What pregnancy precautions are required with bosentan?
People who can become pregnant must use reliable contraception and follow a pregnancy-testing schedule before and during treatment to ensure pregnancy does not occur while taking bosentan. If pregnancy is suspected, dosing should be stopped and urgent medical advice is needed.

If bosentan was taken during pregnancy (even before a pregnancy was recognized), contacting a clinician immediately is important. The key action is prompt medical guidance on stopping the drug and evaluating the pregnancy given the known fetal risk.
