Not only does it take time to get an accurate depression diagnosis, finding the right medication to treat depression can be a complicated, delicate process. Someone may have a serious medical problem, such as heart disease or liver or kidney disease, that could make some antidepressants unsafe. The antidepressant could be ineffective for you, the dose inadequate, there hasn’t been enough time to see an effect, or side-effects are too bothersome -- leading to a failure of treatment.
As you approach taking antidepressants to treat depression, it is important to keep these points in mind:
A controversial new study suggests the widely prescribed antidepressantsProzac, Paxil, and Effexor work no better than placebo for most patients who take them, and many depression experts now cry foul.
Only 30% of people with depression go into full remission after taking their first course of antidepressants. That’s according to a 2006 study funded by the National Institutes of Health. Those who got better were more likely to be taking slightly higher doses for longer periods.
Some antidepressants work better for certain individuals than others. It's not uncommon to try different depression medicines during treatment.
Some people need more than one medicine for depression treatment.
Antidepressants carry a boxed warning about increased risk compared to placebo for suicidal thinking and behavior in children, adolescents, and young adults 18-24 years old.
Working with your doctor, you can weigh the risks and benefits of treatment and optimize the use of medication that best relieves your symptoms.
What is an antidepressant?
Antidepressants, in combination with psychotherapy, are often the first treatment people get for depression. If one antidepressant doesn't work well, you might try another drug of the same class or a different class of depression medicines altogether. Your doctor might also try changing the dose. In some cases, your doctor might recommend taking more than one medication for your depression.
What are the different types of antidepressants?
Here are the main types of antidepressants along with brand names:
Selective serotonin reuptake inhibitors (SSRIs) were launched in the mid to late 1980s. This generation of antidepressants is now the most common class used for depression. Examples include citalopram (Celexa), escitalopram (Lexapro), paroxetine (Paxil, Pexeva), fluoxetine (Prozac, Sarafem), and sertraline (Zoloft). Another SSRI, Viibryd, was approved in early 2011. Side effects are generally mild, but can be bothersome in some people. They include stomach upset, sexual problems, fatigue, dizziness, insomnia, weight change, and headaches.
Serotonin and norepinephrine reuptake inhibitors (SNRIs) are a newer type of antidepressant. This class includes venlafaxine (Effexor), desvenlafaxine (Pristiq), and duloxetine (Cymbalta). Side effects include upset stomach, insomnia, sexual problems, anxiety, dizziness, and fatigue.
Tricyclic antidepressants (TCAs) were some of the first medications used to treat depression. Examples are amitriptyline (Elavil), desipramine (Norpramin, Pertofrane), doxepin (Adapin, Sinequan), imipramine (Tofranil), nortriptyline (Aventyl, Pamelor), protriptyline (Vivactil), and trimipramine (Surmontil). Side effects include stomach upset, dizziness, dry mouth, changes in blood pressure, changes in blood sugar levels, and nausea.
Monoamine oxidase inhibitors (MAOIs) were among the earliest treatments for depression. The MAOIs block an enzyme, monoamine oxidase. Examples are phenelzine (Nardil), tranylcypromine (Parnate) , isocarboxazid (Marplan), and selegiline (EMSAM). Although MAOIs work well, they're not prescribed very often because of the risk of dangerous reactions. They can cause serious interactions with other medications and certain foods. Foods that can negatively react with the MAOIs include aged cheese, wines, chocolate, bananas, and chicken liver.
Other medications: Bupropion (Wellbutrin, Aplenzin) is different than other antidepressants and only weakly affects the brain chemicals that other antidepressants influence. Side effects are usually mild, including upset stomach, headache, insomnia, and anxiety. Bupropion may be less likely to cause sexual side effects than other antidepressants.
Mirtazapine (Remeron) is usually taken at bedtime. Side effects are usually mild and include sleepiness, weight gain, elevated triglycerides, and dizziness.
Trazodone (Desyrel) is usually taken with food to reduce chance for stomach upset. Other side effects include drowsiness, dizziness, constipation, dry mouth, and blurry vision.
