Individuals with pre-existing conditions, such as liver disease, may have a lower maximum dose and are advised to discuss use with a healthcare professional.

Q：この薬はアレルギー反応や重篤な皮膚反応を引き起こすことがありますか？
According to official regulatory sources, acetaminophen has been associated rarely with serious skin reactions, including Stevens-Johnson Syndrome (SJS), Toxic Epidermal Necrolysis (TEN), and Acute Generalized Exanthematous Pustulosis (AGEP), which can be fatal.

Q：この薬はどのように保管すればよいですか？
