Treatment for an eating disorder commonly includes a multi-disciplinary approach with the psychotherapist and psychiatrist as the primary treatment providers. In addition, a licensed dietician and a primary care physician make up the rest of the team involved in the care of the patient. Depending on the type of eating disorder diagnosed, use of specific pharmacotherapy can also be effective.
To date, there has not been much success in treating anorexia nervosa with psychotropic drugs to cure the physical aspects of the disease. Indeed, food is still the best medicine for regaining physical wellbeing for anorectics. However, some SSRIs have shown promise in treating the underlying mental health conditions that accompany the eating disorder, once a healthy weight has been attained.
There has been much more success treating patients with psych meds who present with bulimia nervosa or a binge eating disorder. It has been found that bulimics respond well to antidepressants, even if they are not suffering from depression.
Drug Treatment for Anorexia Nervosa
The most challenging eating disorder to treat is anorexia. Psychotherapy remains the primary tool used to stabilize and treat this eating disorder, as there are typically serious mental health issues that accompany the disordered eating. To date, there has been little evidence that medication is effective in treating anorexia, but when mood disorders such as depression or obsessive-compulsive disorder accompany the disorder, Fluoxetine (Prozac) has helped the anorectic patient manage these.
Side effects of these selective serotonin uptake inhibitors (SSRIs) are generally mild and tolerated well for most patients. Side effects can include:
- Decreased interest in sex
- Weight gain
If the patient does not tolerate the SSRI, then their psychiatrist may prescribe olanzapine (Zyprexa), a psychotropic drug used primarily to treat schizophrenia. In a patient who has anorexia nervosa, olanzapine can help them gain weight and modify their obsessive thinking. Side effects of olanzapine include:
- Dyskinesia (movement disorder)
In addition, anti-anxiety medications can be effective in reducing the anxiety the patient may experience before eating.
Drug Treatment for Bulimia Nervosa
Patients diagnosed with bulimia nervosa tend to respond well to fluoxetine in reducing the binge eating and purging. This is the only antidepressant that is approved by the U.S. Food and Drug Administration to treat bulimia nervosa.
In addition to fluoxetine, another group of antidepressant drugs called tricyclics (Norpramin, Tofranil, and Elavil) have been prescribed with some success. They have similar side effects as the antidepressants, but also have more risk of overdose and drug interactions.
Several placebo-controlled trials have shown topiramate (Topamax) to be effective in controlling binge and purge behaviors. Side effects include taste perversion, difficulty concentrating, and a sensation of pins and needles or skin crawling.
Studies with lithium demonstrated it is ineffective in treating bulimia.
Drug Treatment for Binge Eating Disorder
In treating binge eating disorders, the most effective drug has been topiramate , a medication usually associated with treating epileptic seizures and migraine headaches, as well as bipolar disorder. Side effects are listed above.
SSRIs (Prozac and Zoloft) and appetite suppressants (such as Meridia) have also been effective in treating the binge-eating behaviors. Appetite suppressants can help suppress hunger, which helps in weight loss, but they can have serious side effects. Common side effects of Meridia include dangerous changes in blood pressure, headache, dry mouth, and sleep disturbance.
