It’s impossible to stop opioid withdrawal symptoms by using over-the-counter (OTC) medications. Physical dependence causes opioid withdrawal. When you quit abruptly, your body can’t perform properly. No over-the-counter medication can fix that.
Experts consider opioid withdrawal a life-threatening condition.[1] It’s always best to get professional help to overcome your opioid-use disorder (OUD). Your team will use medications like Suboxone to help you stop misuse of addictive drugs.
Your team may also use OTC medications to ease discomfort. While using these medications alone (instead of pairing them with Suboxone) isn’t recommended, understanding what these therapies are and how they work could help you in your recovery.
When people take opioid drugs for long periods, they develop withdrawal symptoms when they quit the drug abruptly or attempt to reduce their dose.
Common symptoms of opioid withdrawal can be placed into the following groups:[5]
Withdrawal symptoms are sometimes described as “flu-like,” but they can be excruciating. Adding OTC remedies to the mix could help your team keep you comfortable while your body adjusts to a life without drugs.

OTC drugs typically used in treatment include the following:
Opioid withdrawal symptoms can be so overwhelming that you’re tempted to return to drug misuse.[2] This can lead to changes in tolerance and increased risk of overdose.
Some people grow so distressed during opioid withdrawal that they consider suicide.[3] The problem is so serious that the U.S. Food and Drug Administration (FDA) requires prescription painkiller labels to state withdrawal risks clearly.
Medications for Addiction Treatment (MAT) can stabilize chemical imbalances within your brain.[4] Physical withdrawal symptoms fade, as do your drug cravings. Therapies like this can not only help you to get abstinent during acute withdrawal, but they can help you stay abstinent long term.
Don’t take a risk with your health and try detoxing with over-the-counter meds alone: Get professional help instead, and consider if MAT – including methadone or Suboxone – would be right for you.
These are some of the questions people often ask about the role of OTC medications during opioid withdrawal:
Can I use OTC medications instead of methadone or buprenorphine for withdrawal? No. Experts say that opioid withdrawal is a life-threatening condition that should be treated with prescription solutions like methadone or buprenorphine.[1] OTC medications can work in tandem, easing acute symptoms, but they’re not a replacement for MAT drugs.
Why do I need OTC medications if I’m using methadone or buprenorphine? You may not need them. When you enroll in a detox program, your team will administer your medications and watch your symptoms. You may not need additional therapies at all. But if you do need more help, your team can administer additional medications.
I’ve heard I can use loperamide instead of MAT. Is that true? Many websites and drug forums claim that loperamide is a safe alternative to methadone. Sometimes, posts suggest that people can use megadoses of the drug to get high. Researchers say the drug can be toxic at high doses and can cause problems like respiratory depression.[10] It’s not a safe alternative to MAT.
