Indications
Chondroitin Sulphate Sodium is a supplement used to support joint health, mainly in osteoarthritis (wear and tear arthritis) of the knee, hip and hand. It is often combined with Glucosamine. It may help ease joint pain and stiffness in some people, although results in studies have been mixed.
How It Works
Chondroitin is a natural building block of cartilage, the smooth tissue that cushions the ends of bones in a joint. Taken as a supplement, it is thought to help cartilage hold water and stay elastic, reduce the activity of enzymes that break cartilage down, and have a mild anti-inflammatory effect. Benefits, if any, usually appear slowly over several weeks to months.
Dosage and Administration
A usual adult amount is 800 mg to 1,200 mg a day, taken once daily or in divided doses, or as directed on the label or by your doctor. Take with water, preferably with food to reduce stomach upset. Allow 2 to 3 months to judge whether it helps; if there is no benefit after this time, discuss stopping with your doctor.
Interactions
Chondroitin may slightly increase the effect of blood thinners such as Warfarin, raising the risk of bleeding; your doctor may check your INR more often. Take care when combining with Aspirin, Clopidogrel or other antiplatelet medicines. Tell your doctor about any other supplements you take.
Contraindications
Do not use if you are allergic to Chondroitin or any ingredient. Products made from shellfish or animal cartilage may not be suitable for people with related allergies or dietary restrictions; check the label.
Side Effects
Chondroitin is usually well tolerated. Possible side effects include mild stomach pain, nausea, diarrhoea or constipation, bloating, headache, swelling of the eyelids or legs, and hair loss (rare).
Get urgent medical help if you develop a rash with swelling of the face or throat, difficulty breathing, or unusual bleeding or bruising, especially if you also take a blood thinner.
Pregnancy and Lactation
There is not enough information on safety in pregnancy or breastfeeding. It is best avoided unless a doctor advises it.
Precautions and Warnings
Supplements are not a substitute for medical care of arthritis; keep active and follow your doctor’s advice on weight, exercise and pain relief. People with asthma, bleeding disorders or prostate cancer should talk to a doctor before use. Combination products may contain other ingredients with their own cautions.
Overdose
Large amounts are unlikely to cause serious harm but may cause stomach upset. If a large amount is taken, or a child swallows tablets, seek medical advice.
Therapeutic Class
Joint supplement; glycosaminoglycan (symptomatic slow-acting drug for osteoarthritis).
