GENERIC NAME: TINZAPARIN - INJECTION (TIN-za-PAR-in)
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.
USES: Tinzaparin is used to treat serious blood clots, usually in the legs. Tinzaparin may also be used to treat blood clots in the lungs. It is usually used with another "blood thinner" medication (warfarin). If untreated, blood clots can travel to the lungs, heart, or brain, causing serious (possibly fatal) breathing problems, heart attack, or stroke.This drug may also be used to prevent blood clots after certain surgeries with an increased risk of blood clots (such as knee or hip replacement). It may also be used to prevent clotting in certain catheters used by patients on hemodialysis.Tinzaparin is known as a "blood thinner" (anticoagulant). It is a type of heparin called low-molecular-weight heparin. It works by blocking certain natural substances in the blood that cause clotting.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start using tinzaparin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.You should be lying down or sitting when you inject yourself. Inject this medication under the skin of the stomach/abdomen, as directed by your doctor, usually once daily. Do not inject into a muscle. The dosage and length of treatment are based on your medical condition, weight, and response to treatment. Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each day.If you are using this medication at home, learn all preparation and usage instructions from your health care professional and the product package. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Do not mix any other medication in the same injection. Before injecting each dose, clean the injection site with rubbing alcohol. Change the injection site each time to lessen injury under the skin. To minimize bruising, do not rub the injection site after a shot. Learn how to store and discard medical supplies safely.When treating a blood clot, another "blood thinner" (warfarin) is usually started 1 to 3 days after you start using tinzaparin. Your doctor will direct you to use both of these medications until the warfarin is working well. Do not stop either of these medications until your doctor directs you to stop.To prevent blood clots due to surgery, your doctor may direct you to start using this medication before or after surgery and continue for several days. Follow your doctor's directions closely.This medication may also be given by injection into a vein (to prevent clotting of certain hemodialysis catheters) by a health care professional as directed by your doctor.
SIDE EFFECTS: Pain, bruising, redness, and swelling at the injection site may occur. Headache, nosebleed, and fever may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects.

This product may contain inactive ingredients (such as sulfites, benzyl alcohol), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using tinzaparin, tell your doctor or pharmacist your medical history, especially of: a past blood-clotting problem because of heparin (heparin-induced thrombocytopenia), artificial heart valves, bleeding/blood problems (such as low platelet count, bleeding ulcer), a certain eye problem (diabetic retinopathy), high blood pressure, infections in the heart (bacterial endocarditis), kidney disease, liver disease, stomach/intestinal problems (such as recent ulcers, colitis), stroke, recent spinal procedures or puncture, spine problems (such as spinal deformity), recent surgery (especially on the eye, brain, or spine).Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Limit alcohol while taking this drug because it may increase the risk of stomach bleeding.To lower the chance of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports.Older adults may be more sensitive to the side effects of this drug, especially bleeding. If you are elderly and have kidney problems, your doctor may stop tinzaparin and prescribe a different medication for your condition. Consult your doctor for more details.During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. If you become pregnant or think you may be pregnant, tell your doctor immediately.
