How should I use Gynazole-1?

Gynazole-1 is usually given as a single dose. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Do not take Gynazole-1 by mouth. It is for use only in your vagina.

This medicine comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

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.

Call your doctor if your symptoms do not improve, or if your infection goes away and comes back. Frequent vaginal yeast infections that do not clear up with treatment may be a sign of a more serious condition.

Gynazole-1 contains mineral oil, which can weaken the latex rubber in a condom or diaphragm. These forms of birth control may be less effective if you use them during your treatment with this medicine. Use another form of birth control while you are using butoconazole and for at least 3 full days after your treatment ends.

Store at room temperature away from moisture and heat. Do not warm the medicine applicator before using Gynazole-1.

What happens if I miss a dose?

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

What happens if I overdose?

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

What should I avoid after using Gynazole-1?

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.

Avoid using other vaginal products at the same time as Gynazole-1, unless your doctor tells you to.

Gynazole-1 side effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

  • pelvic pain or cramps;

  • vaginal burning or itching;

  • vaginal pain and swelling; or

  • mild vaginal irritation after use.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect Gynazole-1?

It is not likely that other drugs you take orally or inject will have an effect on butoconazole 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.
