My Girlfriend Thinks She Is Having A Herpes Outbreak. She

My girlfriend thinks she is having a herpes outbreak. She is very uncomfortable and unfortunately waited until too late in the day to get medical attention today. I may be having a small outbreak as well; I got some acyclovir from my Dr. that is helping me but I am reluctant to share it with her because I believe it is illegal and I don't know what her dosage should be. Is there anything you can recommend to ease her discomfort (itching, pain during urination) until she can see a Dr.?
