Emergency asthma medication 'could make it harder for women to conceive'

Women who only use an inhaler to alleviate the symptoms of an asthma attack rather than taking long-term medication could find it more difficult to conceive, according to new research.

A study of 5,000 women in Australia, New Zealand, the UK and Ireland found those who only used their inhaler in an emergency rather than taking it to prevent an attack took longer to get pregnant.
