Caution is required for these patients due to the risk of decreased white blood cell or platelet counts. Additionally, patients taking certain medications such as steroids, antibiotics, anticancer drugs, and azole antifungals should be cautious as this drug may reduce blood cell counts.

Children, especially those under 15 years old, and elderly individuals over 80 years old should avoid this medication or use it very cautiously as its safety has not been sufficiently confirmed.
