What is morphine?
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.

Precautions
Do not use this medication if you have ever had an allergic reaction to a narcotic medicine (examples include codeine, methadone, Oxycontin, Darvocet, Percocet, Vicodin, Lortab, and many others). You should also not take morphine if you are having an asthma attack or if you have a bowel obstruction called paralytic ileus.
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.
Before using morphine, tell your doctor if you are allergic to any drugs, or if you have:
- asthma, COPD, sleep apnea, or other breathing disorders;
- liver or kidney disease;
- underactive thyroid;
- curvature of the spine;
- a history of head injury or brain tumor;
- epilepsy or other seizure disorder;
- low blood pressure;
- gallbladder disease;
- Addison's disease or other adrenal gland disorders;
- enlarged prostate, urination problems;
- mental illness; or
- a history of drug or alcohol addiction.
You may not be able to take morphine 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 can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Older adults may be more sensitive to the effects of this medicine.
Do not drink alcohol while you are taking this medication. 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.

Instructions
Seek emergency medical attention if you think you have used too much of this medicine. An overdose of morphine can be fatal.
Overdose symptoms may include extreme drowsiness, pinpoint pupils, confusion, cold and clammy skin, weak pulse, shallow breathing, fainting, or breathing that stops.
Since morphine is sometimes used as needed, you may not be on a dosing schedule. If you are using the medication regularly, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.
Extended-release morphine is not for use on an as-needed basis for pain.

Interactions
Avoid taking morphine if you have used an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 14 days. Side effects can be more severe if you use morphine before the MAO inhibitor has cleared from your body.
Do not take morphine with other narcotic pain medications, sedatives, tranquilizers, muscle relaxers, or other medicines that can make you sleepy or slow your breathing. Dangerous side effects may result.
Before taking morphine, tell your doctor if you are using pentazocine (Talwin), nalbuphine (Nubain), butorphanol (Stadol), or buprenorphine (Buprenex, Subutex). If you are using any of these drugs, you may not be able to use morphine, or you may need dosage adjustments or special tests during treatment.
This list is not complete and there may be other drugs that can interact with morphine. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
