Precautions

This medicine may pose a risk of liver damage, so individuals who regularly consume more than three glasses of alcohol per day should consult a doctor or pharmacist before taking it. The acetaminophen component in this medicine can rarely cause severe skin reactions, so if you develop a rash or hypersensitivity reaction, you must stop taking it immediately. Taking more than 4,000 mg of acetaminophen per day can lead to liver damage, so do not take this medicine alongside other products containing acetaminophen. Do not take this medicine if you have an allergy to it or its components, or if you have previously experienced allergic reactions, such as asthma. Infants under 3 months of age, breastfeeding women, and individuals taking certain medications such as specific antidepressants or antipsychotics should not use this medicine or must consult a professional before use. It is safe to avoid taking cough medicines, other cold medicines, antipyretics, sedatives, and antihistamines while using this medicine. Consult a doctor before taking this medicine if the patient is an infant infected with chickenpox or influenza, a child under 15 years of age, has allergies, or has chronic diseases such as liver or kidney disease. If you experience symptoms such as rash, itching, nausea, vomiting, dizziness, or insomnia during treatment, stop taking the medicine immediately and consult a professional. In particular, if serious symptoms like hives, difficulty breathing, or severe skin rash occur, seek emergency treatment immediately. This medicine should not be used in children under 2 years old, and a doctor's consultation is necessary in urgent cases. Make sure to follow the prescribed dosage and duration, and avoid long-term continuous use. When administered to children, a guardian must supervise, and avoid alcohol consumption, as drowsiness may occur, which necessitates refraining from driving or operating machinery. Taking this medicine concurrently with certain medications may slow the breakdown of acetaminophen, necessitating caution during combined use. Store this medicine out of reach of children, away from direct sunlight, in a cool and dry place. For quality maintenance, it is advisable not to transfer it to another container.
