The chemical that was to become Prozac was largely developed in the 1970s. However, it wasn't until 1987 that it was launched as Prozac - the new miracle cure for depression.
The psychiatric landscape of 1987 was one dominated by highly addictive tranquillisers and highly toxic TCA antidepressants. Prozac appeared to offer a more effective treatment for depression without the toxicity and addictive properties. Concern about side effects and withdrawal symptoms were some way into the future.
