"In clinical trials, ORTHO TRI-CYCLEN LO had a low discontinuation rate (4%) due to adverse events. The most frequent adverse events resulting in discontinuation were headache, cervical dysplasia, emotional lability, nausea and abdominal pain.
ORTHO TRI-CYCLEN LO has a low incidence of breakthrough bleeding and spotting—an inconvenient and sometimes embarrassing side effect. In a clinical study, fewer than 1 in 5 ORTHO TRI-CYCLEN LO users reported these potentially embarrassing side effects in their first month on the Pill."

"Oral contraceptives are not for everybody. Most side effects of the Pill are not serious and those that are, occur infrequently. Serious risks, which can be life threatening, include blood clots, stroke and heart attacks and are increased if you smoke cigarettes. Cigarette smoking increases the risk of serious cardiovascular side effects, especially if you are over 35. Women who use oral contraceptives are strongly advised not to smoke. Some women should not use the Pill, including women who have blood clots, certain cancers, a history of heart attack or stroke, as well as those who are or may be pregnant. The Pill does not protect against HIV or sexually transmitted diseases."
