Lasix Oral Solution

The active ingredient in Lasix oral solution is furosemide. It is a loop diuretic that acts on the kidneys to help excrete more water, sodium, and potassium and lower swelling and blood pressure (antihypertensive).

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide, before using furosemide oral solution. However, the following is a synopsis of the general guidelines for the use of Lasix oral solution:

• You should take this medication in the morning or early afternoon to avoid getting up in the night to use the bathroom.
• This medication can cause dizziness, especially in the first few days or when going up in dose. To minimize this effect, get up slowly.
• Furosemide can make you more sensitive to the sun. To minimize the risk of burning, avoid tanning beds or spending too long in the sun, and always wear sunscreen, wide-brimmed hats, and long sleeves to protect your skin.
• This medication can increase your blood sugar (hyperglycemia). If you are diabetic, check your blood sugars more frequently while on this medication.
• It is important to hydrate while taking this medication, as directed by your doctor.
• If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your next scheduled dose. Do not take two doses at the same time.

• Frequent urination.

• Severe dehydration or electrolyte imbalance (low calcium - hypocalcemia, low magnesium - hypomagnesemia, low sodium - hyponatremia, low potassium - hypokalemia) may present as dry mouth, feeling thirsty, drowsiness,irregular heartbeat, or low blood pressure.
• Severe skin reactions may present as painful blisters, rash, or peeling skin.
• Severe allergic reactions may present as hives, trouble breathing, lightheadedness, tightness in the throat, and swelling of the face.
• Hearing loss (ototoxicity) may present as tinnitus (ringing in the ears) and is more common when given as an injection or at high doses.

These are not all of the possible side effects of Lasix oral solution. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

• Kidney problems.
• Liver problems, including hepatic cirrhosis or ascites - the initial dose should be given in the hospital.
• Urinary retention or enlarged prostate - furosemide may worsen this effect.
• Systemic lupus erythematosus.

When Lasix oral solution is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:

• Aminoglycoside antibiotics (gentamycin, erythromycin, and tobramycin), cisplatin, and ethacrynic acid may increase the risk for ototoxicity when used with furosemide.
• Corticosteroids and laxatives may increase the risk of electrolyte imbalances when used with furosemide.
• Lithium, as there is an increased risk of lithium toxicity when used with furosemide.
• ACE inhibitors (ramipril, perindopril) and ARBs (candesartan, valsartan, irbesartan) should not be used with furosemide, as this can lead to severe hypotension or kidney dysfunction.
• Use with sucralfate should be avoided as this medication may reduce the efficacy of furosemide.
• Use of intravenous chloral hydrate within 24 hours of taking furosemide can lead to flushing, sweating, restlessness, hypertension, or nausea.
• Phenytoin can decrease the absorption of Lasix oral solution.
• Methotrexate and other drugs that undergo significant renal tubular secretion can reduce the efficacy of furosemide, and Lasix oral solution may decrease the renal elimination of other drugs.
• Lasix oral solution may increase the risk of nephrotoxicity from cephalosporin antibiotics.
• The use of Lasix oral solution with cyclosporine may increase the risk of gouty arthritis.
