tinzaparin - injection


Warning | Medication Uses | How To Use | Side Effects | Precautions | Drug Interactions | Overdose | Notes | Missed Dose | Storage

WARNING: Tell your doctor if you use/have used tinzaparin before having any procedures involving puncture of the spine or needles left in the spine to give pain-blocking medication (including lumbar punctures, indwelling spinal/epidural catheters). Also, before starting tinzaparin, tell your doctor if you have had any of these procedures. Using this medication before/after these procedures has rarely caused severe bruising/bleeding in the spine (epidural/spinal hematoma). This effect may cause paralysis that may be permanent. Your doctor may try to decrease the risk of these side effects by having you stop the medication for a certain amount of time before and after the procedure. Follow your doctor's instructions carefully. Discuss the risks and benefits of treatment with your doctor. Get medical help right away if you have any of these serious side effects: back pain, tingling, weakness, numbness, or loss of control over your bladder or bowels. (See also Precautions section.)

This risk is increased the longer the needles are left in the spine or the more often these spinal puncture procedures are done. Using other "blood-thinning" or anti-platelet medications such as aspirin, clopidogrel, or warfarin, or nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen, also increases the risk. Tell your doctor if you are taking any of these medications. Do not stop taking any prescribed medication without first consulting your doctor. Your doctor will monitor you closely while you are using this medication.
