Trends in conceptions before and after the 1995 pill scare

Area of Science:

• Reproductive Health
• Public Health
• Pharmacovigilance

Background:

• In October 1995, a safety warning was issued regarding specific oral contraceptives containing new-generation progestogens.
• The warning highlighted a potentially increased risk of thrombosis (blood clot formation) associated with these contraceptive pills.
• Media attention and public health concerns arose regarding the potential impact of this warning on contraceptive use and pregnancy rates.

Purpose of the Study:

• To investigate the impact of the 1995 'pill scare' on national conception rates.
• To analyze trends in unplanned pregnancies before and after the media-driven warning about oral contraceptives.

Main Methods:

• Utilized national conception statistics for trend analysis.
• Compared conception data from periods preceding and succeeding October 1995.

Main Results:

• Analysis of national conception statistics showed no significant increase in unplanned pregnancies after the warning.
• Contraceptive pill usage trends and their correlation with conception rates were examined in the context of the safety alert.

Conclusions:

• The public health concerns regarding a rise in unplanned pregnancies due to the contraceptive pill scare were not substantiated by national conception data.
• This study provides evidence that the impact of the 1995 safety warning on contraceptive behavior and subsequent pregnancy rates was minimal.
