Precautions

People with a predisposition to allergic reactions should consult a doctor or pharmacist before taking this medication. Those who have previously experienced allergic symptoms such as fever, rash, joint pain, or itching due to medications should also exercise caution. Patients with liver or kidney function issues, thyroid disorders, diabetes, those with high fever, or individuals in poor health should use this medication cautiously. Women who are pregnant, may become pregnant, or are nursing should consult a healthcare professional before taking this medication. If taking other medications, consult a doctor or pharmacist regarding potential drug interactions. Patients with high blood pressure or the elderly should be particularly careful when using this medication. It is important for patients with heart or kidney problems to consult a healthcare professional before taking this medication. Patients with swelling or those currently receiving medical treatment should seek professional guidance before taking this medication. If rash, reddening of the skin, nausea, vomiting, loss of appetite, dizziness, or headaches occur, discontinue use immediately and consult a professional. If urine output decreases, the face, hands, or feet swell, eyelids become heavy, hands feel stiff, blood pressure rises, or headaches occur, stop taking the medication and consult a doctor. Long-term use may decrease blood potassium levels due to the licorice component, which can raise blood pressure or cause body swelling, so regular blood tests are necessary and should be discontinued if abnormalities are detected. If symptoms such as muscle weakness, limb spasms, or paralysis due to hypokalemia occur, stop taking the medication immediately and seek professional care. The prescribed dosage and administration must be strictly followed, and caregiver supervision is necessary when administering to children. If symptoms do not improve after repeated doses, discontinue use and consult a doctor or pharmacist. Use with potassium-containing agents, medications containing licorice, or certain diuretics increases the risk of side effects, so caution is needed. It is safest not to take with other cough medications, cold medicines, antihistamines, sedatives, or alcohol. Do not administer to infants under 3 months old and avoid use in infants over 3 months but under 1 year old unless in special cases.
