Drugs Used to Treat Mental Disorders

What Drugs Are Used to Treat Depression?

When treating depression, several drugs are available. Some of the most commonly used include:

Antisocial Personality Disorder

People with antisocial personality disorder (ASPD) can be witty, charming, and fun to be around -- but they also lie and exploit others. ASPD makes people uncaring. Someone with the disorder may act rashly, destructively, and unsafely without feeling guilty when their actions hurt other people. Experts don’t agree on whether antisocial personality disorder and psychopathy (i.e. "a psychopath") are the same thing. Either way, ASPD is uncommon, affecting just .6% of the population.

In some cases, a combination of antidepressants may be necessary. Sometimes an antidepressant combined with a second antidepressant from a different class, or a different type of medication altogether, such as a mood stabilizer (like lithium) or atypical antipsychotic (like Seroquel or Abilify) can boost the effect of an antidepressant alone.

Side effects vary, depending on what type of medication you are taking, and may improve once your body adjusts to the medication.

If you decide to stop taking your antidepressants, it is important that you gradually reduce the dose over a period of time recommended by your doctor. Quitting antidepressants abruptly can cause discontinuation symptoms such as headache or dizziness or increase the chance that symptoms will return. It is important to discuss tapering off (or changing) medications with your health care provider first.

What Medications Are Used to Treat Anxiety Disorders?

When treating anxiety disorders, antidepressants, particularly the SSRIs, have been shown to be effective.

Other anti-anxiety drugs include the benzodiazepines, such as Valium, Ativan and Xanax. These drugs do carry a risk of addiction or tolerance (meaning that higher and higher doses become necessary to achieve the same effect), so they are not as desirable for long-term use. Other possible side effects include drowsiness, poor concentration, and irritability. Some anticonvulsant drugs (such as Lyrica or Neurontin) and some atypical antipsychotics (such as Abilify or Seroquel) are also occasionally used "off label" to treat anxiety symptoms or disorders.
