Which of the following is a side effect of ceftriaxone?

Ceftriaxone, a broad-spectrum cephalosporin antibiotic, can indeed cause side effects, and nausea is one of the common gastrointestinal side effects associated with its use. This medication can disrupt the normal balance of gut flora, potentially leading to gastrointestinal disturbances, including nausea, vomiting, and diarrhea.

Nausea is a relatively frequent experience among patients taking various antibiotics as they may affect the digestive system and induce discomfort. Furthermore, gastrointestinal side effects like nausea may not only be a direct effect of the medication but can also be influenced by the individual's overall health status, the presence of other medications, or the specific infection being treated.

While anaphylaxis, hives, and difficulty breathing are also significant potential reactions to ceftriaxone, they are less common and are considered allergic reactions or serious adverse effects. These reactions usually occur in a smaller subset of patients who may have a known allergy to the medication or to similar antibiotic classes. Therefore, while they are serious concerns, they do not reflect the more common experiences associated with ceftriaxone, such as nausea.
