Opioids are strong medicines your doctor may prescribe to help you manage your pain.
Your doctor might prescribe an opioid medicine to:
Opioid withdrawal happens when you stop taking opioids after you have been taking them regularly. It can also happen if you take another medicine that blocks the opioid from working.
If you take opioids for a period of time, your body gets used to them. When you stop or cut down, you may experience withdrawal symptoms as your body adjusts.
Opioid withdrawal is rarely life-threatening, but it can be very uncomfortable and distressing for you or people close to you.
Opioid withdrawal symptoms may make you feel like you have a bad flu or stomach upset.
Withdrawal symptoms can include:
You may also experience different types of pain during opioid withdrawal, such as joint, bone or muscle pain, abdominal pain or headaches.
You are more likely to have opioid withdrawal symptoms if:
Even if you take an opioid medicine exactly as your doctor prescribes, you can become dependent on it. This means you will experience withdrawal symptoms if you suddenly stop.
If you take an opioid medicine only occasionally or for a very brief period, it's unlikely you will experience withdrawal symptoms.
If you have opioid withdrawal, symptoms will usually peak around 2 to 3 days after you stopped taking opioids, and will usually resolve within 5 to 7 days.
The exact timing and duration of your symptoms will depend on the type and dose of opioid you are taking and how long you've been using it.
For example, if you are taking prescribed opioids that work quickly, such as oxycodone, or if you are using the drug heroin, you are likely to experience withdrawal symptoms 6 to 12 hours after taking your last dose.
If you are taking methadone or other opioids that are released more slowly in your body, you are likely to experience withdrawal symptoms about 1 to 3 days after taking your last dose. The symptoms are usually not as severe as for fast-acting opioids, but they may last for a few weeks.
Always talk to your doctor or pharmacist before you stop or reduce your opioid medicines.
If you want to stop taking your opioid medicine, speak with your doctor for advice. Your doctor will slowly lower your dose so you can reduce your chance of withdrawal symptoms.
This process is called tapering. Your doctor will work with you to create a day-by-day or week-by-week plan to reduce your dosage.
Your plan will depend on how urgent it is for you to stop taking opioids and how long you've been taking them. Your doctor may recommend other medicines to help you manage any opioid withdrawal symptoms.
If you do develop opioid withdrawal symptoms, your doctor can prescribe medicines or give you tips to help manage your symptoms.
If you do develop withdrawal symptoms, remember that they are temporary and not usually dangerous.
Here are some tips to manage opioid withdrawal:
Don't let fear of withdrawal prevent you from stopping or reducing your opioid use. Speak with your doctor about how you can prepare and manage your symptoms.
Your doctor may prescribe you some of these medicines to help you manage your symptoms:
Your doctor may prescribe these medicines for about a week, depending on your circumstances.
In some cases, your doctor may prescribe methadone and buprenorphine. These opioids can be used to replace other more harmful opioids. Your doctor might prescribe these for an extended period of time to control your symptoms and minimise harmful opioid use, and may discuss stopping them at a later date.
If you have chronic (long-term) pain that is not caused by cancer, over time, you will experience less benefit from opioid pain medicine, and have more chance of harm. It's a good idea to talk to your doctor about coming off opioids.
Taking opioids can lead to:
As your dose of opioid medicine increases, so does the risk of harmful side effects.
You should see your doctor if you:
