What side effect should a nurse discuss with clients starting an SSRI like citalopram?

When starting treatment with an SSRI such as citalopram, it is important to discuss potential gastrointestinal disturbances as a common side effect. SSRIs can affect neurotransmitter levels in the gut, leading to symptoms such as nausea, diarrhea, or constipation. These gastrointestinal issues often occur as the body adjusts to the medication and may improve over time.

In contrast, while increased energy can be a long-term benefit once the medication takes effect, it typically does not occur immediately and is not felt in the initial stages of treatment. Weight loss is not a common side effect associated with SSRIs; many individuals may experience weight gain instead, or no significant change in weight. Rapid heart rate is also not a typical side effect of SSRIs; instead, they may influence heart rate and blood pressure, but notable cardiovascular effects are less common. Therefore, highlighting gastrointestinal disturbances provides clients with a more accurate expectation of what to anticipate when starting citalopram therapy.
