Codeine is an opioid medication that is commonly used to relieve mild to moderate pain and suppress coughing. While it is effective in treating these conditions, codeine also has several side effects and can be habit-forming, leading to physical dependence and substance use disorder. Taking codeine with certain medications or substances, such as alcohol, can increase the risk of serious side effects, including life-threatening breathing problems, sedation, coma, and even death. In addition, codeine may cause muscle spasms, twitching, and cramps, which can be a symptom of serotonin syndrome or withdrawal from the medication. It is important to consult a doctor before taking codeine and to be aware of the potential risks and side effects associated with its use.

What You'll Learn

Codeine is an opioid
Codeine is a member of the opioid class of medications. It is a natural opioid derived from the opium poppy. It is the most commonly used opioid medication in Canada and is available as an over-the-counter medication in several countries, including Denmark, Japan, Poland, and the United Kingdom. In the USA and Australia, it is a prescription medication.
Codeine is used to manage mild to moderate pain and to treat coughs. It is often used in combination with other medications, such as acetaminophen or an NSAID like ibuprofen, to relieve symptoms of the common cold or flu in adults. It is also available in syrup form, especially for children, and is sometimes mixed with soft drinks.
As an opioid, codeine can cause physical dependence and substance use disorder within weeks of regular use. It is important to gradually reduce the dose over time before stopping completely to avoid withdrawal symptoms. Codeine may also cause serious or life-threatening breathing problems, especially during the first 24 to 72 hours of treatment and when the dose is increased. It is important to store codeine securely and out of the reach of children, as it can cause serious and even fatal side effects in individuals who are not prescribed the medication.
The use of codeine carries a high risk of misuse, abuse, addiction, and increased mortality, as seen in the opioid epidemic. It is crucial to screen patients for risk factors of opioid misuse before initiating codeine therapy and to monitor their response closely. While codeine is effective in treating pain, its benefits must be weighed against the potential risks associated with its use.

Side effects of codeine
Codeine is an opioid medication that is commonly used to relieve coughs and mild to moderate pain. It is available in prescription and non-prescription medications, often in combination with other medicinal ingredients such as acetaminophen or acetylsalicylic acid.
While codeine can be an effective pain reliever, it is important to be aware of its potential side effects. One of the most significant risks associated with codeine is physical dependence. Codeine can cause physical dependence and substance use disorder within weeks of regular use, and long-term use can lead to worsening pain, known as "opioid-induced hyperalgesia". Additionally, codeine has been linked to respiratory issues, including slowed breathing and, in some cases, life-threatening breathing problems. It is important to seek immediate medical attention if you or someone you know is experiencing breathing difficulties related to codeine use.
Another side effect of codeine is its impact on the adrenal glands. Prolonged codeine use can lead to adrenal insufficiency, where the adrenal glands produce less cortisol, the stress hormone. This condition can worsen if the body is under stress due to fever, surgery, or trauma. Codeine may also cause low blood pressure, which can lead to dizziness or fainting.
Codeine has also been known to cause gastrointestinal issues, such as constipation and, in combination with acetaminophen and acetylsalicylic acid, can result in liver toxicity and gastrointestinal bleeding. It is important to be cautious of drug interactions when taking codeine, as it may have harmful interactions with other medications, especially those that affect the central nervous system (CNS). Mixing codeine with alcohol or CNS depressants, such as antihistamines or sedatives, can enhance its side effects, including dizziness, poor concentration, drowsiness, unusual dreams, and trouble sleeping.
Furthermore, codeine may cause muscle twitching, spasms, and cramps. It can also lead to more severe muscle issues, such as severe muscle stiffness, loss of coordination, and muscle aches. In some cases, codeine may also cause seizures, especially in individuals with a seizure disorder.
It is important to consult a doctor or healthcare provider if you experience any adverse side effects while taking codeine. They can advise you on the appropriate course of action and help manage any potential risks associated with codeine use.

Codeine and alcohol
Codeine is an opioid analgesic drug and a derivative of the opium poppy. It is a widely used prescription opioid for pain management and cough suppression. It is also available over the counter in lower strengths for minor pain and coughs.
Alcohol and codeine are both central nervous system depressants. When consumed together, they can have a potentiating effect on each other, slowing vital functions like respiration, heartbeat, and cognitive processes. This can lead to dangerous side effects and increase the risk of overdose, which can be fatal. Mixing alcohol and codeine can also cause changes in thought processes and behaviour, impacting an individual's mental health.
The combination of alcohol and codeine can lead to a variety of health risks, including serious or life-threatening breathing problems, especially during the initial 24 to 72 hours of treatment or when the codeine dosage is increased. Other side effects may include unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness.
It is important to note that codeine can cause physical dependence and substance use disorder within weeks of regular use. Long-term use of codeine can lead to worsening pain, known as "opioid-induced hyperalgesia," and can result in liver toxicity and gastrointestinal bleeding when combined with certain medications.
Therefore, it is strongly advised to avoid consuming alcohol while taking codeine. If you are taking codeine, it is best to refrain from alcohol until the codeine has left your system. It is crucial to consult a doctor or pharmacist about any concerns or questions regarding the use of codeine and alcohol.

Withdrawal symptoms
Medications are available to help manage withdrawal symptoms and reduce cravings. For instance, non-narcotic medications such as acetaminophen (Tylenol) and ibuprofen (Motrin, Advil) can help reduce mild pain. In more severe cases, doctors may prescribe stronger medications such as clonidine (Catapres, Kapvay) to reduce anxiety and treat high blood pressure. Buprenorphine, a weak opioid, can also be used to ease withdrawal symptoms and reduce the risk of misuse and side effects from codeine.
It is important to seek professional treatment for codeine withdrawal to ensure a safe recovery process. Medically supervised detoxification and long-term treatment strategies, such as cognitive-behavioral therapy and support groups, can help individuals manage codeine withdrawal and prevent addiction.

Codeine and constipation
Opioid painkillers, including codeine, can have distressing side effects on the gut, such as constipation and other digestive symptoms. Codeine is an opioid that occurs naturally in the opium poppy. It is commonly used to relieve coughs and mild to moderate pain.
Codeine can cause constipation, and patients may also develop other gastrointestinal side effects, such as nausea, vomiting, bloating, abdominal pain, and straining. This is known as opioid-induced constipation (OIC) and accounts for 40-60% of patients without cancer who are receiving opioids. OIC may present immediately when a patient first takes an opioid or develop gradually during opioid therapy.
Laxatives must be started simultaneously with the opioid to prevent OIC. Treatment for OIC involves both pharmacological and non-pharmacological therapies. Stool softeners are ideal for preventing constipation but do not work well for established cases. Another laxative option is a saline laxative, such as magnesium citrate, which takes 30 to 180 minutes to work. For refractory cases of OIC, newer agents may be used, with methylnaltrexone being the most superior.
It is important to note that codeine may cause physical dependence and substance use disorder within weeks of regular use. It can also cause serious side effects, especially if taken by adults or children who are not used to strong narcotic pain medicines. Therefore, it should be stored securely and safely to prevent misuse.
