Codeine Overdose Summary

  • Codeine is an opiate pain medication often used to treat injuries and chronic pain by blocking pain signals 
  • Like other opiates it is addictive and abusing it can lead to overdose and even death 
  • Codeine-related deaths have increased by almost 25% in 2021
  • Signs of a codeine overdose include: blue lips, clammy skin, small pupils, drowsiness, and unconsciousness
  • Overdosing on codeine damages your respiratory system which limits the oxygen getting to your brain, which can result in brain damage and death 
  • Long-term health effects of abusing codeine include liver and kidney damage, depression, and seizures
  • If you are experiencing or witnessing a codeine overdose you should call 999 (as it is a medical emergency)
  • If you are with someone experiencing a codeine overdose, keep them calm, clear the space in case they have a seizure, and put them in the recovery position if they become unconscious 
  • If they stop breathing, perform CPR 
  • Codeine overdose treatment may include IV fluids, laxatives, and breathing support, along with Naloxone to reverse opioid overdose
  • Codeine is commonly mixed with alcohol, benzodiazepines, and other opioids, despite the increased risk of side effects 
  • Codeine overdose is often a sign of underlying codeine addiction and once you have detoxed from codeine you should seek addiction treatment

Signs, Risks & Symptoms of a Codeine Overdose 

One of the most commonly used opioid narcotics in the world, codeine is a prescription drug used to treat mild to moderately severe pain. You may be prescribed codeine following an injury or for chronic pain which you cannot manage with other medication. 

It is available in tablet form, though can be used in cough syrup to treat coughs. Codeine is a fairly short-acting analgesic, with most effects wearing off after a few hours. Like all opiates, codeine can be addictive. 

For the duration of the time you take codeine, it is important you stick to the dosage prescribed by your healthcare provider. If you increase your dosage, it can cause you to overdose which can lead to severe complications. 

Unfortunately, many people increase the dosage because, along with the pain relief, they enjoy the feelings of joy and even euphoria that come with taking codeine. As your tolerance to codeine increases, you’ll need more and more to get those same pleasurable feelings. 

This happens because of the way opiates interact with the central nervous system, which involves activating the reward systems and releasing pleasurable hormones. But increasing the dose to chase these momentary feelings of euphoria can come with many serious health consequences and can lead to a codeine overdose. 

What Happens in a Codeine Overdose?

If you, or someone you know, is experiencing a codeine overdose you may notice the following signs: 

  • Blue lips or fingernails
  • Intense muscle weakness
  • Cold or clammy skin
  • Breathlessness 
  • Lethargy and fatigue
  • Small pupils
  • Slow pulse
  • Low blood pressure
  • Itching
  • Stomach pain 
  • Slurring 
  • Nausea
  • Drowsiness
  • Unconsciousness
  • Coma

Overdosing on codeine can also be fatal. This is more common when people have mixed codeine with other opiates, drugs, or alcohol. 

This happens because overdosing causes damage to your respiratory system, which reduces the amount of oxygen getting to your brain. This can result in your brain cells dying which can cause a coma, brain damage, and in some cases even death.

  • Kidney damage
  • Heightened sensitivity to pain
  • Acute pancreatitis
  • Depression

  • Coma
  • Seizure
  • Death

If You Think You’re Having (Or Witnessing) a Codeine Overdose 

It can be frightening to both witness or experience a codeine overdose, but the most important thing to remember is to stay as calm as possible. 

A codeine overdose is a medical emergency. So if you are worried you or someone you know has had a codeine overdose, call 999 immediately.

Before you call, try and make sure you know:

  • The person’s age
  • What combination of substances or alcohol they have taken with the codeine 
  • What time they took it at
  • How much they took 
  • If they had a prescription for the codeine 

If you aren’t sure of all of those details, don’t panic, just call for help. 

While you are waiting for help to arrive, it’s important to stay with the person you think has overdosed. 

If they remain conscious and start to become worried, the main thing to do is try to keep them as calm as possible by reassuring them that help is on its way and the chances are they will make a full recovery. 

If at any point they experience a seizure, you should clear the space they are in to minimise the chance of them hurting themselves. 

Should they become unconscious, put them in the recovery position and pay attention to their breathing. If at any point they stop breathing, you’ll need to perform CPR on them. You should contact 999 for guidance. 

How Are Codeine Overdoses Typically Treated? 

Once medical help has arrived, they will check the person’s vital signs including their blood pressure, breathing rate, pulse, and temperature. 

If you require hospital treatment, medical staff will most likely carry out a range of tests to find out exactly what is going on. These might include:

  • Blood test
  • Urine test
  • CT scan
  • X-ray of chest 
  • ECG

Depending on what those tests reveal, the treatment administered could include: 

  • IV fluids 
  • Laxative 
  • Breathing support 

Treatment could also include Naloxone, given under the brand names Prenoxad and Nyxoid. This medication is most commonly used to reverse opioid overdose.

If a reversal medication is not given, activated charcoal may be given as it can help limit the absorption and help eliminate certain drugs via the gastrointestinal tract. 

Once the person is stable, treatment for the underlying addiction will need to be considered. Various treatments are available for long-term addiction help, but to start with a codeine detox would be necessary. 

The withdrawal process can be uncomfortable, so going through the process in a professional, clinical setting at an addiction treatment centre is often the optimum way to do it. 

Mixing Codeine With Other Drugs 

You should read the information that comes with your codeine prescription before taking it. It is especially important to avoid mixing codeine with alcohol, benzodiazepines like diazepam, and other opioid drugs

Codeine and Alcohol 

Codeine and alcohol both work by depressing the central nervous system, so when combined they can have a powerful effect that can result in health complications and increase your risk of experiencing an overdose and even death. 

Taken together, alcohol and codeine can cause: 

  • Drowsiness
  • Dizziness
  • Lightheadedness 
  • Difficulty concentrating
  • Fainting
  • Impaired cognitive function 
  • Slowed breathing
  • Low blood pressure
  • Coma
  • Death

These two central nervous system depressants can severely impair your mental state and put your health at serious risk. Because of this, alcohol and codeine should never be mixed. 

Codeine and Benzodiazepine 

Taking codeine with a benzodiazepine like diazepam (still sometimes referred to as valium) is also not a good idea. Like alcohol, both of these drugs are central nervous system depressants so can exacerbate the side effects of both. 

If you take codeine and a benzodiazepine your central nervous system will slow down, which may cause you to become very drowsy, and lethargic and experience symptoms like a slow breathing rate. It can also lead to coma and death if you end up accidentally overdosing. 

Occasionally both of these medications are prescribed together, but this is becoming an increasingly rare practice because of the risk involved. The government now warns healthcare providers to: “only prescribe benzodiazepines (or benzodiazepine-like drugs) and opioids together if there is no alternative”. 

Codeine and Other Opioids

Mixing codeine with other opioids like tramadol, fentanyl, and morphine is not a good idea. Like with alcohol and benzodiazepines, opioids will depress your central nervous system, and taking more than one kind can exacerbate this effect and result in a range of negative health outcomes, from seizures to brain injury and death. 

Codeine Overdose Statistics 

Codeine Abuse & Addiction 

Codeine is an opiate used to treat pain following an injury or chronic pain. It works by affecting the brain’s reward system and creates feelings of pleasure, contentment, and even euphoria. 

Like other opiates, it is addictive and you can end up developing a tolerance to codeine fairly quickly. After a while, you may not actually get the associated high and you’ll require more codeine to simply function.
