Healthy
women who do not smoke cigarettes have almost no chance of
having a severe side effect from taking oral contraceptives.
For most women, more problems occur because of pregnancy
than will occur from taking oral contraceptives. But for
some women who have special health problems, oral
contraceptives can cause some unwanted effects. Some of
these unwanted effects include benign (not cancerous) liver
tumors, liver cancer, or blood clots or related problems,
such as a stroke. Although these effects are very rare, they
can be serious enough to cause death. You may want to
discuss these effects with your doctor.
Smoking
cigarettes during the use of oral contraceptives has been
found to greatly increase the chances of these serious side
effects occurring. To reduce the risk of serious side
effects, do not smoke cigarettes while you are taking oral
contraceptives.
The
following side effects may be caused by blood clots. Get
emergency help immediately if any of the following side
effects occur:
Abdominal or stomach pain (sudden, severe, or continuing);
anxiety; burning pain in lower abdomen ; changes in skin
color; chill; coughing up blood; convulsions; fever;
feeling of heat; feeling of warmth in lips and tongue;
headache (severe or sudden); loss of coordination
(sudden); loss of vision or change in vision (sudden);
nervousness; numbness of the fingertips; pain in lower

(especially in calf of leg); ringing in the ears; shortness
of breath (sudden or unexplained); slurring of speech
