Dalteparin is used to treat and prevent harmful blood clots. Preventing harmful blood clots helps to reduce the risk of a stroke or heart attack. This medication helps keep your blood flowing smoothly by lowering the activity of clotting proteins in the blood. Dalteparin is a type of heparin, and works as an anticoagulant (commonly called a "blood thinner").

Conditions that increase your risk of developing blood clots include certain types of surgeries (such as hip replacement or abdominal surgery), long periods of being in one position (immobile), certain types of heart attack, and a certain type of chest pain called unstable angina. For some medical conditions, dalteparin may be used in combination with other "blood thinners." Dalteparin may also be used to treat and prevent clots from coming back in patients with cancer.

Read the Patient Information Leaflet if available from your pharmacist before you start using dalteparin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

This medication is given by injection under the skin as directed by your doctor, usually once or twice daily. Do not inject into a muscle. The dosage and length of treatment are based on your medical condition and response to treatment. The dosage may also be based on your weight for some conditions.

If you are using this medication at home, learn all preparation and usage instructions from your health care professional and the product package. You should be lying down or sitting when you inject yourself. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. This medication should not be mixed with or added to any other medication in the same syringe. 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.

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.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: serious active bleeding, artificial heart valves, bleeding or blood disorders (low platelet counts), certain eye problems (hypertensive or diabetic retinopathy), high blood pressure, infection of the heart, kidney disease, liver disease, low platelet counts after previous heparin treatment, certain stomach/intestinal problems (such as active or recent ulcers), stroke, recent spinal procedures or puncture, spine problems (such as spinal deformity), recent eye/brain/spinal cord surgery.

Limit alcohol while taking this drug because it may increase the risk of stomach bleeding.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

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.

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. Pregnant women with artificial heart valves need close monitoring (see Notes).

This medication passes into breast milk. Consult your doctor before breast-feeding.

Store at room temperature away from light and moisture. Do not store in the bathroom. Keep all medications away from children and pets.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist.

One product that may interact with this drug is: mifepristone.

This medication is sometimes used together with other drugs that have "blood thinning" or anti-platelet effects such as aspirin, clopidogrel, or warfarin. When these combinations are prescribed by your doctor, you will require closer monitoring to minimize your risk of bleeding. Keep all medical and laboratory appointments.

Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (NSAIDs such as ibuprofen, naproxen, or aspirin) which can increase the risk of bleeding/anti-platelet effect when used with dalteparin. However, if your doctor has directed you to take low-dose aspirin for heart attack or stroke prevention (usually at dosages of 81-325 milligrams a day), you should continue taking it unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.

If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away.

Laboratory and/or medical tests (such as blood counts including hemoglobin, hematocrit and platelets, checking stool for blood) should be performed periodically to monitor your progress or check for side effects. Additional lab tests (anti-factor Xa blood levels) should be performed in certain cases, especially if you have kidney disease, are pregnant and have artificial heart valves, or to check if dalteparin is working well for you. Consult your doctor for more details.
