Fragmin (Dalteparin) is a type of medication called a low-molecular-weight Heparin. It belongs to a class of medications called anticoagulants or antithrombotic agents. It helps prevent Blood Clots from forming or from getting bigger, but it does not dissolve existing blood clots.

Fragmin (Dalteparin) works by blocking clotting factors and enzymes that help the blood to clot. Circulating blood clots are dangerous because they can cause medical problems such as Heart Attack, Stroke, and pulmonary Embolism.

Fragmin (Dalteparin) is used to treat blood clots in deep veins (deep vein thrombosis), treat people with unstable Coronary Artery Disease, and to treat symptoms of blood clots in order to prevent the recurrence of blood clots in people with cancer.

Fragmin (Dalteparin) is also used to prevent blood clots during surgery, blood dialysis associated with Kidney Disease, and for people who are at risk for blood clots because of being bedridden due to illness.

Fragmin (Dalteparin) may be available under multiple brand names and/or in several different forms. Any specific brand name of Fragmin (Dalteparin) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Fragmin (Dalteparin) may not be used for all of the conditions discussed here.

Your doctor may have suggested Fragmin (Dalteparin) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using Fragmin (Dalteparin), speak to your doctor. Do not stop using Fragmin (Dalteparin) without consulting your doctor.

Do not give Fragmin (Dalteparin) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use Fragmin (Dalteparin) if their doctor has not prescribed it.

Fragmin (Dalteparin) is given by subcutaneous (under the skin) injection, usually in the lower abdominal area. Sometimes, in a hospital setting, Fragmin (Dalteparin) is given intravenously (into the vein). The recommended dose and route of administration of Fragmin (Dalteparin) varies according to the individual and the condition being treated. Your doctor will order blood tests to determine how effective the medication is for you and will adjust the dose based on the effect of Fragmin (Dalteparin).

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.

If you are injecting the medication yourself, your doctor or health care professional will show you how to inject the medication properly. If you have any questions about how to use your medication, contact your doctor or health care professional.

Medications other than those listed above may interact with Fragmin (Dalteparin). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Fragmin (Dalteparin).

Bleeding: The most serious risk associated with Fragmin (Dalteparin) is bleeding in any tissue or organ. It is extremely important to have regular blood tests as recommended by your doctor to ensure proper levels of clotting.

If you experience bleeding gums, bleeding from the mouth, bleeding from the anus or vagina, or you notice blood in your urine, contact your doctor as soon as possible. If you have an increased risk of bleeding you should be closely monitored by your doctors while taking Fragmin (Dalteparin).

Blood counts: While you are taking Fragmin (Dalteparin), your doctor will also be monitoring your blood cell counts, including a platelet count. If your platelet level drops very suddenly, you may have to stop Fragmin (Dalteparin) and switch to another type of medication. Make sure to tell your doctor if you have had any problems with low platelets or platelet defects in the past.

Body weight: The safety and effectiveness of Fragmin (Dalteparin) for people of high weight (e.g., over 120 kg) and low weight (e.g., under 46 kg) have not been fully established. If you have a high or low body weight, discuss with your doctor how Fragmin (Dalteparin) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fragmin (Dalteparin), and whether any special monitoring is needed.

Heart problems: Blood clots have occurred for people with prosthetic heart valves using low molecular weight heparins. People with unstable coronary artery disease may be at increased risk of bleeding. If you have a history of heart disease or have prosthetic heart valves your doctor should closely monitor your condition while you are taking Fragmin (Dalteparin).

Kidney problems: The kidneys remove much of Fragmin (Dalteparin) from your body. People with decreased kidney function or kidney disease may experience increased side effects of Fragmin (Dalteparin) as a result of the medication building up in the body. If you have reduced kidney function or kidney disease, discuss with your doctor how Fragmin (Dalteparin) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fragmin (Dalteparin), and whether any special monitoring is needed.

Liver problems: People with liver problems may be at an increased risk for bleeding. If you have decreased liver function or liver disease, discuss with your doctor how Fragmin (Dalteparin) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fragmin (Dalteparin), and whether any special monitoring is needed.

Osteoporosis: Other medications in the heparin family have been reported to encourage the development of osteoporosis. If you have osteoporosis or are at risk for developing osteoporosis, discuss with your doctor how Fragmin (Dalteparin) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fragmin (Dalteparin), and whether any special monitoring is needed.

Potassium levels: Increases in blood levels of potassium occur for a small percentage of people taking medications in the heparin family, including Fragmin (Dalteparin). This may be more likely to happen if you have diabetes or chronic kidney failure, or if you are taking potassium sparing diuretics. Your doctor may want to monitor your potassium levels. If you experience unexplained nausea, fatigue, muscle weakness, or tingling sensations, contact your doctor.

Stomach or intestinal ulcers: Fragmin (Dalteparin) increases the risk of unwanted bleeding. If you have a history of stomach or intestinal ulcers, discuss with your doctor how Fragmin (Dalteparin) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fragmin (Dalteparin), and whether any special monitoring is needed. People with active stomach or intestinal ulcers should not use Fragmin (Dalteparin).

Surgery: The risk of bleeding while using low molecular weight heparin may be greater in knee surgery than other orthopedic surgeries. Your doctor will weigh the potential risks and benefits to decide whether low molecular weight heparins will be used during surgery.

There have been cases of spinal bleeding and blood clots when Fragmin (Dalteparin) is used along with spinal or epidural anesthesia. These spinal blood clots may lead to long-term or permanent paralysis. The risk is greater with higher treatment doses of Fragmin (Dalteparin) than with deep vein thrombosis prevention doses. The risk is also greater for people who are taking other medications that affect blood such as Naproxen or Ibuprofen, or other anticoagulants. If you notice a sudden inability to move your body or sudden back pain or tenderness, get medical help immediately.

Pregnancy: Fragmin (Dalteparin) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Fragmin (Dalteparin), contact your doctor immediately.

If you do use Fragmin (Dalteparin) while you are pregnant, your doctor should closely monitor you because of an increased risk of bleeding. Pregnant women who have artificial heart valves also need to be closely monitored by their doctors if they use Fragmin (Dalteparin) because of a higher risk of developing clots in their heart valves.

Pregnant women should not use Fragmin (Dalteparin) from multidose vials containing benzyl alcohol as a preservative.

Breast-feeding: It is not known if Fragmin (Dalteparin) passes into breast milk. If you are a breast-feeding mother and are taking Fragmin (Dalteparin), it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using Fragmin (Dalteparin) have not been established for children.

Seniors: Seniors may be at an increased risk of bleeding while using Fragmin (Dalteparin). Your doctor may adjust your dose, especially if you weigh less than 45 kg or have decreased kidney function.
