Osteoguard is a brand name for various health supplements, but a critical distinction exists between different products under this name. Some formulations, like 'Osteoguard Tablet 10' or 'Ostogard GM,' are prescribed for osteoarthritis and contain glucosamine, diacerein, and MSM. Other supplements, like those from Lamberts, are dietary bone formulas containing calcium, magnesium, and vitamins D and K. The contraindications vary significantly based on the specific formulation, highlighting the importance of understanding the ingredients before use.
Serious medical conditions and pre-existing risks
Kidney and liver disease
Individuals with severe kidney or liver disease should generally avoid Osteoguard. For supplements containing glucosamine and diacerein, severe renal impairment is a contraindication, as the medicine is excreted through the kidneys. Severe liver disease also warrants avoiding these formulations due to potential interactions with other medications. For calcium and vitamin D-based Osteoguard, kidney disease patients must be cautious, as their ability to regulate calcium and phosphorus can be impaired. High calcium intake can worsen kidney problems and lead to calcification.
Pregnancy and breastfeeding
Most Osteoguard formulations are not advised during pregnancy or breastfeeding due to a lack of sufficient safety data. Glucosamine-based products, in particular, are not recommended for use in pregnancy as they may harm the fetus. Pregnant and lactating women should consult their doctor before taking any supplement, including Osteoguard. A rare exception mentioned for a calcium/magnesium-based Osteoguard product by one manufacturer suggests suitability, but only with a doctor's advice.
Allergies and sensitivities
Those with shellfish allergies should avoid glucosamine-containing Osteoguard, as the ingredient is often derived from shellfish. Additionally, other components in some formulations, like certain inactive ingredients, can cause allergic reactions. Individuals with known allergies to any ingredients should not take the product.
Diabetes and glaucoma
Glucosamine can affect insulin sensitivity and increase blood sugar levels, making it potentially risky for people with type 2 diabetes. Careful blood sugar monitoring is required. The presence of glucosamine in some Osteoguard formulations may also increase intraocular pressure, posing a risk for patients with glaucoma or a history of ocular hypertension.
Irritable bowel syndrome
For Osteoguard products containing diacerein, caution is advised for people with Irritable Bowel Syndrome (IBS). Diacerein can cause diarrhea and may worsen the condition.
Important drug interactions
Osteoguard can interact with a range of medications, making medical consultation essential. The following are key examples:
- Anticoagulants (e.g., Warfarin): Glucosamine and Vitamin K, found in different Osteoguard formulations, can interact with blood thinners like warfarin, significantly increasing the risk of bleeding.
- Diuretics: The diacerein in some formulations can amplify the dehydrating effects of diuretics like furosemide. Similarly, calcium and vitamin D supplements should be used cautiously with thiazide diuretics, as they can cause overly high calcium levels in the blood.
- Hypoglycaemic Agents: Diacerein, combined with anti-diabetic medicines, can enhance their effects, necessitating careful blood sugar monitoring.
- Cholesterol-lowering statins: High-dose vitamin D supplements might reduce the effectiveness of statins.
- Other supplements: Combining certain supplements, like glucosamine and acetaminophen, may reduce the effectiveness of both.

Is Osteoguard suitable for children?
Based on safety and efficacy data, Osteoguard supplements containing glucosamine and diacerein are not recommended for children under 18 years of age. For all formulations, it is crucial to consult a doctor before administering any medication or supplement to a child.
The critical role of medical consultation
Given the wide range of potential risks and drug interactions, consulting a healthcare professional is non-negotiable before starting Osteoguard. An individualized assessment is essential, especially for those with pre-existing conditions or taking other medications. A doctor can recommend the safest product and dosage or suggest alternative treatments. The Mayo Clinic provides further information on glucosamine safety that may be relevant to glucosamine-containing Osteoguard products.
Conclusion
Understanding who should not take Osteoguard is vital for patient safety, given the different formulations and associated risks. Contraindications range from severe liver and kidney diseases to pregnancy, breastfeeding, and specific allergies. Drug interactions, particularly with blood thinners like warfarin and diabetic medications, also pose significant risks. Always consult a healthcare professional for a comprehensive evaluation of your health status and medication history before using any Osteoguard product. Never self-prescribe, and be aware of the specific ingredients in the product you are considering.
