Direct thrombin inhibitor (anticoagulant)

Argatroban (أرجاتروبان)

Argatroban is an anticoagulant given as an infusion into a vein in hospital. It is mainly used when heparin has caused a dangerous fall in platelets with a risk of clots, and it needs frequent blood tests to adjust the dose.

This medicine is used under close medical supervision, usually by a specialist. Never start, stop or change it without your doctor.

What it is used for

  • Preventing and treating blood clots in people with heparin-induced thrombocytopenia
  • Preventing clotting during heart catheter procedures in people who have or are at risk of heparin-induced thrombocytopenia

How it is used

  • It is given as an infusion into a vein by medical staff in hospital only
  • The doctor sets and adjusts the dose using frequent clotting tests and liver function
  • When switching to an anticoagulant by mouth, the doctor follows the tests closely because argatroban affects their results

Possible side effects

  • Bleeding such as from the gums or nose, bruising, or blood in the urine or stools
  • Nausea or vomiting
  • Low blood pressure
  • Rarely, allergy such as a rash or breathlessness

Who should not use it

  • Active major bleeding
  • Allergy to argatroban or any ingredient of the product

Before and while using it

  • Tell the medical staff at once about any bleeding, sudden severe headache, black stools or vomiting blood
  • People with liver disease need a lower dose and closer monitoring
  • Tell the doctor if you have very high blood pressure, recent surgery or injury, or a stomach ulcer
  • Heparin in any form should not be given to someone with heparin-induced thrombocytopenia unless a specialist decides

Medicine interactions

  • Other anticoagulants and clot-dissolving medicines increase bleeding risk
  • Aspirin, antiplatelet medicines and anti-inflammatory painkillers increase bleeding risk
  • Warfarin with argatroban raises the INR result, so switching between them follows a careful plan

Pregnancy and breastfeeding

  • Tell your doctor if you are pregnant; information is limited and it is used only when the benefit is clear
  • Breastfeeding is not advised during treatment unless discussed with the doctor

How to store it

  • Hospital staff store it as the leaflet directs, protected from light and not frozen

Get medical help straight away if

  • Your face, lips or tongue swell, or you find it hard to breathe.
  • You get a severe rash, blistering or peeling skin.
  • A side effect worries you or doesn’t go away: contact your doctor or pharmacist.
