Expert advice

  • Bosentan controls the symptoms of pulmonary arterial hypertension but does not cure it. It may take 1-2 months or longer before you experience the full benefit of bosentan.
  • Do not stop taking bosentan suddenly even if you feel well as this may worsen your symptoms.
  • You may have to undergo regular blood test every month during the treatment to check for anemia (low hemoglobin) and liver function.
  • Do not drive or operate any tools or machines while using bosentan, as it may cause dizziness affecting your ability to drive and use machines.
  • While taking bosentan, women must use a highly effective form of birth control or two methods together (example, contraceptive pills plus barrier method) to prevent pregnancy during treatment.
