Earlier this year I found out, somewhat randomly, that veterinarians were experiencing shortages of the heartworm medications Interceptor and Sentinel. As soon as I could, I went straight to the veterinarian and bought two of their last three boxes. I was shocked that the office wasn't more proactive in informing patients about the problem.
However, it seems that veterinarians didn't have the whole story either and that this situation isn't exactly uncommon.
Back in December, Novartis closed a Lincoln, Nebraska factory that produced both veterinary and human medication, including Interceptor, Sentinel, and Excedrin. While there are alternatives available, veterinarians have been frustrated over the way Novartis handled communication. The company is still unable to provide a date for when the factory will resume production.
As I've been researching the topic, it looks like product shortages and recalls are no stranger to the veterinary field. After scrambling to buy the last boxes of Interceptor, I decided that I'm going to be proactive and research alternatives for all medication that my pets take. I found out about the Interceptor shortage through a passing comment on Facebook and was shocked that information wasn't widely shared either in the news or by my veterinarian.
The shortage comes at a particularly bad time since the mild winter has created an increased risk of heartworm disease this year. Given how long this problem has lasted so far, it's probably best to find an alternative if you're running low on medication.
Some dogs, particularly herding breeds, have an adverse reaction to heartworm medications containing ivermectin, so it's important to consult your veterinarian to identify a safe alternative.
Are you prepared if access is restricted to the medications your pets use?
