Medical Editor: John P. Cunha, DO, FACOEP
Innohep (tinzaparin) is used together with warfarin (Coumadin) to treat a type of blood clot called deep vein thrombosis, or DVT. This condition sometimes occurs with a blood clot in lungs (pulmonary embolism, or PE). It is a blood thinner (anticoagulant). Common side effects include pain, bruising, redness, and swelling at the injection site. Headache, nosebleed, or fever may also occur.
The recommended dose of Innohep for the treatment of DVT with or without PE is 175 anti-Xa IU/kg of body weight, administered subcutaneously once daily for at least 6 days and until the patient is adequately anticoagulated with warfarin (INR at least 2.0 for two consecutive days). Innohep may interact with dextran, aspirin and other salicylates, and other medication used to prevent blood clots. Tell your doctor all medication you are taking. During pregnancy, Innohep should be used only when prescribed. If you become pregnant or think you may be pregnant, tell your doctor immediately. Since the benzyl alcohol in Innohep can affect a fetus a preservative-free product should be used in pregnant women if possible. It is not known whether this drug passes into breast milk. Consult your doctor before breast-feeding.

Innohep FDA Prescribing Information: Side Effects
(Adverse Reactions)
SIDE EFFECTS
Bleeding: Bleeding is the most common adverse event associated with INNOHEP® (tinzaparin sodium injection); however, the incidence of major bleeding is low. In clinical trials, the definition of major bleeding included bleeding accompanied by ≥ 2 gram/dL decrease in hemoglobin, requiring transfusion of 2 or more units of blood products, or bleeding which was intracranial, retroperitoneal, or into a major prosthetic joint. The data are provided in Table 4.
Table 4 : Major Bleeding Events1 in Treatment of Acute Deep
Vein Thrombosis With or Without Pulmonary Embolism
| Indication | Treatment Group1 | |
| Treatment of Acute DVT With or Without PE | INNOHEP® (tinzaparin) N=519 % |
Heparin N=524 % |
| Major Bleeding Events2 | 0.83 | 2.73 |
| 1 INNOHEP® (tinzaparin) 175 IU/kg once
daily SC. Unfractionated heparin initial IV bolus of 5,000 IU followed
by continuous IV infusion adjusted to an aPTT of 1.5 to 2.5 or initial
IV bolus of 50 IU/kg followed by continuous IV infusion adjusted to an
aPTT of 2.0 to 3.0. In all groups treatment continued for approximately
6 to 8 days, and all patients received oral anticoagulant treatment commencing
in the first 2 to 3 days. 2 Bleeding accompanied by ≥ 2 gram/dL decline in hemoglobin, requiring transfusion of or more units of blood products, or bleeding which was intracranial, retroperitoneal, or into a major prosthetic joint. 3 The 95% CI on the difference in major bleeding event rates (1.9%) was 0.33%, 3.47%. |

Fatal or nonfatal hemorrhage from any tissue or organ can occur. The signs, symptoms, and severity will vary according to the location and degree or extent of the bleeding. Hemorrhagic complications may present as, but are not limited to, paralysis; paresthesia; headache, chest, abdomen, joint, muscle or other pain; dizziness; shortness of breath, difficult breathing or swallowing; swelling; weakness; hypotension, shock, or coma. Therefore, the possibility of hemorrhage should be considered in evaluating the condition of any anticoagulated patient with complaints which do not indicate an obvious diagnosis (see WARNINGS, Hemorrhage).
Thrombocytopenia
In clinical studies thrombocytopenia was identified in 1% of patients treated with INNOHEP® (tinzaparin) . Severe thrombocytopenia (platelet count < 50,000/mm³) occurred in 0.13% (see WARNINGS, Thrombocytopenia).
Elevations of Serum Aminotransferases
Asymptomatic increases in aspartate (AST [SGOT]) and/or alanine (ALT [SGPT]) aminotransferase levels greater than 3 times the upper limit of normal of the laboratory reference range have been reported in up to 8.8% and 13% for AST and ALT, respectively, of patients receiving tinzaparin sodium for the treatment of DVT. Similar increases in aminotransferase levels have also been observed in patients and healthy volunteers treated with heparin and other low molecular weight heparins. Such elevations are reversible and are rarely associated with increases in bilirubin (see PRECAUTIONS, Laboratory Tests).
Local Reactions
Mild local irritation, pain, hematoma, and ecchymosis may follow SC injection of INNOHEP® (tinzaparin) . Injection site hematoma has been reported in approximately 16% of patients treated with INNOHEP® (tinzaparin) .
Hypersensitivity
Anaphylactic/anaphylactoid reactions may occur in association with INNOHEP® use (see CONTRAINDICATIONS and WARNINGS).
Adverse Events
Adverse events with INNOHEP® (tinzaparin) or heparin reported at a frequency of ≥ 1% in clinical trials with patients undergoing treatment for proximal DVT with or without PE, are provided in Table 5.

Ongoing Safety Surveillance
When neuraxial anesthesia (epidural/spinal anesthesia) or spinal puncture is employed, patients anticoagulated or scheduled to be anticoagulated with low molecular weight heparins or heparinoids for prevention of thromboembolic complications are at risk of developing an epidural or spinal hematoma which can result in long-term or permanent paralysis (see BOXED WARNING).
Spinal epidural hematoma in association with neuraxial anesthesia or spinal puncture with INNOHEP (tinzaparin) ® has been reported.
Spinal epidural hematoma with INNOHEP® (tinzaparin) administered at a therapeutic dose has been reported in at least one patient who had not received neuraxial anesthesia or spinal puncture.
