Possible side effects of ethinylestradiol/megestrol acetate include nausea, vomiting, headache, bloating, breast tenderness, and changes in menstrual cycle.

Interactions[edit]

Ethinylestradiol/megestrol acetate may interact with other medications, including certain antibiotics, antifungal medications, and HIV medications. It is important to inform your healthcare provider of all medications you are taking before starting ethinylestradiol/megestrol acetate.
