Does being on Prozac (fluoxetine) affect which drugs you can use for gen anesth?

Not significantly. Fluoxetine blocks an enzyme at the liver that breaks down some medications. Most anesthetic medications are either not metabolized at all-- the inhaled agents-- or are broken down by several mechanisms. Fluoxetine does not affect hemodynamics or other life functions in a way that would interfere with anesthesia.
No. Prozac (fluoxetine) does increases levels of serotonin, a neurotransmitter; narcotics do also. If too many drugs are given which increase serotonin, a serious complication- serotonin syndrome, can occur. But this would be very unusual at normal doses. Your anesthesia provider should however always know about all the drugs you are taking, including over the counter and herbal supplements.
Not really. Prozac (fluoxetine) causes reputable of a brain chemical called serotonin. Make sure your anesthesiologist knows you take it. Use of Prozac (fluoxetine) has no effect in what we use for ga.
No. No worries here, the ssri medications are safe to take up until the day of and can be immediately continued.
