Cats + Medications & Supplements

  • Midazolam is a benzodiazepine used for its sedative, anti-anxiety, and muscle relaxant properties. It is primarily used as a sedative before surgery and to stop seizures. It is used “off label” or “extra label” in animals. This medication is a controlled substance primarily given via injection by your veterinary team, though it may be prescribed to your pet for intranasal or intrarectal administration at home.

  • Milbemycin oxime is a heartworm disease preventive and treats internal parasites (e.g., hookworms and roundworms) in dogs and cats. It is also found in combination products with other drugs. It is also used off label to treat infestations in dogs. Milbemycin is given by mouth with a flavored oral tablet. At regular doses, milbemycin is well-tolerated; when used at higher doses for treating mites, side effects have been observed. Some breeds of dogs (e.g., collies, sheepdogs, and collie- or sheepdog-cross breeds) are more sensitive to milbemycin than others; your veterinarian will advise you on the safety of milbemycin use in your dog. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.
