Glucosamine Drug Interactions

Theoretically, glucosamine might enhance the ability of cancer cells to resist chemotherapy medications. If you are undergoing chemotherapy treatment, be sure to check with your oncologist before taking glucosamine.

 

In theory, glucosamine may decrease insulin production or increase the body's resistance to the effects of insulin. Both of these actions could result in high blood sugar (hyperglycemia). However, studies generally show that this is probably not a problem for most people. It might be a good idea to check your blood sugar more often when starting or stopping glucosamine, just to be sure.

 

There have been cases of increased international normalized ratio (INR, a laboratory test that measures blood coagulation) in people taking glucosamine with warfarin. This means that combining the two might increase the risk of bleeding, including dangerous internal bleeding. If you take warfarin, check with your healthcare provider before starting or stopping glucosamine, as you may need to be monitored more closely.
