Isoniazid
"I've been on the isoniazid for almost one month and I'm not sure I will be able to continue. I'm experiencing bad headaches nearly every day. Before going on the drug, I took Tylenol every 6 hours for arthritis pain. Now I have had to stop the tylenol. I have Crohn's disease so I can't take any NSAIDS. That leaves me no options for my headaches. Not sure I can deal with this for 9months. After one week my liver enzymes have already increased by 7. Pretty stressed out about this whole thing. I tested positive for latent TB when waiting to start Humira for my Rheumatoid Arthritis. Now I can't take anything for my pain until I'm treated for the TB for 9months. Life sucks."
