About This Medication

What the Medication is Used For

HEMABATE STERILE SOLUTION is used to stop excessive bleeding in women who have just given birth, when bleeding is due to the uterus (womb) failing to return to its normal size, and who have not responded to conventional treatments.

What It Does

HEMABATE STERILE SOLUTION belongs to a group of medicines called prostaglandins that acts to increase the contractions of the uterus (womb). This helps to control bleeding after delivery.

When It Should not be Used

You should not be given HEMABATE STERILE SOLUTION if you:

  • are allergic to carboprost tromethamine or any of the other ingredients of HEMABATE STERILE SOLUTION, in particular benzyl alcohol.
  • have a heart, lung, kidney or liver disease.
  • have an infection of your uterus, ovaries or fallopian tubes.

What the Medicinal Ingredient Is

carboprost

What the Nonmedicinal Ingredients Are

Benzyl alchohol, sodium chloride, tromethamine, and water for injections. Small amounts of hydrochloric acid and sodium hydroxide (used to regulate the acidity or alkalinity of the solution) may also be present.

What Dosage Forms It Comes In

HEMABATE STERILE SOLUTION is available as a sterile solution contained in an ampoule. Each ml contains 250 micrograms of carboprost.

Warnings and Precautions

HEMABATE STERILE SOLUTION must be given only by a health care professional experienced in the use of the drug in hospitals or clinics with specialized units for pregnancy and childbirth.

HEMABATE STERILE SOLUTION may cause temporary high fever, and rarely, heart and blood circulation failure or airway constriction.

BEFORE you are given HEMABATE STERILE SOLUTION, talk to your doctor or pharmacist if you currently have, or have had in the past any of the following conditions:

  • lung disease, including asthma
  • high or low blood pressure (including high blood pressure in pregnancy)
  • heart disease or anaemia (low blood count)
  • kidney or liver disease (including jaundice)
  • glaucoma (raised pressure in your eyes)
  • diabetes or epilepsy
  • a caesarean section or any other operation on your womb

HEMABATE STERILE SOLUTION is not indicated for use in children. HEMABATE STERILE SOLUTION contains benzyl alcohol. Benzyl alcohol has been reported to be associated with a fatal "Gasping Syndrome" in premature infants.

Pregnancy

HEMABATE STERILE SOLUTION will only be given shortly after you have delivered your baby and not while you are still pregnant as it could put the embryo or foetus at risk.
