Drug maker Allergan reports that hormone pills and placebos were placed in consumer packages in the wrong order. Taking the pills in the wrong order can result in unintended pregnancy. The company is urging users to return their Taytulla pills.

According to Allergan:

As a result of this packaging error, oral contraceptive capsules, that are taken out of sequence, may place the user at risk for contraceptive failure and unintended pregnancy. The reversing of the order may not be apparent to either new users or previous users of the product, increasing the likelihood of taking the capsules out of order. If patients have concerns regarding the possibility of an unintended pregnancy they should consult their physician.
