I was on Qsymia for about a year with no issues, and then I got pregnant while on the pill. I've been on the pill for like 10 years and never had this issue. I opted to take the abortion pill and then a few months later I got pregnant again (I took the birth control pill exactly as prescribed along with Qsymia). This time, the pregnancy ended up in an early miscarriage on its own. I read online that anti-seizure medications (the topirimate in Qsymia) can cause the estrogen in birth control to be less effective. Has anyone else had this issue?
