Hi, everyone. As of today, I've increased my dosage of Lamictal by 25mg, and am currently taking a total of 100mg. I was taking 7.5-300mg of Vicodin/Acetaminophen for a back injury, but cutting the pills in half and only taking half at a time. I'm a little nervous to continue taking the Vicodin, but I'm in a lot of pain. I don't know if these drugs have hazardous interactions. I also took 1mg of my anxiety medicine, Lorazepam, but that was hours ago. What do you all think? Will anything happen if I take a half of a Vicodin after just upping my dose of Lamictal?
