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.

Carbamazepine is an anticonvulsant. It works by decreasing nerve impulses that cause seizures and nerve pain, such as trigeminal neuralgia and diabetic neuropathy.

Carbamazepine is also used to treat bipolar disorder.

Carbamazepine may also be used for purposes not listed in this medication guide.

Warnings

You should not take carbamazepine if you have a history of bone marrow suppression, if you are allergic to it, or take an antidepressant such as amitriptyline, desipramine, doxepin, imipramine, or nortriptyline.

TELL YOUR DOCTOR ABOUT ALL OTHER MEDICINES YOU USE. Some drugs can raise or lower your blood levels of carbamazepine, which may cause side effects or make this medicine less effective. Carbamazepine can also affect blood levels of certain other drugs, making them less effective or increasing side effects.

Carbamazepine may cause serious blood problems or a life-threatening skin rash or allergic reaction. Call your doctor if you have a fever, unusual weakness, bleeding, bruising, or a skin rash that causes blistering and peeling.

Some people have thoughts about suicide while taking seizure medicine. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Do not stop taking this medicine without asking your doctor first, even if you feel fine.

If you are pregnant, do not start or stop taking carbamazepine without your doctor’s advice.

Before taking this medicine

You should not take carbamazepine if you have a history of bone marrow suppression, or if you are allergic to carbamazepine or to an antidepressant such as amitriptyline, desipramine, doxepin, imipramine, or nortriptyline.

Common carbamazepine side effects may include:

• dizziness, loss of coordination, problems with walking;
• nausea, vomiting; or
• drowsiness.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.

What other drugs will affect carbamazepine?

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.

Using carbamazepine with other drugs that make you drowsy can worsen this effect. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety, depression, or seizures.

Many drugs can interact with carbamazepine, and some drugs should not be used together. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide. Tell your doctor about all your current medicines and any medicine you start or stop using.

Buprenorphine is an opioid medication used to treat opioid use disorder (OUD), acute pain, and chronic pain. 

Buprenorphine is used for opioid addiction to reduce cravings and withdrawal symptoms without causing euphoria or dangerous side effects and helps prevent relapse. It works by being a substitute for the drug being abused, so the patient has minimal discomfort, which allows the patient to focus on their recovery. Buprenorphine for OUD is used as part of a complete treatment program that also includes counseling and behavioral therapy.

For opioid use disorder, buprenorphine is available as long-acting injections (Sublocade, Brixadi) and sublingual tablets (Subutex discontinued, generics available). 

Buprenorphine is used to treat acute pain that is severe enough to require an opioid analgesic and moderate to severe chronic pain that is not controlled by other medicines. For chronic around-the-clock pain, it is available as buprenorphine skin patches (Butrans) and buprenorphine buccal films (Belbuca), and for acute pain is available as an injection (Buprenex).

Buprenorphine-naloxone combinations are also available to be used for opioid addication and include sublingual film (Bunavail), sublingual film and sublingual tablets (Suboxone), and sublingual tablets (Zubsolv).

Buprenorphine’s mechanism of action is that is a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor.

Is buprenorphine a controlled substance?

Yes, buprenorphine is a Schedule III controlled drug, which means it has a potential for abuse more than those in Schedules 4 and 5. If abused, it may lead to moderate or low physical dependence or high psychological dependence.

Warnings

MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep buprenorphine in a place where others cannot get to it.
Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose. Patients should have access to naloxone to treat opioid overdose based on the patient’s risk factors for overdose, such as currently using a CNS depressant, a history of an opioid use disorder, or previous opioid overdose.  Having naloxone available is important if the patient has household members (including children) or other close contacts at risk for accidental exposure or overdose.

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

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

Before taking this medicine

You should not use this medicine if you are allergic to buprenorphine or:

• If you have used another narcotic drug within the past 4 hours.

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

• methadone treatment;
• breathing problems, sleep apnea;
• abnormal curvature of the spine that affects breathing;
• liver disease (especially hepatitis B or C);
• kidney disease;
• enlarged prostate, urination problems;
• a head injury or brain tumor;
• alcoholism, hallucinations, mental illness; or
• problems with your stomach, gallbladder, adrenal gland, or thyroid.

Pregnancy

If you use buprenorphine 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.

Infertility

Chronic use of opioids may cause reduced fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible 

Breastfeeding

Buprenorphine can pass into breast milk and may cause drowsiness and breathing problems in a nursing baby. Ask your doctor about any risk to your baby.

How should I take buprenorphine?

Use buprenorphine exactly as it was prescribed for you. Follow the directions on your prescription label and read all medication guides. Your doctor may occasionally change your dose. Never use this medication in larger amounts, or for longer than prescribed.

Opioid Use Disorder

Buprenorphine Sublingual (for OUD)

Buprenorphine sublingual is usually taken only at the start of treatment for addiction (induction phase). Most people are later switched to long-acting buprenorphine (Sublocade injection or Brixadi injection) or another medicine that contains buprenorphine with naloxone (Bunavail, Suboxone, Zubsolv). You may receive your first doses of buprenorphine sublingual in a hospital or clinic setting until your condition improves. Use dry hands when handling the tablet. Place the tablet under your tongue and allow it to dissolve with your mouth closed. Do not chew the tablet or swallow it whole. If your doctor has prescribed more than 2 tablets per dose, place the correct number of tablets under your tongue at the same time and allow them to dissolve completely. Do not eat or drink anything until the tablet has completely dissolved in your mouth. Never crush or break a pill to inhale the powder or mix it into a liquid to inject the drug into your vein. Doing so could result in death.

Extended-release buprenorphine subcutaneous injection (for OUD)

Buprenorphine extended-release injection is given subcutaneously (just under the skin). Sublocade and Brixadi can be given in the abdomen, thigh, buttock, or the back of the upper arm. 

Sublocade should only be used when patients have received treatment with at least one dose (eg, 4 mg) of an oral transmucosal (used under the tongue or inside the cheek) buprenorphine-containing medicine. Sublocade is injected as a liquid. After the injection, Sublocade changes to a solid form called a depot. The depot may be seen or felt as a small bump under your skin at the injection site on your abdomen, thigh, buttock, or back of the upper arm, for several weeks. The depot will get smaller over time. Do not try to remove the depot, and do not rub or massage the injection site. Sublocade is part of a complete treatment plan that should include counseling.

Brixadi should only be used if you are currently receiving buprenorphine treatment or if your healthcare provider has given you a test dose of buprenorphine first to see if you are able to tolerate it. If you are new to Brixadi treatment, the upper arm should only be used after 4 doses of Brixadi in your buttock, thigh, or stomach. Brixadi is injected as a liquid; after the injection, the liquid changes to a gel form called a depot. The depot is not always felt under the skin. Do not try to remove the depot. Brixadi is part of a complete treatment plan that should include counseling.

Pain

Buprenex (buprenorphine injection) is used for pain, it is given by deep intramuscular or slow (over at least 2 minutes) intravenous injection at up to 6-hour intervals, as needed.

Butrans skin patch is used for chronic around-the-clock pain. It is applied once a week and worn continuously for 1 week. Do not change your dose. Apply Butrans exactly as prescribed by your healthcare provider. Your doctor will prescribe you the lowest effective dose for the shortest time needed. Do not take hot baths or sunbathe, use hot tubs, saunas, heating pads, electric blankets, heated waterbeds, or tanning lamps as these can cause an overdose that can lead to death.

Belbuca buccal films are used for around-the-clock treatment of moderate to severe chronic pain. Using a finger, place the yellow side of the Belbuca buccal film against the inside of your moistened cheek. Press and hold the Belbuca buccal film in place for 5 seconds and then take your finger away. Once in place, the film will dissolve completely in about 30 minutes. Do not eat or drink anything until the Belbuca film has completely dissolved in your mouth. Rinse your mouth with water after the medicine dissolves. Wait one hour after the film dissolves to brush your teeth to prevent damage to the teeth and gums. Do not chew the Belbuca film or swallow it whole. You should receive regular dental checkups while using Belbuca.
