Codeine

Generic name: Codeine

Usage of Codeine

Codeine is an opioid pain reliever which is used to treat mild to moderately severe pain and to help reduce coughing. Codeine is available as a single ingredient tablet and also available in multi ingredients products combined with other pain relieving medicines or cold and flu medicines.

Codeine side effects

Get emergency medical help if you have signs of an allergic reaction to codeine: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Like other narcotic medicines, codeine can slow your breathing. Death may occur if breathing becomes too weak.

A person caring for you should seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

Call your doctor at once if you have:

  • noisy breathing, sighing, shallow breathing, breathing that stops during sleep;
  • a slow heart rate or weak pulse;
  • a light-headed feeling, like you might pass out;
  • confusion, agitation, hallucinations, unusual thoughts or behavior;
  • feelings of extreme happiness or sadness;
  • seizure (convulsions);
  • problems with urination; or
  • low cortisol levels--nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.

    • Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

    Serious side effects may be more likely in older adults and those who are overweight, malnourished, or debilitated.

    Long-term use of opioid medication may affect fertility (ability to have children) in men or women. It is not known whether opioid effects on fertility are permanent.

    Common codeine side effects include:

  • feeling dizzy or drowsy;
  • nausea, vomiting, stomach pain;
  • constipation;
  • sweating; or
  • mild itching or rash.

    • This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

    Before taking Codeine

    You should not use this medicine if you are allergic to it, or if you have:

  • severe asthma or breathing problems;
  • a blockage in your stomach or intestines; or
  • frequent asthma attacks or hyperventilation.

    • In some people, codeine breaks down rapidly in the liver and reaches higher than normal levels in the body. This can cause dangerously slow breathing and may cause death, especially in a child.

    Do not give codeine to anyone younger than 18 years old.

    To make sure this medicine is safe for you, tell your doctor if you have ever had:

  • liver disease;
  • breathing problems, sleep apnea;
  • asthma, COPD, sleep apnea, or other breathing disorders;
  • abnormal curvature of the spine that affects breathing;
  • kidney disease;
  • a head injury or brain tumor;
  • low blood pressure;
  • blockage in your digestive tract (stomach or intestines);
  • a gallbladder or pancreas disorder;
  • underactive thyroid;
  • Addison's disease or other adrenal gland disorder;
  • enlarged prostate, urination problems; or
  • mental illness, drug or alcohol addiction.

    • Some medicines can interact with codeine and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take stimulant medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. Ask your doctor before making any changes in how or when you take your medications.

    If you use this medicine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.

    Do not breast-feed while taking codeine. This medicine can pass into breast milk and cause drowsiness, breathing problems, or death in a nursing baby.

    How to use Codeine

    Usual Adult Dose for Pain:

    Initial dose: 15 to 60 mg orally up to every 4 hours as needed Maximum dose: 360 mg in 24 hours Comments: -Initial doses should be individualized taking into account severity of pain, response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse. -Doses higher than 60 mg have not been shown to improve pain relief and are associated with an increased incidence of adverse effects. -Because of the risks of addiction, abuse and misuse, the lowest effective dose for the shortest duration consistent with individual patient treatment goals should be used. -Monitor patients closely for respiratory depression within the first 24 to 72 hours of initiating therapy and following any increase in dose. Use: For the management of mild to moderate pain where treatment with an opioid is appropriate and from which alternative treatments are inadequate.

    Warnings

    You should not use codeine if you have severe breathing problems, a blockage in your stomach or intestines, or frequent asthma attacks or hyperventilation.

    Codeine can slow or stop your breathing, cause profound sedation, and may be habit-forming. MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.

    Codeine is not for use in anyone under 18 years old.

    Taking codeine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.

    Fatal side effects can occur if you use codeine with alcohol, or with other drugs that cause drowsiness, sedation or slow your breathing.

    What other drugs will affect Codeine

    You may have breathing problems or withdrawal symptoms if you start or stop taking certain other medicines. Tell your doctor if you also use an antibiotic, antifungal medication, heart or blood pressure medication, seizure medication, or medicine to treat HIV or hepatitis C.

    Opioid medication can interact with many other drugs and cause dangerous side effects or death. Be sure your doctor knows if you also use:

  • cold or allergy medicines, bronchodilator asthma/COPD medication, or a diuretic ("water pill");
  • medicines for motion sickness, irritable bowel syndrome, or overactive bladder;
  • other narcotic medications - opioid pain medicine or prescription cough medicine;
  • a sedative like Valium - diazepam, alprazolam, lorazepam, Xanax, Klonopin, Versed, and others;
  • drugs that make you sleepy or slow your breathing - a sleeping pill, muscle relaxer, medicine to treat mood disorders or mental illness; or
  • drugs that affect serotonin levels in your body- a stimulant, or medicine for depression, Parkinson's disease, migraine headaches, serious infections, or nausea and vomiting.

    Popular FAQ

    Codeine acts on your brain and nervous system to lessen the way you feel pain. Codeine works by weakly binding to a specific opioid receptor, known as the mu-opioid receptor, but with much less affinity than morphine, which means its pain-relieving effects are not as strong as morphine's.

    Codeine is an oral prescription opioid (narcotic) drug most commonly used to treat mild-to-moderate pain, as a cough suppressant, and to help relieve pain from tension headaches. It is often combined with other medications for these or other uses and can be habit-forming.

    You should take codeine tablets at least FOUR hours apart. Do not take them any more frequently than every four hours.
