I take a brand named Apri 28 as my birth control measure however as I just got my wisdom teeth out yesterday I do have one concern. I am currently on my Placebo pills, will the medications I was prescribed (and taking as told) affect the effectiveness of my next package of pills. If need be, these are the prescriptions the Oral Surgeon gave me: -Apo-Amoxi 500 MG amoxicillin trihydrate -pms-dexamethasone 4 MG dexammethasone -ratio-lenoltec no.3 30 MG codeine/acetaminophen cafeine Thank you, Sarah
