PH and pregnancy

PH and pregnancy

Pregnancy poses a risk for women with any type of pulmonary hypertension (PH) as it is associated with high rates of maternal illness and even death.1 For this reason, women of childbearing age with PH are recommended to use reliable contraceptive methods to avoid pregnancy, or to consider an early termination if they do get pregnant.2


Various methods of contraception are available – some can be used alone, whereas others should be used together to ensure sufficient protection from pregnancy.3,4

It is important for women with PH to be informed and aware of the risks of pregnancy, and for them to seek expert advice from a women’s health specialist, alongside their PH specialist, when deciding on the most suitable method of contraception for them.
