Which of the following is a common adverse effect of Fexofenadine?

• A. Nausea
• B. Excessive appetite
• C. Weight gain
• D. Insomnia

Answer: (A)

Fexofenadine, an antihistamine used primarily to treat allergic symptoms, is generally considered to have a favorable side effect profile compared to first-generation antihistamines. However, nausea can occasionally occur as an adverse effect. This is particularly relevant as some patients may experience gastrointestinal disturbances when taking medications that affect histamine pathways. Understanding the nature of fexofenadine’s action helps clarify this adverse effect. By blocking H1 histamine receptors, fexofenadine can influence various physiological responses, including those related to the gastrointestinal system, potentially leading to nausea in some individuals. Other options listed, such as excessive appetite, weight gain, and insomnia, are not commonly associated with fexofenadine use. These side effects are more typical of other medications or conditions rather than a direct result of fexofenadine administration, making nausea the most fitting answer concerning its adverse effects.
