Bactroban, also known as mupirocin ointment, is a topical topical antibiotic that is mainly indicated for skin infections caused by gram-positive cocci, such as primary skin infections like impetigo, boils, folliculitis and eczema co-infections. Bactrim is a topical topical drug and generally has no adverse reactions. Common adverse reactions are local burning sensation, occasional itching, erythema, stinging sensation or dryness, etc. It is usually not necessary to discontinue the drug. If severe skin irritation occurs, discontinue use, wipe off the ointment and seek medical attention as soon as possible. Rarely, it may cause inflammation of the colon, resulting in diarrhea, often with blood and mucus, stomach pain, and fever. In very rare cases, severe allergic reactions may occur, including rash, swelling, sometimes on the face or mouth, and in severe cases may cause difficulty in breathing, as well as possible deficiency or loss of consciousness and systemic allergic reactions. Therefore, you need to observe the drug when administering it and seek medical attention for any abnormal manifestations.
