EnterLibrary -- When it comes to managing pain and reducing fever, various over-the-counter medications are at our disposal. Three commonly used drugs for these purposes are paracetamol, mefenamic acid, and ibuprofen. Each has its unique characteristics, and understanding the differences among them is crucial for making informed decisions about their usage. In this article, we will explore the distinctions between paracetamol, mefenamic acid, and ibuprofen to help you choose the right option for your needs.
Composition and Mechanism of Action
Paracetamol
Paracetamol, or acetaminophen, is a pain reliever and fever reducer that works by blocking pain signals in the brain. It is not classified as a non-steroidal anti-inflammatory drug (NSAID), making it a suitable option for those with sensitivity to NSAIDs.
Mefenamic Acid
Mefenamic acid, an NSAID, inhibits the production of prostaglandins, reducing inflammation, pain, and fever. It is particularly effective in conditions involving inflammation, such as menstrual cramps and arthritis.
Ibuprofen
Ibuprofen is another NSAID that works by blocking the production of prostaglandins. In addition to reducing pain and fever, ibuprofen has anti-inflammatory properties, making it effective for various conditions, including headaches, muscle aches, and joint pain.
Indications
Paracetamol
Recommended for general pain relief and reducing fever, paracetamol is often used for headaches, muscle aches, and mild to moderate pain. It is gentle on the stomach and suitable for those with gastric issues.
Mefenamic Acid
Specifically indicated for conditions involving inflammation, mefenamic acid is effective for managing pain associated with inflammation, such as menstrual cramps, dental pain, and certain types of arthritis.
Ibuprofen
Ibuprofen is versatile and can be used for a wide range of conditions, including headaches, muscle aches, joint pain, and inflammation. It is particularly well-suited for conditions where inflammation is a contributing factor.
Side Effects
Paracetamol:
Excessive use of paracetamol can lead to liver damage. It is crucial to adhere to recommended doses and avoid overdosing.
Mefenamic Acid:
Mefenamic acid may cause gastrointestinal side effects such as stomach pain and indigestion. Long-term use or high doses can increase the risk of more severe issues like ulcers or bleeding.
Ibuprofen:
Like other NSAIDs, ibuprofen can cause gastrointestinal issues, including stomach pain and the risk of ulcers or bleeding. It may also affect kidney function, so caution is advised in individuals with pre-existing kidney conditions.
Use During Pregnancy and Breastfeeding
Paracetamol:
Generally considered a safer option during pregnancy and breastfeeding, paracetamol is well-tolerated when used as directed.
Mefenamic Acid:
Not recommended during the third trimester of pregnancy due to potential risks to the unborn baby. Caution is advised during breastfeeding.
Ibuprofen:
Ibuprofen is generally not recommended during the third trimester of pregnancy and should be used with caution during breastfeeding. Consultation with a healthcare professional is advisable in these situations.

Mefenamic acid is used to relieve mild to moderate pain, including menstrual pain (pain that happens before or during a menstrual period). Mefenamic acid is in a class of medications called NSAIDs. It works by stopping the body's production of a substance that causes pain, fever, and inflammation. (MedlinePlus)

Ideally, pregnant women shouldn’t take ibuprofen unless a doctor recommends it. But ibuprofen appears in breast milk in small amounts, so it’s unlikely to cause any harm to your baby while you’re breastfeeding. (Scotland’s national health information service)
In conclusion, paracetamol, mefenamic acid, and ibuprofen are valuable medications for pain relief and fever reduction, each with its unique characteristics. It is crucial to use these medications responsibly, following recommended dosages and guidelines.
