This medication should not be taken by individuals who are allergic to chlorzoxazone or acetaminophen. Due to the presence of acetaminophen, caution is necessary to avoid exceeding the daily maximum dosage when taking other products that contain acetaminophen, as this may lead to liver damage. Individuals with severe liver or kidney impairment, and those with a history of allergies should consult a healthcare professional before taking this medication. Women who are pregnant or may become pregnant should only take this medication if the benefits outweigh the risks, as its safety has not been established. If any signs of hypersensitivity such as rash, redness, or itching occur while taking this medication, use should be discontinued immediately, as rare cases of skin rash, bleeding, urine discoloration, severe swelling, or anaphylaxis may occur. If symptoms of liver dysfunction develop, this medication should be discontinued, as gastrointestinal disturbances or bleeding, drowsiness, dizziness, headaches, lethargy, and excessive excitement may occur as side effects. Caution is required when taking this medication with alcohol or central nervous system depressants, as side effects may be intensified. This medication should be stored out of the reach of children, protected from direct sunlight, and kept in a cool, dry place, and should not be transferred to another container to maintain quality.
