Drug screen question?

April of 2009 I got my first outbreak of cold sores. They spread ALL over my top and bottom lips, it was the grossest thing I'd ever seen and I didn't leave the house for literally a week and a half (thank you, spring break). I was still living at home, and my mom had a routine dr appt and while she was there she told the dr about how bad it was, and he said he gives his daughter acyclovir tablets for cold sores, and wrote my mom a script in her name, with the intentions of me taking the medication. Well, they cleared up quickly, and ever since then he's been approving refills, and I take one 800 mg pill when I feel one starting to pop up, which is about once every 2-3 weeks. I start my first year of NS in a week and not too sure what all they screen for. I know I need to go to the dr and get the script in my own name, but will an antiviral show up on the test? Thanks!
