i was recently tested positive to be a carrier of tuberculosis and i have to take a medicine called isoniazid. i am currently using hydroxycut which contains ephedrine. since both are very stressful to your internal organs, especially the liver, i was wondering if anyone knew whether or not it would be harmful.

I take Hydroxicut occassionally. I do not know about the other drug you are talking about, but I know that I have to be extremely careful when taking anything the same day I took Hydroxicut. Even cold or sinus medicine screws with me because it contains pseudoephedra so I'm getting a double dose of the drug, which makes my heart feel like it's going to beat out of my chest. I found this out the hard way. Just be extremely careful when taking this product. As it is good for weight loss and increased energy to work out, it is potentially harmful, so please check with your doctor to find out what's in isoniazid. If it has any other stimulants in it, it could be a bad combination.
