I'm on prozac (fluoxetine) 20mg and epilim for mood 500mg in the mornings and I'm taking mianserin 10mg, risperidone 1mg at night can I take tripiline 25mg as well?

Risk on top of risk. Too many medications, IMHO. Discuss all of these in combination w/ your doctor or pharmacist and ask for printed info so you can read it yourself. Consider adding CBT therapy - risk free and effective!
