What should I watch for?
Tell your doctor or health care professional if your symptoms do not start to get better within a few days.
If you develop abdominal pain, a fever greater than 100 degrees F, or foul-smelling vaginal discharge, contact your doctor or health care professional. Do not self-treat if you have these symptoms. These are signs of a more serious infection and you will need examined by a qualified health care professional.
It is better not to have unprotected sex until you have completely finished this treatment. Many vaginal infections are spread by sexual activity. It is recommended that your partner wear a condom during intercourse while you are being treated. If your partner has itching or redness of the genitals, they should also see a health care professional about these symptoms. They may also need evaluation and treatment.
Your clothing may get soiled if you have a vaginal discharge. You can wear a sanitary napkin. Do not use tampons. Tampons can absorb this medicine and decrease the efficacy of the medication. If possible, wear freshly washed cotton, not synthetic, panties.
