Summary
Brief summary (as posted)
The purpose of this study is to determine if it is feasible for women to take both Flibanserin and tamoxifen for the duration of the study. This study is also trying to find out if Flibanserin improves or has any effect on hyposexual desire disorder/HSDD in women who are taking tamoxifen for breast cancer.

The criteria states that there must be a decrease in sexual desire and this must be a change for at least 3 months from what it was previously. Personal distress resulting from this change must occur. Initial screening will take place with The Decreased Sexual Desire Screener, a 5-question screening tool developed and validated to aid clinicians in making the diagnosis of HSDD. A "yes" response to the first 4 questions on the screener is consistent with HSDD. * Patients must agree to follow the guidelines for alcohol consumption during the 24 weeks of treatment on study * English speaking * Able to participate in the informed consent process Exclusion Criteria: * Active secondary cancer requiring cytotoxic chemotherapy * History or current diagnosis of metastatic breast cancer. * Unwillingness to follow alcohol guidelines while taking flibanserin * Hepatic dysfunction (more than 2 times the upper limit of normal for alt, ast, t.bili or alk phos) proven by Comprehensive Metabolic Panel (CMP) performed within 6 months of protocol enrollment and while the patient was on Tamoxifen or an AI * Patients on strong CYP3A4 inhibitors including ketoconazole, itraconazole, posaconazole, clarithromycin, nefazodone, ritonavir, saquinavir, nelfinavir, indinavir, boceprevir, telaprevir, telithromycin, conivaptan * Patients on moderate CYP3A4 inhibitors including Amprenavir, atazanavir, ciprofloxacin, diltiazem, erythromycin, fluconazole, fosamprenavir, verapamil, grapefruit juice * Non-English speaking * Unable to participate in the informed consent process
