Codeine Overdose | Warning Signs, Symptoms, & Treatment
Codeine is an opioid that acts as a painkiller and cough suppressant by impacting the central nervous system.
It appears in many prescription and over-the-counter medications, including codeine cough syrup and Tylenol with Codeine.
It’s important to follow your health care provider’s instructions when using codeine and acetaminophen products. If you don’t, you face the risk of overdose. This medical emergency can be life-threatening.
Who’s At Risk For Codeine Overdose?
You’re more likely to overdose on codeine if you:
- develop a tolerance to it, which means you need increasingly higher doses of the drug to achieve the desired effects
- become physically dependent on it, which means your body relies on the drug to function normally
- become addicted to it, which means you regularly crave the drug and feel unable to stop using it
You face a higher risk of tolerance, physical dependence, and addiction if you were prescribed codeine for more than several weeks or if you abuse it.
Abuse occurs when you use codeine without following your doctor’s instructions so you can achieve a “high” (a sense of relaxation, sedation, and euphoria).
Some people also abuse codeine by drinking codeine cough syrup mixed with soda and hard candy (a mixture commonly known as “purple drank, “lean,” or “sizzurp”).
Warning Signs Of Codeine Overdose
If you’re concerned that you or someone you love might overdose on codeine, there are a number of warning signs you can watch for.
Side Effects Of Codeine
First, check if you or your loved one frequently experiences the side effects of codeine. The most common side effects are headache, constipation, stomach pain, and trouble urinating.
Less common, more serious side effects include:
- nausea and/or vomiting
- loss of appetite
- hallucinations (seeing, hearing, or feeling things that aren’t there)
- poor coordination
If you or your loved one experiences any of these serious side effects, seek medical advice as soon as possible.
Signs Of Codeine Abuse & Addiction
You should also look for signs of abuse and addiction; as stated above, people who abuse or are addicted to codeine face a higher risk of overdose.
Addiction warning signs may include:
- withdrawing from friends and family members to spend more time using codeine
- avoiding responsibilities at work or school to spend more time using codeine
- taking higher and higher doses of codeine over time
- visiting multiple doctors or pharmacies to get multiple prescriptions of codeine, also known as “doctor shopping”
- wanting to stop using codeine but feeling unable to do so
In addition, a person who is addicted to codeine might experience withdrawal symptoms when they try to stop using the drug, which may include:
- enlarged pupils
- watery eyes
- runny nose
- trouble sleeping
Codeine Overdose Symptoms
Codeine overdose can occur when you take too much codeine, and the most common symptoms may include:
- nausea and vomiting
- cold, clammy skin
- muscle twitches
- bluish lips and/or fingernails
- breathing problems, such as noisy, slow, or shallow breathing
- weak pulse
- low blood pressure
- loss of consciousness
If you or someone you know experiences these symptoms, call 911 or the National Poison Control Center immediately.
You’ll need to provide the name, age, weight, and condition of the individual who overdosed, along with the name and amount of the product ingested.
The person you reach will send for emergency medical help to reduce the risk of brain damage and death.
Treatment For Codeine Overdose
Someone who overdoses on codeine will require immediate treatment to reverse the overdose as well as aftercare to prevent a future overdose.
Opioid Overdose Reversal Medication
To reverse a codeine overdose, the paramedics or emergency room doctors will administer a medication called naloxone.
Also known as Narcan or Evzio, naloxone is an opioid antagonist. That means it can quickly reverse and block the effects of codeine and other opioids.
According to the United States Food and Drug Administration (FDA), naloxone can be administered via injection or nasal spray. Both methods can rapidly restore normal breathing to a patient whose breathing has been compromised due to a codeine overdose.
After the patient responds to naloxone, the paramedics or emergency room doctors will closely monitor the patient’s vital signs. They’ll also gently explain what is happening and keep the environment as comfortable as possible.
When you experience a codeine overdose, your doctor will likely recommend addiction treatment at a drug rehab center.
At the rehab center, a team of medical professionals will help you safely detox from codeine. They may also prescribe medications such as methadone or buprenorphine to decrease withdrawal symptoms and prevent relapse.
Treatment may also include behavioral therapy. In this form of counseling, a licensed therapist will teach you important coping skills to avoid relapse and address any mental health challenges you face.
