I want to know some things about Ivermectin. 1) Is it safe

Customer Question

I want to know some things about Ivermectin.
1) Is it safe in all cats/dogs?
2) sometimes we adopt out cats and dogs with ear mites and we have to send home ivermectin. If I put ivermectin into an oral dosing syringe and into a ziplock bag - how long would it stay good? Months?

Hi Jacustomer,

My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.

Each bottle of ivermectin has an expiration date on the bottle. Most bottles should also state storage procedures. The bottles I have state that it should be stored between 59F-86F. So it should stay good if stored correctly until the expiration date. In a lot of cases, ivermectin is quite safe for dogs and cats but not for all. Some dogs have a MDR1 mutation which makes them sensitive to ivermectin and other drugs. Read more on this here:

I hope this is not a stupid question... but if it is stored in a 1cc oral dosing syringe and in a zip lock - does that make a difference or not?

It shouldn't be a problem as long as it is tightly capped since in some cases, it is purchased in plastic syringes.
