  • Gemfibrozil is a medication prescribed off-label by veterinarians to treat high levels of fat (lipids) in the blood of dogs and cats when dietary modifications have not been effective. Occasionally, it is also used in birds for the same purpose. As a relatively new drug in veterinary medicine, its benefits, side effects, and adverse effects are still being determined.

  • Gentamicin + betamethasone ophthalmic is a steroid anti-inflammatory eye medication with antibiotic used for the treatment of external eye infections and inflammation of the eye in dogs.

  • Giving pills to cats can be a challenge, even for the most experienced veterinarian! The easiest way to give your cat a pill is to hide the pill in food. Some cats will always find the pill and spit it out, so you may need to administer it directly into your cat's mouth. This handout provides a step-by-step guide to do this, along with some other options if it is still too difficult.
