Review our dictionary for up-to-date information about common opioids and their potential side effects.
Buprenorphine
FDA-approved medication used to reduce opioid withdrawals and cravings.
How It Works
Buprenorphine is an FDA-approved opioid medication that reduces withdrawal symptoms and cravings. This medication has less effect on one’s ability to breathe and does not cause feelings of pleasure like other opioids. Buprenorphine is often combined with naloxone, another OUD medication, to increase safety in case of an overdose. The prescriber has to have special training to recommend this medication.
Side Effects
- Nausea or vomiting
- Constipation, or difficulty pooping
- Muscle aches or cramps
- Cravings
- Sleeplessness
- Discomfort
- Irritability
- Fever
Those who experience an allergic reaction from buprenorphine, such as hives or swelling in the face, lips, or throat, should seek medical help immediately.
Brand Names
Bunavail, Suboxone, or Zubsolv
How To Get It
The first dose of buprenorphine can be given in a doctor’s office after the patient has not used opioids for approximately 4-6 hours and is experiencing withdrawal symptoms. This is important because buprenorphine can cause someone to go into withdrawal if they aren’t already. Medical monitoring ensures there are no significant side effects. Home induction is also possible, if a person has taken buprenorphine in the past. Dose is adjusted as needed.
Codeine
Opioid medicine commonly used to relieve pain and coughing.
How It Works
Codeine is an opioid used in medical settings to treat mild to severe pain. It is also used, usually in combination with other medications, to reduce coughing. Codeine (alone or in combination with other medications) comes as a tablet, a capsule, and a solution (liquid) to take by mouth.
Side Effects
- Headache
- Stomach pain
- Irritation
- Seeing things or hearing voices that do not exist
- Fever
- Sweating
- Confusion
- Fast heartbeat
- Shivering

- Diarrhea
Drinking alcohol during your treatment with codeine also increases the risk that you will experience these serious side effects.
Brand Names
Codeine is commonly found in many cough or cold medications. If you are taking a codeine combination product, be sure to read information about all the ingredients in the product you are taking. You can also talk to your doctor or pharmacist for more information.
Fentanyl
Man-made opioid used to treat severe pain, but can cause overdose when abused.
How It Works
Legal fentanyl is a man-made opioid pain reliever that is 50 to 100 times more powerful than morphine and can only be prescribed by a doctor. Just a tiny amount of illegally made fentanyl is enough to cause death. Many opioids sold on the street are often laced with fentanyl. Fentanyl should only be used when prescribed by a doctor.

Heroin
Illegal and highly dangerous opioid made from morphine.
How It Works
Heroin is a highly addictive and fast acting opioid extracted from certain poppy plants. This drug is processed from morphine and comes in a white or brownish powder, or a black sticky substance. People who use heroin experience a rush of pleasure followed by a deep state of drowsiness. Heroin is often mixed with other drugs or substances, so users are usually unaware how much actual heroin is being used, increasing the likelihood of overdose.
Side Effects
- Drowsiness
- Small pupils

- Slowed/shallow breathing
- Feeling of having heavy legs
Street Names

How It Works
Methadone is a medication used to treat opioid addiction by tricking the brain into thinking it is still getting the desired opioid, usually heroin. When used correctly, people do not get high from using this medication, but they will avoid withdrawal symptoms. While methadone may cause a mild feeling of pleasure, it blocks the other usual effects of opioids. It is important to work with your doctor to use methadone correctly, as it can be harmful if misused.

- Difficulty breathing
- Shallow breathing

A medical professional will provide methadone in a specialized opioid treatment program (OTP) after you have been checked out by a doctor.
Morphine
Natural opioid used to treat pain, but can be highly addictive when abused.
How It Works
Morphine is a natural opioid often used in medical settings to treat extreme physical pain. This drug can be taken in a tablet/capsule form, or an injectable liquid form.

NORA Saves is another free resource from the CT Department of Public Health offering information on how to use naloxone and where you can get it in your community. There are also many pharmacies in Connecticut that are certified to prescribe naloxone. It is strongly recommended to call ahead of time to check if naloxone is available. If it is not available at that time, most certified pharmacies can get the medication within 24 hours. For information on naloxone training and distribution events, please visit Opioid Services (ct.gov).
Naltrexone
FDA-approved medication that can prevent alcohol or drug relapses.
How It Works
Naltrexone is an FDA-approved medication used to treat both alcohol and opioid addiction. When treating opioid use disorder, this medication works by blocking the effects of opioids so that if a person uses an opioid, they do not feel high. Naltrexone is not commonly misused since it causes no effects, but it must be taken by mouth daily or injected monthly to prevent cravings from returning.
Side Effects
- Nausea or vomiting
- Diarrhea
- Headache

- Restlessness or tiredness
- Joint or muscle pain
Seek a medical professional immediately for any of the following:

Opioids
Opioids are a class of drugs that are made from, or copy, natural substances found in the opium poppy plant. Opioid drugs include prescription pain medicine and illegal drugs. Proper medical use of opioids can help with pain relief, but sometimes opioids are abused for the high feeling they produce.
Other Names
Opiates, painkillers, narcotics

How It Works
Oxycodone is an opioid that is derived from thebaine, a part of the poppy plant. This drug is often used to treat severe pain and makes the user feel relaxed.

Thebaine
Part of the opium poppy plant that can be extracted and used in opioid medications.
How It Works
Thebaine is an alkaloid, a part of a natural plant that can affect the normal way humans or animals behave. Thebaine is part of the latex in the opium poppy plant and it is produced in the capsule as well as in the stems and leaves. If the poppy plant has not been processed or “washed” to remove alkaloids like thebaine, its poppy seeds may have higher amounts on their coats. These seeds are often abused for their opioid effects. Thebaine is also often extracted to be used in opioid medications, such as naloxone, naltrexone, and buprenorphine.
Side Effects
- Feeling of pleasure
- Slowed/shallow breathing
- Constipation
- Addiction
Tramadol
