Warnings and precautions

Consult your doctor or pharmacist before starting to use Heparin Sodium 1,000 UI/ml.

Heparin sodium may be administered by intravenous route (continuous infusion or intermittent injection), intra-arterial, or subcutaneous route (deep injection).

Intramuscular administration should be avoided due to the risk of local hematomas.

It is very important that you inform your doctor of all the diseases you have had or are having, in order to avoid the risk of bleeding, and especially:

• If you suffer from a disease or injury that may bleed, such as uncontrolled arterial hypertension, history of gastroduodenal ulcer, in case of ocular vascular disease (choroid or retina), kidney or urethra stones, or if you have recently undergone surgery
• If you have liver or kidney disease.
• If you have high potassium levels in the blood, as may occur if you have diabetes, chronic kidney disease, acidosis in the blood, or if you are taking medications that alter these levels, such as some diuretics. Your doctor may recommend monitoring potassium levels.
• If you have or have had low platelet counts (thrombocytopenia). Your doctor may recommend monitoring platelet counts.
• If you are going to undergo an intervention with spinal or epidural anesthesia, or if you are going to undergo a lumbar puncture.
• If it is administered to the elderly, special precautions should be taken, as with most medications.
• If it is administered to low-weight neonates, special precautions should be taken due to the risk of cerebral bleeding.

In case you are subjected to epidural or spinal anesthesia or a lumbar puncture, the doctor will perform an individual careful assessment of the benefit/risk ratio.

Other medicines and Heparin Sodium Sala 1,000 UI/ml

Use of Heparin Sodium 1,000 UI/ml with other medicines.

Tell your doctor or pharmacist if you are using, have recently used, or may need to use any other medicine.

Caution is recommended when administering heparin concomitantly with other anticoagulant medications, antiplatelet agents (ticlopidine), fibrinolytics, non-steroidal anti-inflammatory drugs (NSAIDs, such as aspirin, paracetamol, or ibuprofen), glucocorticoids, dextran, high doses of penicillin, and some cephalosporins (cefamandole, cefoperazone), some contrast media, and medications containing asparaginase, epoprostenol, or alprostadil.

Oral antidiabetics (sulfonylureas), medications used to treat anxiety containing benzodiazepines (chlordiazepoxide, diazepam, oxazepam).

The anticoagulant effect of heparin may decrease in patients treated with intravenous nitroglycerin, and it may be necessary to adjust the heparin dosage.

Medications that increase serum potassium concentration should only be taken under special medical supervision.

Pregnancy and breastfeeding

Consult your doctor or pharmacist before using any medicine.

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. He will give you the appropriate instructions.

Intravenous intermittent injections of heparin sodium are not recommended during pregnancy.

Heparin will be administered with caution and under continuous control, especially during the last trimester of pregnancy, and will be interrupted one or two days before the expected delivery date, given the risk of fetal-maternal hemorrhage.

Heparin sodium is not excreted in breast milk.

Elderly

If this medicine is administered to the elderly, there is a greater risk of bleeding (especially in women), particularly if the patient also suffers from liver and/or kidney failure.

Driving and using machines

Heparin sodium does not affect the ability to drive vehicles or use hazardous machinery or precision instruments.

Heparin Sodium Sala 1,000 UI/mlcontains less than 23 mg of sodium (1 mmol) per vial; this is, essentially "sodium-free".

It may produce allergic reactions (possibly delayed) and, exceptionally, bronchospasm (sudden feeling of suffocation) because it contains "sodium propyl parahydroxybenzoate (E-217)" and "sodium methyl parahydroxybenzoate (E-219)".

3. How to use Heparin Sodium Sala 1,000 UI/ml

Heparin Sodium Sala 1,000 UI/ml should be administered by a healthcare professional.

The vials containing Heparin Sodium Sala 1,000 UI/ml are ready for immediate use by intravenous route. It should not be administered by intramuscular route, and intramuscular injection of other agents should be avoided due to the risk of local hematomas during heparin sodium treatment. It can be used directly as a bolus or in continuous infusion with a perfusion pump. It can also be used as a subcutaneous injection. Your doctor will perform regular checks to control the doses. Follow the instructions unless your doctor has given you different instructions.

Your doctor will indicate the duration of your treatment with Heparin Sodium Sala 1,000 UI/ml. Do not stop treatment prematurely.

The dose of heparin sodium should be individualized according to the patient's weight and clinical situation. It should also be adjusted according to the coagulation time or the activated partial thromboplastin time (APTT). The recommended dose varies depending on the following indications:

Adults:

Heparin sodium can be administered by intravenous route (in continuous infusion or bolus), intra-arterial, or subcutaneous route. Intramuscular administration should be avoided due to the risk of local hematomas.

The dose of heparin should be individualized and adjusted according to the coagulation times. The recommended dose varies depending on the different indications, being in each case the following:

Adults:

Treatment and prevention of venous thromboembolic disease: deep vein thrombosis, pulmonary thromboembolism, and peripheral:

For the treatment of venous thromboembolism, an initial intravenous bolus of 80 UI/kg of heparin sodium (or 1,000 UI independently of weight) will be administered, which may be increased up to 120 UI/kg (or 7,500 UI independently of weight) in cases of severe pulmonary embolism. This initial dose will be continued with a maintenance dose, administered in continuous intravenous infusion, of 18 UI/kg (or 1,300 UI/h or 32,000 UI/24h, independently of weight). Subsequently, the dose should be individualized and adjusted according to the activated partial thromboplastin time (APTT), which should be maintained in a range between 1.5 and 2.5 times the control value. Control should be performed 4-6 hours after starting the infusion and at similar intervals whenever it is necessary to proceed with a variation of the administered dose. A treatment duration of 5-10 days is recommended.

In the prevention of venous thromboembolic disease, 1,000 UI will be administered subcutaneously every 8-10 hours for 7 days or until the patient is ambulatory.

In surgical patients, the first injection will be administered 1-2 hours before the intervention.

In non-surgical patients, the treatment duration will coincide with the duration of the thromboembolic risk.

Unstable angina or acute myocardial infarction without thrombolytic therapy:

An initial intravenous bolus of 1,000 UI of heparin sodium is recommended, followed by 32,000 UI/24h in continuous intravenous infusion adjusted according to APTT.

Acute myocardial infarction with thrombolytic therapy:

An initial intravenous bolus of 1,000 UI of heparin sodium is recommended, followed by 24,000 UI/24h in continuous intravenous infusion adjusted according to APTT.

Treatment and prevention of thrombosis in the extracorporeal circulation circuit during cardiac surgery and hemodialysis:

Cardiac surgery:it is recommended to heparinize the patient with 150-300 UI/kg, varying the dose according to the coagulation tests that are performed to control the levels of anticoagulation.

Hemodialysis:initially, 1,000 UI will be administered in bolus, in the arterial button of the hemodialysis circuit, continuing with a perfusion in saline serum of 750-1,000 UI/h throughout the entire hemodialysis session.

Children:

The dose of heparin should be adjusted according to weight and the required APTT levels. In general, for anticoagulation, 80 UI/kg will be administered in bolus, followed by 18 UI/kg/h, adjusting the dose to maintain an APTT between 1.5 and 2.5 times the control value. High doses should be avoided in low-weight neonates.

Elderly:

The dose of heparin should be adjusted according to weight and the required APTT levels.

Kidney and liver failure:

A lower dose may be necessary. The dose of heparin should be adjusted according to weight and the required APTT levels.

Pregnant women:

Prevention of venous thromboembolic disease:the administration of 1,000 UI, subcutaneously, every 8-12 hours, is usually adequate in the first months of pregnancy, and doses of up to 10,000 UI every 12 hours may be necessary during the third trimester of pregnancy.

Careful monitoring is recommended according to APTT.

Treatment of venous thromboembolic disease:it is recommended to administer heparin in intravenous bolus followed by continuous perfusion to maintain APTT levels in the therapeutic range for at least 5 days and subsequently subcutaneous doses every 12 hours adjusted to therapeutic APTT values, throughout the remainder of pregnancy.

Prophylaxis in pregnant women with cardiac valves:it is recommended to administer subcutaneous heparin every 12 hours at doses adjusted to maintain APTT values in the therapeutic range.
