Symptoms: Overdosage of estrogen-plus-progestin therapy may cause nausea and vomiting, breast tenderness, abdominal pain, drowsiness/fatigue, and withdrawal bleeding may occur in women.
Even girls who have not yet started to menstruate but have accidentally taken this medicine may experience such bleeding.
If the patient has taken too many HERZ tablets, or discovers that a child has taken some, ask the doctor or pharmacist for advice.
