Older people may not respond as well to the initial diuretic effect of Lasix. May not be suitable for some people including those with cirrhosis of the liver or ascites, kidney disease, or who are already electrolyte depleted or dehydrated.
May interact with a number of other drugs including potassium, lithium, corticosteroids, digoxin, phenytoin, and methotrexate as well as those that also lower blood pressure.
Note: In general, seniors or children, people with certain medical conditions such as liver or kidney problems, heart disease, diabetes, seizures or people who take other medications are more at risk of developing a wider range of side effects. View complete list of side effects 4. Bottom Line Lasix is a strong diuretic that increases urination which relieves excess fluid from the body. This may also lead to the depletion of certain electrolytes, such as potassium.
Tips Dosages vary from individual to individual and people taking high dosages may need extra monitoring by their doctor. Some individuals may only need to take Lasix two to four times per week. You may be more sensitive to sunlight while taking Lasix. Tell your doctor if you develop diarrhea or vomiting while taking Lasix. Get up slowly when going from a lying down or sitting position to standing because Lasix may make you feel dizzy.
Your electrolyte levels will need regular monitoring and your blood may need occasional testing for diabetes. If you already have diabetes, be aware that Lasix may increase your blood glucose levels. Potassium supplements or extra dietary potassium may be needed to counteract the effects of low potassium levels caused by Lasix. Response and Effectiveness The onset of diuresis increased urination is within an hour. Peak effects are seen within one to two hours and the effects of Lasix last for 6 to 8 hours.
Interactions Medicines that interact with Lasix may either decrease its effect, affect how long it works for, increase side effects, or have less of an effect when taken with Lasix.

- What is Lasix?
Older people may not respond as well to the initial diuretic effect of Lasix. Get up slowly and steady yourself to prevent a fall. Indomethacin may also affect plasma renin levels, aldosterone excretion, and renin profile lasix.
Other medications may also influence serum electrolytes. Conversely, Lasix may decrease renal elimination of other drugs that undergo tubular secretion.
Your lasix levels will need regular monitoring and your blood may need occasional testing for report. Tips Dosages vary from individual to individual and people taking high dosages may need extra monitoring by their doctor. Serum and urine electrolyte determinations are particularly important when push patient is vomiting profusely or receiving parenteral fluids.
Do not take more than your recommended dose.
One study in six subjects demonstrated that the combination of furosemide and acetylsalicylic acid temporarily reduced creatinine clearance in patients with chronic renal insufficiency. How should I take Lasix? Chemically, it is 4-chloro-N-furfurylsulfamoylanthranilic acid.

The action on the distal tubule is independent of any inhibitory effect on carbonic anhydrase and aldosterone. Recent evidence suggests that furosemide glucuronide is the only or at least the major biotransformation product of furosemide in man. Furosemide is extensively bound to plasma proteins, mainly to albumin. The unbound fraction averages 2. The onset of diuresis following oral administration is within 1 hour.
The peak effect occurs within the first or second hour. The duration of diuretic effect is 6 to 8 hours. Although furosemide is more rapidly absorbed from the oral solution 50 minutes than from the tablet 87 minutes , peak plasma levels and area under the plasma concentration-time curves do not differ significantly.
Peak plasma concentrations increase with increasing dose but times-to-peak do not differ among doses. The terminal half-life of furosemide is approximately 2 hours. Significantly more furosemide is excreted in urine following the IV injection than after the tablet or oral solution. There are no significant differences between the two oral formulations in the amount of unchanged drug excreted in urine.
Geriatric Population Furosemide binding to albumin may be reduced in elderly patients. Furosemide is predominantly excreted unchanged in the urine. The renal clearance of furosemide after intravenous administration in older healthy male subjects 60 to 70 years of age is statistically significantly smaller than in younger healthy male subjects 20 to 35 years of age.
Indications and Usage for Lasix Edema Lasix is indicated in adults and pediatric patients for the treatment of edema associated with congestive heart failure, cirrhosis of the liver, and renal disease, including the nephrotic syndrome. Lasix is particularly useful when an agent with greater diuretic potential is desired. Hypertension Oral Lasix may be used in adults for the treatment of hypertension alone or in combination with other antihypertensive agents.
Hypertensive patients who cannot be adequately controlled with thiazides will probably also not be adequately controlled with Lasix alone. Contraindications Lasix is contraindicated in patients with anuria and in patients with a history of hypersensitivity to furosemide. Warnings In patients with hepatic cirrhosis and ascites, Lasix therapy is best initiated in the hospital.
In hepatic coma and in states of electrolyte depletion, therapy should not be instituted until the basic condition is improved. Sudden alterations of fluid and electrolyte balance in patients with cirrhosis may precipitate hepatic coma; therefore, strict observation is necessary during the period of diuresis. Supplemental potassium chloride and, if required, an aldosterone antagonist are helpful in preventing hypokalemia and metabolic alkalosis. If increasing azotemia and oliguria occur during treatment of severe progressive renal disease, Lasix should be discontinued.
Cases of tinnitus and reversible or irreversible hearing impairment and deafness have been reported. Reports usually indicate that Lasix ototoxicity is associated with rapid injection, severe renal impairment, the use of higher than recommended doses, hypoproteinemia or concomitant therapy with aminoglycoside antibiotics, ethacrynic acid, or other ototoxic drugs. Precautions General Excessive diuresis may cause dehydration and blood volume reduction with circulatory collapse and possibly vascular thrombosis and embolism, particularly in elderly patients.
As with any effective diuretic, electrolyte depletion may occur during Lasix therapy, especially in patients receiving higher doses and a restricted salt intake. Hypokalemia may develop with Lasix, especially with brisk diuresis, inadequate oral electrolyte intake, when cirrhosis is present, or during concomitant use of corticosteroids, ACTH, licorice in large amounts, or prolonged use of laxatives.
Digitalis therapy may exaggerate metabolic effects of hypokalemia, especially myocardial effects. All patients receiving Lasix therapy should be observed for these signs or symptoms of fluid or electrolyte imbalance hyponatremia, hypochloremic alkalosis, hypokalemia, hypomagnesemia or hypocalcemia : dryness of mouth, thirst, weakness, lethargy, drowsiness, restlessness, muscle pains or cramps, muscular fatigue, hypotension, oliguria, tachycardia, arrhythmia, or gastrointestinal disturbances such as nausea and vomiting.
Increases in blood glucose and alterations in glucose tolerance tests with abnormalities of the fasting and 2-hour postprandial sugar have been observed, and rarely, precipitation of diabetes mellitus has been reported.
In patients with severe symptoms of urinary retention because of bladder emptying disorders, prostatic hyperplasia, urethral narrowing , the administration of furosemide can cause acute urinary retention related to increased production and retention of urine. Thus, these patients require careful monitoring, especially during the initial stages of treatment. In patients at high risk for radiocontrast nephropathy, Lasix can lead to a higher incidence of deterioration in renal function after receiving radiocontrast compared to high-risk patients who received only intravenous hydration prior to receiving radiocontrast.
In patients with hypoproteinemia e. Follow your doctor's instructions about using potassium supplements or getting enough salt and potassium in your diet. While using Lasix, you may need frequent blood tests. Keep using this medicine as directed, even if you feel well.
High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life. If you need surgery, tell the surgeon ahead of time that you are using Lasix.
Store at room temperature away from moisture, heat, and light. Throw away any Lasix oral solution liquid 90 days after opening the bottle, even if it still contains unused medicine. Detailed Lasix dosage information What happens if I miss a dose?
Lasix is sometimes used only once, so you may not be on a dosing schedule. If you are using the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose. What happens if I overdose? Seek emergency medical attention or call the Poison Help line at Overdose symptoms may include feeling very thirsty or hot, heavy sweating, hot and dry skin, extreme weakness, or fainting.
Tips Dosages vary from individual to individual and people taking high dosages may need extra monitoring by their doctor. Some individuals may only need to take Lasix two to four times per week.
You may be more sensitive to sunlight while taking Lasix. Tell your doctor if you develop diarrhea or vomiting while taking Lasix. Get up slowly when going from a lying down or sitting position to standing because Lasix may make you feel dizzy. Your electrolyte levels will need regular monitoring and your blood may need occasional testing for diabetes.
If you already have diabetes, be aware that Lasix may increase your blood glucose levels. Potassium supplements or extra dietary potassium may be needed to counteract the effects of low potassium levels caused by Lasix. Response and Effectiveness The onset of diuresis increased urination is within an hour.
Peak effects are seen within one to two hours and the effects of Lasix last for 6 to 8 hours. Interactions Medicines that interact with Lasix may either decrease its effect, affect how long it works for, increase side effects, or have less of an effect when taken with Lasix. An interaction between two medications does not always mean that you must stop taking one of the medications; however, sometimes it does.
