What is 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.

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.

Before taking this medicine

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 should I take codeine?

Take codeine exactly as prescribed by your doctor. Follow all directions on your prescription label. Codeine can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.

Codeine may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away codeine is against the law.

Take this medicine with food or milk if it upsets your stomach.

Drink 6 to 8 full glasses of water daily to help prevent constipation while you are taking this medicine. Do not use a stool softener (laxative) without first asking your doctor.

Do not stop using codeine suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.

Store at room temperature away from moisture and heat. Keep track of your medicine. Codeine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.

Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, mix the leftover medicine with cat litter or coffee grounds in a sealed plastic bag throw the bag in the trash.

What happens if I miss a dose?

Since this medicine is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line . A codeine overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose can cause severe muscle weakness, cold and clammy skin, pinpoint pupils, very slow breathing, extreme drowsiness, or coma.

What to avoid

Do not drink alcohol. Dangerous side effects or death could occur.

Codeine may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or severe drowsiness can cause falls or other accidents.

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.

Dosing information

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.

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.

Hydrocodone https://drugonomy.com/2025/10/14/hydrocodone/ https://drugonomy.com/2025/10/14/hydrocodone/#respond Tue, 14 Oct 2025 06:19:37 +0000 https://medicine-21.com/Drugs/?p=7902 Generic name: hydrocodone (oral) [ HYE-droe-KOE-done ]
Brand names: Hysingla ER, Zohydro ER
Drug classes: Antitussives  , Opioids (narcotic analgesics) 

What is hydrocodone?

Hydrocodone is an opioid pain medication.

Zohydro ER and Hysingla ER are extended-release forms of hydrocodone that are used for around-the-clock treatment of severe pain.

Extended-release hydrocodone is not for use on an as-needed basis for pain.

Warnings

Hydrocodone can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Do not crush, break, or open an extended-release pill. Swallow it whole to avoid exposure to a potentially fatal dose.

Hydrocodone may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.

Tell your doctor if you are pregnant. Hydrocodone may cause life-threatening withdrawal symptoms in a newborn if the mother has taken this medicine during pregnancy.

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

Before taking this medicine

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

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

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

  • breathing problems, sleep apnea;
  • a head injury, brain tumor, or seizures;
  • drug or alcohol addiction, or mental illness;
  • urination problems;
  • liver or kidney disease;
  • problems with your gallbladder, pancreas, or thyroid; or
  • a heart rhythm disorder called long QT syndrome.

If you use opioid 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 opioids may need medical treatment for several weeks.

Ask a doctor before using hydrocodone if you are breastfeeding. Tell your doctor if you notice severe drowsiness or slow breathing in the nursing baby.

How should I take hydrocodone?

Hydrocodone may be habit-forming, even at regular doses. Follow the directions on your prescription label and read all medication guides. Never use hydrocodone in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of this medicine.

Never share opioid medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it. Selling or giving away opioid medicine is against the law.

Your dose needs may be different if you have recently used a similar opioid pain medicine and your body is tolerant to it. Talk with your doctor if you are not sure you are opioid-tolerant.

Do not crush, break, or open an extended-release pill. Swallow it whole to avoid exposure to a potentially fatal dose. Never crush or break a hydrocodone pill to inhale the powder or mix it into a liquid to inject the drug into your vein. This can cause death.

Do not stop using this medicine suddenly after long-term use, or you could have serious withdrawal symptoms. Ask your doctor how to safely stop using hydrocodone.

Store at room temperature, away from heat, moisture, and light. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.

Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.

Dosing information

Usual Adult Dose for Chronic Pain:

The following dosing recommendations can only be considered suggested approaches to what is actually a series of clinical decisions over time; each patient should be managed individually.

As First Opioid Analgesic and For Patients who are NOT Opioid Tolerant:
Extended-Release Capsules (Zohydro(R) ER): Initial dose: 10 mg orally every 12 hours
Extended-Release Tablets (Hysingla(R) ER): Initial dose: 20 mg orally every 24 hours

Comments:
-Use of higher starting doses in patients who are not opioid tolerant may cause fatal respiratory depression; monitor patients closely for respiratory depression, especially during the first 24 to 72 hours.
-An opioid tolerant patient is one who has been receiving for 1-week or longer at least: oral morphine 60 mg/day, fentanyl transdermal patch 25 mcg per hour, oral oxycodone 30 mg/day, oral hydromorphone 8 mg/day, oral oxymorphone 25 mg/day, or an equianalgesic dose of another opioid.

What happens if I miss a dose?

Since hydrocodone is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next dose. Do not use two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line . A hydrocodone overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include severe drowsiness, pinpoint pupils, slow breathing, or no breathing.

Your doctor may recommend you get naloxone (a medicine to reverse an opioid overdose) and keep it with you at all times. A person caring for you can give the naloxone if you stop breathing or don’t wake up. Your caregiver must still get emergency medical help and may need to perform CPR (cardiopulmonary resuscitation) on you while waiting for help to arrive.

Anyone can buy naloxone from a pharmacy or local health department. Make sure any person caring for you knows where you keep naloxone and how to use it.

What to avoid

Do not drink alcohol. Dangerous side effects or death could occur.

Avoid driving or hazardous activity until you know how hydrocodone will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries.

Hydrocodone side effects

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

Opioid medicine can slow or stop your breathing, and death may occur. A person caring for you should give naloxone and/or seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

Stop using hydrocodone and 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;
  • pain or burning when you urinate;
  • confusion, tremors, severe drowsiness;
  • a light-headed feeling, like you might pass out;

  • high levels of serotonin in the body – agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, diarrhea.

Serious breathing problems may be more likely in older adults and in those who are debilitated or have wasting syndrome or chronic breathing disorders.

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.

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 hydrocodone side effects may include:

  • constipation, nausea, vomiting;
  • dizziness, drowsiness, feeling tired;
  • headache; or
  • cold symptoms such as stuffy nose, sneezing, sore throat.

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 .

What other drugs will affect hydrocodone?

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 opioids – 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.
