>>8183"The effect of serotonin in elevating body steroids also gives reason for the “amphetamine effect” felt with the use of Prozac. Cortisol is an adrenalin hormone and adrenalins (epinephrines) are like the body’s own version of amphetamines. Adrenaline or epinephrine and amphetamine are chemically related so an increase in adrenalin is similar to a dose of amphetamine.
Prozac and the other SSRIs produce this effect by artificially increasing the level of serotonin which stimulates the adrenal glands to produce more adrenalin – the body’s glandular amphetamine.
Prozac or any SSRI should also logically produce the same mental and physical side effects associated with the use of steroids. The only difference is that the SSRI drugs accomplish this by artificially forcing or chemically increasing the body’s own steroid production. We should, therefore, expect the SSRI drugs to cause the same serious physical and psychiatric reactions caused by steroids and amphetamines.”"
