Gastrointestinal issues may lead to nausea, vomiting, abdominal pain, or diarrhea, and if symptoms are severe, consultation with a physician is required.

Pregnant women should take this medication cautiously under medical supervision as limited data is available, and nursing mothers should also be careful as it may affect the baby. Children and the elderly may require dosage adjustments due to potential increases in drug concentration from reduced kidney function.
