5.Storage of furosemide cinfa

6.Contents of the pack and additional information

Furosemida cinfa is a diuretic belonging to the sulfonamides group. It acts by increasing urine elimination (diuretic) and reducing blood pressure (anti-hypertensive).

Under the prescription of your doctor, this medication 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 should be given to the treatment of the underlying disease).
• Edemas following burns.
• Mild to moderate arterial hypertension.

Do not take furosemide cinfa

• If you are allergic to furosemide, to sulfonamide medications, or to any of the other components of this medication (listed in section 6).
• If you have a decrease in your total blood volume (hypovolemia) or are dehydrated.
• If you have severe kidney problems, accompanied by a decrease in urine elimination (renal insufficiency with anuria), that do not respond to this medication.
• If you have a severe decrease in your blood potassium levels (severe hypokalemia) (see section 4 “Possible side effects”).
• If you have a severe deficiency of sodium salts in your blood (severe hyponatremia).
• If you are in a pre-comatose and comatose state associated with hepatic encephalopathy.
• If you are breastfeeding a baby.

If you are pregnant, see the section “Pregnancy, lactation, and fertility”.

Warnings and precautions

Consult your doctor or pharmacist before starting to take furosemide cinfa.

Be especially careful with this medication:

-If you have problems with urine elimination, especially at the beginning of treatment.

-If your blood pressure is low (hypotension).

-If you have a 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 have gout.

-If you have severe kidney problems, associated with a severe liver disease (hepato-renal syndrome).

-If your blood protein levels are low (hypoproteinemia), in addition to having, for example, a 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 medications that may cause a decrease in blood pressure, or if you have other medical conditions that are associated with the risk of a decrease in blood pressure.

During your treatment with this medication, you will generally require periodic monitoring of your blood levels of sodium, potassium, and creatinine, and especially if you have a severe loss of fluids, by vomiting, diarrhea, or intense sweating. Dehydration or hypovolemia, as well as any significant electrolyte and acid-base balance alterations, should be corrected. The treatment may need to be interrupted.

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

Use in athletes

This medication contains furosemide, which can produce a positive result in doping control tests.

Taking furosemide cinfa with other medications

Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.

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

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

Among these substances are:

• Aminoglycoside antibiotics (infection medications) such as gentamicin, kanamicin, and tobramicin.
• Cancer medications (cisplatin).

The concomitant use of furosemide with other medicationsmay weaken the effect of these medications such as

• Medications used for diabetes (antidiabetic medications).
• Medications used to raise blood pressure (sympathomimetics with a hypertensive effect, for example, epinephrine and norepinephrine).

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

• Asthma medications (theophylline).
• Muscle relaxants such as curare.
• Depression medications (lithium salts): it may increase the risk of lithium toxicity, including the risk of harmful effects on the heart or brain.
• Patients being treated with diuretics may suffer from severe hypotension and renal function deterioration, especially when administered for the first time or when administered for the first time a high dose of an ACE inhibitor (Angiotensin-Converting Enzyme), or an angiotensin II receptor antagonist.
• If blood pressure-lowering medications, diuretics, or other medications that may lower blood pressure are administered together with furosemide, a more pronounced drop in blood pressure should be anticipated.
• Kidney-damaging medications: the concomitant administration may potentiate the harmful effect of these medications on the kidneys.

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

Furosemide may increase the toxicity of salicylates.

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

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

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

• Anti-inflammatory medications (corticosteroids).
• Carbenoxolone (medication for the treatment of oral mucosa lesions).
• Significant amounts of licorice root.
• Prolonged use of laxatives for constipation.

Some electrolyte alterations (for example, a decrease in blood potassium levels (hypokalemia), or magnesium (hypomagnesemia)) may increase the toxicity of some medications (for example, digitalis medications and medications that induce the QT interval prolongation syndrome).

Patients being treated with furosemide and receiving high doses of some cephalosporins (antibiotics) may suffer from kidney function deterioration.

The concomitant administration of furosemide and cyclosporine A (medication used to prevent transplant rejection) is associated with a high risk of secondary gouty arthritis (inflammation of the joints) due to an increase in blood urea levels (hyperuricemia) and problems with urea elimination by the kidneys.

Patients with a high risk of suffering from nephropathy (kidney disease) due to radiocontrast agents who receive furosemide have a higher risk of kidney function deterioration.

The concomitant administration of furosemide with risperidone in patients with advanced age and dementia may increase mortality.

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

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

• Aliskiren - used to treat high blood pressure.

Pregnancy, lactation, and fertility

If you are pregnant or breastfeeding, consult your doctor or pharmacist before using this medication.

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

During lactation, furosemide should not be administered. If its administration is necessary, your doctor may require you to interrupt lactation, as furosemide passes into breast milk.

Driving and operating machines

This medication may cause dizziness or somnolence. This may occur more frequently at the beginning of treatment, when your doctor increases your dose, or if you consume alcohol. Do not drive or operate tools or machines if you feel dizzy or somnolent.

Some adverse effects (e.g. a pronounced and undesirable drop in blood pressure) may impair the ability to concentrate and react, and therefore constitutes a risk in situations where these skills are of special importance (e.g. operating vehicles or machinery).
