Hello. I am currently on Doryx for acne and I am getting a surgical procedure done in 2 weeks septorhinoplasty and they have written me perscriptions for: Cephalexin 500mg Phenergan 25mg Vicoden Valium My question, is do I need to stop taking my acne (Doryx) prior to surgery and if so, how soon before? It s an antiobiotic, so I am suppose to finish it. If I stop before the surgery, how soon after surgery can I start them back up. I m sure I will be taking the others for 2 weeks or so after surgery. Thoughts? thanks!
