This medication is used to treat vaginal yeast infections. Sulfanilamide reduces vaginal burning, itching, and discharge that may occur with this condition. This medication is known as a sulfonamide antifungal. It works by stopping the growth of yeast (fungus) that causes the infection.
This medication is for vaginal use only. Wash your hands before and after use. Use sulfanilamide usually once or twice daily or as directed by your doctor. Lie on your back with your knees toward your chest. Insert one applicator full of cream into the vagina as far as it will comfortably go. Slowly press the plunger of the applicator all the way in to apply the cream. If you have itching/burning around the outside of the vagina (vulva), apply some cream to that area as well. Consult your doctor or pharmacist if you have any questions on the use of this medication.
Continue to use this medication every day for the full time prescribed, even if symptoms disappear after a few days or if your menstrual period starts. Stopping the medication too soon may allow the yeast infection to return.
Do not use tampons while using this medication. Unscented sanitary napkins may be used for your menstrual period or to protect your clothing from leakage of the medication.
Tell your doctor if your condition persists or returns within 2 months after completing the treatment. Also, tell your doctor immediately if you have fever, chills, flu-like symptoms, or stomach/abdominal pain. This may mean you have a more serious infection and may need another treatment.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: new or increased burning/itching/discomfort in the vaginal area.
Tell your doctor immediately if any of these rare but serious side effects occur: unusual tiredness, dark urine, easy bruising/bleeding.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
