Precautions

This medication should not be taken by individuals who regularly consume more than three drinks a day without first consulting a doctor or pharmacist, as there is a risk of liver damage when taken with alcohol. Acetaminophen contained in this medicine can cause serious skin reactions, although this is very rare. If a rash or hypersensitivity reaction occurs, stop taking it immediately and consult a healthcare professional. The maximum daily dose of acetaminophen should not exceed 4,000mg, and this medication should not be taken in conjunction with other medications containing acetaminophen. Overdose can lead to liver damage. Individuals with allergies to this medication or its components, those who have experienced asthma episodes after taking similar medications, and infants under 3 months of age should avoid taking this medication. During use, it is advisable not to take other antipyretic analgesics, cold medications, or sedatives. Children suspected of having chickenpox or influenza, individuals with allergic predispositions or previous allergic reactions to medications, patients with liver, kidney, or heart conditions, those with hypertension or diabetes, the elderly, pregnant or breastfeeding women, and those currently taking other medications should consult a healthcare provider before use. If serious symptoms like hives, difficulty breathing, severe skin rash, or jaundice occur after taking this medication, discontinue use immediately and consult a doctor. Children under 2 years of age should not take this medication except in special cases, and if necessary, should be under a physician's care. It is important to strictly follow the prescribed dosage and duration, avoid long-term use, and monitor children while administering the medication under parental supervision. Avoid alcohol during use, and be cautious about using this medication with specific other drugs, as it may impair the metabolism of acetaminophen. Concurrent use with certain antibiotics (e.g., flucloxacillin) can rarely cause severe metabolic acidosis; consult a healthcare professional in this case as well. When storing this medication, keep it out of the reach of children, avoid direct sunlight, and store in a cool, dry place in a sealed container.
