What is Arymo ER?
Arymo ER is an opioid medication used to treat moderate to severe pain. Short-acting this medicine is taken as needed for pain.
The extended-release form of morphine is for around-the-clock treatment of pain. This form of morphine is not for use on an as-needed basis for pain.
Arymo ER may also be used for purposes not listed in this medication guide.
MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.
Taking opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use opioid medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not take Arymo ER if you have ever had an allergic reaction to Arymo ER or other narcotic medicines, or if you have:
severe asthma or breathing problems; or
a blockage in your stomach or intestines.
Do not use Arymo ER if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.
Tell your doctor if you have ever had:
a drug or alcohol addiction, or mental illness;
liver or kidney disease; or
problems with your gallbladder, pancreas, or thyroid.
If you use opioid medicine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on opioids may need medical treatment for several weeks.
Do not breast-feed while taking morphine. This medicine can pass into breast milk and cause drowsiness, breathing problems, or death in a nursing baby.
How should I use Arymo ER?
Follow the directions on your prescription label and read all medication guides. Never use Arymo ER in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of this medicine.
Never share opioid medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it. Selling or giving away opioid medicine is against the law.
Stop taking all other around-the-clock narcotic pain medications when you start taking Arymo ER.
Swallow the capsule or tablet whole to avoid exposure to a potentially fatal overdose. Do not crush, chew, break, open, or dissolve.
Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Do not stop using Arymo ER suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
Never crush or break a Arymo ER pill to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death with the misuse of morphine and similar prescription drugs.
Store at room temperature, away from heat, moisture, and light. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.
Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.
What happens if I miss a dose?
Arymo ER is sometimes taken only once per day, and sometimes 2 or 3 times per day. Since Arymo ER is used for pain, you are not likely to miss a dose. If you do miss a dose, take the medicine as soon as you remember. Then take your next dose as follows:
If you take Arymo ER 3 times per day: Take your next dose 8 hours after taking the missed dose.
If you take Arymo ER 2 times per day: Take your next dose 12 hours after taking the missed dose.
If you take Arymo ER 1 time per day: Take your next dose 24 hours after taking the missed dose.
Do not take two doses at one time. Do not take more than your prescribed dose in a 24-hour period.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A Arymo ER overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include slow heart rate, severe drowsiness, muscle weakness, cold and clammy skin, pinpoint pupils, very slow breathing, or coma.
What should I avoid while using Arymo ER?
Do not drink alcohol. Dangerous side effects or death could occur.
Avoid driving or hazardous activity until you know how Arymo ER will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries.
Arymo ER side effects
Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Opioid medicine can slow or stop your breathing, and death may occur. A person caring for you should seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.
Call your doctor at once if you have:
slow heart rate, sighing, weak or shallow breathing;
chest pain, fast or pounding heartbeats;
extreme drowsiness, feeling like you might pass out; or
Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
Serious side effects may be more likely in older adults and those who are malnourished or debilitated.
Long-term use of opioid medication may affect fertility (ability to have children) in men or women. It is not known whether opioid effects on fertility are permanent.
Common side effects may include:
drowsiness, dizziness, tiredness;
constipation, stomach pain, nausea, vomiting;
feelings of extreme happiness or sadness.
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.
What other drugs will affect Arymo ER?

other narcotic medications--opioid pain medicine or prescription cough medicine;
drugs that make you sleepy or slow your breathing--a sleeping pill, muscle relaxer, tranquilizer, antidepressant, or antipsychotic medicine; or
