Diuretics for cats and dogs are prescribed to remove excess fluid commonly caused by congestive heart failure. They can also be used to help treat high blood pressure. Many also reduce fluids and swelling by removing extra sodium from the kidneys. These medications are typically available in tablet form, but some are also available in liquid or injectable forms. Diuretics help your pet feel better quickly by reducing swelling that is uncomfortable. However most also cause excess urination, so be on the lookout for accidents. It’s important to make sure your pet doesn’t get dehydrated while taking diuretics and that their potassium levels don’t get too low.
