1. What is VENOFUSIN SODIUM BICARBONATE 1M and what is it used for
Venofusin Sodium Bicarbonate 1M is a solution for intravenous infusion belonging to the group of medicines called intravenous solutions that affect the electrolyte balance - Electrolytes.
It is indicated in the following situations:
- In the treatment of severe acute metabolic acidosis, which are clinical situations characterized by a decrease in blood pH and which may be caused by a loss of bicarbonate, such as after severe diarrhea or in renal tubular acidosis (kidney disorder that does not allow adequate regulation of bicarbonate), or by an excessive accumulation of acids in the body as occurs in ketoacidosis (accumulation of ketone bodies) or in lactic acidosis situations (accumulation of lactic acid).
- To increase the pH of urine in the treatment of acute intoxications of certain medications such as barbiturates or salicylates, in order to eliminate them quickly through the kidneys, or to decrease the toxic effects at the renal level that can occur after hemolytic reactions (reactions that cause the destruction of red blood cells)
2. What you need to know before using VENOFUSIN SODIUM BICARBONATE 1M
Do not use Venofusin Sodium Bicarbonate 1M
- If you are allergic to the active substance or to any of the other components of the medicine
- If you have alkalosis (increase in blood pH), either of metabolic or respiratory origin
- If you have low calcium levels in the blood (hypocalcemia), since the administration of this medicine in these situations can lead to tetany (prolonged muscle spasms)
- If you have excessive losses of chloride due to vomiting or gastrointestinal suction or hypochloremic alkalosis caused by diuretic medications
- If you have respiratory acidosis
Warnings and precautions
Be especially careful with Venofusin Sodium Bicarbonate 1M:
- during treatment, since the administration of sodium bicarbonate requires adequate pulmonary ventilation to correctly eliminate the formed carbon dioxide (CO2).
- during treatment, since the concentration of calcium and potassium in the blood may decrease during therapy with sodium bicarbonate. Your doctor may monitor and, if necessary, correct the levels of these electrolytes.
The administration of sodium bicarbonate should always be carried out under rigorous medical control, with periodic tests (such as blood tests) being performed.
Sodium bicarbonate can induce hypotension (decrease in blood pressure) in anesthetized patients.
Consult your doctor or pharmacist before starting to use Venofusin Sodium Bicarbonate 1M.
Using Venofusin Sodium Bicarbonate 1M with other medicines
Certain medications may interact with Venofusin Sodium Bicarbonate 1M. In this case, it may be necessary to change the dose or interrupt treatment with one of the medications.
In general, the concomitant administration of sodium bicarbonate with any medication that presents or may present renal toxicity should be avoided, as it can cause fluid and electrolyte retention.
It is important that you inform your doctor if you are using any of the following medications:
- corticosteroids with mineralocorticoid action (such as fludrocortisone) or ACTH (corticotropin).
- lithium carbonate.
- acidic medications such as salicylates and barbiturates.
- basic medications such as sympathomimetics (ephedrine, pseudoephedrine) and stimulants (amphetamine, dexamphetamine).
Tell your doctor or pharmacist if you are using or have recently used any other medications, including those obtained without a prescription.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
The safety of its use during pregnancy and breastfeeding has not been established. Therefore, it should only be used when clearly necessary and when the beneficial effects justify the possible risks to the fetus or baby.
Driving and using machines:
There is no indication that this medication may affect the ability to drive vehicles or operate complex machinery.
Important information about some of the components of Venofusin Sodium Bicarbonate 1M
Patients on low-sodium diets should note that this medication contains 22.9 g (1000 mmol) of sodium per liter.
3. How to use VENOFUSIN SODIUM BICARBONATE 1M
Venofusin Sodium Bicarbonate 1M is normally administered by infusion, diluted to isotonicity in other intravenous administration liquids with which there is physical compatibility, although it can also be administered undiluted by slow injection. In cases of extreme necessity, such as cardiac arrest (clinical situation that occurs with lactic acidosis), the medication can even be administered initially by rapid direct intravenous injection. If the hypertonic solution is administered, the central route should be used.
This medication will be used in a hospital by the corresponding healthcare personnel. In the case of peripheral administration, the medication must be diluted with a compatible solution.
Your doctor will indicate the duration and administration schedule of the treatment with Venofusin Sodium Bicarbonate 1M based on the intensity of the acidosis, laboratory tests, and your age, weight, and clinical condition.
It is recommended that the initial dose of sodium bicarbonate not exceed 50% of the calculated deficit, since the degree of response of the body to a given dose of sodium bicarbonate is not always predictable, due to the delayed action of the physiological compensation mechanisms. For this reason, it is recommended that during therapy, the acid-base state be frequently monitored, modifying the dose according to the response.
As a general rule, in adult patients in a situation of cardiac arrest, an initial dose of 1 mEq/kg of sodium bicarbonate can be administered intravenously, always ensuring adequate pulmonary ventilation.
Use in children and adolescents
In pediatric patients, an initial dose of 1 mEq/kg is recommended, administered by slow intravenous injection. In neonates, a 1:1 dilution of a sodium bicarbonate injection at 7.5 or 8.4% and a glucose injection at 5% (final solution at 4.2%) is recommended, without exceeding 8 mEq/kg per day.
If you are given more VENOFUSIN SODIUM BICARBONATE 1M than you should
Overdose or overdose in treatment with sodium bicarbonate can occur when the administration of the medication is excessive or too rapid, or in patients with renal insufficiency, and can lead to the development of metabolic alkalosis, hypocalcemia, hypokalemia (low potassium levels in the blood), paradoxical intracellular and cerebrospinal fluid acidosis (decrease in pH in cells and cerebrospinal fluid), hypotension, hypernatremia (high sodium levels in the blood), and hyperosmolarity (see section 4).
In case of overdose, the administration of the medication should be suspended and the electrolyte imbalance corrected.
In case of overdose or accidental ingestion, consult the Toxicology Information Service. Phone: 915 620 420.
If you have any further questions about the use of this medication, ask your doctor or pharmacist.

This information is intended only for doctors or healthcare professionals:
Treatment of metabolic acidosis should be aimed at correcting or improving the underlying disorder. Generally, the administration of sodium bicarbonate is only necessary in severe cases of metabolic acidosis (arterial pH below 7.20) or when it is not possible to determine or correct the cause of the acidosis.
The amount of sodium bicarbonate to be administered should not attempt to correct the acidosis completely. Sodium bicarbonate should be administered only to partially correct the pH to levels that do not pose a serious threat to life (around 7.20-7.30), allowing the physiological compensation mechanisms to complete the correction. The full and rapid correction to normal pH levels (7.30-7.40) involves problems of overdose.
This medication will be administered by specialized personnel. It will be administered by infusion, through a central or peripheral vein. It can be administered undiluted through a central vein or diluted with a compatible solution through a peripheral vein.
Venofusin Sodium Bicarbonate 1M is administered intravenously, normally diluted in other liquids for infusion, although it can also be administered undiluted by direct injection of the hypertonic solution.
The solution must be transparent and not contain precipitates. Do not administer otherwise.
The contents of each container are for single infusion, the unused fraction must be discarded.
Use an aseptic method to administer the solution and when preparing mixtures.
Before adding medications to the solution or administering them simultaneously with other medications, it should be checked that there are no incompatibilities.
Sodium bicarbonate has been shown to be physically and/or chemically incompatible with many medications, including acids, acid salts, and many alkaloid salts, but the incompatibility depends on different factors such as the concentration of the medications, the diluent used, the resulting pH, or the temperature. In many cases, the incompatibility is a consequence of the alkaline nature of the sodium bicarbonate solution.
In general, sodium bicarbonate solutions should not be mixed with acids in aqueous solutions, due to the release of CO2 that occurs when the bicarbonate is reduced by the acidic solution, nor with solutions that contain calcium salts due to the formation of insoluble complexes that can result from these combinations.
Sodium bicarbonate solutions should also not be mixed or administered in the same intravenous line with catecholamines (adrenaline) because the bicarbonate, being an alkaline solution, can inactivate the catecholamines.
As with other parenteral solutions, compatibility tables should be consulted before adding medications.
