, call your doctor immediately.


What if I forget to take a dose of morphine sulfate?

If you are taking this medication regularly, take the missed dose as soon as your remember it. If it’s almost time for your next dose, skip the missed dose and continue on your regular schedule. Never take a double dose or consecutive doses of morphine sulfate to compensate for a missed one.

How do I store morphine sulfate?

Store morphine sulfate tightly closed in a child-proof container at a room temperature between 59 and 86 degrees Fahrenheit. Keep this medication away from children and pets. It can cause serious respiratory depression. Also keep it out of reach of anyone prone to drug or alcohol abuse.

What happens if I overdose on morphine sulfate?

Signs of morphine overdose include respiratory depression or slowed, shallow breathing, extreme sleepiness or coma, weakness, cold or clammy skin, and low blood pressure. If you think you or someone you know has overdosed on morphine sulfate, call 911 or get the victim to a hospital as soon as possible. Try to keep the airways open.


Do not drink alcoholic beverages while taking morphine sulfate. This increases the chance of dangerous side effects and overdose. This medication is highly addictive. The minimum dosage should be used to achieve pain relief. Alternative medications should be considered for those who are prone to drug abuse. Due to risk of respiratory depression, lower dosages should be considered for the elderly.
