Hi, There is no medication which can cure or prevent Chicken pox. Ampiclox is an antibiotic , something that affects bacteria & Chicken pox is a virus !! how can it help. It only reduces secondary infections after you get chicken pox. If your partner has chickenpox, better you delay attempting for pregnancy till fully healthy. When male gets infections- their sperm count, motility & health is reduced. So pregnancy chances is low. In women - Ovulation may not occur due to fever. But incidentally if you get pregnant, the virus in chicken pox & fever itself will cause certain irreparable damages in the baby. Either it will end in abortion or baby with certain defects warranting abortion. So I would advise you to wait for the infection to completely leave your house for you to try for pregnancy. Hope I have cleared your query All the best Dr.Balakrishnan
