Precautions

This medication may pose a risk of liver damage if taken by individuals who regularly consume more than three drinks per day, so consultation with a doctor or pharmacist is essential. This medication contains acetaminophen, and it is important to be cautious as taking it with other acetaminophen products may exceed the maximum daily dosage of 4,000mg, leading to potential liver damage. This medication should not be taken by individuals allergic to specific ingredients, especially those with hypersensitivity to chlorzoxazone or acetaminophen. Patients with severe liver or kidney dysfunction and those with a history of allergies should exercise increased caution when taking this medication. If symptoms of an allergic reaction such as hives, skin redness, or itching occur during use, the medication should be discontinued immediately. Rarely, skin rash or bleeding, changes in urine color, severe swelling, or anaphylactic reactions may occur, requiring vigilance. This medication can cause liver damage, so if there are signs of liver dysfunction, it should be stopped. Occasionally, gastrointestinal disturbances or rare gastrointestinal bleeding may occur, so be attentive to digestive symptoms. While taking this medication, neurological and psychiatric symptoms such as drowsiness, dizziness, headache, lethargy, and excessive excitement may occur; therefore, caution is necessary when driving or operating machinery. For women who are pregnant or may become pregnant, the safety of this medication is uncertain; thus it should only be used when it is determined that the benefits of treatment outweigh the risks.
