Interactions with Drugs
In theory, chondroitin may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants ("blood thinners") such as warfarin (Coumadin®) or heparin, anti-platelet drugs such as clopidogrel (Plavix®), and non-steroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).
Use cautiously with hyaluronidase or agents with hydrophilic (attraction to water) properties. Consult with a qualified healthcare professional, including a pharmacist, to check for interactions.
Also use cautiously when combining chondroitin with other agents that may cause sun sensitivity, as chondroitin may increase sun sensitivity.
Interactions with Herbs and Dietary Supplements
In theory, chondroitin may increase the risk of bleeding when taken with herbs and supplements that are believed to increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.
Based on preliminary data, chondroitin may increase iron absorption. It may also interact with or alter concentrations of calcium, camphor, glucosamine, manganese, peppermint oil, and shark cartilage.
Use cautiously with herbs or supplements with hydrophilic (attraction to water) properties. Consult with a qualified healthcare professional, including a pharmacist, to check for interactions. Also use cautiously when combining chondroitin with other agents that may cause sun sensitivity, as chondroitin may increase sun sensitivity.
