1. What is Furosemide Mabo and what is it used for

Furosemide is a diuretic belonging to the group of sulfonamides. It acts by increasing urine elimination (diuretic) and reducing blood pressure (antihypertensive).

Always under the prescription of your doctor, this medicine is indicated for the treatment of:

• Edema (swelling due to fluid accumulation) associated with congestive heart failure, liver cirrhosis (ascites), and kidney disease, including nephrotic syndrome (priority is given to the treatment of the underlying disease).
• Edema following burns.
• Mild and moderate arterial hypertension.

2. What you need to know before you take Furosemide Mabo

Read carefully the instructions provided in section 3. “How to take Furosemide Mabo”.

Do not take Furosemide Mabo

• If you are allergic to furosemide, to medicines of the Furosemide Mabo type (sulfonamides) or to any of the other components of this medicine (included in section 6).
• In case of decreased total blood volume (hypovolemia) or dehydration.
• If you have severe kidney problems, accompanied by a decrease in urine elimination (renal insufficiency with anuria), that do not respond to this medicine.

• If you have a severe decrease in potassium levels in the blood (severe hypokalemia) (see section 4. “Possible side effects”).

• If you have a severe deficiency of sodium salts in the blood (severe hyponatremia).
• In case of pre-coma and coma associated with hepatic encephalopathy.
• If you are breastfeeding a baby.
• If you are pregnant, see section “Pregnancy, breastfeeding, and fertility”.

Warnings and Precautions

Consult your doctor or pharmacist before starting to take furosemide.

Be especially careful with this medicine:

• If you have problems with urine elimination, especially at the start of treatment.
• If your blood pressure is low (hypotension).
• If you are at special risk of suffering a pronounced drop in blood pressure (for example, in patients with significant coronary or cerebral stenosis).
• If you have latent or manifest diabetes mellitus.
• If you suffer from gout.
• If you have severe kidney problems associated with severe liver disease (hepato-renal syndrome).
• If your blood protein levels are low (hypoproteinemia), in addition to suffering from, for example, nephrotic syndrome (see section 4. “Possible side effects”).
• In premature children (see section 4. “Possible side effects”).
• There is a possibility of exacerbation or activation of systemic lupus erythematosus.
• If you are an elderly person, if you are being treated with medicines that can cause a decrease in blood pressure or if you have other medical conditions that have associated risk of decreased blood pressure.

During your treatment with this medicine, periodic control of your blood levels of sodium, potassium, and creatinine will generally be required, especially if you suffer from severe fluid loss, due to vomiting, diarrhea, or intense sweating. Dehydration or hypovolemia, as well as any significant electrolyte and acid-base balance alterations, should be corrected. Treatment interruption may be required.

Elderly patients with dementia who are taking risperidone should be especially careful with the concomitant use of risperidone and furosemide. Risperidone is a medicine used to treat certain mental illnesses, such as dementia (a disease characterized by several symptoms: memory loss, speech problems, thinking problems).

Use in Athletes

This medicine contains furosemide, which may produce a positive result in doping tests.

Use of Furosemide Mabo with Other Medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

The effect of the treatment may be affected if furosemide is used at the same time as other medicines.

Some substances may increase their toxicity in the ear or kidneys if administered together with this medicine. Therefore, they should only be administered together if there are medical reasons that require it.

These substances include:

• Aminoglycoside antibiotics (infection medicines) such as gentamicin, kanamycin, and tobramycin.
• Cancer medicines (cisplatin).

Your doctor may need to change your dose and/or take other precautions if you are taking one of the following medicines:

• Aliskiren - used to treat high blood pressure.

The concomitant use of furosemide with other medicines may weaken the effect of these medicines, such as:

• Medicines used for diabetes (antidiabetics).
• Medicines used to increase blood pressure (sympathomimetics with a hypertensive effect, for example, epinephrine and norepinephrine).

In other cases, concomitant use may increase the effects of these medicines, such as:

• Medicines for asthma (theophylline).

• Muscle relaxants like curare.
• Medicines for depression (lithium salts): may increase the risk of lithium toxicity, including the risk of harmful effects on the heart or brain.
• Patients undergoing treatment with diuretics may suffer from severe hypotension and deterioration of kidney function, especially when an ACE inhibitor (Angiotensin-Converting Enzyme) or an angiotensin II receptor antagonist is administered for the first time or at a high dose.
• If medicines to treat high blood pressure, diuretics, or other medicines that can decrease blood pressure are administered together with furosemide, a more pronounced drop in blood pressure should be anticipated.
• Nephrotoxic medicines: concomitant administration may potentiate the harmful effect of these medicines on the kidneys.

Some medicines for inflammation and pain (non-steroidal anti-inflammatory drugs, including acetylsalicylic acid) and medicines for epilepsy (phenytoin) may reduce the effect of furosemide.

Furosemide may increase the toxicity of salicylates.

This medicine and sucralfate should not be administered together, with an interval of less than 2 hours, as the effect of furosemide may be reduced.

Medicines such as probenecid and methotrexate or other medicines that have significant renal elimination may reduce the effect of furosemide. In high-dose treatment, they may increase serum levels and increase the risk of side effects due to furosemide or concomitant administration.

The following substances may increase the risk of reducing potassium levels in the blood (hypokalemia) if administered with furosemide:

• Medicines for inflammation (corticosteroids).
• Carbenoxolone (medicine for the treatment of oral mucosa lesions).
• Large amounts of licorice.
• Prolonged use of laxatives for constipation.

Some electrolyte disturbances (for example, decreased potassium or magnesium levels in the blood) may increase the toxicity of some medicines (for example, digitalis medicines and medicines that induce QT interval prolongation syndrome).

Patients undergoing treatment with furosemide and receiving high doses of certain cephalosporins (antibiotics) may suffer from decreased kidney function.

The concomitant administration of furosemide and cyclosporin A (a medicine used to prevent transplant rejection) is associated with an increased risk of gouty arthritis (joint inflammation) secondary to increased blood urea levels and kidney urea elimination problems.

Patients at high risk of suffering from nephropathy (kidney disease) due to contrast media who receive furosemide are more likely to suffer from kidney function deterioration.

The administration of furosemide together with risperidone in elderly patients with dementia could increase mortality.

High doses of furosemide administered with levothyroxine may lead to a transient initial increase in free thyroid hormones, followed by a general decrease in total thyroid hormone levels.

Pregnancy, Breastfeeding, and Fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

If you are pregnant, you will only use furosemide if there are medical reasons that require it.

During breastfeeding, do not administer furosemide. If its administration is essential, your doctor may require you to interrupt breastfeeding, as furosemide passes into breast milk.

Driving and Using Machines

This medicine may cause dizziness or drowsiness. This may occur more frequently at the start of treatment, when your doctor increases the dose, or if you consume alcohol. Do not drive or use tools or machines if you feel dizzy or drowsy.

Some side effects (e.g., a pronounced undesirable drop in blood pressure) may impair your ability to concentrate and react, and therefore constitute a risk in situations where these skills are especially important (e.g., operating vehicles or machinery).

Furosemide Mabo Contains Sodium

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; that is, it is essentially “sodium-free”.
