Dalteparin (dal-TE-pa-rin) is used to prevent deep venous thrombosis, a condition in which harmful blood clots form in the blood vessels of the legs. These blood clots can travel to the lungs and can become lodged in the blood vessels of the lungs, causing a condition called pulmonary embolism. Dalteparin is used for several days after abdominal surgery, while you are unable to walk. It is during this time that blood clots are most likely to form. Dalteparin also may be used for other conditions as determined by your doctor.

Dalteparin is available only with your doctor's prescription, in the following dosage form:

Parenteral
• Injection (U.S. and Canada)

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For dalteparin, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to dalteparin or heparin. Also tell your health care professional if you are allergic to any other substances, such as foods, especially pork or pork products, preservatives, or dyes.

Pregnancy—Dalteparin has not been studied in pregnant women. However, it has not been shown to cause birth defects or other problems in animals.

Breast-feeding—It is not known whether this medicine passes into breast milk. Although most medicines pass into breast milk in small amounts, many of them may be used safely while breast-feeding. Mothers who are using this medicine and who wish to breast-feed should discuss this with their doctor.

Children—Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of dalteparin in children with use in other age groups.

Older adults—This medicine has been tested and has not been shown to cause different side effects or problems in older people than it does in younger adults.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are using dalteparin, it is especially important that your health care professional know if you are taking any of the following:

• Aspirin or
• Inflammation or pain medicine, except narcotics, or
• Ticlopidine—Using any of these medicines together with dalteparin may increase the risk of bleeding

Other medical problems—The presence of other medical problems may affect the use of dalteparin. Make sure you tell your doctor if you have any other medical problems, especially:

• Bleeding problems or
• Eye problems caused by diabetes or high blood pressure or
• Heart infection or
• High blood pressure (hypertension) or
• Kidney disease or
• Liver disease or
• Stomach or intestinal ulcer (active) or
• Stroke—The risk of bleeding may be increased

• Also, tell your doctor if you have received dalteparin or heparin before and had a reaction to either of them called thrombocytopenia (a low platelet count in the blood), or if new blood clots formed while you were receiving the medicine.

• In addition, tell your doctor if you have recently had medical surgery. This may increase the risk of serious bleeding when you are taking dalteparin.

If you are using dalteparin at home, your health care professional will teach you how to inject yourself with the medicine. Be sure to follow the directions carefully. Check with your health care professional if you have any problems using the medicine.

Put used syringes in a puncture-resistant, disposable container, or dispose of them as directed by your health care professional.
