What does it do?

Dalteparin is used to treat and help prevent clots in your blood.

Before you start

• Tell your doctor if you have bleeding or kidney problems.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you use it?

Inject dalteparin under the skin regularly as directed. You can use your stomach or thighs. Change the place you inject each time. Do not rub the injection site as this may cause bruising.
You, or the person giving the injections, will be given training on how to use the injections.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and inject your next dose at the usual time. Otherwise, inject the missed dose as soon as possible. Do not inject two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with dalteparin including:

• anti-inflammatories, such as diclofenac (e.g. Voltaren®), ibuprofen (e.g. Nurofen®), or aspirin (e.g. Disprin®, in doses used for pain relief). These can also be found in some cold and flu medicines (e.g. Nurofen Cold and Flu®).
• low-dose aspirin (e.g. Cartia®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
