Psychiatric Medications: Medications for Mental Illness - Purpose of Psychiatric Medications and Questions for Your Doctor

Written by National Institute of Mental Health

Relief from Symptoms

Just as aspirin can reduce a fever without curing the infection that causes it, psychotherapeutic medications act by controlling symptoms. Psychotherapeutic medications do not cure mental illness, but in many cases, they can help a person function despite some continuing mental pain and difficulty coping with problems. For example, drugs like chlorpromazine can turn off the "voices" heard by some people with psychosis and help them to see reality more clearly. And antidepressants can lift the dark, heavy moods of depression. The degree of response—ranging from a little relief of symptoms to complete relief—depends on a variety of factors related to the individual and the disorder being treated.

How long someone must take a psychotherapeutic medication depends on the individual and the disorder. Many depressed and anxious people may need medication for a single period—perhaps for several months—and then never need it again. People with conditions such as schizophrenia or bipolar disorder (also known as manic-depressive illness), or those whose depression or anxiety is chronic or recurrent, may have to take medication indefinitely.

Like any medication, psychotherapeutic medications do not produce the same effect in everyone. Some people may respond better to one medication than another. Some may need larger dosages than others do. Some have side effects, and others do not. Age, sex, body size, body chemistry, physical illnesses and their treatments, diet, and habits such as smoking are some of the factors that can influence a medication's effect.

Questions for Your Doctor

You and your family can help your doctor find the right medications for you. The doctor needs to know your medical history, other medications being taken, and life plans such as hoping to have a baby. After taking the medication for a short time, you should tell the doctor about favorable results as well as side effects. The Food and Drug Administration (FDA) and professional organizations recommend that the patient or a family member ask the following questions when a medication is prescribed:

• What is the name of the medication, and what is it supposed to do?
• How and when do I take it, and when do I stop taking it?
• What foods, drinks, or other medications should I avoid while taking the prescribed medication?
• Should it be taken with food or on an empty stomach?
• Is it safe to drink alcohol while on this medication?
• What are the side effects, and what should I do if they occur?
• Is a Patient Package Insert for the medication available?

Medications for Mental Illness

This booklet describes medications by their generic (chemical) names and in italics by their trade names (brand names used by pharmaceutical companies). They are divided into four large categories—antipsychotic, antimanic, antidepressant, and antianxiety medications. Medications that specifically affect children, the elderly, and women during the reproductive years are discussed in a separate section of the booklet.

Lists at the end of the booklet give the generic name and the trade name of the most commonly prescribed medications and note the section of the booklet that contains information about each type. A separate chart shows the trade and generic names of medications commonly prescribed for children and adolescents.

Treatment evaluation studies have established the effectiveness of the medications described here, but much remains to be learned about them. The National Institute of Mental Health, other Federal agencies, and private research groups are sponsoring studies of these medications. Scientists are hoping to improve their understanding of how and why these medications work, how to control or eliminate unwanted side effects, and how to make the medications more effective.
