Introduction
Opioids are a class of drugs that bind to opioid receptors in the brain and body to reduce pain, but they also slow breathing and can create a powerful sense of relief or euphoria. Some opioids are prescribed medications, such as oxycodone (OxyContin, Percocet), hydrocodone (Vicodin, Norco), morphine, and hydromorphone (Dilaudid). Other opioids are illicit, including heroin, and many people today are exposed to opioids through fentanyl, a synthetic opioid that is far more potent and increasingly present in the drug supply.
Opioids can be appropriate in certain medical settings when used exactly as prescribed, but they carry a high risk for tolerance, physical dependence, and the potential for opioid addiction. With ongoing use, the body adapts quickly, and people often need more to get the same effect. The most serious risk is an opioid overdose, because opioids can slow down breathing without the person realizing how close they are to losing consciousness.
Opioids can feel like they take the edge off fast. The tradeoff is that they can dull you out. Thinking and reaction time slow down, motivation drops, and people can feel foggy, disconnected, or emotionally flat. With higher doses of opioids or opiates, people may nod off mid conversation or drift in and out without realizing it.
In the body, opioids slow down multiple systems. They can cause heavy fatigue, constipation, nausea, itching, pinpoint pupils, and low blood pressure. The most serious effect is that they slow breathing. That is what drives opioid overdose. A person can slip from “relaxed” to unconscious without noticing the warning signs, especially if they are alone.
Mixing opioids with other depressants makes this much more dangerous. Alcohol, benzodiazepines, and certain sleep medications can stack the sedating effects and push breathing down further. Over time, the body builds tolerance, meaning more is needed to get the same effect, and the body can become physically dependent. When opioids wear off, withdrawal can begin, and people often end up using again just to feel normal.
Mixing substances is a major risk. Opioids are already respiratory depressants. When they are combined with alcohol, benzodiazepines, or other sedatives, the effects can stack and breathing can slow more than someone realizes. This is one of the most common pathways to overdose.
Opioid Overdose is a real and ongoing threat. In 2022, the U.S. recorded 107,941 drug overdose deaths, and 81,806 involved an opioid. Even with recent improvements, overdose deaths involving opioids were still estimated at 54,743 in 2024.
Street “pain pills” are often not real pills. Many counterfeit tablets are pressed to look like oxycodone or other prescriptions, but can contain fentanyl or other unregulated substances. The DEA reported that in 2022, 6 out of 10 fentanyl laced counterfeit pills analyzed contained a potentially lethal dose.
Fentanyl drives much of the danger now. CDC notes that in 2023, about 69% of all overdose deaths involved synthetic opioids, primarily illicitly manufactured fentanyl and fentanyl analogs.
How fast tolerance and dependence can build
Tolerance can build with repeated use, meaning you need more to get the same effect, which increases overdose risk. Physical dependence can develop faster than most people expect. Physical dependence is possible within a few days of continuous opioid dosing, depending on the person and the drug.
What withdrawal feels like
When opioids leave the system, the body swings in the opposite direction. People often feel extremely sick, restless, and unable to get comfortable, with cravings that can feel nonstop.
Common opioid withdrawal symptoms include:
o body aches and muscle pain
o chills, sweating, goosebumps
o nausea, vomiting, diarrhea, stomach cramps
o watery eyes, runny nose, yawning, dilated pupils
o anxiety, restlessness, irritability
o insomnia and intense cravings
Timeline
The course depends on the opioid, dose, and how long you have been using. Symptoms can begin 6 to 12 hours after stopping and often peak around 72 hours, with longer acting opioids stretching the timeline.
At Long Island Center for Recovery (LICR), we approach opioid dependence with a person-centered plan and a tailored withdrawal management strategy. The goal is not just to get you through opioid withdrawal, but to stabilize you safely, reduce cravings, lower overdose risk, and help you leave with a recovery plan at discharge.
For many patients, treatment starts with an induction onto buprenorphine, a partial opioid agonist. The goal is stabilization. When you are stabilized, you are no longer stuck in the constant cycle of feeling sick, craving, and trying to catch up. You can sleep, eat, think more clearly, and participate in treatment, which is where real progress starts.
Longer term medication strategies are often part of the plan. This may include maintenance on buprenorphine and, when clinically appropriate, extended-release injectable options. These approaches help reduce relapse risk and can lower the chance of fatal overdose. They also support a safer, prescription-based pathway that is monitored by a healthcare provider.
That said, not every approach is the same. In some cases, a gradual taper and structured titration off buprenorphine may be a better fit. We individualize the opioid addiction treatment strategy based on your history, your goals, your risk level, and what has or has not worked for you in the past. Recovery is not cookie cutter, and neither is our approach.
Day to day, the approach of opioid addiction treatment is steady and consistent. You can expect monitoring, regular check ins, and adjustments based on how you are feeling. Early on, it is common to deal with sleep disruption, mood swings, restlessness, and cravings that come in waves. This is your system recalibrating, and it improves as you stabilize.
Alongside opioid withdrawal management, we focus on the fundamentals that support real recovery. Routine and structure, hydration, nutrition, and sleep hygiene, plus consistent engagement in groups, counseling, relapse prevention work, and 12 step support. Our goal is for you to leave stable, supported, and with a realistic plan you can follow.
Opioid withdrawal can feel intense and miserable, and it is one of the biggest drivers of relapse. It is not usually life threatening in the same way alcohol or benzodiazepine withdrawal can be, but it can become clinically serious, especially if vomiting and diarrhea lead to dehydration. The bigger danger is returning to use after even a short break, because tolerance drops fast and overdose risk goes up.
Buprenorphine is a partial opioid agonist used to stabilize withdrawal and reduce cravings. It helps take you out of the cycle of feeling sick, craving, and trying to catch up. When you are stabilized, you can sleep, eat, think clearly, and actually engage in treatment.
Not necessarily. Many patients benefit from maintenance because it helps reduce relapse and overdose risk, but we do not treat this like a one size fits all decision. Some people do better with a longer term medication plan, and others may be appropriate for a gradual, structured taper. We individualize the approach based on your history, goals, and risk level.
It depends. Opioid withdrawal and stabilization look different for everyone, especially with fentanyl exposure, polysubstance use, and differences in tolerance. Most people feel the worst symptoms in the first few days, but sleep, mood, and cravings can take longer to settle. At LICR, length of stay and next steps are based on your symptoms, stability, safety, and what you need to stay on track after discharge, not a preset day count.
You can expect structured monitoring, regular check ins, and a supportive plan focused on stabilization, sleep, mood, and cravings. Treatment often starts with buprenorphine induction when appropriate, and the plan is adjusted based on how you are doing and what will give you the best shot at staying stable after discharge.
