What is morphine (Avinza, Kadian, Morphine IR, MS Contin, MSIR, Oramorph SR, Roxanol)?

Morphine is in a group of drugs called narcotic pain relievers.

Morphine is used to treat moderate to severe pain. Short-acting morphine is taken as needed for pain. Extended-release morphine is for use when around-the-clock pain relief is needed.

Morphine is not for treating pain just after surgery unless you were already taking morphine before the surgery.

Morphine may also be used for purposes other than those listed in this medication guide.

What are the possible side effects of morphine?

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

Call your doctor at once if you have any of these serious side effects:

• shallow breathing, slow heartbeat;
• seizure (convulsions);
• cold, clammy skin;
• confusion;
• severe weakness or dizziness; or
• feeling light-headed, fainting.

Less serious side effects are more likely to occur, such as:

• constipation;
• warmth, tingling, or redness under your skin;
• nausea, vomiting, stomach pain, diarrhea, loss of appetite;
• dizziness, headache, anxiety;
• memory problems; or
• sleep problems (insomnia).

This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about morphine?

You may not be able to take this medicine unless you are already being treated with a similar opioid pain medicine and your body is tolerant to it. Talk with your doctor if you are not sure you are opioid-tolerant.

Morphine may be habit-forming and should be used only by the person it was prescribed for. Morphine should never be given to another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.

Do not drink alcohol while you are using morphine. Dangerous side effects or death can occur when alcohol is combined with morphine. Check your food and medicine labels to be sure these products do not contain alcohol.

Never take more than your prescribed dose of morphine. Tell your doctor if the medicine seems to stop working as well in relieving your pain.

Do not stop taking morphine suddenly, or you could have unpleasant withdrawal symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication.
