What It's For & How To Take
Codeine is used to relieve mild to moderate pain. It is also used, usually in combination with other medications, to reduce coughing. This medication is an opiate, and it works in the brain to block how the body recognizes pain. When codeine is used to reduce coughing, it works by decreasing the activity in the part of the brain that causes coughing.
Codeine is usually prescribed to be taken at the lowest effective dose for the shortest effective treatment cycle. Your dose is based on your condition and response to treatment. This medication may be taken with or without food.
Codeine is also available as an ingredient in many cough and pain medications. This session only includes information about the use of codeine. If you are taking a codeine combination product, be sure to read information about all the ingredients in the product you are taking and ask your doctor or pharmacist for more information.
This medication works best when taken at the first sign of pain. If you wait until the pain has worsened, the medication may not work as well or may take much longer for you to notice the expected pain relief.
If you have an ongoing pain syndrome, such as cancer or chronic back pain, you may be taking codeine along with a long-acting pain medication. This medication will be used for sudden or sharp pain that flares up during certain times of the day.
Tell your doctor if your pain is not getting better. Your dose is based on your current condition and may need to be changed as your condition changes. If you have been taking this medication for an extended period of time, do not suddenly stop taking it because you may feel uncomfortable withdrawal symptoms such as muscle aches, sweating, nausea, and vomiting. Your doctor may decrease your dose over a time to decrease the withdrawal symptoms.
