Paracetamol vs Ibuprofen: Which Should You Reach For?
Paracetamol and ibuprofen are among the most commonly used pain relievers in Cambodia, but they work differently. Learn when each medicine is the better choice, who should avoid them, and how to use them safely.
Pain and fever are common symptoms caused by infections, headaches, muscle aches, dental problems, or minor injuries. Many Cambodian families keep paracetamol or ibuprofen at home, but choosing the right medicine is not always straightforward.
Although both medicines help reduce pain and fever, they work differently and are suitable for different situations. Understanding these differences can help you make safer and more effective decisions for yourself and your family.
What is Paracetamol?
Paracetamol (also called acetaminophen in some countries) is a medicine used to relieve:
- Fever
- Headaches
- Toothache
- Mild to moderate pain
- Cold and flu symptoms
Paracetamol works by affecting the brain’s pain and temperature regulation but does not significantly reduce inflammation.
Advantages of Paracetamol
- Effective for reducing fever
- Gentle on the stomach
- Suitable for most adults and children when used correctly
- Often recommended during pregnancy after medical advice
- Good choice for people with stomach ulcers
Possible Risks
Paracetamol is generally very safe when taken at the recommended dose. However, taking too much can cause serious liver damage.
Always:
- Follow the dosing instructions
- Avoid taking multiple medicines containing paracetamol at the same time
- Limit alcohol intake while using paracetamol
What is Ibuprofen?
Ibuprofen belongs to a group of medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).
It helps relieve:
- Fever
- Pain
- Inflammation
- Swelling
Ibuprofen is especially useful when pain is caused by inflammation.
Common Uses
Ibuprofen may work better than paracetamol for:
- Sprains and strains
- Sports injuries
- Back pain
- Arthritis
- Menstrual cramps
- Dental pain with swelling
Advantages of Ibuprofen
Ibuprofen provides pain relief while also reducing inflammation, making it particularly helpful for injuries and swollen tissues.
It often lasts between 6–8 hours depending on the dose.
Possible Risks of Ibuprofen
Ibuprofen is not suitable for everyone.
It may increase the risk of:
- Stomach irritation or ulcers
- Gastrointestinal bleeding
- Kidney problems
- Worsening asthma in some individuals
- Increased cardiovascular risk with prolonged high-dose use
Avoid ibuprofen unless advised by your healthcare professional if you:

Key Takeaway
Paracetamol and ibuprofen are both effective medicines for relieving pain and fever, but they are not interchangeable.
