Going off SSRIs without tapering off of them under the direction of a psychiatrist can cause antidepressant withdrawal symptoms. Unlike withdrawal from a narcotic or powerfully addictive drug, these withdrawal symptoms aren’t regarded as medically dangerous, but they can be downright uncomfortable. They occur because the brain’s neurons haven’t had the chance to adapt to the suddenly reduced level of neurotransmitters. Some people experience headaches or increased irritability. Other symptoms can include nausea, insomnia, tiredness, and/or anxiety. In severe cases, a person might experience a range of flu-like symptoms that include chills and achiness.
Withdrawal Symptoms from SSRIs
Immediate discontinuation of SSRIs can also produce symptoms of depression—some quite severe. Some people may even experience suicidal thoughts. This can be confusing because patients may not be able to tell if their depression is merely part of the withdrawal process or a return of their clinical depressive symptoms. According to medical practitioners, if depressive symptoms show up within days or possibly even weeks of discontinuation, they are most likely associated with SSRI withdrawal. If the symptoms develop later or gradually, they may constitute a relapse of the depression.
Ultimately, these withdrawal symptoms will improve with time, but they can be unpleasant for days and possibly even weeks. In time, the brain readjusts and people should experience a return to their normal state. If depressive symptoms do arise and gradually worsen, it’s best to consult a psychiatrist or doctor, if they don’t improve within a few weeks or if they become severe.
