Five Codeine Side Effects
Understanding Codeine Side Effects
When taking codeine, understanding its potential side effects is crucial for managing and mitigating any adverse reactions. This section focuses on common side effects and how to manage them effectively.
Common Side Effects of Codeine
Codeine is known to cause a variety of side effects, some of which are more common than others. These side effects may occur as the body adjusts to the medication and typically do not require medical attention. Here are five common side effects associated with codeine use:
- Nausea and Vomiting: Often experienced when first taking codeine, these gastrointestinal issues usually subside after a few days.
- Constipation: A frequent side effect of opioid use, constipation can be managed with dietary adjustments or over-the-counter remedies.
- Drowsiness: Codeine can cause drowsiness, making it important to avoid activities that require alertness, such as driving.
- Dizziness: Feeling lightheaded or dizzy is another common side effect, especially when standing up quickly.
- Dry Mouth: Codeine may reduce saliva production, leading to a dry mouth sensation.
Management of Side Effects
Managing the side effects of codeine involves several strategies that can help alleviate discomfort and improve overall well-being. Here are some tips for managing the five common side effects:

Gastrointestinal Effects
Codeine, a commonly prescribed opioid, can cause a range of gastrointestinal side effects. Understanding and managing these effects are crucial for individuals and families impacted by substance use.
Nausea and Vomiting
Nausea and vomiting are frequent adverse effects of codeine administration. These symptoms often occur when an individual first begins taking the medication. According to NCBI Bookshelf, these effects usually diminish within days to weeks of continued exposure to the drug. Effective management strategies include the use of anti-emetic therapies, which are available in both oral and rectal formulations.
To alleviate nausea, individuals are advised to lie down for an hour after taking a dose or consult a healthcare provider for an over-the-counter or prescription nausea remedy.
Constipation
Constipation is one of the most common and persistent side effects associated with codeine use. Most patients experience constipation either upon initiating therapy or following dose increases. To mitigate this effect, increased fluid intake and the use of stool softeners are often recommended [3].
Effective management of constipation involves:
- Increasing fluid intake
- Using stool softeners
- Incorporating high-fiber foods into the diet

Understanding these gastrointestinal effects and their management can significantly improve the quality of life for those using codeine. By taking proactive measures, individuals can minimize discomfort and maintain better overall health.
Respiratory Complications
Codeine, an opioid analgesic, can cause significant respiratory complications. These issues range from breathing problems to serious respiratory depression.
Breathing Problems
Opioids like codeine can slow down the involuntary breathing rate controlled by the brain, which may result in low oxygen levels in the blood. In severe cases, both breathing rate and oxygen levels can drop dangerously low [2].
Symptoms of breathing problems can include:
- Shortness of breath
- Shallow or slow breathing
- Long pauses between breaths
These symptoms are especially concerning for children. Serious and life-threatening breathing problems, including slow or difficult breathing, have been reported in children who used codeine. As a result, it is generally not recommended for children under 18 years old for pain or cough treatment [4].
Adults with existing lung conditions or those who are elderly also face increased risks. For more details on the effects of opioids and their risks, please refer to our article on purple drank ingredients.
Respiratory Depression
Respiratory depression is one of the most serious adverse reactions associated with codeine. This condition involves a significant reduction in the ability to breathe automatically. This risk is particularly high during the first 24 to 72 hours of treatment and any time the dose is increased [4].
Signs of respiratory depression include:
- Slowed breathing
- Long pauses between breaths
- Shortness of breath
Certain populations are at higher risk, including older adults, those with lung diseases, head injuries, brain tumors, or conditions that increase brain pressure. Moreover, the FDA warns that individuals who are ultrarapid metabolizers (UMs) may experience life-threatening or fatal respiratory depression even at labeled dosage regimens. Respiratory depression and death have occurred in children who received codeine following tonsillectomy, adenoidectomy, or both, and had evidence of being CYP2D6 UMs [5].

Understanding these respiratory complications is crucial for anyone considering or currently using codeine. Always consult with a healthcare provider to discuss any potential risks and to find the safest treatment options available.
Cognitive and Hormonal Impact
Codeine, like other opioids, can have a range of effects on both cognitive function and hormonal balance. Understanding these impacts is crucial for individuals and families managing codeine use.
Cognitive Impairment
Cognitive issues may arise when starting to take opioids like codeine. These issues can include clouded mentation or sedation, leading some individuals to not feel like themselves. It is advised not to drive or operate heavy machinery while on opioids, as it may take a week or more to start feeling normal again.
Clouded mentation or sedation following codeine initiation tends to fade over time. Patients should be counseled about the drug's ability to affect their cognitive state, especially if they intend to drive or operate heavy machinery while on the medication until tolerance develops [3]. This is a critical consideration for those taking codeine for chronic pain management.
Hormonal Effects
Chronic use of codeine can lead to significant hormonal imbalances. One of the primary hormonal effects associated with the prolonged use of codeine is hypogonadism. This condition is characterized by reduced function of the gonads, leading to lower levels of sex hormones.
Abuse, misuse, and addiction can occur with codeine, and abrupt discontinuation in those who are physically dependent can lead to withdrawal reactions. Chronic use of controlled-released codeine is associated with hypogonadism and lower dehydroepiandrosterone sulfate (DHEA-S) levels. These hormonal changes can have wide-ranging effects on overall health and well-being.
Individuals who have more than two normal-function copies of the CYP2D6 gene ("ultrarapid metabolizers," UMs) can metabolize codeine to morphine more rapidly and completely. This can potentially lead to symptoms of morphine overdose, such as extreme sleepiness, confusion, and shallow breathing, which can be fatal [5]. Nursing mothers with ultrarapid CYP2D6 metabolism may produce breast milk containing higher levels of morphine, posing severe adverse events in their infants.
The FDA-drug label for codeine states that individuals who are ultrarapid metabolizers (UMs) may experience life-threatening or fatal respiratory depression or signs of overdose even at labeled dosage regimens. Respiratory depression and death have occurred in children who received codeine following tonsillectomy, adenoidectomy, or both, and had evidence of being CYP2D6 UMs.

Allergic Reactions and Precautions
Allergic Responses
Allergic reactions to opioids like codeine can occur in some individuals. These reactions can present with various symptoms, which include:
- Nausea
- Vomiting
- Itching
- Low blood pressure (hypotension)
- Constipation
If any of these symptoms arise, it's crucial to seek medical attention promptly [2].
Precautions and Interactions
When taking codeine, it's essential to be aware of certain precautions and potential drug interactions to avoid severe complications. Here are some key considerations:
Breathing Problems and Sedation
Taking codeine with certain medications can increase the risk of breathing problems, sedation, or even coma. Symptoms to watch for include:
- Unusual dizziness
- Lightheadedness
- Extreme sleepiness
- Slowed or difficult breathing
- Unresponsiveness
If any of these symptoms occur, seek emergency medical care immediately [4].
Alcohol and Street Drugs
Drinking alcohol or using street drugs during codeine treatment significantly increases the risk of serious, life-threatening side effects. It is strongly advised to avoid:
- Alcohol
- Medications containing alcohol
- Street drugs
These substances can exacerbate the side effects of codeine and lead to dangerous health consequences.
Ultrarapid Metabolizers (UMs)
Individuals with more than two normal-function copies of the CYP2D6 gene, known as "ultrarapid metabolizers" (UMs), can convert codeine to morphine more rapidly and completely. This can lead to symptoms of morphine overdose, such as:
- Extreme sleepiness
- Confusion
- Shallow breathing
In nursing mothers with ultrarapid CYP2D6 metabolism, this rapid conversion can result in higher levels of morphine in breast milk, posing severe adverse events to their infants.

By understanding these allergic responses and taking necessary precautions, individuals can navigate the use of codeine more safely and effectively.
Serious Risks and Considerations
Life-Threatening Reactions
Codeine carries significant risks that can be life-threatening, particularly concerning respiratory complications. Serious and life-threatening breathing problems, including slow or difficult breathing and even deaths, have been reported in children who used codeine. Due to this, codeine is generally not recommended for children under 18 years old for pain or cough treatment.
Breathing problems may occur especially within the first 24 to 72 hours of treatment and any time the dose is increased. Symptoms include slowed breathing, long pauses between breaths, or shortness of breath. This risk is notably higher in older adults and individuals with lung diseases, head injuries, brain tumors, or conditions that increase brain pressure.
Additionally, individuals who are ultrarapid metabolizers (UMs) of codeine may experience life-threatening or fatal respiratory depression even at labeled dosages. This has been observed in children who received codeine following tonsillectomy or adenoidectomy and had evidence of being CYP2D6 UMs.
Special Populations and Warnings
Certain populations are at an increased risk of experiencing severe side effects from codeine. The FDA recommends avoiding codeine usage in adolescents between 12 and 18 years old with specific risk factors such as conditions associated with hypoventilation, post-operative status, obstructive sleep apnea, obesity, severe pulmonary disease, neuromuscular disease, and concomitant use of other medications that cause respiratory depression.
Special warnings are also issued for individuals who have a history of substance abuse or mental health conditions, as they may be more susceptible to misuse and addiction. Those with a history of allergic reactions to codeine or other opioids should avoid use to prevent severe allergic responses.
