@kmcin28 Fluoxetine is an antidepressant which has been around for a number of years which helps with depression around week 4 to 6 and also with anxiety around week 6 to 8.
The diazepam aka valium works by reducing symptons of anxiety. Its a fabulous medication for short term use but not great for long term use as people do build a tolerance and start to require more of it.
Both medications should be taken under close Dr contact and especially if stopping as both are better being reduced slowly.
Diazepam if taken very regularly every day (and I mean throughout the day also) does result in dependence if that continues for a number of weeks. The sympyoms of that is rebound anxiety symptoms, sweating and shakes. But if you do follow your Drs guidelines and start / stop with their input you shouldn't have issues.
I think you should rebook an appointment with your Dr about the class of antidepressant he/she has chosen. Fluoxetine is classed as a SSRI medication and is not now recommended as the best choice for women who have had breast cancer on tamoxifen in particular. I'm unsure if its the same for an AI. You might be best seeking confirmation with your oncologist about this or breast care nurse. I'm sure you could just ask this question with a phone call and they check it out for you. Kath x.
