Erythromycin ointment belongs to macrolide antibiotics, which are used locally and have a therapeutic effect on certain types of anal itching: first, anal sinusitis and anal papillitis, which are bacterial infections at the anal orifice, and the application of erythromycin ointment has a certain effect. Second, perianal eczema can be treated by applying erythromycin ointment, which has the effect of anti-inflammatory and edema reduction. Third, if the anal itching is caused by anal fistula, it can be seen that there is swelling and swelling around the anal area, and pus may overflow when pressed. Erythromycin ointment cannot enter the fistula to achieve a therapeutic effect, so the application of antibiotics is ineffective.

It is best not to blindly apply erythromycin ointment for the treatment of anal itching. First, identify the cause of the disease and then use medication. Erythromycin ointment has a good effect on anti-inflammatory, antibacterial, and anti-itching, and can reasonably treat anal fissures and perianal eczema, and the symptoms of itching and swelling. However, for other perianal diseases such as hemorrhoids and rectal polyps, there is no significant effect on the symptoms of itching and pain. Especially, erythromycin ointment contains a certain amount of hormone ingredients, and long-term application may cause allergic reactions of the skin and exacerbation of hemorrhoids and other diseases.

Therefore, for the symptoms of anal itching at the anal orifice, it is necessary to identify the cause of the disease first before using relevant ointments for treatment, especially before using erythromycin ointment. It is best to clean the anal orifice with warm water first.

Patients with anal itching can also apply erythromycin ointment externally. As it is common for hemorrhoids or anal fissures to recur, the infection of some soft tissues around the anus has occurred due to repeated attacks. It is necessary to maintain some dryness after cleaning the area around the anus. Apply erythromycin ointment thinly to the superficial layer of the wound, with a thickness of 1-2mm, and use sterile medical dressings to tie it up, which has the effects of anti-inflammatory, edema reduction, and itching relief. In addition, hemorrhoid ointment can also be applied externally, which can also alleviate the condition to a certain extent. Pay attention not to drink alcohol, smoke, or eat spicy and刺激性 foods during the acute stage, as these bad habits are also very likely to exacerbate the condition of itching, causing some capillaries to dilate, and the patient’s symptoms to worsen.
