What should I discuss with my healthcare provider before using dalteparin (Fragmin)?
You should not use this medication if you are allergic to dalteparin, heparin, or pork products, or if you have:
Dalteparin may cause you to bleed more easily, especially if you have:
Dalteparin can cause a very serious blood clot around your brain or spinal cord if you undergo a spinal tap or receive spinal anesthesia (epidural). This type of blood clot could cause long-term paralysis, and may be more likely to occur if you have:
To make sure you can safely use dalteparin, tell your doctor if you have other medical conditions, especially:
FDA pregnancy category B. Dalteparin is not expected to harm an unborn baby. However, some forms of this medication contain a preservative that may be harmful to a newborn. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether dalteparin passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
How should I use dalteparin (Fragmin)?
Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. When used for DVT or blood vessel complications, dalteparin is usually given every day until your bleeding condition improves. When used for VTE, dalteparin is often used for several months. Follow the directions on your prescription label.
Dalteparin is injected under the skin. You may be shown how to use injections at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes.
Do not mix dalteparin with other medications in the same syringe unless your doctor tells you to.
Prepare your dose in a syringe only when you are ready to give yourself an injection. Do not use the medication if it has changed colors or has particles in it. Call your doctor for a new prescription.
You should be sitting or lying down during the injection. Do not inject dalteparin into a muscle.
Use a different place on your stomach each time you give the injection. Your care provider will show you the best places on your body to inject the medication. Do not inject into the same place two times in a row.
If you use a single-dose prefilled syringe, follow the injection instructions closely. Single-dose syringes come in two different types and the directions for use are not the same for each type.
Use a disposable needle only once. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.
Tell any doctor who treats you that you are using dalteparin. If you need surgery or dental work, tell the surgeon or dentist ahead of time that you are using this medication. If you need anesthesia for a medical procedure or surgery, you may need to stop using dalteparin for a short time.
To be sure this medication is not causing harmful effects, your blood and your stool (bowel movement) may need to be tested often. Your nerve and muscle function may also need to be tested. Visit your doctor regularly.
Store dalteparin vials (bottles) at room temperature away from moisture and heat. Once you have used a vial for the first time, the medicine will keep at room temperature for up to 2 weeks. Throw away the vial after 2 weeks have passed since you first used the vial, even if there is still medicine left in it.
