Which Antidepressants Can Cause Negative Mental Health Symptoms?
Over the years, multiple antidepressant drugs have been created by the pharmaceutical industry with the intent of relieving symptoms of depression, anxiety, PTSD, OCD, and others 21Taking an antidepressant can cause drastic changes in the brain, especially once you have been taking the medication for four to six weeks. Antidepressants were developed to create artificially elevated levels of the neurotransmitters that may improve mood, like serotonin and norepinephrine, even though the nearly 50-year-old hypothesis that depression is directly related to serotonin deficiencies has never been proven. Citation #2]
The two major classes of modern antidepressants were both designed to artificially modulate the body’s levels of serotonin and norepinephrine. Selective serotonin reuptake inhibitors (SSRIs) are meant to prevent cells from absorbing serotonin (reuptake) before it can be used by the brain. Serotonin and norepinephrine reuptake inhibitors (SNRIs) prevent the reuptake of both these critical neurotransmitters. While this theoretically increases the serotonin available to the brain, evidence suggests that medications designed to boost serotonin levels may actually make any existing deficiency even worse. 3
This may be because the body and brain have become accustomed to artificially elevated neurotransmitter levels, reducing natural production and presenting issues when the medication ceases. In fact, any antidepressant can result in withdrawal symptoms if an individual suddenly stops taking the medication.
SSRIs that can cause negative symptoms when ceased abruptly include:
- fluvoxamine (Luvox)
- citalopram (Celexa)
- fluoxetine (Prozac)
- escitalopram (Lexapro)
- sertraline (Zoloft)
- Paroxetine (Paxil)
SNRIs may include:
- Duloxetine (Cymbalta)
- Venlafaxine (Effexor)
- Milnacipran (Savella)
- Levomilnacipran (Fetzima)
Antidepressant Discontinuation Syndrome
If you suddenly stop using antidepressant medication, you will likely begin to experience physical symptoms, as mentioned above. These symptoms, when coupled with the “brain zaps” many people describe when discontinuing antidepressants, are hallmarks of a condition known as antidepressant discontinuation syndrome. 4
The fact that this condition has a name leaves many people wondering, is there such a thing as antidepressant withdrawal? Yes, antidepressant discontinuation syndrome is another way of describing antidepressant withdrawal, and if you are experiencing these symptoms after abruptly stopping your antidepressant, it is a sign that you are in withdrawal. These symptoms can be experienced for several weeks after stopping an antidepressant.
Along with the dangerous side effects can come the temptation to resume using antidepressants to stave off withdrawal symptoms. This is similar to the way people with substance use disorders experience a strong desire to keep using a substance to avoid experiencing withdrawal. While antidepressants do not affect the brain in the same way as an illicit street drug, the brain can grow dependent on the artificially elevated neurotransmitter levels they provide. That means that removing them abruptly can cause serious side effects.
Psychological Dangers of Abruptly Stopping Antidepressants

Abruptly ceasing a medication that modulates mood swings and depression can cause several dangerous psychological symptoms in addition to physical symptoms.
For example, you may experience: 4
- Mood swings
- Feelings of hopelessness
- Mania
- Irritability
- Anger
- Disorientation
- Memory issues
- Psychosis
In general, depression and other original symptoms can quickly return after abruptly ceasing antidepressant use. The risk of mania may mean you’ll experience more extreme highs and lows than you did before taking antidepressants, which can serve to reduce your stamina and affect the amount of activity you are able to do in a day.
Heightened anger and irritability may or may not result in physical violence, and disorientation and memory loss can dramatically affect your ability to accomplish daily tasks. One of the most serious side effects is psychosis, where you are unaware of what is happening in reality.
Most significant, however, is the increased danger of developing suicidal thoughts, which has triggered the requirement for a black box warning on all antidepressant medications. If you are having suicidal thoughts, take action right away.
