A member asked:

I was on antibiotics (z pack) the 1st wk of period. i am also on orthotricyclen. will my bc still be effective? i'm taking the second week now.

A doctor has provided 1 answer

Unlikely interference: it is highly unlikely that the Z pack that you took will interfere with the effectiveness of the ortho Tri-Cyclen, especially since you took it why you were on your menstrual period which is when you are taking the pills that have no Hormones in them.
