Pros and cons of Fragmin (dalteparin)
Pros
- Approved for extended (6 month) treatment of blood clots in people with cancer
- Can be used in children age 1 month or older
- Doesn’t usually need to be monitored with blood tests
- In cases of overdose or dangerous bleeding, there is an antidote called protamine that can reverse the effects of Fragmin (dalteparin).
- Doesn't interact with food like warfarin (Coumadin) does
Cons
- It's a low-molecular weight heparin, which means you can’t use it if you’ve had heparin-induced thrombocytopenia (HIT).
- Brand name only, and can be more expensive than similar medications like enoxaparin (Lovenox)
- Not a first-choice medication for people with kidney problems
- Can interact with NSAIDs, such as ibuprofen (Advil, Motrin) and naproxen (Aleve), and raise bleeding risk
- Some people will need to inject the medication multiple times a day
Pharmacist tips for Fragmin (dalteparin)
- Talk to your provider or pharmacist to make sure you understand how to inject this medication the correct way before you start it at home. It's important that you get the right amount of medication.
- People with latex allergies should avoid touching the prefilled Fragmin (dalteparin) syringe. The needle shield may contain rubber latex.
- Check the solution in the syringe to make sure it hasn't changed colors and doesn't have particles in it. For the fixed-dose syringe, air bubbles are okay, don't push them out before using the syringe or you might lose some medication.
- Store the syringes at room temperature. If you're using the vial, you can store it at room temperature for up to 2 weeks.
- The medication must be injected into your fatty tissue and not your muscle. You can inject it into your lower abdomen around your belly button, the upper outter side of your thigh, or certain parts of your butt. Rotate your injeciton site every day to avoid unwanted side effects.
- Make sure all your providers know you are taking Fragmin (dalteparin), especially surgeons and dentists. Fragmin (dalteparin) can make you bleed more, so they might tell you to stop taking the medication for a short period of time if you are having a procedure done.
- Let your provider know right away if you see any blood in your stool or urine, cough up or vomit blood, or have any bleeding that doesn’t stop.
Common questions about Fragmin
Fragmin belongs to a class of anticoagulants called low molecular weight heparins (LMWH). It works similar to heparin because it thins your blood to prevent blood clots. Since it's a LMWH, it has a different structure so it targets a more specific type of clotting protein. When given as a subcutaneous (under the skin) injection, Fragmin is absorbed better, lasts longer, and requires fewer injections per day.
It's usually recommended to avoid NSAID medications, like aspirin, because they can raise your risk of serious bleeding when taken with Fragmin. However, people who are taking Fragmin for unstable angina or NSTEMI, should continue to take aspirin and other heart medications. As always, talk to your provider before starting or stopping any medications.
If you are injecting Fragmin once a day, it can be injected at any time of the day, but it's important to do it at the same time every day. This will keep the amount of medication in your body at the right level.
No, Fragmin doesn't affect PT or INR, which are the lab values that are typically monitored for people taking heparin or warfarin. Fragmin works on a specific protein called factor Xa and can be monitored with anti-Xa levels. Fragmin isn't usually monitored except in certain high risk people, such as children, pregnant women, and people with kidney problems. Anti-Xa levels allow providers to make sure you're getting the right dose.
Some people with no major medical problems can have a drink once in a while, but first check with your provider. Keep in mind, however, that Fragmin can raise your risk of bleeding, which can be extremely dangerous if you fall or hit your head while drinking. Before drinking alcohol, talk with your provider to make sure it's safe for you.
About 5 out of 100 people in clinical studies reported having pain at the Fragmin injection site. Rotate the site where you inject Fragmin each time to help prevent pain and bruising.

Risks and warnings for Fragmin (dalteparin)
Fragmin (dalteparin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Bleeding around the spinal cord
- Risk factors: Spinal puncture (spinal tap) | Getting anesthesia near the spine (epidural anesthesia) | History of spinal surgery | Also using nonsteroidal anti-inflammatory drugs (NSAIDs) or other blood thinners
If you're taking Fragmin (dalteparin) and are getting either a spinal tap or an epidural, you're at a greater risk of bleeding around your spinal cord, which can make you paralyzed. Your provider will tell you how to stop taking Fragmin (dalteparin) safely before you go through a back surgery or procedure. Call your provider right away if you notice pain, tingling, a burning sensation, numbness, weakness, or are unable to urinate.
Low platelet counts and clotting problems
- Risk factors: History of heparin-induced thrombocytopenia (HIT)
Fragmin (dalteparin) can cause your platelet counts to go down, and in rare cases, can cause a life-threatening condition called heparin-induced thrombocytopenia (HIT). HIT happens when the immune system creates antibodies that affect the function of platelets, causing blood clots to form in various parts of the body. If your platelets become very low, it's likely that Fragmin (dalteparin) will be stopped and your providers will consider a different blood thinner for you if needed.
