What does it do?

Tinzaparin is used to treat and prevent clots in your blood.

Before you start

• Tell your doctor if you have bleeding, kidney, liver or stomach problems, have a history of high blood pressure or stroke, or have recently had surgery or any injuries.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you use it?

Inject tinzaparin under the skin regularly as directed. Do not rub the injection site as this may worsen any bruising.

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 tinzaparin 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.
