The most common side effects include itchiness and a skin rash.[4] Other side effects may include dizziness, hives, anaphylaxis, hearing loss, and headache.[2][4] Safety in pregnancy and breastfeeding is unclear.[5] The antibiotics work by killing specific types of bacteria while the steroids work by decreasing inflammation.[6]

The combination was approved for medical use in the United States in 1964.[3] In 2019, it was the 329th most commonly prescribed medication in the United States, with more than nine hundred thousand prescriptions.[7]

History

Cortisporin was developed by Glaxo Wellcome and was approved by the US Food and Drug Administration in 1975. In 1997, the rights were sold to Monarch Pharmaceuticals, a division of King Pharmaceuticals. In 2007, King sold it to JHP Pharmaceuticals. Par Pharmaceutical acquired JHP in 2014. In 2015, Endo International purchased Par.[8]
