What is the most important information I should know about tinzaparin (Innohep)?
You should not use this medication if you are allergic to tinzaparin, heparin, sulfites, benzyl alcohol, or pork products, or if you have active bleeding or a history of low platelet counts after receiving heparin.
Tell any doctor who treats you that you are using tinzaparin. If you need anesthesia for a medical procedure or surgery, you may need to stop using the medicine for a short time.
Tinzaparin may cause you to bleed more easily, especially if you have: a bleeding disorder, hemorrhagic stroke, an infection in the lining of your heart, uncontrolled high blood pressure, stomach or intestinal bleeding or ulcer, kidney disease, liver failure, amyloidosis (a build-up of certain proteins in tissues and organs of the body), or if you have had recent brain, spine, or eye surgery.
Tinzaparin can cause a very serious blood clot around your brain or spinal cord if you undergo a spinal tap or receive spinal anesthesia (epidural), especially if you have a genetic spinal defect, a history of spinal surgery or repeated spinal taps, or if you are using other medications to treat or prevent blood clots. Symptoms of this type of blood clot include numbness, tingling, muscle weakness, or loss of movement.
Blood clots around the brain or spinal cord may occur during a spinal tap or epidural if you are using tinzaparin with other drugs that can affect blood clotting, including aspirin, non-steroidal anti-inflammatory drugs (NSAIDs) such as Advil or Motrin, and any other medications to treat or prevent blood clots.
Many other drugs (including some over-the-counter medicines) can increase your risk of bleeding or life-threatening blood clots, and it is very important to tell your doctor about all medicines you have recently used.
Tell your caregivers at once if you have signs of bleeding such as black or bloody stools, coughing up blood, confusion, feeling like you might pass out, or any bleeding that will not stop.
