WHAT ARE ANTIDEPRESSANTS?
There are several types of antidepressants. The ones that are prescribed the most are SSRI (Lexapro, Prozac, Paxil, Pexeva, Zoloft) and SSNRI (Cymbalta, Effexor) drugs.
WHAT ARE SSRI and SSNRI?
SSRI drugs influence the brain chemical serotonin. This neurotransmitter signals calming and soothing effects. SSNRIs also have an effect on the neurotransmitter norepinephrine. Exhaustion and lack of focus are usual symptoms when nerves are deficient in norepinephrine.
HOW DO THE DRUGS WORK?
SSRI and SSNRI drugs are synthetic chemicals. If your nerves are deficient in serotonin and/or norepinephrine , the drugs will not increase your body's own production of the brain chemicals. Rather, they slow down the normal rate by which they transmit messages and are recycled. This is why they are called "reuptake inhibitors". Slower nerve transmission means slower brain and body functions.
WHY ARE THERE SIDE EFFECTS WHEN I STOP TAKING AN ANTIDEPRESSANT?
These drugs slow down nerve impulses, which allows serotonin (or norepinephrine) to remain longer in nerves. When you stop taking the drug, nerves resume their normal rate of transmission and the deficiencies of serotonin or norepinephrine become apparent. You may again feel some of the symptoms—sometimes more intensely—that made you start taking the antidepressant in the first place.
WHY ARE THERE MORE SIDE EFFECTS DURING WITHDRAWAL FROM CERTAIN ANTIDEPRESSANTS?
Withdrawal symptoms are usually more severe when you withdraw from an antidepressant that is short acting (stays in the body for a shorter period of time). These include Effexor, Cymbalta , Celexa, Lexapro, Paxil and Zoloft.
