Can erythromycin ointment be used for hemorrhoids?

Generally, erythromycin ointment can be used for hemorrhoids when bacterial infection is present, but should not be used when there is no infection or when symptoms are mild and uncomplicated. If abnormalities occur, prompt medical attention is recommended. Detailed explanation is as follows:

If local symptoms such as redness, swelling, increased pain, surface ulceration, or pus discharge—indicative of bacterial infection—are present, applying erythromycin ointment can exert antibacterial and anti-inflammatory effects, inhibit local bacterial proliferation, alleviate infection symptoms, and promote healing of damaged mucosa. In such cases, proper application under medical guidance can effectively relieve discomfort caused by infection and aid in recovery.

When there are no signs of infection and only symptoms such as swelling, itching, or minor rectal bleeding are present, erythromycin ointment is not recommended. In these cases, bacterial infection is absent, and the indiscriminate use of antibiotic ointments will not relieve symptoms. It may instead disrupt the normal bacterial balance around the anus and cause other discomforts. These simple cases of hemorrhoids are better managed with warm water sitz baths or specific hemorrhoid medications to alleviate symptoms.

Before using erythromycin ointment, it is important to confirm whether an infection exists and to strictly follow medical advice regarding medication. If symptoms do not improve after use or adverse reactions such as allergies occur, the medication should be discontinued immediately and medical attention sought. Self-medication without medical supervision is not advised.
