I had a prescription for trileptal which I quit taking after it gave me a rash. Got prescribed lamictal instead. Yesterday I was EXTREMELY tired when I went to pick up a prescription for an ear issue I'd been having. I took the prescription and woke up super early like I used to with the trileptal (it would make me VERY awake). That's when I realized what happened. Checked the bottle, and sure enough it wasn't the right prescription.
I threw the bottle out, but wondered if there might be any issues with having the two meds in my system.
