Q: Are diet pills ok to take when I try to conceive (TTC)?

A: When you TTC, you should observe the same rules as if you were pregnant. In general, weight loss should not be attempted during pregnancy and the use of phentermine during pregnancy is not indicated. In addition, there is concern about a possible association between weight loss in early pregnancy and neural tube defects in the offspring. We suggest you let your doctor know about it and discuss what to do next.
