Exogenous estrogen or progesterone may positively or negatively impact a woman's asthma.


Sources of exogenous hormones:

(1) oral contraceptives

(2) postmenopausal hormone replacement


Some women will experience a reduction in asthmatic symptoms when receiving these agents. These patients may benefit from ongoing hormone replacement, especially if they have severe asthma or difficult-to-manage asthma.


Other women may experience worsening of asthma when receiving these agents. These patients may need to avoid these agents or use a reduced dose.


Oral contraceptive therapy may be beneficial for a woman experiencing pre-menstrual exacerbations of asthma by controlling the swing in hormone levels.
