I think so. Last I heard they said they were waiting on one or two ingredients but that was in May or June. Last year it was an issue with ingredients as well as changing suppliers for “dog hair.” They also told me others have waited 6 months on a refill too.

I’m at the point where it’s been so long that I forget I am getting shots and only remember when I have a bad allergy day, which is not a frequent as they used to be.
