Cautions:
Keep plenty of water available for your pet to drink. Furosemide can make your pet's skin more sensitive to sunlight. There are possible adverse interactions with other drugs, so fully disclose to your veterinarian what you are giving your pet. This medication should not be used in pregnant or nursing animals.
Precautions:
Not for use in animals who are hypersensitive (allergic) to it or sulfa drugs (furosemide is chemically similar to some sulfa drugs). Furosemide will cause your pet to urinate more often. Your pet may have more "accidents" and need to go outside or use the litter box more. Use with caution in animals with kidney disease and diabetes mellitus. Do not use in animals with anuria (inability to produce urine), progressive kidney disease, electrolyte imbalances, water loss (dehydration), liver disease, diabetes mellitus, vomiting, or diarrhea. Do not use in pregnant or lactating animals (female animals nursing their young). Your pet needs to eat and drink well while taking furosemide or the risk of side effects increases. Contact your veterinarian, if your pet is not eating or drinking well. Consult with your veterinarian regarding the physical examinations and laboratory testing necessary prior to and during treatment with furosemide.
Human Precautions:
People with hypersensitivities (allergies) to sulfa drugs should not handle furosemide, or wear gloves and use extreme caution if they do, since allergic reactions could occur just from contact.
Possible Side Effects
May include dehydration with excessive thirst and increased or decreased urine production; or electrolyte imbalances (e.g., low sodium, potassium, or calcium), often with rapid heart rate, weakness, depression, vomiting, and restlessness. If you see any of these signs, contact your veterinarian immediately. Less commonly may see an increase in blood glucose (sugar) level; anemia, resulting in pale gums, tiredness, or weakness; a decrease in white blood cells, making the animal more susceptible to infections; and stomach or intestinal disorders, with vomiting or diarrhea.
Cats: May affect hearing or balance, or cause a tilt of the head. Consult your veterinarian if you notice any of the above side effects. Animals who eat and drink normally are less likely to experience side effects. If your pet experiences an allergic reaction to the medication, signs may include facial swelling, hives, scratching, sudden onset of diarrhea, vomiting, shock, seizures, pale gums, cold limbs, or coma. If you observe any of these signs, contact your veterinarian immediately.

Signs of Toxity/Overdose:
