Treatment with Medication
The decision to treat mental illness with medication is serious and should be made in consultation with doctors, therapists, family, and, especially, the consumer him/herself. Medications can drastically reduce the symptoms of mental illness, but the side effects, cost, inconvenience, and stigma can be significant and important issues to be addressed when and if medication is prescribed.
Thank you to the NIMH for some of the information below.
Antipsychotic medications act against the symptoms of psychosis, such as those seen in schizophrenia. These medications cannot "cure" the illness, but they can take away many of the symptoms or make them milder. In some cases, they can shorten the course of an episode of the illness as well.
There are a number of antipsychotic (neuroleptic) medications available. These medications affect neurotransmitters that allow communication between nerve cells. One such neurotransmitter, dopamine, is thought to be relevant to schizophrenia symptoms. All these medications have been shown to be effective for schizophrenia. The main differences are in the potency--that is, the dosage (amount) prescribed to produce therapeutic effects-and the side effects. Some people might think that the higher the dose of medication prescribed, the more serious the illness; but this is not always true.
Dosages and side effects
Some drugs are very potent and the doctor may prescribe a low dose. Other drugs are not as potent and a higher dose may be prescribed.
Unlike some prescription drugs, which must be taken several times during the day, some antipsychotic medications can be taken just once a day. In order to reduce daytime side effects such as sleepiness, some medications can be taken at bedtime. Some antipsychotic medications are available in "depot" forms that can be injected once or twice a month.
Most side effects of antipsychotic medications are mild. Many common ones lessen or disappear after the first few weeks of treatment. These include drowsiness, rapid heartbeat, and dizziness when changing position.
Some people gain weight while taking medications and need to pay extra attention to diet and exercise to control their weight. Other side effects may include a decrease in sexual ability or interest, problems with menstrual periods, sunburn, or skin rashes. If a side effect occurs, the doctor should be told. He or she may prescribe a different medication, change the dosage or schedule, or prescribe an additional medication to control the side effects.
Just as people vary in their responses to antipsychotic medications, they also vary in how quickly they improve. Some symptoms may diminish in days; others take weeks or months. Many people see substantial improvement by the sixth week of treatment. If there is no improvement, the doctor may try a different type of medication. The doctor cannot tell beforehand which medication will work for a person. Sometimes a person must try several medications before finding one that works.
If a person is feeling better or even completely well, the medication should not be stopped without talking to the doctor. It may be necessary to stay on the medication to continue feeling well. If, after consultation with the doctor, the decision is made to discontinue the medication, it is important to continue to see the doctor while tapering off medication. Many people with bipolar disorder, for instance, require antipsychotic medication only for a limited time during a manic episode until mood-stabilizing medication takes effect. On the other hand, some people may need to take antipsychotic medication for an extended period of time. These people usually have chronic (long-term, continuous) schizophrenic disorders, or have a history of repeated schizophrenic episodes, and are likely to become ill again. Also, in some cases a person who has experienced one or two severe episodes may need medication indefinitely. In these cases, medication may be continued in as low a dosage as possible to maintain control of symptoms. This approach, called maintenance treatment, prevents relapse in many people and removes or reduces symptoms for others.
Multiple medications
Antipsychotic medications can produce unwanted effects when taken with other medications. Therefore, the doctor should be told about all medicines being taken, including over-the-counter medications and vitamin, mineral, and herbal supplements, and the extent of alcohol use. Some antipsychotic medications interfere with antihypertensive medications (taken for high blood pressure), anticonvulsants (taken for epilepsy), and medications used for Parkinson's disease. Other antipsychotics add to the effect of alcohol and other central nervous system depressants such as antihistamines, antidepressants, barbiturates, some sleeping and pain medications, and narcotics.
Other effects.
Long-term treatment of schizophrenia with one of the older, or "conventional," antipsychotics may cause a person to develop tardive dyskinesia (TD). Tardive dyskinesia is a condition characterized by involuntary movements, most often around the mouth. It may range from mild to severe. In some people, it cannot be reversed, while others recover partially or completely. Tardive dyskinesia is sometimes seen in people with schizophrenia who have never been treated with an antipsychotic medication; this is called "spontaneous dyskinesia." However, it is most often seen after long-term treatment with older antipsychotic medications. The risk has been reduced with the newer "atypical" medications. There is a higher incidence in women, and the risk rises with age. The possible risks of long-term treatment with an antipsychotic medication must be weighed against the benefits in each case. The risk for TD is 5 percent per year with older medications; it is less with the newer medications.
Bipolar disorder is characterized by cycling mood changes: severe highs (mania) and lows (depression). Episodes may be predominantly manic or depressive, with normal mood between episodes. Mood swings may follow each other very closely, within days (rapid cycling), or may be separated by months to years. The "highs" and "lows" may vary in intensity and severity and can co-exist in "mixed" episodes.
When people are in a manic "high," they may be overactive, overly talkative, have a great deal of energy, and have much less need for sleep than normal. They may switch quickly from one topic to another, as if they cannot get their thoughts out fast enough. Their attention span is often short, and they can be easily distracted. Sometimes people who are "high" are irritable or angry and have false or inflated ideas about their position or importance in the world. They may be very elated, and full of grand schemes that might range from business deals to romantic sprees. Often, they show poor judgment in these ventures. Mania, untreated, may worsen to a psychotic state.
In a depressive cycle the person may have a "low" mood with difficulty concentrating; lack of energy, with slowed thinking and movements; changes in eating and sleeping patterns (usually increases of both in bipolar depression); feelings of hopelessness, helplessness, sadness, worthlessness, guilt; and, sometimes, thoughts of suicide.
Lithium
The medication used most often to treat bipolar disorder is lithium. Lithium evens out mood swings in both directions--from mania to depression, and depression to mania--so it is used not just for manic attacks or flare-ups of the illness but also as an ongoing maintenance treatment for bipolar disorder.
Although lithium will reduce severe manic symptoms in about 5 to 14 days, it may be weeks to several months before the condition is fully controlled. Antipsychotic medications are sometimes used in the first several days of treatment to control manic symptoms until the lithium begins to take effect. Antidepressants may also be added to lithium during the depressive phase of bipolar disorder. If given in the absence of lithium or another mood stabilizer, antidepressants may provoke a switch into mania in people with bipolar disorder.
A person may have one episode of bipolar disorder and never have another, or be free of illness for several years. But for those who have more than one manic episode, doctors usually give serious consideration to maintenance (continuing) treatment with lithium.
Some people respond well to maintenance treatment and have no further episodes. Others may have moderate mood swings that lessen as treatment continues, or have less frequent or less severe episodes. Unfortunately, some people with bipolar disorder may not be helped at all by lithium. Response to treatment with lithium varies, and it cannot be determined beforehand who will or will not respond to treatment.
Regular blood tests are an important part of treatment with lithium. If too little is taken, lithium will not be effective. If too much is taken, a variety of side effects may occur. The range between an effective dose and a toxic one is small. Blood lithium levels are checked at the beginning of treatment to determine the best lithium dosage. Once a person is stable and on a maintenance dosage, the lithium level should be checked every few months. How much lithium people need to take may vary over time, depending on how ill they are, their body chemistry, and their physical condition.
Side effects of lithium.
When people first take lithium, they may experience side effects such as drowsiness, weakness, nausea, fatigue, hand tremor, or increased thirst and urination. Some may disappear or decrease quickly, although hand tremor may persist. Weight gain may also occur. Dieting will help, but crash diets should be avoided because they may raise or lower the lithium level. Drinking low-calorie or no-calorie beverages, especially water, will help keep weight down. Kidney changes--increased urination and, in children, enuresis (bed wetting)--may develop during treatment. These changes are generally manageable and are reduced by lowering the dosage. Because lithium may cause the thyroid gland to become underactive (hypothyroidism) or sometimes enlarged (goiter), thyroid function monitoring is a part of the therapy. To restore normal thyroid function, thyroid hormone may be given along with lithium.
Because of possible complications, doctors either may not recommend lithium or may prescribe it with caution when a person has thyroid, kidney, or heart disorders, epilepsy, or brain damage. Women of childbearing age should be aware that lithium increases the risk of congenital malformations in babies. Special caution should be taken during the first 3 months of pregnancy.
Anything that lowers the level of sodium in the body--reduced intake of table salt, a switch to a low-salt diet, heavy sweating from an unusual amount of exercise or a very hot climate, fever, vomiting, or diarrhea--may cause a lithium buildup and lead to toxicity. It is important to be aware of conditions that lower sodium or cause dehydration and to tell the doctor if any of these conditions are present so the dose can be changed.
Lithium, when combined with certain other medications, can have unwanted effects. Some diuretics--substances that remove water from the body--increase the level of lithium and can cause toxicity. Other diuretics, like coffee and tea, can lower the level of lithium. Signs of lithium toxicity may include nausea, vomiting, drowsiness, mental dullness, slurred speech, blurred vision, confusion, dizziness, muscle twitching, irregular heartbeat, and, ultimately, seizures. A lithium overdose can be life-threatening. People who are taking lithium should tell every doctor who is treating them, including dentists, about all medications they are taking.
With regular monitoring, lithium is a safe and effective drug that enables many people, who otherwise would suffer from incapacitating mood swings, to lead normal lives.
Anticonvulsants
Some people with symptoms of mania who do not benefit from or would prefer to avoid lithium have been found to respond to anticonvulsant medications commonly prescribed to treat seizures.
The anticonvulsant valproic acid ( Depakote, divalproex sodium ) is the main alternative therapy for bipolar disorder. It is as effective in non-rapid-cycling bipolar disorder as lithium and appears to be superior to lithium in rapid-cycling bipolar disorder. 2 Although valproic acid can cause gastrointestinal side effects, the incidence is low. Other adverse effects occasionally reported are headache, double vision, dizziness, anxiety, or confusion. Because in some cases valproic acid has caused liver dysfunction, liver function tests should be performed before therapy and at frequent intervals thereafter, particularly during the first 6 months of therapy.
Other anticonvulsants used for bipolar disorder include carbamazepine ( Tegretol ), lamotrigine ( Lamictal ), gabapentin ( Neurontin ), and topiramate ( Topamax ). The evidence for anticonvulsant effectiveness is stronger for acute mania than for long-term maintenance of bipolar disorder.
Most people who have bipolar disorder take more than one medication. Along with the mood stabilizer--lithium and/or an anticonvulsant--they may take a medication for accompanying agitation, anxiety, insomnia, or depression. It is important to continue taking the mood stabilizer when taking an antidepressant because research has shown that treatment with an antidepressant alone increases the risk that the patient will switch to mania or hypomania, or develop rapid cycling. Sometimes, when a bipolar patient is not responsive to other medications, an atypical antipsychotic medication is prescribed. Finding the best possible medication, or combination of medications, is of utmost importance to the patient and requires close monitoring by a doctor and strict adherence to the recommended treatment regimen.
Major depression, the kind of depression that will most likely benefit from treatment with medications, is more than just "the blues.” If the depression is recognized and treated, a person's quality of life can be greatly improved.
Antidepressants are used most often for serious depressions, but they can also be helpful for some milder depressions. Antidepressants are not "uppers" or stimulants, but rather take away or reduce the symptoms of depression and help depressed people feel the way they did before they became depressed.
The doctor chooses an antidepressant based on the individual's symptoms. Some people notice improvement in the first couple of weeks; but usually the medication must be taken regularly for at least 6 weeks and, in some cases, as many as 8 weeks before the full therapeutic effect occurs. If there is little or no change in symptoms after 6 or 8 weeks, the doctor may prescribe a different medication or add a second medication such as lithium, to augment the action of the original antidepressant. Because there is no way of knowing beforehand which medication will be effective, the doctor may have to prescribe first one and then another. To give a medication time to be effective and to prevent a relapse of the depression once the patient is responding to an antidepressant, the medication should be continued for 6 to 12 months, or in some cases longer, carefully following the doctor's instructions. When a patient and the doctor feel that medication can be discontinued, withdrawal should be discussed as to how best to taper off the medication gradually. Never discontinue medication without talking to the doctor about it. For those who have had several bouts of depression, long-term treatment with medication is the most effective means of preventing more episodes.
Dosage of antidepressants varies, depending on the type of drug and the person's body chemistry, age, and, sometimes, body weight. Traditionally, antidepressant dosages are started low and raised gradually over time until the desired effect is reached without the appearance of troublesome side effects. Newer antidepressants may be started at or near therapeutic doses.
Side effects of antidepressant medications.
Antidepressants may cause mild, and often temporary, side effects (sometimes referred to as adverse effects) in some people. Typically, these are not serious. However, any reactions or side effects that are unusual, annoying, or that interfere with functioning should be reported to the doctor immediately. The most common side effects of tricyclic antidepressants, and ways to deal with them, are as follows:
The newer antidepressants, including SSRIs, have different types of side effects, as follows:
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.
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.
