Here is a clear, evidence-based answer to your question:
Are Mefenamic Acid and Paracetamol Effective for Sore Throat and Headache?
Yes, both drugs work - but they differ in how well they work and in what situations each is preferred.
Paracetamol (Acetaminophen)
For sore throat:
Paracetamol works and is recommended, particularly for mild cases. According to Scott-Brown's Otorhinolaryngology, "NSAIDs and paracetamol are more effective than placebo for relief of symptoms. Paracetamol will suffice for mild cases." For adults with more severe throat pain, NSAIDs like ibuprofen are considered superior. In children, paracetamol is the first choice for sore throat.
For headache:
Paracetamol is one of the most widely used treatments for headache. As stated in Goodman & Gilman's Pharmacological Basis, it "raises the threshold to painful stimuli," and is used in "vascular headache remedies" and common analgesic combinations.
- Dose: 325-650 mg every 4-6 hours; do not exceed 4 g/day
- Advantage: Very safe, well tolerated, suitable for children and those who cannot take NSAIDs
- Weakness: Only weak anti-inflammatory effect at usual doses
Mefenamic Acid (an NSAID - Fenamate class)
For sore throat:
As an NSAID, mefenamic acid can reduce the inflammation, pain, and fever associated with sore throat. NSAIDs as a class are effective for sore throat, but ibuprofen and diclofenac are the more commonly recommended NSAIDs for this purpose. Mefenamic acid is not specifically listed in sore throat guidelines.
For headache:
Mefenamic acid has been directly compared to paracetamol for headache. A double-blind clinical trial (PMID: 6347393) showed mefenamic acid reduced headache intensity by 36% vs. 27% for paracetamol - a slightly better result, though the difference was not statistically significant. A cross-sectional study among medical students found paracetamol was used most commonly (75%) for headache self-medication.
- Dose: Typically 500 mg initially, then 250 mg every 6 hours (short-term use only)
- Advantage: Has both analgesic AND anti-inflammatory action
- Weakness: More side effects (GI upset, diarrhea), not recommended for children or pregnant women, not ideal for long-term use
Quick Comparison Table
| Feature | Paracetamol | Mefenamic Acid |
|---|---|---|
| Sore throat pain | Yes (mild-moderate) | Yes (anti-inflammatory too) |
| Headache | Yes | Yes (slightly stronger) |
| Fever reduction | Yes | Yes |
| Anti-inflammatory | Weak | Strong |
| Safe in children | Yes (first choice) | Not recommended |
| Safe in pregnancy | Preferred | Avoid |
| GI side effects | Minimal | More common |
| Liver risk (overdose) | Yes | Less |
Bottom Line
- For most people with sore throat + headache: Start with paracetamol - it is safe, effective, and has fewer side effects.
- For adults with moderate-to-severe throat inflammation and headache: An NSAID (ibuprofen is the guideline-preferred choice; mefenamic acid is also effective) provides slightly better pain and inflammation relief.
- Never exceed recommended doses of either drug, and avoid mefenamic acid in children, pregnant women, or those with kidney/GI problems.
