Terramycin eye ointment for cats and dogs, which has been off the U.S. market for at least 16 months, is not expected to be available for another eight months, a spokesman for the manufacturer said Oct. 14.
“Zoetis continues working with an external supplier and appropriate regulatory agencies to address the interruption of supply for Terramycin Ophthalmic Ointment,” company spokesman Deron Johnson told Examiner.com. “We had expected to receive final regulatory approval of our plan to supply the market by the end of this year, but we continue to experience delays in the process. The current estimate for product availability is now June 2014, pending the resolution of regulatory approvals and certain supply issues.
Zoetis, formerly Pfizer Animal Health, first indicated in June 2012 that it was experiencing a “temporary interruption of supply” that could continue through the end of 2012. The company later said it expected the shortages to continue until the second or third quarter of 2013. The latest delay would extend the drug’s time off the market to two years.
The company has given no reason for what caused the supply interruption. Some consumers have gotten around the disruption by ordering foreign-labeled Terramycin online, but it is unclear whether those products receive the same amount of government oversight as ointment intended for the U.S. market.
Terramycin is an antibiotic designed to treat mild bacterial eye infections.
