Cessation of asthma medication in early pregnancy

Area of Science:

• Reproductive Health
• Pulmonology
• Pharmacology

Background:

• Asthma is a common chronic respiratory disease affecting women of reproductive age.
• Management of asthma during pregnancy requires careful consideration of maternal and fetal health.
• Understanding medication use patterns during pregnancy is crucial for optimizing care.

Purpose of the Study:

• To investigate alterations in asthma medication utilization among pregnant women.
• To quantify changes in the use of various asthma drug classes during gestation.

Main Methods:

• Retrospective cohort study using prescription claims data from 112,171 pregnant women in Tennessee Medicaid (1995-2001).
• Analysis of weekly asthma medication use, including inhaled corticosteroids, short-acting beta-agonists, and rescue corticosteroids.
• Generalized estimating equation analyses were employed to assess changes in medication use.

Main Results:

• A significant decrease (P < 0.0005) in overall asthma medication use was observed from 5 to 13 weeks of pregnancy.
• Prescription rates declined by 23% for inhaled corticosteroids, 13% for short-acting beta-agonists, and 54% for rescue corticosteroids during the first trimester.
• These reductions indicate a substantial shift in asthma pharmacotherapy early in pregnancy.

Conclusions:

• Asthma medication utilization across all categories decreased during early pregnancy.
• The most pronounced declines were noted for inhaled and rescue corticosteroids.
• Findings suggest pregnant women may alter their asthma treatment regimens in early gestation.
