Lupin Pharmaceuticals, the New Jersey-based company that produces birth control pill Tydemy, is recalling two batches of the drug because they may have reduced effectiveness.
According to Lupin, the batches are being recalled because tests showed the pills had decreased levels of ascorbic acid, an inactive ingredient, and high levels of a “known impurity.”
The company said the low levels of ascorbic acid “could potentially impact the effectiveness of the product which could potentially result in unexpected pregnancy.”
