Diflucan or Fluconazole decrease NuvaRing's affectivness

Hi,
Welcome to ehealthforum,
Use of other medications along with use of hormonal contraceptives can affect their effectiveness and put you at risk for pregnancy (the risk is higher with oral contraceptive pill use as their absorption is affected by use of other medications). Other forms of hormonal contraceptives that get affected are Nuvaring, and Ortho-Evra patch. You should consider using back-up protection (condom/spermicide) for additional protection if having intercourse while using any other medications like antibiotics, or anti-fungals, or anti-seizure drugs, anti-HIV drugs, antidepressants, diabetes medication, anxiety treatment medications, natural supplements, diet pills, etc (if you are worried about pregnancy). Visit your doctor/gynecologist for further clarification and assistance.
Take care.
