How Diclofenac Sodium Works

Diclofenac sodium blocks enzymes called cyclooxygenase (COX-1 and COX-2). These enzymes help produce prostaglandins, hormone-like molecules that trigger pain, inflammation and fever. By reducing prostaglandin levels, diclofenac:

• Eases pain
• Lowers swelling
• Brings down fever (less commonly used for this)

Oral Tablets: Common Uses

1. Arthritis

• Osteoarthritis – Pain and stiffness in weight-bearing joints (knees, hips).
• Rheumatoid arthritis – Chronic joint inflammation caused by an autoimmune reaction.
• Ankylosing spondylitis – Inflammation of spinal joints leading to stiffness and pain.

2. Acute Pain

• Musculoskeletal injuries – Sprains, strains, pulled muscles.
• Postoperative pain – Pain after surgery, often given for short-term relief.

3. Dysmenorrhea

• Menstrual cramps – Reduces painful uterine contractions in primary dysmenorrhea.

4. Migraine

• Acute migraine attacks – Certain formulations (e.g., Diclofenac potassium) are FDA-approved for fast relief.

• Localized musculoskeletal pain – Sprains, strains, tendonitis, bursitis.
• Minor sports injuries – Reducing swelling and speeding recovery.

Precautions and Who Should Be Careful

• History of ulcers or GI bleeding: Higher risk of life-threatening gastrointestinal effects.
• Heart disease or stroke: NSAIDs can worsen heart failure and raise clot risk.
• Kidney or liver impairment: May need dose adjustments or avoid use.
• Pregnancy and breastfeeding: Generally avoid, especially in the third trimester.
• Allergy to NSAIDs: Risk of severe allergic reactions, including asthma flare-ups.

---

Drug Interactions

Diclofenac can interact with other medications, increasing risks:

• Anticoagulants (e.g., warfarin) – Greater bleeding risk.
• Other NSAIDs/aspirin – More gastrointestinal toxicity.
• Blood pressure drugs (ACE inhibitors, diuretics) – Reduced effectiveness or kidney damage.
• Lithium, methotrexate – Higher blood levels and toxicity.

Always inform your doctor or pharmacist about all prescription drugs, over-the-counter medicines, vitamins and supplements you take.

Tips for Safe Use

• Always take the lowest effective dose for the shortest possible time.
• For tablets, take with meals or a glass of milk to lower stomach upset.
• For gel, wash hands before and after application (unless treating your hands).
• Avoid applying near eyes, mouth or open wounds.
• Store at room temperature, away from heat and moisture.

When to Seek Medical Advice

Diclofenac sodium can be a very effective tool for managing pain and inflammation, but it’s not risk-free. If your pain persists, worsens or is accompanied by:

• High fever
• Unexplained weight loss
• Severe swelling
• Neurological symptoms (numbness, tingling, weakness)

…talk to your doctor. For non-urgent concerns or to clarify your symptoms, you might consider a free, online symptom check, using the doctor approved Ubie Symptom Checker.

Summary

Diclofenac sodium (tablet and gel) is widely used to treat arthritis, acute musculoskeletal pain, menstrual cramps and migraines. It works by blocking COX enzymes to reduce prostaglandins, easing pain and inflammation. While generally well tolerated, it carries risks—particularly for the stomach, heart, kidneys and liver. Always follow dosing instructions, watch for side effects and discuss your full medical history with a healthcare professional before starting or stopping diclofenac.
