What Drugs Interact With Gyne-Lotrimin?

Gyne-Lotrimin may interact with other vaginal creams or douches used at the same time. Tell your doctor all medications and supplements you use.

If you are pregnant, follow your doctor's instructions on how to use the applicator to insert this medication. It is unknown whether this drug passes into breast milk. Consult your doctor before breastfeeding.

How Should Flagyl Be Taken?

Flagyl is supplied in 250 and 500 mg strength tablets, Flagyl ER is available in 750 mg strength tablets, and Flagyl Injection in 500 mg strength in a buffered 100 ml vial. Dosage is quite variable and dependent upon the severity of disease and other considerations made by the treating physician. Most of the serious side effects may occur with any of these three preparations of Flagyl. Flagyl may cause liver enzyme levels to increase; lithium and creatinine levels should be checked to avoid lithium toxicity or renal compromise. Alcohol may increase the side effects of Flagyl. Patients on disulfiram should not take Flagyl until they have had a two week interval without taking disulfiram, especially alcoholic patients, to avoid psychotic reactions. Treatment in pregnant women (during first 3 months is not advised) or women who are breastfeeding should only be done if the benefits outweigh the potential problems. Flagyl passes into breast milk and may harm a nursing baby. Consult your doctor before breastfeeding. Except for use in amebiasis, studies in pediatric patients are not available; Flagyl ER has no pediatric studies.

How Should Gyne-Lotrimin Be Taken?

Fill the applicator with the cream and then insert one applicatorful dose of Gyne-Lotrimin cream into the vagina every day, preferably at bedtime. Dispose of applicator after use. Repeat this procedure with a new applicator for 7 consecutive days. In order to kill the yeast completely, you must use Gyne-Lotrimin the full seven days, even if symptoms are relieved sooner.
