Osteoarthritis (OA) is a common condition affecting millions worldwide. It's characterized by the breakdown of cartilage in joints, leading to pain, stiffness, and reduced mobility. While there's no cure, many over-the-counter (OTC) treatments can help manage symptoms effectively.
Here's a quick guide to common OTC options for OA:
1. Pain Relievers (Analgesics):
Paracetamol :
How it works: Reduces pain perception.
Dosage: Typically 500mg - 1000mg every 4-6 hours as needed. Maximum daily dose is usually 4000mg.
Contraindications: Severe liver disease. Caution with chronic alcohol use.
Brand examples (Australia): Panadol, , Chemist's Own Paracetamol.
2. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs):
How they work: Reduce both pain and inflammation.
Oral NSAIDs:
Ibuprofen:
Dosage: 200mg - 400mg every 4-6 hours as needed. Maximum daily dose usually 1200mg (OTC).
Contraindications: History of stomach ulcers/bleeding, severe kidney disease, heart failure, asthma (NSAID-induced), late pregnancy.
Brand examples (Australia): Nurofen, Advil, Brufen.
Naproxen:
Dosage: 250mg - 500mg twice daily. Maximum daily dose usually 1000mg (OTC).
Contraindications: Similar to ibuprofen (stomach ulcers/bleeding, severe kidney disease, heart failure, asthma, late pregnancy).
Brand examples (Australia): Naprogesic (note: often marketed for period pain but same drug), Aleve.
Topical NSAIDs (creams/gels applied to the skin):
Diclofenac gel:
How it works: Localized pain and inflammation relief with less systemic absorption than oral NSAIDs.
Dosage: Apply 2-4 grams to the affected joint 3-4 times daily.
Contraindications: Open wounds, dermatitis, and caution with severe kidney/liver disease, and late pregnancy.
Brand examples (Australia): Voltaren Emulgel, Fenac.
Important Considerations:
Always read the label: Follow dosage instructions carefully.
Side effects: All medications can have side effects. NSAIDs, especially oral ones, can cause stomach upset, and long-term use can increase the risk of cardiovascular issues.
Consult your doctor or pharmacist: Before starting any new medication, especially if you have existing health conditions or are taking other medications. They can help determine the best and safest treatment plan for you.
Lifestyle: Regular, gentle exercise, maintaining a healthy weight, and heat/cold therapy can also significantly help manage OA symptoms.
