You can choose cephalosporin antibiotics for perianal abscess, and you can also take antibacterial and anti-inflammatory drugs such as metronidazole, amoxicillin or roxithromycin. But when using drugs should be strictly in accordance with the doctor’s instructions or instructions for the dosage of drugs, for the weight to calculate the amount of drugs should also be strictly calculated. It is recommended to have an examination in the hospital before using the medication to clarify the curative factors of the perianal abscess and to use the specific antibiotic medication for a more obvious effect. There are many types of perianal abscesses. If a perianal abscess is caused by an infection of intestinal origin and is accompanied by a small amount of bleeding, the effect of using anti-inflammatory drugs alone is not obvious and the abscess site needs to be incised and drained. In the process of medication, you should not rely on drugs for a long time, you should follow a course of treatment, and if the symptoms are not relieved after a period of time, you should immediately go to the hospital for medical treatment and adjust the medication with your situation.
