When it comes to managing acute pain, two popular over-the-counter options are naproxen and ibuprofen. I aim to help you understand the differences between these two medications, their effectiveness, and how to use them safely.
In this article, we’ll compare and contrast naproxen and ibuprofen, discuss their histories, benefits and drawbacks, onset of action, side effects, and available forms.
Naproxen vs. ibuprofen: how they work
Both naproxen and ibuprofen belong to the class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). They are effective for relieving pain, reducing inflammation, and lowering fevers. Here’s a breakdown of how each works:
Mechanisms of action
Naproxen:
- Inhibits cyclooxygenase (COX-1 and COX-2) enzymes.
- Reduces production of prostaglandins, which are chemicals that promote inflammation and pain.
Ibuprofen:
- Also inhibits COX-1 and COX-2 enzymes.
- Works similarly to naproxen by decreasing prostaglandin levels, thereby alleviating pain and inflammation.
Summary of comparison
- Mechanism: Both inhibit COX enzymes, reducing pain-causing prostaglandins.
- Duration: Naproxen generally lasts longer (up to 12 hours) compared to ibuprofen (4-8 hours).
History of naproxen and ibuprofen
Naproxen
- Introduced: In the 1970s, initially marketed under the brand name Naprosyn.
- Use: Gained popularity for its effectiveness in treating arthritis, menstrual pain, and other inflammatory conditions.
Ibuprofen
- Introduced: Developed in the 1960s and approved for medical use in the UK.
- Use: Widely recognised for its effectiveness in treating a variety of pain types, including headaches, toothaches, and muscle pain.
Pros and cons of naproxen vs. ibuprofen
| Naproxen | Ibuprofen |
| Longer duration of action (up to 12 hours) Effective for chronic pain management May have a higher risk of gastrointestinal side effects Not recommended for long-term use without medical supervision | Shorter onset of action, making it suitable for quick relief Generally well-tolerated and widely used Requires more frequent dosing due to shorter duration (4-8 hours). May not be as effective for chronic pain conditions compared to naproxen |
In general, both medications offer relatively quick relief, with noticeable effects within 30 minutes to 1 hour.
Side effects of naproxen and ibuprofen
Both medications can cause side effects, although they can vary in severity and occurrence.
Common side effects
Naproxen:
- Gastrointestinal issues (nausea, heartburn, stomach pain)
- Drowsiness or dizziness
- Increased risk of bleeding
Ibuprofen:
- Gastrointestinal disturbances (nausea, vomiting, diarrhoea)
- Headaches or dizziness
- Rashes or allergic reactions
Rare but serious side effects
- Naproxen: Liver or kidney damage, serious allergic reactions.
- Ibuprofen: Risk of cardiovascular events with long-term use, kidney damage.
Summary of side effects
- Naproxen: Higher risk of gastrointestinal issues, potential for liver/kidney damage.
- Ibuprofen: Common gastrointestinal issues, risk of cardiovascular events with prolonged use.
Available forms and how to take them
Both naproxen and ibuprofen are available in various forms, including:
- Tablets: Standard oral form.
- Liquid Suspensions: Useful for children or those who have difficulty swallowing pills.
- Topical Gels: Applied directly to the skin for localised pain relief (more common with ibuprofen).
