Overview
Antihistamines such as hydroxyzine (Atarax®), diphenhydramine (Benadryl®), and chlorpheniramine (Chlor-Trimeton®) are used in veterinary medicine primarily to treat allergies that cause skin problems. Less often, they are prescribed to prevent carsickness, to treat severe allergic reactions to insect bites or stings, or as sedatives.
In veterinary medicine, sulfadimethoxine is used primarily to treat coccidia (Isospora) in puppies and kittens. Courses of sulfadimethoxine generally last from 3 to 21 days.
Sulfadimethoxine also may be used as an antibiotic, but this is not common in veterinary medicine.
Sulfadimethoxine is currently considered an inferior treatment option for coccidia. A different drug, ponazuril, is preferred.
Enalapril and benazepril are related members of a class of drugs called ACE inhibitors. They have similar effects and uses in veterinary medicine.
Methimazole is used to treat hyperthyroidism in cats. It works by blocking the thyroid gland from making thyroid hormone. The effect is temporary. Most cats with hyperthyroidism require lifelong treatment with methimazole unless other, permanent treatment options are pursued. More details on these options are available on the page entitled Hyperthyroidism in Cats.
Levothyroxine is used to treat hypothyroidism in dogs. It works by supplementing the dog’s production of thyroid hormone. The effect is temporary. Most dogs with hypothyroidism require lifelong treatment with levothyroxine.
Levothyroxine most commonly is administered as an oral pill once or twice daily.
Side effects of levothryoxine are rare but can include gastrointestinal upset.
Insulin is a drug that is used in the treatment of diabetes in dogs and cats. It requires special handling and storage, it must be given by injection, and it carries the risk of overdose. Despite these disadvantages, insulin is the most commonly used drug in the treatment of diabetes. Without insulin, most diabetic cats and dogs will suffer severe or fatal complications of the disease.
