Trying to find out the probability of drug interaction for Prozac and Strattera - he is passing out and voices etc fluctuate - are worse and not as bad throughout the day, 4 - 8 PM being the worst for depression etc. He has psychosis and PTSD induced anxiety, ADD. Wondering if Strattera might be the issue because of the listed side effects. I also know Prozac effects the blood level of Strattera. This has been worse since the recent hosp when they went up and down on the Prozac (we had to go back to 60 mg as it was before) and tried Wellbutrin which was stopped because he couldn't control anger.
