Key Takeaways:
- Medications for opioid withdrawal reduce symptoms such as nausea, muscle aches, and cravings to support safer detox.
- Opioid addiction medication (like buprenorphine, methadone, naltrexone) are evidence-based tools used in treatment settings.
- A medical detox plus residential therapy offers the safest, most effective environment to begin recovery.
Opioid addiction is difficult and dangerous to manage alone. Many people feel uncertain about where to start or which treatments actually work. At the San Diego Wellness Center, we offer medical detox and residential care that focuses on safety, comfort, and lasting recovery. Medications for opioid withdrawal can ease symptoms and stabilize the body, while opioid addiction medications support long-term recovery. This article explains how these medications work, what to expect, and how they fit into effective treatment plans.
What Are Opioid Withdrawal Symptoms
When someone stops or reduces opioid use, the body reacts with a set of physical and psychological changes as it adapts to the absence of the drug. These are opioid withdrawal symptoms. Common symptoms include:
- Muscle aches and pains
- Nausea, vomiting, diarrhea
- Runny nose, tearing, sweating
- Agitation, restlessness
- Insomnia and anxiety
- Cravings for opioids
Symptoms typically begin within hours to a day after the last dose (depending on which opioid was used), increase over a few days, and gradually subside over one to two weeks in milder dependence. In more severe dependence, withdrawal may last longer or require more support.
Because withdrawal can be intense and dangerous in some individuals, medical supervision is critical in many cases. Medication can ease symptoms, reduce discomfort, and lower the risk of relapse or complications.
What Are Medications Used for Opioid Withdrawal
Medical professionals use several medications to help manage withdrawal, ease discomfort, and support stabilization. Their goals are to reduce unpleasant symptoms, prevent dehydration or medical complications, and transition patients safely into longer-term treatment (often combined with counseling). Below are the main categories of medications used:
Partial Agonists & Agonist Replacement: Buprenorphine and Methadone
Buprenorphine (with or without naloxone)
Buprenorphine is a partial opioid agonist. It attaches to opioid receptors but activates them less intensely than full agonists. This reduces cravings and withdrawal symptoms without producing the full “high” of stronger opioids. Often this is combined with naloxone (e.g., Suboxone) to deter misuse.
Methadone
Methadone is a full agonist, but when given under controlled settings, it helps maintain stability by preventing withdrawal and reducing opioid use without repeated intoxication. Methadone must be administered under strict supervision in certified clinics.
These medications help people gradually reduce their dependency, or in some cases stabilize indefinitely under care, while receiving counseling and behavioral therapies.
Opioid Antagonists: Naltrexone
Naltrexone (oral or injectable, e.g., Vivitrol)
Naltrexone blocks opioid receptors entirely; if someone uses an opioid while on naltrexone, they will not feel the rewarding effect. It is not used during acute withdrawal (because it can precipitate withdrawal), but after detox, it can help prevent relapse. The injectable form (monthly shot) is often used in outpatient settings.
Symptomatic Medications
These do not act on opioid receptors but help control individual symptoms during withdrawal:
- Anti-nausea drugs (e.g., ondansetron)
- Antidiarrheal agents (e.g., loperamide)
- Clonidine (to reduce autonomic hyperactivity: sweating, high blood pressure)
- Sleep aids or sedatives (short-term, carefully supervised)
- Over-the-counter pain relievers (e.g., acetaminophen, ibuprofen)
In a medical detox setting, clinicians tailor these supportive medications to each patient’s symptoms.
How Opioid Addiction Medication Works in Treatment
To know what opioid addiction medication is and how it fits into care, it helps to see when it is used, how it helps, and what challenges exist.
Starting During Medical Detox
When a person enters medical detox or inpatient care, the first goal is stabilization. Physicians may begin buprenorphine or methadone early in the detox process to blunt withdrawal discomfort. The dose is adjusted carefully to avoid sedation while keeping cravings down. Over days, the patient’s system gradually adapts to a stable dose.
During detox, symptomatic medications are given alongside addiction medications to address nausea, diarrhea, insomnia, and other discomforts. Vital signs, hydration status, and mental state are monitored to ensure safety.
Maintenance and Tapering
After detox, some patients remain on a maintenance dose of buprenorphine or methadone for an extended period, sometimes months or years. The rationale is that long-term stabilization reduces the risk of relapse, supports psychosocial recovery, and allows the person to rebuild their life. Others may gradually taper under medical supervision when they reach stability.
If a person is fully detoxed, naltrexone may be introduced to block the effects of opioids and discourage relapse.
Combining with Therapy and Support
Medication alone is rarely sufficient. Opioid addiction medication should be integrated with cognitive behavioral therapy, support groups, counseling, and education to help people rebuild skills, manage triggers, and restructure their life. In residential settings, patients receive 24/7 support, therapy, group work, life skills training, and oversight.
Risks, Safety, and Monitoring
All medications have risks. Key considerations include:
- Overdose risk if combined with other sedatives or alcohol
- Misuse or diversion (especially for methadone or buprenorphine)
- Precipitated withdrawal if a blocker (like naltrexone) is given too early
- Side effects (constipation, headache, sedation)
- Adherence challenges
Because of these risks, medication should always be prescribed in licensed treatment settings, with regular monitoring, drug screening, counseling, and follow-up care.
What Does Opioid Addiction Look Like
Before or during treatment, it is helpful to recognize how opioid addiction often presents in real life. Recognizing the pattern can help people accept that help is needed and reach out. Signs and symptoms may include:
Behavioral Signs
- Going to the doctor “shopping” for prescriptions
- Taking higher doses or more frequent use to get the same effect
- Using opioids despite negative consequences (health, legal, relationships)
- Loss of control over how much is used
- Secretive behavior, withdrawal from friends or family
Physical and Psychological Signs
- Tolerance builds: needing more to feel the effect
- Withdrawal symptoms on cessation
- Energy slumps, depression, and anxiety
- Neglected appearance, hygiene, and weight loss
- Frequent infections, slowed breathing, and constipation
These signs do not prove addiction by themselves, but when multiple signs persist and interfere with daily life, they may indicate opioid use disorder (addiction). At that point, medical care and therapy are essential.
Common Medications for Opioid Withdrawal & Addiction
| Medication Type | Common Example(s) | Role / Use Stage | Key Benefits | Major Risks / Considerations |
| Partial agonist | Buprenorphine / Suboxone | During detox and maintenance | Reduces cravings, safer than full agonists | Risk of misuse, must be monitored |
| Full agonist replacement | Methadone | During stabilization / maintenance | Strong symptom control, proven track record | Requires clinic dosing, overdose risk |
| Opioid antagonist | Naltrexone (oral, injectable) | After full detox | Blocks opioid effects, supports abstinence | Cannot start too early, precipitated withdrawal risk |
| Symptomatic support | Clonidine, anti-nausea, analgesics | During acute withdrawal | Eases specific symptoms | Side effects, must combine with primary meds |
Choosing the Right Medication Option
Not every person is a candidate for every medication. Clinicians decide based on:
- Severity and duration of opioid use
- Types of opioids used (short-acting vs long-acting)
- Medical history, liver or kidney status
- Co-occurring mental health diagnoses or other substance use
- Prior response to medications
- The patient’s commitment to therapy, follow-up, and safety

Frequently Asked Questions
Are medications for opioid withdrawal addictive?
Medications like buprenorphine and methadone activate opioid receptors, so there is a potential for dependency. But when used under supervision, they are safer and often less addictive than abusing illicit opioids.
Can I take naltrexone immediately after the last opioid dose?
No. If you take naltrexone too soon, it can trigger severe withdrawal. You must wait until you are fully detoxed, often 7–10 days (or longer), before starting it.
Do I have to take medication forever?
Not necessarily. Some people use medication long-term; others taper off when stable. The decision is individualized, based on progress, risk factors, and monitoring.
What if I relapse while on medication?
Medication helps reduce risk, but relapse can happen. If it does, your clinician may adjust the dose, switch medications, or intensify therapy. It is not a failure—just a sign you need more support.
Is residential treatment necessary when using these medications?
While some can begin medication in outpatient settings, residential treatment ensures 24-hour care, supervision, therapy access, and safety during the vulnerable early days of withdrawal.
