I am having surgery in a couple of days and my doctor prescribed me a 10 mg pill of diazepam to calm me the night before surgery. I am also taking 30 mg of fluoxetine and 1.25 mg of risperidone each day for anxiety and OCD. I told my doctor which medications i take. I looked online and it said that there is a moderate drug interaction between risperidone and diazepam. It also said there is a moderate, and sometimes very dangerous, interaction between diazepam and fluoxetine. Is it safe to take these medications together just this one time?
