Potasio Grifols 0.04 mEq/ml in 5% Glucose is an intravenous solution for restoring electrolyte balance containing electrolytes associated with carbohydrate hydrates.

Potasio Grifols 0.04 mEq/ml in 5% Glucose is indicated in the following situations:

• Hypokalemia (low potassium levels in the blood).
• Potassium depletion due to vomiting, diarrhea, gastrointestinal aspiration, or fistulas.
• Deficiencies in potassium-free nutrition.
• Prolonged treatments with potassium-depleting diuretics and corticosteroids.
• Primary or secondary hyperaldosteronism (increased production and secretion of aldosterone hormone).
• Tubular disorders with potassium elimination.
• Cardiac arrhythmias due to digitalis intoxication.
• Metabolic alkalosis (elevated blood pH due to low chloride ion concentration in the blood).
• Familial periodic paralysis with hypokalemia (hereditary disorder causing occasional episodes of muscle weakness, during which blood potassium levels are low).

Do not use Potasio Grifols 0.04 mEq/ml in Glucosa 5%

• if you are allergic to potassium chloride, glucose, or any of the other components of this medication (listed in section 6)
• if you have hyperkalemia (high levels of potassium in the blood) or hyperchloremia (high levels of chloride in the blood)
• if you have acute renal failure (kidney failure) or suppression or reduction of urine production
• if you have adrenal insufficiency (failure of the adrenal glands): Addison's disease or hypoadrenalism (decreased secretion of aldosterone hormone)
• if you suffer from extensive burns (initial phase)
• if you suffer from hemolytic crises (destruction of red blood cells in the blood)
• if you have metabolic or respiratory acidosis
• if you are under treatment with potassium-sparing diuretics or aldosterone inhibitors
• if you have familial periodic paralysis with hyperkalemia (hereditary disorder that produces occasional episodes of muscle weakness and may have higher-than-normal levels of potassium in the blood)
• if you are a digitalized patient with severe heart block, as in this case, the use of potassium salts is not recommended

Warnings and precautions

Consult your doctor or nurse before starting to use Potasio Grifols 0.04 mEq/ml in Glucosa 5%.

-Due to its glucose content, this medication should be administered with caution in diabetic patients, maintaining controlled blood glucose levels. Each 100 ml of this medication contains 5 g of glucose.

-Frequent monitoring of urine output, electrolyte balance, and blood glucose levels is recommended during treatment. Special vigilance is required for potassium levels and electrocardiogram during administration of solutions with potassium.

• This medication may become physiologically hypotonic in the body due to rapid glucose metabolism (see section 3).

-Depending on the volume and rate of infusion, your initial clinical condition, and your ability to metabolize glucose, the intravenous administration of this type of solution may cause electrolyte imbalances such as hyponatremia (low sodium levels in the blood).

Hyponatremia:

If you are a patient with non-osmotic vasopressin release (e.g., in the presence of critical states, pain, postoperative stress, infections, burns, and central nervous system diseases), if you have heart, liver, and kidney diseases, and if you are exposed to vasopressin agonists (see next subsection), you have a special risk of developing acute hyponatremia after administration of hypotonic solutions.

Acute hyponatremia can cause acute hyponatremic encephalopathy (cerebral edema) characterized by headache, nausea, seizures, lethargy, and vomiting. Patients with cerebral edema have a special risk of developing severe, irreversible, and potentially fatal brain damage.

Children, pregnant women, and patients with reduced cerebral compliance (e.g., in cases of meningitis, intracranial hemorrhage, and cerebral contusion) have a special risk of developing severe and potentially fatal cerebral edema caused by acute hyponatremia.

Other medications and Potasio Grifols 0.04 mEq/ml in Glucosa 5%

Inform your doctor if you are using, have used recently, or may need to use any other medication.

• Do not administer with medications that reduce kidney function.
• The concomitant administration of potassium salts with captopril may cause hyperkalemia.
• The concomitant administration with salt substitutes or potassium-sparing diuretics (spironolactone, triamterene, amiloride) may produce hyperkalemia that can be severe, especially in patients with renal insufficiency.
• The intravenous administration of hypotonic solutions together with medications that increase the effect of antidiuretic hormone (e.g., chlorpropamide, clofibrate, carbamazepine, vincristine, selective serotonin reuptake inhibitors, 3,4-methylenedioxy-N-methamphetamine, ifosfamide, antipsychotics, narcotics, nonsteroidal anti-inflammatory drugs, cyclophosphamide, desmopressin, oxytocin, vasopressin, terlipressin) that reduce water excretion in urine increases the risk of hospital-acquired hyponatremia (see previous subsection and sections 3 and 4).
• Diuretics in general and antiepileptic medications such as oxcarbazepine increase the risk of hyponatremia.

Pregnancy and lactation

If you are pregnant or breastfeeding, or if you think you may be pregnant or plan to become pregnant, consult your doctor before using this medication.

The safety of its use during pregnancy and lactation has not been established. Therefore, it should be used only when clearly necessary and when the benefits outweigh the potential risks for the fetus or infant.

This medication should be administered with special caution in pregnant women during delivery, especially if administered in combination with oxytocin, due to the risk of hyponatremia (see previous subsections and section 4).

Driving and operating machinery

Since this medication is administered only in hospitalized patients, no studies have been conducted on such effects.

The dosage will be established according to medical criteria depending on the degree of hypokalemia and the patient's clinical situation. Generally, 500-1000 ml per day at a rate of 20-30 drops/min is recommended via intravenous route. The maximum daily dose is 2000 ml at a rate of 60-80 drops/min.

You may need to monitor the patient's fluid balance, serum glucose, serum sodium, and other electrolytes before and during administration, especially if they have an increased non-osmotic release of vasopressin (syndrome of inappropriate antidiuretic hormone secretion, SIADH) and are receiving medication with vasopressin agonists simultaneously, due to the risk of hyponatremia. Monitoring serum sodium is especially important when administering hypotonic solutions. This medication may become hypotonic after administration due to the rapid metabolism of glucose in the body (see sections 2 and 4).

If you receive more Potasio Grifols 0.04 mEq/ml in Glucose 5% than you should

In case of overdose or too rapid administration, hyperkalemia may appear.

In case of hyperkalemia, administration should be suspended and symptomatic treatment should be performed, mainly to counteract the effects of potassium and stimulate its elimination.

For this, it is advisable to administer by intravenous perfusion sodium bicarbonate 1.4%, calcium chloride, or gluconate of calcium (10 or 20 ml of solution at 10%), or glucose (100 ml of solution at 50% or 1000 ml at 10%) along with 30 units of crystalline insulin.

In severe cases with renal insufficiency, hemodialysis or peritoneal dialysis should be performed to eliminate potassium from the body and correct hyperkalemia.

If there are electrocardiographic alterations due to excess potassium, it can be eliminated by administering orally or by enema an ionic exchange resin (sodium polystyrene sulfonate).

In case of overdose or accidental ingestion, consult the Toxicological Information Service. Phone: 915 620 420.

If you have any other questions about the use of this medication, ask your doctor or nurse.

Like all medications,this medicationcan produce adverse effects, although not everyone will experience them.

Adverse effects may occur if an excessive dose of potassium chloride is administered. If there are high levels of potassium in the blood (hyperkalemia), the following adverse effects may occur:

- Mental depression

- Confusion

- Paresthesia (abnormal sensation of the senses or general sensitivity)

- Muscle weakness and flaccid paralysis (loss of muscle strength and tone) of the extremities and respiratory muscles

- Bradycardia (decreased heart rate)

- Hypotension (decreased blood pressure)

- Electrocardiographic alterations

- Cardiac arrest

- Death

Hyperkalemia also produces a series of hormonal effects as it stimulates the secretion of aldosterone, insulin, and glucagon and inhibits the production of renin.

In patients with non-osmotic vasopressin release, in patients with heart, liver, and kidney diseases, and in patients treated with vasopressin agonists, the risk of acute hyponatremia increases after administration of hypotonic solutions. Hospital-acquired hyponatremia can cause irreversible brain damage and death due to the appearance of cerebral edema (see sections 2 and 3).
