Abrupt discontinuation of certain antidepressant medications can lead to withdrawal symptoms because the body has adapted to the presence of the medication. Many antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) and some other classes, can cause physical dependence. When the medication is suddenly stopped, the neurotransmitter levels, which have been altered by the drug, can fluctuate dramatically, leading to a variety of withdrawal symptoms. These symptoms may include nausea, headaches, fatigue, irritability, and mood disturbances, among others.

In contrast, the other potential responses do not accurately capture the risks associated with discontinuing antidepressant medications. Heart palpitations and hyperactivity are not typical withdrawal symptoms and can occur for different reasons unrelated to the abrupt stopping of antidepressants. Increased libido is also not associated with withdrawal; in fact, some antidepressants can lead to decreased libido while on the medication. Understanding the risks involved with sudden discontinuation is crucial for ensuring safe and effective management of antidepressant medication therapy.
