This medication is used to treat moderate to severe pain. Levorphanol is a narcotic pain reliever. It acts on certain centers in the brain to give you pain relief.
Take this medication by mouth, usually every 6 to 8 hours as needed or as directed by your doctor. You may take this drug with or without food. 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, age, response to treatment, and other medications that you may be taking. Pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.
You may take quick-acting narcotic pain medications for sudden (breakthrough) pain if so directed by your doctor. Also follow your doctor's or pharmacist's instructions for safely using non-narcotic pain relievers (e.g., naproxen, ibuprofen). If you have been using other long-acting narcotic pain medications or narcotic patches regularly, check with your doctor or pharmacist since they may need to be stopped before you start using this medication. If you are currently using a narcotic patch (e.g., fentanyl), the effects may continue after it is removed. Ask your doctor or pharmacist when it will be safe to start taking this medication (usually 18 hours after removing the patch).
This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as restlessness, sweating, shaking, body aches, stomach cramps, nausea) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions right away.
Though very unlikely, abnormal drug-seeking behavior (addiction) is possible with this medication. To lessen the risk of becoming addicted, 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.
