Explanation:
GI upset from this sulfonamide antibiotic is common, and diarrhea is the most frequent adverse effect. Its broad action disrupts normal intestinal flora and can irritate the GI tract, leading to loose stools more often than nausea, dizziness, or headaches. Encourage fluids and monitor for persistent or severe diarrhea, especially with fever or abdominal pain, which could indicate antibiotic-associated colitis.
