Using medications such as barbiturates, St. John's wort, or Topamax, could decrease the level of ella in your blood, possibly making this emergency contraceptive less effective. However, women are not usually advised to stop taking any drug just because of a possible interaction with ella. There is typically no need to stop any other medication, as ella is only taken as a single dose.

More Detail on Ella Drug InteractionsAll of the medications listed above could theoretically decrease the level of ella in your blood, possibly increasing the chance of becoming pregnant.
Women are not typically advised to stop taking any medication just because of a possible drug interaction with ella. Most of the medications that may, theoretically, interact with ella do so because they cause the liver to break down (metabolize) ella too quickly. Stopping these medications temporarily is not likely to help much, as the liver will not adjust right away.
However, if you have any concerns about possible drug interactions, you should not hesitate to contact your healthcare provider.
