US warns about yeast treatment, drug interaction

WASHINGTON, Mar 06 (Reuters) - US regulators on Monday warned women taking a

prescription anti-clotting drug that using certain over-the-counter yeast

infection treatments at the same time could cause bruising and bleeding.

The Food and Drug Administration (FDA) urged women being treated with the

anti-clotting drug, warfarin, to consult with their doctors before using

& 's Monistat or other vaginal yeast-fighting medications

that contain miconazole.

The FDA said it had asked makers of creams and suppositories containing

miconazole to include a warning on the products' packaging about the

possible interaction.

Regulators took action after receiving two reports of abnormal

blood-clotting tests in women taking warfarin and a miconazole product, the

FDA said in a statement. One woman developed bruises, bleeding gums and a

nosebleed, the agency said.

" Physicians and patients should be aware that patients who need to use both

products simultaneously should be appropriately monitored, " the FDA said.
