Opioids are strong pain medicines. Examples of prescription opioids include hydrocodone, oxycodone, fentanyl, and morphine. Heroin is an example of an illegal opioid.
Your body gets used to opioids if you take them all the time. This is called physical dependence. And when you stop using opioids or use less, you go through withdrawal.
Withdrawal symptoms can include nausea, sweating, chills, diarrhea, stomach cramps, and muscle aches. Withdrawal can last up to several weeks. It depends on which opioid you took and how long you took it. You may feel very ill, but you probably aren't in medical danger.
Withdrawal isn't easy, but there are things you can do to help you cope with the symptoms. You will feel a little bit better each day as your body adjusts and heals itself.
Remember after you stop taking an opioid, even for a short time, your body gets used to not having this type of drug. If you return to taking the same amount of an opioid as you did before you stopped, you could be at a higher risk for overdose.
If a person who is physically dependent on heroin stops taking it or uses less, they will have withdrawal symptoms within a few hours. Symptoms can include anxiety, nausea, sweating, and chills. The person may also have diarrhea, stomach cramps, and muscle aches. These symptoms may be mild or severe. They may feel like the flu (influenza).
Withdrawal can last from weeks to months. A person who has stopped using heroin will feel very ill for several days. A doctor may prescribe medicine to help relieve the symptoms.
Cravings for heroin usually go away over the next few months. But they may suddenly come back months later.
