Generic Name: tinzaparin (TIN-za-PAR-in)
Brand Name: Innohep
Tell your doctor you use tinzaparin before you have any type of spinal puncture or epidural/spinal anesthesia. Patients who have these procedures while they use tinzaparin are at risk for developing a blood clot on or near the spinal cord. This could result in long-term or permanent paralysis.
The risk is increased in patients who have an indwelling epidural catheter, traumatic or repeated epidural or spinal puncture, or a history of a deformed spine or spinal surgery, and in patients who use medicines that may affect blood clotting, such as warfarin, aspirin, platelet inhibitors (eg, clopidogrel), and nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen, naproxen).
If you have a spinal puncture or epidural/spinal anesthesia while you use tinzaparin, tell your doctor immediately if you notice any signs or symptoms of nerve problems, such as numbness or tingling, muscle weakness, or paralysis.
Tinzaparin is used for:
Preventing blood clots in patients who will be having certain types of surgery. It is also used to treat certain types of blood clots (deep vein thrombosis, pulmonary embolism). It is also used to prevent blood from clotting in dialysis lines. It may also be used for other conditions as determined by your doctor.
Tinzaparin is a low molecular weight heparin (LMWH). It works by blocking the formation of blood clots.
Do NOT use tinzaparin if:
- you are allergic to any ingredient in tinzaparin or to heparin or other similar medicines (eg, enoxaparin)
- you have uncontrolled, severe high blood pressure; eye problems caused by diabetes (diabetic retinopathy) or bleeding (hemorrhagic retinopathy); or a bacterial infection of the heart (endocarditis)
- you have hemophilia, blood clotting problems that increase your risk of bleeding, or active bleeding (eg, bleeding ulcer)
- you bleed easily or have conditions or diseases with high risk of bleeding (eg, severe liver problems, an abortion with a large amount of vaginal bleeding)
- you have a history of low blood platelets or bleeding problems due to the use of heparin (heparin-induced thrombocytopenia)
- you have recently had a stroke, or an injury or surgery involving the brain, spinal cord, eyes, or ears
- you are older than 70 years old and have kidney problems
