Drinking alcoholic beverages while using this medicine may cause stomach pain, nausea, vomiting, headache, or flushing or redness of the face.

Vaginal medicines usually leak out of the vagina during treatment. To keep the medicine from getting on your clothing, wear a mini-pad or sanitary napkin. Do not use tampons (like those used for menstrual periods) since they may soak up the medicine.
To help clear up your infection completely and to help make sure it does not return, good health habits are also required.
- Wear cotton panties (or panties or pantyhose with cotton crotches) instead of synthetic (e.g., nylon or rayon) panties.
- Wear only freshly washed panties daily.
Do not have sexual intercourse while you are using this medicine. Having sexual intercourse may reduce the strength of the medicine. This may keep the medicine from working properly. Also, oils in the cream and vaginal tablets (but not the vaginal gel) may damage latex (rubber) contraceptive devices (e.g., cervical caps, condoms, or diaphragms), causing them to leak, wear out sooner, or not work properly.
Avoid using douches or other vaginal products unless your doctor tells you to.
Many vaginal infections (e.g., trichomoniasis) are spread by having sexual intercourse. You can give the infection to your sexual partner, and the infection could be given back to you. Your partner may also need to be treated for some infections. Until you are sure that the infection is completely cleared up after your treatment with this medicine, your partner should wear a condom during sexual intercourse . If you have any questions about this, check with your doctor.
Before you have any medical tests, tell the medical doctor in charge that you are using this medicine. The results of some tests may be affected by this medicine.
