Can I take hydroxycut while on enbrel (etanercept)?

Yes! You can, but "hydroxycut" is a scam. Don't waste your money. This is not a worthwhile nutritional support for sporting activities!
Be Cautious!! Because hydroxycut is a "dietary supplement, " it hasn't undergone fda testing to assure patient safety (or effectiveness). Some of these products were recalled in 2009 after reports of associated liver problems. The interaction of this, and other potent arthritic-specific drugs (especially when given intravenously) , may be problematic and ill-advised. Speak with your pcp.
