Pregnant or breastfeeding women should consult a professional before taking this medication as the effects on the fetus or newborn are not fully understood. In children or elderly individuals, the dosage should be adjusted according to renal function, and if any unusual symptoms occur, immediate consultation with medical personnel is necessary.
