Isopropyl Myristate Topical

What is isopropyl myristate topical?

Isopropyl myristate topical (brand name Resultix®) is a topical, non-insecticidal product containing an ester alcohol (isopropyl) and an acid (myristate). It is used to remove and kill attached, crawling ticks on cats and dogs.

It is used off label (extra label) in other species. Many drugs are commonly prescribed for off-label use in veterinary medicine. “Off label” means the drug is being used in a way that has not been reviewed or approved by the U.S. Food and Drug Administration (FDA) or Health Canada. In these instances, follow your veterinarian’s directions and cautions very carefully, as their directions may be significantly different from those on the label.

How do I give my pet isopropyl myristate topical?

• Isopropyl myristate topical comes in liquid spray form.
