Precautions

This drug should not be used by individuals allergic to certain ingredients or children under 30 months of age. Additionally, it should not be applied to sensitive areas such as the eyes, around the eyes, or mucous membranes. It is also advisable to avoid use on areas with eczema or dermatitis due to poison ivy, wounds, or skin that is very sensitive. Individuals who have experienced allergic reactions to medications or cosmetics or have a family history of allergies should consult a doctor or pharmacist before using this medication. If you have severe moist or macerated skin conditions, are receiving other treatments, have circulatory diseases or diabetes, or are a child, pregnant or breastfeeding woman, it is necessary to consult a professional. If any symptoms such as rash, redness, swelling, itching, or pain appear while using this drug, discontinue use immediately and consult a professional. If symptoms do not improve after 5 to 6 days of use, stop using and consult a doctor. Follow the prescribed dosage and administration strictly, and when used by children, a guardian should supervise. This drug is a topical preparation for external application only and should not be ingested or inhaled. Take care to avoid contact with the eyes, and if it does come into contact, wash thoroughly with clean water and seek ophthalmologic care if symptoms are severe. Avoid touching the eyes or mucous membranes with hands contaminated with this medication, and wash hands thoroughly after handling. Do not tightly wrap the area where the medication is applied, and be careful to avoid exposure to hot water or heat. If the application area comes into contact with water, it may cause irritation, so caution is necessary. It is advisable not to continuously use this medication on the same area for individuals with sensitive skin. Excessive absorption of the methyl salicylate ingredient through the skin can lead to toxicity symptoms, so do not use it for a long time on large areas. This drug should be stored out of reach of children and kept in a tightly closed container away from direct sunlight in a cool, dry place. Transferring the medication to another container may lead to misuse or quality deterioration, so it is safest to keep it in its original container.
