Name a common side effect of using combination oral contraceptives.

• A. Nausea
• B. Breast tenderness
• C. Weight loss
• D. Hair growth

Answer: (B)

Combination oral contraceptives, which contain both estrogen and progestin, are commonly used for various purposes including contraception, regulation of menstrual cycles, and management of conditions like polycystic ovary syndrome. One of the well-documented side effects of these medications is breast tenderness. The hormonal changes induced by the contraceptives can lead to increased sensitivity and fullness in breast tissue, often manifesting as discomfort or pain.

While nausea can also occasionally be experienced when starting hormonal contraceptives, it is less specific to their use compared to breast tenderness. Weight loss is not a typical side effect associated with combination oral contraceptives, as many women may experience weight gain. Hair growth is not generally a side effect of combination pills; instead, it might be associated with conditions like polycystic ovarian syndrome or other hormonal imbalances. Therefore, breast tenderness is a notable and common side effect associated with the use of combination oral contraceptives, making it the correct choice.
