Take this medication by mouth as directed by your doctor. You may take this drug with or without food. If you have nausea, it may help to take this drug with food. Ask your doctor or pharmacist about other ways to decrease nausea (such as lying down for 1 to 2 hours with as little head movement as possible).
If you are using a liquid form of this medication, use a medication measuring device to carefully measure the prescribed dose. Do not use a household spoon because you may not get the correct dose.
The dosage is based on your medical condition and response to treatment. Do not increase your dose, take the medication more frequently, or take it for a longer time than prescribed. Properly stop the medication when so directed.
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.
If you have ongoing pain (such as due to cancer), your doctor may direct you to also take long-acting narcotic medications. In that case, this medication might be used for sudden (breakthrough) pain only as needed. Other non-narcotic pain relievers (such as naproxen, ibuprofen) may also be prescribed with this medication. Ask your doctor or pharmacist if you have any questions about using this product safely with other drugs.
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, watering eyes, runny nose, nausea, sweating, muscle aches) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Ask your doctor or pharmacist for more details, and report any withdrawal reactions immediately.
When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.
Along with its benefits, this medication may rarely cause abnormal drug-seeking behavior (addiction). This risk may be increased if you have abused alcohol or drugs in the past. Take this medication exactly as prescribed to lessen the risk of addiction.
Tell your doctor if your pain persists or worsens.
