Lasix Oral Solution (Furosemide)

Lasix is a liquid oral diuretic medication that contains Furosemide as the active ingredient. It is a human medication that may be prescribed off-label by a veterinarian for use in pets. Furosemide is an effective diuretic commonly used for treating fluid retention (oedema) in cats and dogs. It may be prescribed to help treat congestive heart failure, certain types of kidney disease, and lung fluid retention.

Furosemide is a medication that acts as a diuretic, helping to remove excess fluid from your pet's body. It works by stopping the kidneys from reabsorbing sodium and chloride. This prevents water from being reabsorbed into the bloodstream, which leads to more urination and removes excess fluid. It is known for its rapid onset and can lower blood pressure by decreasing blood volume. However, it may also lead to a loss of electrolytes like potassium, so it requires careful monitoring. Furosemide should always be administered under veterinary supervision to ensure correct dosing and monitor for any side effects.

It is important to carefully follow the specific instructions from your veterinarian when administering Lasix to ensure proper dosing and administration. Ensure your pet has access to water at all times while being treated with Lasix.

Missed Dose:

If you miss a dose, give it as soon as you remember. However, if it is close to their next dose, skip the missed dose and give the next dose as scheduled. Do not double dose.

Overdose:

Contact your veterinarian immediately or the New Zealand National Poisons Centre (http://www.poisons.co.nz/animal-helpline/ or phone 0800 869 738).

Hypersensitivity: Do not use it in animals with a known hypersensitivity or allergy to furosemide.

Electrolyte Imbalance: Avoid use in animals with significant electrolyte imbalances (e.g. hypokalemia, hyponatremia) until corrected.

Renal Failure: Avoid using in animals with advanced renal failure, where the drug might not produce diuretic effects and could exacerbate the condition.

Dehydration: Not recommended in animals that are dehydrated, as it can worsen dehydration and affect kidney function.

Pregnancy and Lactation: Avoid or use cautiously in pregnant or lactating animals, as safety in these groups has not been fully established.

While Lasix is generally well-tolerated, all medication may cause side effects. This can include increased urination and thirst, dizziness, and signs of dehydration or electrolyte imbalance (extreme thirst, reduced urination, and confusion). Other symptoms may involve irregular heartbeat, muscle cramps, seizures and gastrointestinal problems like loss of appetite, nausea, and vomiting.

Store this medication under controlled room temperatures, protected from moisture and light, and out of reach of children and pets.
