Brand Name: Nplate
What is romiplostim?
Romiplostim is a man-made form of a protein that increases production of platelets (blood-clotting cells) in your body.
Romiplostim is used to prevent bleeding episodes in people with chronic immune thrombocytopenic purpura (ITP), a bleeding condition caused by a lack of platelets in the blood.
Romiplostim is usually given after other medications have been tried without successful treatment of symptoms.
Romiplostim is not a cure for ITP and it will not make your platelet counts normal if you have this condition.
Romiplostim may also be used for purposes not listed in this medication guide.

Using romiplostim long-term can cause harmful effects on your bone marrow that may result in serious blood cell disorders. To be sure this medication is helping your condition and not causing harmful effects, your blood will need to be tested often.
It may take up to 4 weeks of before romiplostim is completely effective in preventing bleeding episodes. For best results, keep receiving the medication as directed. Talk with your doctor if you have any bruising or bleeding episodes after 4 weeks of treatment.
After you stop using romiplostim, your risk of bleeding may be even higher than it was before you started treatment. Be extra careful to avoid cuts or injury for at least 2 weeks after you stop using romiplostim. Your blood will need to be tested weekly during this time.
