Psychiatric Medications - Psychiatric Medications for Adults and Children

Written by NIMH

The newer antidepressants, including SSRIs, have different types of side effects, as follows:

• Sexual problems—fairly common, but reversible, in both men and women. The doctor should be consulted if the problem is persistent or worrisome.
• Headache—this will usually go away after a short time.
• Nausea—may occur after a dose, but it will disappear quickly.
• Nervousness and insomnia (trouble falling asleep or waking often during the night)—these may occur during the first few weeks; dosage reductions or time will usually resolve them.
• Agitation (feeling jittery)—if this happens for the first time after the drug is taken and is more than temporary, the doctor should be notified.
• Any of these side effects may be amplified when an SSRI is combined with other medications that affect serotonin. In the most extreme cases, such a combination of medications (e.g., an SSRI and an MAOI) may result in a potentially serious or even fatal "serotonin syndrome," characterized by fever, confusion, muscle rigidity, and cardiac, liver, or kidney problems.

The small number of people for whom MAOIs are the best treatment need to avoid taking decongestants and consuming certain foods that contain high levels of tyramine, such as many cheeses, wines, and pickles. The interaction of tyramine with MAOIs can bring on a sharp increase in blood pressure that can lead to a stroke. The doctor should furnish a complete list of prohibited foods that the individual should carry at all times. Other forms of antidepressants require no food restrictions. MAOIs also should not be combined with other antidepressants, especially SSRIs, due to the risk of serotonin syndrome.

Medications of any kind—prescribed, over-the-counter, or herbal supplements—should never be mixed without consulting the doctor; nor should medications ever be borrowed from another person. Other health professionals who may prescribe a drug—such as a dentist or other medical specialist—should be told that the person is taking a specific antidepressant and the dosage. Some drugs, although safe when taken alone, can cause severe and dangerous side effects if taken with other drugs. Alcohol (wine, beer, and hard liquor) or street drugs, may reduce the effectiveness of antidepressants and their use should be minimized or, preferably, avoided by anyone taking antidepressants. Some people who have not had a problem with alcohol use may be permitted by their doctor to use a modest amount of alcohol while taking one of the newer antidepressants. The potency of alcohol may be increased by medications since both are metabolized by the liver; one drink may feel like two.

Although not common, some people have experienced withdrawal symptoms when stopping an antidepressant too abruptly. Therefore, when discontinuing an antidepressant, gradual withdrawal is generally advisable.

Questions about any antidepressant prescribed, or problems that may be related to the medication, should be discussed with the doctor and/or the pharmacist.

ANTIANXIETY MEDICATIONS

Everyone experiences anxiety at one time or another—"butterflies in the stomach" before giving a speech or sweaty palms during a job interview are common symptoms. Other symptoms include irritability, uneasiness, jumpiness, feelings of apprehension, rapid or irregular heartbeat, stomachache, nausea, faintness, and breathing problems.

Anxiety is often manageable and mild, but sometimes it can present serious problems. A high level or prolonged state of anxiety can make the activities of daily life difficult or impossible. People may have generalized anxiety disorder (GAD) or more specific anxiety disorders such as panic, phobias, obsessive-compulsive disorder (OCD), or post-traumatic stress disorder (PTSD).

Both antidepressants and antianxiety medications are used to treat anxiety disorders. The broad-spectrum activity of most antidepressants provides effectiveness in anxiety disorders as well as depression. The first medication specifically approved for use in the treatment of OCD was the tricyclic antidepressant clomipramine (Anafranil). The SSRIs, fluoxetine (Prozac), fluvoxamine (Luvox), paroxetine (Paxil), and sertraline (Zoloft) have now been approved for use with OCD. Paroxetine has also been approved for social anxiety disorder (social phobia), GAD, and panic disorder; and sertraline is approved for panic disorder and PTSD. Venlafaxine (Effexor) has been approved for GAD.

Antianxiety medications include the benzodiazepines, which can relieve symptoms within a short time. They have relatively few side effects: drowsiness and loss of coordination are most common; fatigue and mental slowing or confusion can also occur. These effects make it dangerous for people taking benzodiazepines to drive or operate some machinery. Other side effects are rare.

Benzodiazepines vary in duration of action in different people; they may be taken two or three times a day, sometimes only once a day, or just on an "as-needed" basis. Dosage is generally started at a low level and gradually raised until symptoms are diminished or removed. The dosage will vary a great deal depending on the symptoms and the individual's body chemistry.
