WARNING
The risks of taking acetaminophen and codeine include:
- Respiratory Depression: Codeine can slow down breathing, which can be dangerous, especially in high doses or when combined with other depressants like alcohol.
- Liver Damage: Excessive use of acetaminophen can lead to severe liver damage or failure.
- Constipation: Codeine often causes constipation, which can be uncomfortable and require management.
- Dependence and Withdrawal: Long-term use of codeine can lead to physical dependence and withdrawal symptoms if the medication is stopped suddenly.
- Allergic Reactions: Severe allergic reactions, including rash, swelling, or difficulty breathing, can occur.
- Drowsiness and Dizziness: Both acetaminophen and codeine can cause drowsiness, dizziness, or impaired coordination, increasing the risk of accidents.
- Overdose Risk: Taking too much of the medication can lead to overdose, with symptoms including extreme drowsiness, slow breathing, or loss of consciousness.
Always use this medication as prescribed and be aware of these risks.
Why is this medication prescribed?
Acetaminophen and Codeine is a combination medication used to relieve moderate to severe pain. Acetaminophen (Tylenol) is a non-opioid pain reliever and fever reducer. It works by inhibiting the production of certain chemicals in the brain that cause pain and fever. Codeine is an opioid (narcotic) pain reliever. It works by altering the way the brain and nervous system respond to pain. This combination is typically prescribed when other pain relievers, like non-opioid medications (e.g., ibuprofen or acetaminophen alone), are not sufficient. In some cases, codeine is also used to suppress cough, although this use has become less common due to concerns about side effects.
How should this medicine be used?
Here’s a general overview of how it’s used:
- Dosage: Follow your doctor’s instructions carefully. The dosage depends on the severity of your pain and your medical history. It’s usually taken every 4 to 6 hours as needed for pain, but not more frequently than prescribed.
- Administration: Take the medication by mouth with or without food. If you experience nausea, taking it with food might help.
- Do Not Exceed Dosage: Be careful not to exceed the prescribed dose, particularly with acetaminophen, as taking too much can lead to liver damage.
- Avoid Alcohol: Do not consume alcohol while taking this medication, as it increases the risk of liver damage from acetaminophen and can enhance the sedative effects of codeine.
- Risk of Addiction: Codeine is habit-forming, so use it exactly as prescribed. Do not take larger doses, take it more often, or use it for a longer time than prescribed.
- Missed Dose: If you miss a dose and are using the medication on a regular schedule, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose. Do not double up to make up for a missed dose.
- Storage: Store the medication at room temperature, away from moisture and heat. Keep it out of reach of children and pets.
- Disposal: Dispose of unused or expired medication properly, following the guidelines provided by your pharmacist or local waste disposal company. Do not flush the medication down the toilet or pour it into a drain unless instructed.
Always follow your doctor’s instructions and consult them if you have any questions or experience any side effects.
Other uses for this medicine
- Cough Relief: Codeine, as an opioid, has cough suppressant properties and may sometimes be used to treat severe cough, though this is less common due to the risk of dependence and side effects.
- Post-Surgical Pain: It is commonly prescribed after surgery to manage pain when non-opioid pain relievers are insufficient.
What special precautions should I follow?
When using acetaminophen and codeine, certain precautions are necessary to minimize risks:
- Allergies: Inform your doctor if you have any allergies to acetaminophen, codeine, or other opioids, or if you have had allergic reactions to other medications.
- Medical History: Disclose any history of liver disease, kidney disease, breathing problems (e.g., asthma, sleep apnea), head injuries, brain disorders, or mental/mood disorders (e.g., depression, anxiety).
- Pregnancy and Breastfeeding: This medication should be used with caution during pregnancy and breastfeeding, as codeine can pass into breast milk and may harm a nursing infant.
- Interactions with Other Medications: Provide a full list of medications, supplements, and herbal products you are taking to your doctor, as acetaminophen and codeine can interact with other drugs, particularly other pain relievers, sedatives, antidepressants, and alcohol.
- Avoid Alcohol: Do not drink alcohol while taking this medication, as it can increase the risk of liver damage and enhance the sedative effects of codeine, leading to dangerous side effects.
- Operating Machinery: Since codeine can cause drowsiness and dizziness, avoid driving or operating heavy machinery until you know how the medication affects you.
- Signs of Overdose: Be aware of symptoms of overdose, such as extreme drowsiness, slow or difficult breathing, or loss of consciousness, and seek emergency medical help if they occur.
- Watch for Liver Damage: Acetaminophen in high doses can cause liver damage. Make sure you’re not taking other medications that contain acetaminophen to avoid exceeding the daily limit.
- Dependence and Tolerance: Long-term use can lead to tolerance, meaning higher doses are needed to achieve the same effect, and dependence, which means withdrawal symptoms may occur if you stop taking the medication. Use the lowest effective dose for the shortest duration possible.
Always follow your healthcare provider’s instructions and report any unusual or severe side effects immediately.
What special dietary instructions should I follow?
- General Diet: There are no specific dietary restrictions while taking acetaminophen and codeine. However, it’s important to stay hydrated and eat a balanced diet.
- Avoid Alcohol: Do not consume alcohol, as it can increase the risk of serious side effects, such as liver damage and respiratory depression.
What should I do if I forget a dose?
- Take the Missed Dose: If you remember shortly after the scheduled time, take the missed dose as soon as you remember.
- Skip if Close to Next Dose: If it’s almost time for your next dose, skip the missed dose. Do not double up to make up for the missed dose, as this could increase the risk of side effects.
- Resume Regular Schedule: Continue with your regular dosing schedule after the missed dose.
