Which statement by a client taking SSRIs indicates understanding of side effects?

The statement indicating an understanding of side effects is that increased sweating may occur while taking SSRIs. This is a recognized side effect of selective serotonin reuptake inhibitors. SSRIs work by increasing serotonin levels in the brain, which can affect various body systems, including those that regulate sweat production. Clients who are aware of potential side effects such as increased sweating demonstrate an understanding of the medication's effects on their body.

The other statements reflect misunderstandings about SSRIs. For example, while weight changes can occur, they can differ widely among individuals, and it is not accurate to state that weight will decrease; it can also increase. The notion of feeling more depressed is generally contrary to the intended effect of SSRIs, which is to alleviate symptoms of depression. Lastly, it is important for clients to understand that SSRIs usually take several weeks to show therapeutic effects, rather than feeling better within just a few days after starting the medication. Emphasizing awareness of side effects like increased sweating helps clients better manage their expectations and reports in conjunction with their treatment.
