Allergan plc, a leading global pharmaceutical company, and Medicines360, a nonprofit women's health pharmaceutical company with a mission of expanding access to quality medicines, announced that they will donate 10,000 units of their hormonal IUD, Liletta (levonorgestrel-releasing intrauterine system) 52 mg, to the CDC Foundation. In addition, Allergan will donate over 40,000 one-month cycle packs of oral contraceptives. The contributions are in response to the outbreak of the Zika virus and are designed to help reduce unintended pregnancies in Puerto Rico, while the risk of the Zika virus is prevalent. Research has shown that pregnant women infected with the Zika virus are at risk of giving birth to infants born with microcephaly, a condition where babies' heads and brains are smaller and may not have developed properly during pregnancy.
