Cat Medications & Health Conditions
Cats present unique pharmacological challenges. Their liver lacks certain glucuronidation enzymes, making them extremely sensitive to drugs that are safe in dogs and humans — acetaminophen (Tylenol), for example, is fatal to cats even in small doses. Many feline conditions, including hyperthyroidism, chronic kidney disease, and diabetes, require lifelong medication and careful monitoring. Understanding your cat's medications, their potential side effects, and the importance of consistent dosing helps you partner effectively with your veterinarian for the best outcome.
Common Conditions in Cats
Cats are prone to a distinct set of diseases compared to dogs, particularly endocrine and urinary conditions. Many feline diseases are chronic and progressive, requiring long-term management.

- ProZinc (protamine zinc insulin) — FDA-approved insulin for cats
Kidney & Urinary
- Benazepril — ACE inhibitor for kidney disease
- Telmisartan (Semintra) — ARB for feline CKD
- Aluminum Hydroxide — Phosphate binder for renal patients
- Prazosin — Urethral relaxant for FLUTD
Respiratory
- Fluticasone Propionate Inhaler — Inhaled corticosteroid for feline asthma
- Albuterol Inhaler — Rescue bronchodilator
- Prednisolone — Oral corticosteroid for asthma and IBD
Pain Management
- Solensia (frunevetmab) — Monthly anti-NGF injection for osteoarthritis pain
- Buprenorphine (Simbadol) — Opioid for acute pain
- Meloxicam — NSAID (short-term use only in cats due to kidney risk)
- Gabapentin — Nerve pain, anxiety, and pre-vet sedation
Heart & Cardiovascular
- Atenolol — Beta-blocker for HCM
- Clopidogrel (Plavix) — Antiplatelet to prevent aortic thromboembolism

- Fluoxetine — SSRI for chronic anxiety and inappropriate elimination
- Trazodone — Situational anxiety
Appetite Stimulants & GI Support
