Call your doctor if your symptoms do not improve after 3 days, or if you still have symptoms for longer than 7 days. Frequent vaginal yeast infections that do not clear up with treatment may be a sign of a more serious condition.

The single-use applicator is for one use only. Throw the applicator away after one use, even if there is still some medicine left in it after inserting your dose.

What happens if I miss a dose?

Since 1-Day is used as a single dose, it does not have a daily dosing schedule.

What happens if I overdose?

Since 1-Day is used as a single dose from a prefilled applicator, an overdose is unlikely to occur.

What should I avoid while using 1-Day?

Avoid wearing tight-fitting, synthetic clothing such as nylon underwear or panty hose that does not allow air circulation. Wear loose-fitting clothing made of cotton and other natural fibers until your infection is healed.

Do not use a tampon, vaginal douche, spermicide, or other vaginal products while you are using 1-Day. Do not have vaginal intercourse during treatment.

What other drugs will affect 1-Day?

It is not likely that other drugs you take orally or inject will have an effect on tioconazole used in the vagina. But many drugs can interact with each other. Tell each of your healthcare providers about all medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products.
