When it comes to managing pain and reducing fever, two commonly used over-the-counter medications are ibuprofen and paracetamol. Both medications are widely available and offer effective relief for various conditions. However, there are some key differences between the two that are important to understand. In this article, we will delve into the difference between ibuprofen and paracetamol, exploring their mechanisms of action, uses, side effects, and more. Let’s dive in!

Difference Between Ibuprofen and Paracetamol

Ibuprofen and paracetamol are both analgesics and antipyretics, meaning they help relieve pain and reduce fever. However, they belong to different classes of medications and work in different ways within the body.


Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting the production of certain chemicals in the body called prostaglandins. These prostaglandins play a role in the inflammation process, contributing to pain and fever. By blocking their production, ibuprofen helps reduce inflammation, relieve pain, and lower fever.

Uses of Ibuprofen

  • Pain relief: Ibuprofen is commonly used to relieve mild to moderate pain, such as headaches, dental pain, menstrual cramps, and musculoskeletal pain.
  • Inflammation reduction: Due to its anti-inflammatory properties, ibuprofen is also used to reduce swelling and inflammation associated with conditions like arthritis and sports injuries.
  • Fever reduction: Ibuprofen can effectively lower fever in individuals of all ages.


Paracetamol, also known as acetaminophen, is classified as an analgesic and antipyretic but lacks significant anti-inflammatory properties. It works by inhibiting the production of prostaglandins in the brain that are responsible for pain and fever. Although the exact mechanism is not fully understood, paracetamol is believed to work primarily within the central nervous system.

Uses of Paracetamol

  • Pain relief: Paracetamol is commonly used to relieve mild to moderate pain, including headaches, toothaches, and muscle aches. It is also effective in managing pain associated with conditions like osteoarthritis.
  • Fever reduction: Paracetamol is widely used to lower fever in adults and children.

Key Differences

  1. Mechanism of action: Ibuprofen works by inhibiting the production of prostaglandins in the body, while paracetamol primarily works within the central nervous system to block pain and fever signals.
  2. Anti-inflammatory properties: Ibuprofen has significant anti-inflammatory effects, making it effective for reducing inflammation associated with conditions like arthritis. Paracetamol, on the other hand, lacks significant anti-inflammatory properties.
  3. Side effects: Ibuprofen can irritate the stomach lining and may cause gastrointestinal side effects such as indigestion and stomach ulcers. Paracetamol is generally well-tolerated but can cause liver damage if taken in excessive amounts or combined with alcohol.
  4. Suitable for different age groups: Ibuprofen is generally safe for children aged three months and above, while paracetamol is commonly used for children of all ages, including infants.
  5. Availability: Ibuprofen is available in various forms, including tablets, capsules, and topical gels, while paracetamol is available in tablets, capsules, syrups, and even suppositories for rectal administration. Both medications can be easily obtained over the counter without a prescription.
  1. Interactions with other medications: Ibuprofen may interact with certain medications, such as blood thinners and selective serotonin reuptake inhibitors (SSRIs), increasing the risk of bleeding or stomach ulcers. Paracetamol has fewer interactions with other medications, making it a safer choice for individuals taking multiple medications.
  2. Duration of action: Ibuprofen has a longer duration of action compared to paracetamol. While paracetamol may provide relief for up to 4-6 hours, ibuprofen’s effects can last for 6-8 hours.
  3. Allergic reactions: Some individuals may be allergic to ibuprofen or paracetamol. It is essential to be aware of any signs of an allergic reaction, such as rash, swelling, or difficulty breathing, and seek medical attention if necessary.
  4. Dosage and frequency: The recommended dosage and frequency of Ibuprofen and Paracetamol Suspension may vary depending on the age, weight, and condition being treated. It is crucial to follow the instructions provided by healthcare professionals or read the package insert carefully.
  5. Overdose risk: Taking excessive amounts of either ibuprofen or paracetamol can be harmful and lead to serious complications. It is vital to adhere to the recommended dosages and avoid combining these medications without medical advice.

Q. Can ibuprofen and paracetamol cause addiction?
No, neither ibuprofen nor paracetamol have addictive properties. They are not considered addictive substances.


In summary, while ibuprofen and paracetamol are both effective in relieving pain and reducing fever, they have distinct differences in their mechanisms of action, anti-inflammatory properties, side effects, and suitability for different age groups. Understanding these differences can help individuals make informed decisions
