Here is a complete, practical guide to Zerodol (Aceclofenac) for joint pain:
Zerodol (Aceclofenac) - Complete Overview
What is Zerodol?
Zerodol is a brand name for Aceclofenac, an oral NSAID (non-steroidal anti-inflammatory drug). It is widely used in India, Korea, and other countries. It belongs to the same drug class as diclofenac and ibuprofen.
Common Zerodol formulations available:
| Product | Contents |
|---|
| Zerodol | Aceclofenac 100 mg |
| Zerodol-P | Aceclofenac 100 mg + Paracetamol 500 mg |
| Zerodol-SP | Aceclofenac 100 mg + Paracetamol 500 mg + Serratiopeptidase 15 mg |
| Zerodol-TH | Aceclofenac 100 mg + Thiocolchicoside (muscle relaxant) |
How Does It Work?
Aceclofenac inhibits cyclooxygenase (COX), the enzyme that produces prostaglandins - chemical mediators that cause pain, swelling, and inflammation in joints. By blocking this enzyme, it:
- Reduces joint pain and tenderness
- Decreases swelling and stiffness
- Lowers fever if present
It acts both centrally and peripherally, making it effective for inflammatory joint conditions.
Joint Conditions It Is Used For
- Osteoarthritis (knee, hip, hand)
- Rheumatoid arthritis
- Ankylosing spondylitis (spine inflammation)
- Low back pain
- Periarthritis (shoulder pain)
- General musculoskeletal pain and sprains
A 2021 review in Journal of Pain Research (PMID: 34876850) confirmed that aceclofenac is at least as effective as other NSAIDs in reducing pain and improving functional capacity in osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and low back pain.
Typical Dosage
- Standard dose: 100 mg twice daily (morning and evening), with food
- Zerodol-P / SP: 1 tablet twice or three times daily as prescribed
- Duration: Short courses (5-10 days) for acute pain; longer-term use only under medical supervision
Side Effects to Know
| System | Side Effects |
|---|
| Gastrointestinal (most common) | Acidity, nausea, stomach pain, peptic ulcers, GI bleeding |
| Kidneys | Reduced kidney function with prolonged use |
| Cardiovascular | Increased risk of heart attack/stroke with long-term use |
| Liver | Elevated liver enzymes (rare) |
| Allergic | Skin rash, rarely severe reactions |
Aceclofenac has a better GI safety profile than older NSAIDs like indomethacin or piroxicam, but GI precautions still apply.

Who Should NOT Take Zerodol
- Active peptic ulcer or GI bleeding
- Severe heart failure or kidney/liver disease
- Known allergy to NSAIDs or aspirin
- Pregnancy (especially third trimester)
- Children under 18 (not recommended)
- People on blood thinners (warfarin, aspirin) - increased bleeding risk
Important Practical Tips
- Always take with food or milk to protect the stomach
- Do not take on an empty stomach - this is the most common cause of NSAID-related stomach problems
- If you have a history of acidity or ulcers, your doctor may prescribe a proton pump inhibitor (e.g., Pantoprazole/Omeprazole) along with it
- Do not self-medicate for more than 3-5 days without consulting a doctor
- Avoid combining with other NSAIDs (e.g., ibuprofen) simultaneously
When to See a Doctor
- Joint pain lasting more than 2 weeks
- Significant swelling, warmth, or redness of a joint
- Morning stiffness lasting more than 1 hour (may suggest rheumatoid arthritis)
- Pain not responding to Zerodol
- Any stomach pain, black stools, or blood in urine after starting the medicine
Bottom line: Zerodol (Aceclofenac) is a well-established, effective NSAID for joint pain conditions. It works well for short-term relief of osteoarthritis, back pain, and inflammatory arthritis. Take it with food, use the minimum effective dose for the shortest duration needed, and consult a doctor if pain is persistent or severe.
