Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

high levels of serotonin in the body--agitation, hallucinations, fever, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, diarrhea; or

low cortisol levels-- nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.

Serious breathing problems may be more likely in older adults and people who are debilitated or have wasting syndrome or chronic breathing disorders.

Common side effects of morphine may include:

breathing problems;

drowsiness, dizziness;

constipation, nausea, vomiting;

sweating; or

numbness, tingling, or cold feeling in your hands and feet.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Relate drugs

How to use Morphine injection

Follow the directions on your prescription label and read all medication guides or instruction sheets. Never use morphine in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to use more of morphine.

Never share opioid medicine with another person, especially someone with a history of drug addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medicine where others cannot get to it. Selling or giving away this medicine is against the law.

Morphine is injected into a muscle or a vein. Morphine injection is sometimes given with an infusion pump that controls your dosing.

You may have withdrawal symptoms if you stop using morphine suddenly. Ask your doctor before stopping the medicine.

Store at room temperature away from moisture and heat. Keep the auto-injector in its original container until you are ready to use it.

Keep your medicine in a place where no one can use it improperly.

Do not keep leftover medicine. Just one dose can cause death in someone using it accidentally or improperly. Ask your pharmacist about a drug take-back program, or flush the unused medicine down the toilet.

Warnings

MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep morphine where others cannot get to it.

Using opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.

Fatal side effects may occur if you also drink alcohol or use other drugs that cause drowsiness or slow breathing.
