some time according to the American Heartworm Society. The letter from Merial has been sent to vets. When the product supply is depleted, there will be no more to be had for I don't know how long. Doesn't sound good at all.

Please keep your pups on heartworm prevention year-round.

Treatment for now will vary by vet and probably include doxycycline and a monthly preventative which is what some refer to as slow kill. It's thought to be way less desirable than Immiticide therapy in most cases.
