Apotex Corporation has recalled four lots of birth control pills because the tablets may have been arranged incorrectly or could be missing, the FDA announced Monday.

The packaging error could cause women to not take a table because it was missing or take an active tablet instead of placebo which could lead to an unplanned pregnancy, a recall statement said.

The pills must be taken in the correct order for them to be effective.

However, as of Monday, there have been no reports of any adverse effects or unintended pregnancies, according to the FDA.

“Individuals should not interrupt their therapy, use a non-hormonal method of birth control, contact their health care provider for medical advice and may return the impacted packages to their pharmacist,” the FDA said in a statement.

Apotex has also notified places where the pills were shipped and has arranged for them to be returned.

Anyone with questions about the recall was asked to contact Apotex at 1-800-706-5575.
