Merial Runs Out of Immiticide for Heartworm Treatment
Heres what owners of heartworm-positive dogs can do until the only approved heartworm treatment is available again.
The supply of Immiticide (melarsomine dihydrochloride), the only drug approved to treat heartworm infections in dogs, has been low since December 2009, but now its completely gone. Merial confirmed that it was officially out of the drug on August 9, 2011. The current situation is due to a new and separate manufacturing challenge related to technical issues with the company who provides the finished product, according to a Merial spokesperson. Merial said the company is working hard to make the drug available again, but cannot speculate when that might happen.
