I am a Graduate student. At times, I feel quite depressed. Is it Ok to use antidepressants drugs?
Tricyclic antidepressants (TCA) work by raising the levels of serotonin and norepinephrine in the brain by slowing the rate of reuptake, or re-absorption, by nerve cells. Usually TCAs are taken over an extended period as results from the drugs are gradual. Because of the possibility of causing serious cardiac complications, TCAs can be lethal if misused at high doses. Abuse of TCAs can be the result of fear of relapse rather than any psycho-pharmacological effect however the potential for TCA abuse is well established, since the drugs have clearly defined euphoric psychological and stimulatory physiological action in cases of chronic usage.
