What Nplate is used for

Nplate is used to treat low blood platelet counts in people with immune (idiopathic) thrombocytopenic purpura (called ITP). ITP is a disease in which your immune system destroys your platelets.
Platelets are the cells in your blood that help seal cuts and form blood clots. If you have too few platelets you could bruise more easily than normal. You could also bleed for a long time after being injured. If your platelet count is very low, you may be at risk of serious, life-threatening bleeding.
This medicine works by increasing the number of platelets made by your body. Nplate makes your bone marrow produce more platelets. This helps to prevent bruising and bleeding.
Your doctor, however, may prescribe Nplate for another purpose.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
This medicine is available only with a doctor's prescription.

Taking other medicines

How it is given

Nplate is given as an injection under the skin. This is called a subcutaneous injection.
Follow all directions given to you by your doctor, nurse or pharmacist carefully.
They may differ from the information contained in this leaflet.

How much is given

When you first start using Nplate your dose is 1 microgram per kilogram of your body weight, given once a week.
Your doctor will determine how much to inject.
Your doctor will adjust your dose of Nplate depending on your blood platelet count.

When to use it

Nplate is injected once per week to keep your platelet counts in a safe range.

How long to use it

Continue using your medicine for as long as your doctor tells you.
This medicine helps control your condition, but does not cure it.

If you miss a dose

If you miss a dose, talk to your doctor.

If you are given too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 131126) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Nplate.
Do this even if there are no signs of discomfort or poisoning.
