The Benefits of Cat and Dog Kidney Medications

When a dog or cat is diagnosed with acute or chronic kidney disease as the result of a trauma or illness, treatment usually consists of managing the underlying cause of the kidney disease. But, for pets that have developed kidney problems due their age or breed or are having other problems with their kidneys other than kidney disease, other medications are used to help improve their overall health and quality of life.

In this post, we’ll share some information about the most common medications prescribed to pets with kidney problems.

kidney meds for pets


Diuretics help kidneys flush toxins out of the body more efficiently because these drugs cause an increase in the excretion of water, sodium, chloride, and potassium to occur in the kidneys. Diuretics are prescribed whenever a pet has a problem with fluid retention (edema) or has an imbalance of electrolytes, mainly potassium and calcium. Common diuretics prescribed to pets include:

  • Furosemide
  • Chlorothiazide
  • Hydrochlorothiazide
  • Spironolactone

While diuretics can help the kidneys eliminate excess water and toxins from the body, they should never be administered to a pet with pre-existing kidney disease.


If the pet has an infection in her kidneys or in the urinary tract, then antibiotics will be prescribed to help get rid of the infection. But, not all antibiotics are best for these types of infections. A veterinarian will prescribe an antibiotic that is excreted in an active form in the urine. These types are best for treating urinary tract and kidney infections. Examples of these types of antibiotics include:


Amoxicillin/clavulanic acid






Although rare, dogs and cats can develop fungal infections in the urinary tract. In such cases, antifungal medications are used to help eliminate the infection. If the patient’s urine pH is causing a problem, then potassium citrate may be prescribed to raise it or Ammonium chloride or DL-methionine may be used to lower it. Common antifungals used in veterinary medicine include:

Cystine-Binding Agents

Cystine-binding agents like tiopronin or D-penicillamine are used to treat pets that have developed cystinuria with cystine urolith (stones) formation. These medications, along with changes in the pet’s diet, work by balancing the urine’s pH, which will ultimately cause the stones to dissolve.

ACE Inhibitors

If the pet is diagnosed with chronic kidney failure, then ACE inhibitors like benazepril, enalapril, and imidapril have been shown to reduce excess protein in the urine. They also prevent the blood vessels from narrowing, which helps maintain good blood flow to and from the kidneys.

Other Kidney-Related Drugs and Supplements

Muscle relaxants are often prescribed to pets with kidney issues because they help relax the urethral muscles, which is important for preventing urine retention. In some cases, adrenergic antagonists such as metoprolol or acebutalol may be prescribed to help improve vascular function or cholinergic agonists like bethanechol may be used to stimulate the urinary bladder.
