Can I apply fusidic acid cream for mouth sores caused by excessive internal heat?

When blisters develop on the mouth due to excessive internal heat, fusidic acid cream may be applied in appropriate amounts under a doctor's guidance for treatment. Fusidic acid cream is a topical antibiotic ointment used to treat skin infections caused by Gram-positive cocci and may help alleviate blistering symptoms of the lips caused by bacterial infections. It is important to note that if the blistering is caused by a viral infection, fusidic acid cream may not be suitable, as this medication is ineffective against viruses. Before using fusidic acid cream, it is recommended to first rule out the possibility of an allergic reaction to the medication and ensure that the blistering is indeed caused by a bacterial infection. Additionally, if discomfort such as burning or redness occurs during application, the medication should be discontinued immediately, and the affected area should be washed thoroughly. Besides medication, maintaining good oral hygiene, avoiding spicy and irritating foods, and drinking more water can also help relieve symptoms of blisters caused by excessive internal heat. If symptoms persist or worsen, prompt medical consultation is recommended for more professional diagnosis and treatment.
