How to use codeine sulfate Oral
Take this medication by mouth as directed by your doctor. Pain medications work best when taken at the first signs of pain. If you wait until the pain has worsened, the medication may not work as well. The dosage is based on your medical condition and response to therapy. For children, the dosage is also based on weight.
If you are using the liquid form, 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. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. If you are extremely drowsy after using this medication, consult your doctor or pharmacist promptly. Your dosage may need to be lowered.
If so directed by your doctor, you may also use long-acting narcotic medications for ongoing pain. In that case, this medication might be used when needed for sudden attacks of \"breakthrough\" pain. Also follow your doctor\'s or pharmacist\'s instructions for the safe use of non-narcotic pain relievers (e.g., acetaminophen, ibuprofen). Ask your doctor or pharmacist if you have any questions about your treatment.
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, runny nose, watering eyes, trouble sleeping, severe abdominal/muscle pain, nausea, vomiting, rapid breathing, and fast heartbeat) 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 immediately.
Though it is very unlikely to occur, this medication can also be habit-forming and may result in abnormal drug-seeking behavior (addiction). Do not increase your dose, take it more frequently, or use it for a longer period of time than prescribed. Properly stop the medication when so directed. This will lessen the chances of becoming addicted.
When used for a long time, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well.
Inform your doctor if your pain persists or worsens.

Nausea commonly occurs with the use of codeine and usually goes away after the first few doses. Consult your doctor or pharmacist about ways to decrease nausea (e.g., antihistamines, taking with food, lying down for 1-2 hours with as little head movement as possible).
Lightheadedness, dizziness, drowsiness, dry mouth, flushing, vomiting, constipation, and sweating may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
To prevent constipation, maintain a diet adequate in fiber, drink plenty of water, and exercise. If you become constipated while using this drug, consult your pharmacist for help in selecting a laxative (such as stimulant-type with stool softener).
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
