Uses For danaparoid
Danaparoid 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. Danaparoid is used for several days after hip replacement surgery, while you are unable to walk. It is during this time that blood clots are most likely to form. Danaparoid also may be used for other conditions as determined by your doctor.
Danaparoid was available only with your doctor's prescription.
Organon, Inc. discontinued manufacturing Orgaran® (danaparoid) on August 14, 2002 .
Before Using danaparoid
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 danaparoid, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to danaparoid or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Studies on danaparoid have been done only in adult patients, and there is no specific information comparing use of danaparoid in children with use in other age groups.

Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of danaparoid in the elderly with use in other age groups.
