Having to take an emergency contraceptive isn’t exactly fun, but finding out it's a fake would be a lot worse. The FDA says a morning-after pill called Evital might be counterfeit and may not prevent pregnancy. It’s not approved for use in the U.S. and the FDA is asking women who have taken it and are having side effects to call their doctors.

A CNN health blog, The Chart, reports that “the FDA says, while it doesn't have evidence of "pattern targeting" of a specific ethnic group, the drug may have been distributed in Hispanic communities under the label “Evital Anticonceptivo de emergencia, 1.5mg, 1 tablet by Fluter Domull.” They’re also asking that anyone with information on Evital contact the Center for Drug Evaluation and Research/Ingredient Adulteration.

The Chart also lists some of the more common brands of emergency contraceptives: Plan B One-Step, Next Choice and ella, which are available over-the-counter if you’re 17 or older or with a prescription.

So spread the word, and check the box! The last thing you want in an emergency is an emergency.
