Educational reference. Always consult a doctor for diagnosis.
🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Tinzaparin binds to antithrombin III, causing a conformational change that accelerates the inactivation of factor Xa and, to a lesser extent, factor IIa (thrombin). This inhibits the coagulation cascade, preventing fibrin formation and clot propagation.
Mechanism Steps
💡 How to Take innohep 3500 iu injection
Strength: Injection: 3500 anti-Xa IU per 0.35 mL (or as specified by the manufacturer).
Dosage Information
| Adult Dosage | The dose of this medicine is individualized by a qualified clinician based on the indication, patient weight, and renal function. For treatment of DVT/PE, a common dose is 175 anti-Xa IU/kg once daily subcutaneously. For prophylaxis, 3500 anti-Xa IU once daily is often used. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may have reduced renal function and are at higher risk of bleeding. Dose should be individualized by a clinician, and renal function should be monitored. |
| Renal Impairment | In severe renal impairment (CrCl <30 mL/min), dose reduction or avoidance is recommended. For prophylaxis, 3500 anti-Xa IU once daily may be used with caution. For treatment, alternative anticoagulants may be preferred. Dose must be individualized by a qualified clinician. |
| Hepatic Impairment | No specific dose adjustments are established for hepatic impairment, but use with caution due to potential bleeding risk. Monitor closely. |
| Maximum Daily Dose | The maximum daily dose is individualized; for treatment, up to 175 anti-Xa IU/kg once daily is used. Do not exceed the prescribed dose. |

🤱 Lactation Safety
Tinzaparin is not excreted in breast milk to a significant extent and is considered safe during breastfeeding.
💊 Overdose Management
Overdose may cause severe bleeding. Administer protamine sulfate, which partially neutralizes tinzaparin's anti-IIa activity but has limited effect on anti-Xa activity. Supportive care and monitoring for bleeding are essential. Seek emergency medical attention.
⏰ Missed Dose
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double dose.
Additional Safety Advice
Use this medicine exactly as prescribed by your doctor. Do not change the dose or stop the injection without medical advice. Inform your doctor about all other medicines, especially blood thinners, aspirin, NSAIDs, and certain antidepressants. Avoid activities that increase the risk of injury or bleeding. Tell your healthcare provider if you are pregnant, planning pregnancy, or breastfeeding. Regular blood tests may be needed to check your platelet count and kidney function. Do not receive this medicine if you have active bleeding or a history of heparin-induced thrombocytopenia. Store the injection as directed and never share it with others.
