- RMS® Suppository¶
Morphine rectal may be habit forming, especially with prolonged use. Use morphine exactly as directed. Do not use more of it, use it more often, or use it in a different way than directed by your doctor. While you are using morphine rectal, discuss with your health care provider your pain treatment goals, length of treatment, and other ways to manage your pain. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse morphine if you have or have ever had any of these conditions. Talk to your health care provider immediately and ask for guidance if you think that you have an opioid addiction or call the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 1-800-662-HELP.
Morphine may increase the risk that you will experience breathing problems or other serious or life-threatening breathing problems, sedation, or coma if used along with certain medications. Tell your doctor if you are taking or plan to take any of the following medications: benzodiazepines such as alprazolam (Xanax), diazepam (Diastat, Valium), estazolam, flurazepam, lorazepam (Ativan), and triazolam (Halcion); medications for mental illness, nausea, or pain; muscle relaxants; sedatives; sleeping pills; or tranquilizers. Your doctor may need to change the dosages of your medications and will monitor you carefully. If you use morphine rectal with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.
Drinking alcohol, taking prescription or nonprescription medications that contain alcohol, or using street drugs during your treatment with morphine rectal increases the risk that you will experience these serious, life-threatening side effects. Do not drink alcohol, take prescription or nonprescription medications that contain alcohol, or use street drugs during your treatment.
Talk to your doctor about the risks of using morphine rectal.
WHY is this medicine prescribed?
Morphine rectal is used to relieve moderate to severe pain. Morphine is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the body senses pain.
HOW should this medicine be used?
Morphine rectal comes as a suppository to insert in the rectum. It is usually inserted every 4 hours. Use rectal morphine at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use morphine exactly as directed.
Your doctor may adjust your dose of morphine during your treatment to control your pain as well as possible. If you feel that your pain is not controlled, call your doctor. Do not change the dose of your medication without talking to your doctor.
Do not stop using morphine without talking to your doctor. Your doctor may decrease your dose gradually. If you suddenly stop using morphine, you may experience withdrawal symptoms such as anxiety; sweating; difficulty falling asleep or staying asleep; chills; shaking of a part of your body that you cannot control; nausea; diarrhea; runny nose, sneezing or coughing; hair on your skin standing on end; or hallucinating (seeing things or hearing voices that do not exist).
To use the suppositories, follow these steps:
- Remove the wrapper.
- Dip the tip of the suppository in water.
- Lie down on your left side and raise your right knee to your chest (a left-handed person should lie on the right side and raise the left knee.)
- Using your finger, insert the suppository about 1 inch (2.5 centimeters) into the rectum.
- Hold it in place with your finger for a few moments
- Stand up after about 15 minutes. Wash your hands thoroughly and resume normal activities.
Are there OTHER USES for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
What should I do in case of OVERDOSE?
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at Web Site. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
While you are using morphine, you may be told to always have a rescue medication called naloxone available (e.g., home, office). Naloxone is used to reverse the life-threatening effects of an overdose. It works by blocking the effects of opiates to relieve dangerous symptoms caused by high levels of opiates in the blood. You will probably be unable to treat yourself if you experience an opiate overdose. You should make sure that your family members, caregivers, or the people who spend time with you know how to tell if you are experiencing an overdose, how to use naloxone, and what to do until emergency medical help arrives. Your doctor or pharmacist will show you and your family members how to use the medication. Ask your pharmacist for the instructions or visit the manufacturer's website to get the instructions. If someone sees that you are experiencing symptoms of an overdose, he or she should give you your first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives. Your symptoms may return within a few minutes after you receive naloxone. If your symptoms return, the person should give you another dose of naloxone. Additional doses may be given every 2 to 3 minutes, if symptoms return before medical help arrives.
Symptoms of overdose may include the following:
- slow, shallow, or irregular breathing
- blue or purple color to the skin
- loss of consciousness
- limp muscles
- cold, clammy skin
- slow heartbeat
- blurred vision
What OTHER INFORMATION should I know?
Keep all appointments with your doctor and laboratory. Your doctor may order certain lab tests to check your body's response to morphine.
Before having any laboratory test (especially those that involve methylene blue), tell your doctor and the laboratory personnel that you are using morphine rectal.
This prescription is not refillable. If you are using morphine to control your pain on a long-term basis, be sure to schedule appointments with your doctor so that you do not run out of medication. If you are using morphine on a short term basis, call your doctor if you continue to experience pain after you finish the medication.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
