What common side effect of estrogen in oral contraceptives should patients be educated about?

Nausea is a common side effect experienced by patients taking oral contraceptives that contain estrogen. This occurs because estrogen can affect the gastrointestinal tract and influence the brain's vomiting center, leading to sensations of nausea. Patients should be educated about this potential side effect, especially during the initial months of starting the contraceptive, as the body is adjusting to hormonal changes.

Although other side effects like weight gain, headaches, and acne can also occur with oral contraceptives, nausea is particularly significant and should be communicated to patients as a point of awareness. Understanding this can help patients manage their expectations and report persistent symptoms to their healthcare providers, potentially leading to adjustments in their contraceptive method if necessary.
