Can femara (letrozole) (used for breast cancer) have gum bleeding as a side effect ?

Yes: Please notify our doctor if you have that side effect.

Indirectly: Any challenge to your immune system or normal hormones can make your gums more susceptible to infection. Good home and professional care should control the bleeding.

Controllable w-floss: So vascularized with blood vessels, gums look pink to red. Hormones and medications can make them "hyper-reactive" to plaque setting off an immune response that includes bleeding. Additionally, meds that cause dry mouth can increase plaque levels by reducing the self cleansing (plaque diluting) action of saliva. Try flossing, accurately and carefully twice a day. Skipping a single day =bleed.
