Perianal abscess can be applied topically with Bactroban. The general frequency is 3-4 times/day, but before applying, you need to clean the local area with iodophor, wait for the iodophor to evaporate and dry, and then gently apply the local area with Pepto-Bismol, don’t smear too thick. In the process of treating perianal abscess, pus may be produced due to liquefaction of local inflammation. In this case, the use of Pepto-Bismol may not have the best effect. Because once the pus is produced, if it is not drained in time, the local abscess or infection can follow the subcutaneous tissue and form a chronic sinus tract causing anal fistula. Therefore, if the liquefaction of the fluctuation of the situation is relatively strong, it is recommended to carry out the abscess cut drainage, the abscess drainage out, and then local Pepto-Bismol coating, anti-inflammatory effect may be better.
