This medication is used to help relieve mild to moderate pain. Codeine belongs to a class of drugs known as opioid (narcotic) analgesics. It works in the brain to change how your body feels and responds to pain.
How to use Codeine Sulfate
Read the Medication Guide provided by your pharmacist before you start taking codeine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
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 the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. 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. For children, the dosage is also based on weight. Do not increase your dose or use this drug more often or for longer than prescribed, because your risk of side effects may increase. 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 opioid medications. In that case, this medication might be used for sudden (breakthrough) pain only as needed. Other pain relievers (such as acetaminophen, ibuprofen) may also be prescribed. Ask your doctor or pharmacist about using codeine safely with other drugs.
Suddenly stopping this medication may cause withdrawal, especially if you have used it for a long time or in high doses. To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as restlessness, mental/mood changes (including anxiety, trouble sleeping, thoughts of suicide), watering eyes, runny nose, nausea, diarrhea, sweating, muscle aches, or sudden changes in behavior.
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.
