What is morphine sulfate ER and how does it work?
Morphine sulfate ER (extended-release) is an opioid agonist analgesic that works at the mu-opioid receptors in the brain and spinal cord to change how the body senses and responds to pain. The "ER" means the medicine is released slowly over many hours, so a single dose provides continuous, around-the-clock relief rather than the quick, short-lived effect of an immediate-release tablet.
It is prescribed for moderate to severe pain that is bad enough to require daily, long-term opioid treatment when other options, such as non-opioid pain relievers or immediate-release opioids, are not enough. It is often used for chronic cancer pain and other ongoing pain that needs continuous therapy. It is not meant for as-needed (prn) pain. Because of the risks of addiction, abuse, misuse, and life-threatening breathing problems, it is reserved for patients for whom other treatments are ineffective, not tolerated, or otherwise inadequate.
Morphine sulfate ER cost and savings without insurance
Morphine sulfate ER is available as an FDA-approved generic, which usually makes it far less expensive than the brand-name versions. Even so, the cash price is not the same everywhere. Two pharmacies on the same street can quote very different prices for the identical tablet and strength, which is exactly why comparing before you fill matters.
Rx.com lets you compare the cash price and a free discount at more than 60,000 pharmacies, so you can see which nearby location is lowest today. There is no manufacturer copay or savings card for generic morphine sulfate ER, so the Rx.com discount is a straightforward way to help lower an out-of-pocket cost if you are paying without insurance or your plan does not cover it. Enter your ZIP above to see today's price. Because this is a Schedule II controlled substance, prescriptions cannot be refilled or transferred like other medicines, so it helps to know your best pharmacy option in advance.
Related long-acting opioids and brand equivalents
Morphine sulfate ER is the generic behind several brands. If your prescription is written for a specific brand, you can compare it directly: MS Contin and Kadian are both long-acting morphine products. Your prescriber may also consider other extended-release opioids depending on your situation.
- Morphine sulfate (immediate-release) for shorter-acting dosing
- Oxycodone ER and OxyContin
- Hydromorphone ER
- Fentanyl patch
- Tramadol ER
These are not interchangeable, and switching between opioids requires careful dose conversion by your prescriber. Never change or combine opioids on your own. Use the search above to compare prices on whichever one you are prescribed.
Important safety information
Morphine sulfate ER is a Schedule II controlled substance and carries an FDA Boxed Warning. It can lead to addiction, abuse, and misuse, which can result in overdose and death, and it can cause serious, life-threatening, or fatal slowed breathing (respiratory depression), especially when you first start it or after a dose increase. Tablets and capsules must be swallowed whole; crushing, chewing, or dissolving them can release a fatal dose all at once. Accidental swallowing, especially by a child, can be fatal, so store it securely. Prolonged use during pregnancy can cause neonatal opioid withdrawal syndrome, which can be life-threatening if not treated.
Combining morphine ER with benzodiazepines, alcohol, or other central nervous system depressants can cause extreme, potentially fatal sedation and breathing problems. Morphine is cleared mainly through glucuronidation in the liver rather than the CYP450 enzymes, so its most significant interactions are with other CNS depressants and with serotonergic medicines, which can raise the risk of serotonin syndrome, along with certain other drugs your prescriber and pharmacist will review. Other risks include adrenal insufficiency, severe low blood pressure, and added danger in people with head injury or increased pressure in the skull. Extended-release/long-acting opioids are subject to an FDA REMS program. This is not medical advice. Talk with your doctor or pharmacist about your full list of medicines and any questions before starting or stopping this medication.
