Antidepressants can cause withdrawal symptoms if stopped abruptly or tapered too quickly, especially with certain types of antidepressants such as SSRIs (selective serotonin reuptake inhibitors) and SNRIs (serotonin-norepinephrine reuptake inhibitors). Withdrawal symptoms may include dizziness, nausea, headaches, insomnia, anxiety, irritability, and flu-like symptoms. It is important to work with a healthcare professional to slowly taper off antidepressants to minimize the risk of withdrawal symptoms.
