Prescription Medicine For Cats

Reviewed by Dr. Melissa Witherell, DVM

Cat medicine can treat a wide range of health issues from occasional infections to chronic conditions. In many cases, medication works by alleviating symptoms (like pain or inflammation), though some treatments can correct the underlying cause of the issue itself. Cat medicine also includes vaccines and preventives used to protect against communicable diseases and pesky parasites. Here's a list of the most commonly prescribed cat medicines:

  • Flea and tick preventives: Oral and topical treatments to kill parasites and protect against future infestations
  • Urinary tract and kidney medicine: Drugs to support renal and urinary tract health
  • Antibiotics: Tablets, capsules, chewables, and liquids to treat bacterial infections
  • Dewormers: Anti-parasiticides to eradicate parasite infestations
  • Allergy medicine: Treatments for acute and chronic allergic reactions

Consult your veterinarian if you think your cat might be sick. Following diagnosis, your vet will recommend a course of treatment that might include giving your cat medicine. Consider filling your prescription using Chewy’s Autoship to enjoy fast and reliable recurring deliveries of your cat’s must-have medications.
