Understanding Pain Relievers: The Big Difference
Pakistan's OTC pain relief market is dominated by two drug classes:
- Paracetamol (acetaminophen): Sold as Panadol, Panadol Extra, Panadol CF, and generic paracetamol.
- Ibuprofen (NSAID): Sold as Brufen, Advil, and generic ibuprofen.
These are not interchangeable — they work through completely different mechanisms and are appropriate for different types of pain and different patients.
Paracetamol (Panadol): How It Works
Paracetamol acts centrally in the brain to raise the pain threshold and reduce fever. It does not reduce inflammation at the site of injury.
Best for:
- Headaches and migraines
- Fever reduction
- Cold and flu symptoms
- General aches and fatigue
- Post-vaccination discomfort
- Pain during pregnancy (under medical guidance)
- Patients with kidney disease, stomach ulcers, or heart disease (where NSAIDs are contraindicated)
Standard adult dose: 500–1,000mg every 4–6 hours. Maximum 4,000mg (4g) per day.
Key safety warning: Paracetamol is the leading cause of acute liver failure worldwide — not because it is inherently dangerous, but because people underestimate how much they take. Never exceed 4g/day. Never combine with alcohol. Be aware of paracetamol hidden in combination products (Panadol CF, Panadol Cold & Flu, Panadol Night, etc.) — these count toward your daily total.
Ibuprofen (Brufen / Advil): How It Works
Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID). It blocks cyclooxygenase (COX-1 and COX-2) enzymes that produce prostaglandins — the chemicals responsible for inflammation, pain, and fever.
Best for:
- Muscle pain and sports injuries
- Arthritis and joint inflammation
- Dental pain and toothache
- Dysmenorrhea (menstrual cramps)
- Back pain with an inflammatory component
- Fever (especially when inflammation is the cause)
- Gout attacks
Standard adult dose: 200–400mg every 4–6 hours. Maximum 1,200mg/day OTC (up to 3,200mg/day under prescription supervision).
Key safety warnings:
- Take with food — ibuprofen directly irritates the stomach lining. Never take on an empty stomach.
- Avoid or use with extreme caution in patients with peptic ulcer disease, kidney disease, heart failure, or hypertension.
- Avoid in the third trimester of pregnancy — NSAIDs can cause premature closure of the ductus arteriosus.
- Do not combine with blood thinners (warfarin, aspirin) without medical supervision.
Panadol Extra: What's Different?
Panadol Extra contains paracetamol 500mg + caffeine 65mg per tablet. The caffeine is an analgesic adjuvant — it enhances the effectiveness of paracetamol by approximately 40% for headache and migraine. It is not a stronger dose of paracetamol — it is the same dose working more effectively due to the caffeine boost. Best suited for headaches, migraines, and tension headaches. Not recommended at night due to caffeine content.
Panadol CF: What's Different?
Panadol CF (Cold & Flu) combines paracetamol 500mg + phenylephrine 5mg (decongestant) + caffeine 25mg. It is specifically formulated for cold and flu where nasal congestion, fever, and headache are all present simultaneously. Critical warning: Do not combine with any other paracetamol products — this will exceed the safe daily paracetamol limit.
Quick Comparison
| Factor | Panadol (Paracetamol) | Brufen/Advil (Ibuprofen) |
|---|---|---|
| Reduces inflammation | No | Yes |
| Reduces fever | Yes | Yes |
| Safe in pregnancy | Yes (T1/T2 only, with advice) | T1/T2 with caution only; AVOID T3 |
| Safe with ulcers | Yes | No — use with great caution |
| Safe with kidney disease | Yes (low doses) | Avoid |
| Heart disease risk | Low | Increases with long-term use |
| Liver risk | Yes if overdosed | Low at recommended doses |
| Take with food | Optional | Always required |
Can You Take Paracetamol and Ibuprofen Together?
Yes — they work via different mechanisms and can be safely combined or alternated under appropriate medical conditions. Some protocols for moderate pain alternate them every 3–4 hours to provide continuous coverage. However, always consult a doctor or pharmacist before combining them, as the underlying condition should guide the choice.
When to See a Doctor
OTC pain relief should not mask serious underlying conditions. Seek medical attention if:
- Pain is severe, sudden, or the worst you've ever experienced
- Fever exceeds 40°C or persists beyond 3 days in adults
- Pain is accompanied by chest tightness, shortness of breath, or arm/jaw pain
- You require pain relievers daily for more than 10 days
- A child under 6 requires pain relief — always consult a pediatrician first
