Morphine Sulfate CR Oral Uses
This medication is used to treat severe pain. Morphine is a narcotic pain reliever. It acts on certain centers in the brain to give you pain relief.
How To Use Morphine Sulfate CR Oral
Take this medication by mouth with or without food, usually every 4 hours. Use exactly as prescribed by your doctor.
If you are taking the liquid, measure the correct dose using the medication measuring device provided. Do not use a household spoon. Be careful not to confuse the dose of morphine liquid in milligrams (mg) with the dose in milliliters (mL). Morphine liquid comes in several strengths. Be sure that you get the correct strength each time you refill your prescription.
If you have nausea, you may take this drug with food, although this may cause your body to absorb less of the drug and get less benefit from it. Consult your doctor or pharmacist about other ways to decrease nausea (e.g., antihistamines, lying down for 1-2 hours with as little head movement as possible).
The dosage is based on your medical condition and response to treatment. Pain medications work best if they are used when the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.
This medication may cause dependence, especially if it has been used regularly for an extended time or if it has been used in high doses. In such cases, withdrawal reactions (e.g., shakiness, sweating, nausea) may occur if you suddenly stop this drug. To prevent withdrawal reactions when stopping extended, regular treatment with this drug, gradually reduce the dosage as directed. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.
Though very unlikely, abnormal drug-seeking behavior (addiction) is possible with this medication. Do not increase your dose, take it more frequently, or take it for a longer time than prescribed. Properly stop the medication when so directed.
When used for an extended period, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well.
Tell your doctor if your pain persists or worsens after 24 hours when first starting this medication or after a dose change.
