What clinical scenario describes a Category 3 situation for combined oral contraceptive use?

The correct scenario for a Category 3 situation for combined oral contraceptive (COC) use is associated with the history of Roux-en-Y gastric bypass surgery. In this context, Category 3 indicates that the theoretical or proven risks usually outweigh the advantages of using the method. Patients who have undergone Roux-en-Y gastric bypass surgery may have altered absorption of medications, including hormones present in combined oral contraceptives. This can lead to potential concerns regarding contraceptive efficacy, as weight loss and changes in gastrointestinal physiology may impact how the hormones are metabolized and absorbed.

In this case, the consideration rests on the understanding that while COCs may still be used, close monitoring and additional contraceptive methods may be recommended due to the uncertainty of the effectiveness resulting from surgery-related changes. This highlights the need for practitioners to be aware of individual patient history and its implications on contraceptive management.
