Which side effect is commonly associated with the use of SSRIs?

Nausea is a well-documented side effect commonly associated with the use of selective serotonin reuptake inhibitors (SSRIs). These medications work by increasing the levels of serotonin in the brain, which can impact various bodily systems, including the gastrointestinal tract. As a result, patients may experience symptoms such as nausea, especially when they first start taking the medication or when the dosage is increased. This side effect is often transient, with many patients finding that it diminishes over time as their bodies adjust to the medication.

While hallucinations can occur with various psychiatric medications, they are not typical side effects of SSRIs and may indicate a serious reaction or underlying condition. Frequent urination is not a common side effect associated with SSRIs; rather, it can be related to other medications or health issues. Fatigue may occur in some patients but is generally less commonly reported compared to gastrointestinal symptoms like nausea. Thus, nausea stands out as a primary and frequently experienced side effect among those starting SSRIs.
