A French study recently showed that a medication identical to Plan B, marketed as the morning-after pill, is less effective in women who are overweight. The research indicated that medication begins to lose effectiveness in women over 165 pounds, and is completely ineffective in women over 176 pounds.

Alison Edelman, M.D., MPH, joins “Sound Medicine” to discuss the “morning after pill,” the effectiveness of Plan B, and what types of contraceptives are best for heavier women. Dr. Edelman is an associate professor in the Department of Obstetrics and Gynecology at Oregon Health & Science University.
