Can A Placebo Replace Your Antidepressant
Media outlets were abuzz early this year with the news that antidepressant drugs don’t get rid of depression. The source was a Jan. 6, 2010, report in the prestigious Journal of the American Medical Association analyzing data from six clinical trials of antidepressants conducted between 1980 and 2009, involving 718 patients. The study concluded that when people with mild or even moderate depression took a pill, their symptoms improved. The kicker: The improvement was the same, on average, whether the pill was a real drug or a lookalike placebo. Only among people with more severe symptoms did the real drugs have an edge over the placebo.
Studies like those make great headlines. Far more complicated is how to apply the findings in real life. You can’t diagnose or track depression with a blood test or an X-ray. Assessing improvement relies completely on the patient’s subjective reporting of his or her state of mind. Plenty of studies have shown that the drugs work, though placebo effects are notoriously high in antidepressant trials, and the drugs’ advantage over placebos is usually modest.
If you’re not sure you need an antidepressant any more, talk with your doctor about reducing the dose or weaning off of it. Never stop an antidepressant suddenly or on your own; you may be risking severe withdrawal symptoms.
Will I Need To Use This Drug Long Term
Pristiq is meant to be used as a long-term treatment. Clinical guidelines for treatment recommend that you keep taking your antidepressant for 4 to 9 months after your depression symptoms improve. Staying on treatment helps reduce your risk of depression coming back.
In some people, depression is more likely to come back after they stop taking antidepressants. People at higher risk of this happening are those who’ve had several episodes of depression, or those with a family history of psychiatric illness.
If you have these risk factors, it’s recommended that you take antidepressants for a longer time before stopping the medications. This helps lower your risk of your depression coming back.
If you and your doctor determine that Pristiq is safe and effective for your depression, you may take the drug long term.

Desvenlafaxine How Does Did It Work For You
I’ve recently been prescribed Pristiq after trying Citalopram . On the Citalopram my mood improved slightly – felt kind of numb emotionally, but physically I felt horrible. Headache, anxious, pounding heart, constantly hungry, didn’t sleep well, felt as if I had been poisoned, just overall blah. I haven’t started taking the Pristiq as I understand it’s more difficult to stop and I dread the potential side effects. I was diagnosed with clinical depression in my early twenties and am now in my late fifties. I have tried Paxil, Welbutrin, and Prozac in the past. Over the past six years, my depression has been worse than ever. I’m interested in hearing from folks that have experience taking Pristiq. Thanks in advance.
EDIT: Ah, but good news – my doctor cut the Pristiq from 100mg to 50mg when I started the Wellbutrin. Zero side effects from stepping down. So there may be a nice tapering method to get off it.
Selective Serotonin Reuptake Inhibitors
These include fluoxetine , paroxetine , sertraline , fluvoxamine , citalopram , and escitalopram . They tend to be the first line choice for multiple anxiety disorders and depression. They are technically classified as antidepressants .
Sertraline is FDA approved for multiple conditions including: Major Depression, OCD, PTSD, Social Anxiety, Panic Disorder, and Premenstrual Dysphoric Disorder. While not all SSRIs have this many FDA approved indications, we often use the other ones for the same conditions. Pharmacy companies do not always bother pursuing FDA approvals due to cost reasons and the realization that the meds will be used off-label. It is completely legal and ethical to use medications for off-label purposes, but ideally the patient and provider should have a discussion about this first.
While SSRIs can have an immediate effect, the full effect can take anywhere from 3-8 weeks depending on the person. They are generic and cheap. I tend to prefer generic meds b/c they have been around longer with a proven track record, and the risks are known too . This is my style, and there is certainly nothing wrong with those who do prescriber newer meds .
While they are overall fairly well tolerated and arguably with less side effects than older classes of antidepressants, some people may be more sensitive to side effects of this class and may do better with older classes like tricyclic antidepressants or MAOIs .
