About your treatment

Your doctor has ordered dalteparin sodium, an anticoagulant ('blood thinner'), to prevent harmful blood clots from forming. The drug will be injected under the skin (subcutaneously) once a day. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Your health care provider (doctor, nurse, or pharmacist) may measure the effectiveness and side effects of your treatment using laboratory tests and physical examinations. It is important to keep all appointments with your doctor and the laboratory. The length of treatment depends on how you respond to the medication.

Precautions

Before administering dalteparin:

• tell your doctor and pharmacist if you are allergic to dalteparin, heparin, enoxaparin (Lovenox), any other drugs, or pork products.
• tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially those listed in the IMPORTANT WARNING section and vitamins.
• tell your doctor if you have or have ever had liver or kidney disease or diabetes.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking dalteparin, call your doctor.

Administering your medication

Before you administer dalteparin, look at the solution closely. It should be clear and free of floating material. Observe the solution container to make sure there are no leaks. Do not use the solution if it is discolored, if it contains particles, or if the container leaks. Use a new solution, but show the damaged one to your health care provider.

It is important that you use your medication exactly as directed. Do not change your dosing schedule without talking to your health care provider.
