Types of Pain Killers
Types of Pain Killers
Painkillers are classified into types such as acetaminophen, NSAIDs, opioids, and corticosteroids, each used for different levels of pain relief. Acetaminophen is for mild pain, NSAIDs reduce inflammation, opioids treat severe pain, and corticosteroids manage inflammation.

Pain killers come in various forms, each designed to treat different types of pain and inflammation. Here’s a breakdown of the most common types:
1. Acetaminophen (Tylenol)
Acetaminophen is a popular over-the-counter option for mild to moderate pain relief. It’s often used for headaches, fever, and muscle aches. One of its main benefits is that it’s gentle on the stomach, making it a good option for those with sensitive digestive systems.
2. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
NSAIDs work by reducing both pain and inflammation, making them helpful for conditions like arthritis or muscle strains. Common examples include:
- Aspirin
- Ibuprofen (Advil, Motrin)
- Diclofenac
These are available over the counter or by prescription, depending on the strength needed.
3. Opioids
Opioids are powerful pain relievers prescribed for severe or chronic pain, such as pain from surgeries, injuries, or terminal illnesses. Examples include:
- Morphine
- Codeine
- Oxycodone
4. Corticosteroids
Corticosteroids help reduce inflammation by suppressing the immune system’s response. They’re often used for conditions involving swelling and inflammation, such as arthritis or allergies. Common corticosteroids include:
- Hydrocortisone
- Prednisone
- Methylprednisolone
These drugs can be taken orally, injected, or applied topically, depending on the condition.

Morphine
Morphine is a powerful medication used to relieve severe pain. It belongs to a group of medicines called opioids, which work by targeting specific receptors in the brain and spinal cord. By doing this, morphine reduces the feeling of pain, making it easier for people to manage extreme discomfort.

- Acute pain from injuries
- Pain following surgery
- Pain caused by cancer
- Long-term severe pain
Side Effects
Like many strong pain killers, morphine can cause side effects. Some common ones include:
- Drowsiness or sleepiness
- Constipation
- Nausea
- Feeling dizzy
Oxycodone
Oxycodone is a powerful pain-relieving medicine that belongs to the opioid class of drugs. It is used to manage moderate to severe pain and comes in two forms: immediate-release for quick pain relief and extended-release for long-lasting relief over time.
Uses
Doctors often prescribe oxycodone for:
- Long-term chronic pain
- Severe pain from conditions like cancer
- Intense pain due to serious injuries
Side Effects
Like other opioids, oxycodone can cause side effects. Some of the common ones include:

Hydromorphone is used to treat:
- Severe pain that requires ongoing treatment
- Post-surgery pain
- Cancer-related pain
- Other cases where typical pain relievers don’t provide enough relief
Side Effects
Common side effects of hydromorphone include:
- Drowsiness or sedation
- Nausea

Tramadol is commonly used to treat:
- Moderate to moderately severe pain
- Conditions like arthritis
- Pain relief after surgery or injury
Side Effects
Some common side effects of tramadol include:
- Nausea
- Dizziness

Uses
Buprenorphine is commonly prescribed for:
- Long-term (chronic) pain management
- Treating opioid dependence in recovery programs, helping reduce cravings and withdrawal symptoms
Side Effects
While buprenorphine is generally safer than full opioids, it can still cause side effects, including:
- Headaches
- Nausea

Methadone
Methadone is a long-lasting opioid that is used for pain relief and also plays a key role in helping people recover from opioid addiction. Its unique ability to stay in the body longer helps manage pain and withdrawal symptoms effectively.
Uses
Methadone is commonly used for:
- Managing long-term (chronic) pain and nerve-related (neuropathic) pain
- Treating opioid dependence, helping to reduce cravings and withdrawal symptoms in recovery programs
Side Effects
Like other opioids, methadone can cause side effects such as:
- Difficulty breathing (respiratory depression)
- Nausea
- Dizziness
- Risk of addiction, especially with long-term use
Hydrocodone
Hydrocodone is a semi-synthetic opioid commonly prescribed to manage moderate to severe pain. It is often combined with non-opioid pain relievers like acetaminophen or ibuprofen to boost its effectiveness.
Uses

Common side effects of hydrocodone include:
- Feeling sleepy or drowsy
- Nausea
- Constipation
- In higher doses, it can slow down breathing (respiratory depression) and lead to addiction if not used properly.
Diclofenac
