Does Prozac make Xanax stronger

Prozac is an SSRI, a specific serotonin reuptake inhibitor. Xanax is a sedative. Prozac works by slowing the breakdown of serotonin, therefore increasing the quantity in the synapse and your brain. Xanax works by slowing down the nerve impulses (I think).

One doesn't make the other stronger, but prozac might get metabolized first by the liver, causing an increase in blood xanax levels.

Talk to your pharmacist.
