Miconazole nitrate cream should not be used for fire boils. Boils are bacterial infections of the hair follicles and their surrounding tissues, mostly caused by Staphylococcus aureus infections, and therefore need to be treated with antibiotic ointment, while miconazole nitrate cream is an antifungal drug, which is not able to kill the bacteria. The early stage of the fire boil will often be manifested as local redness, swelling and heat pain, can use erythromycin ointment, mupirocin ointment and other local application, has the effect of bactericidal pain, but allergic to the ingredients of the drug is prohibited, the use of drugs, if there is a rash, itching, and other adverse reactions need to be discontinued. However, if abscess has been formed, simply applying local medication cannot provide good relief and incision and drainage is needed. Fire boils should be under the guidance of a doctor, local medication patients should not self-medicate.
