Final answer:
The medication most commonly used to treat Anorexia Nervosa and Bulimia Nervosa is fluoxetine (Prozac), a Selective Serotonin Reuptake Inhibitor (SSRI).
Step-by-step explanation:
The medication most commonly used to treat Anorexia Nervosa and Bulimia Nervosa is fluoxetine, which is a Selective Serotonin Reuptake Inhibitor (SSRI). Fluoxetine, known by the brand name Prozac, is effective in increasing serotonin levels in the central nervous system, which can help manage symptoms associated with these eating disorders. In the treatment of both anorexia and bulimia, the goal of medication is to support recovery, which includes gaining control of eating behaviour and adopting normal eating habits. Fluoxetine has been found to help reduce binge-eating episodes and purge behaviours in individuals with bulimia nervosa. Although fluoxetine is the only FDA-approved drug for the treatment of eating disorders, other SSRIs may also be used off-label.
The management of eating disorders typically involves a combination of psychological therapy and medication. It is crucial that treatment is tailored to the individual's needs and often includes addressing psychological, behavioural, nutritional, and other health concerns.
