How Opioids Work
Opioid drugs bind to opioid receptors in the brain, spinal cord, and other areas of the body. They tell your brain you’re not in pain.
They are used to treat moderate to severe pain that may not respond well to other pain medications.
- Codeine (only available in generic form)
- Fentanyl (Actiq, Duragesic, Fentora, Abstral, Onsolis)
- Hydrocodone (Hysingla, Zohydro ER)
- Hydrocodone/acetaminophen (Lorcet, Lortab, Norco, Vicodin)
- Hydromorphone (Dilaudid, Exalgo)
- Meperidine (Demerol)
- Methadone (Dolophine, Methadose)
- Morphine (Kadian, MS Contin, Morphabond)
- Oxycodone (OxyContin, Oxaydo)
- Oxycodone and acetaminophen (Percocet, Roxicet)
- Oxycodone and naloxone
Your doctor can prescribe most of these drugs to take by mouth. Fentanyl is available in a patch. A patch allows the medication to be absorbed through the skin.
Working With Your Doctor
You’ll need a prescription from your doctor before you start taking opioids. The doctor can adjust the dose as needed to help control pain.
You may receive around-the-clock doses to manage pain throughout the day and night. And your doctor may prescribe opioids to be taken “as needed” in case you have “breakthrough” pain — a flare of pain that you get despite round-the-clock doses.
While you’re on opioid pain medications, check in with your doctor regularly. Your doctor will need to know:
- How your pain is responding to the drug
- Whether you’re having any side effects
- Whether you have any potential interactions or medical conditions that could make you more likely to have side effects, such as sleep apnea, alcohol use, or kidney problems
- Whether you’re taking the drug properly
Opioid Side Effects
One of the reasons why your doctor needs to manage pain medications so closely is that they can cause side effects, such as:
- Nausea and vomiting
Opioids can be dangerous if you take them with alcohol, or with certain drugs such as:
- Some antidepressants
- Some antibiotics
- Sleeping pills
- Prescription drugs
- Over-the-counter drugs
- Herbal supplements
Opioid Tolerance and Addiction
After taking opioid pain medication for a while, you might find that you need more and more of the drug to achieve the same effect in easing pain. This is called tolerance. It’s not the same as addiction, which involves a compulsive use of a drug.
When you use opioid medication over an extended period of time, you can have dependence. This can happen when your body becomes so used to the drug that if you abruptly stop taking it, you get withdrawal symptoms such as:
- Diarrhea, nausea, and vomiting
- Muscle pain
You can also get a serious addiction to opioid pain medications. People who are addicted compulsively seek out the pain medications. Their behavior usually leads to negative consequences in their personal lives or workplace. They might take someone else’s pills or buy them off the street, which is especially dangerous since those drugs are often laced with lethal amounts of fentanyl.
If you are having a problem with addiction, you need to see your doctor or an addiction specialist.Should You Take Opioid Pain Medications?
Opioids can make a dramatic difference to people with moderate to severe pain. These drugs can be an effective therapy — as long as you use them safely and follow your doctor’s instructions carefully.
