Overview

• The study analyzed data from over 261,000 women with asthma using contraceptive pills and 127,000 controls between 2004 and 2020.
• Women under 35 on the progesterone-only pill had a 39% higher risk of asthma attacks compared to non-users, while no increased risk was found for combined pills.
• A subgroup of women on fewer asthma treatments showed a 20% increased risk of attacks when using the mini pill.
• Findings for women with eosinophilic asthma indicated a potential 24% increased risk, though this was not statistically significant.
• Experts emphasize the preliminary nature of the research and advise against altering prescribing practices until further studies are conducted.
