Vaginal pain after using Sophora flavescens gel two months postpartum

Two months postpartum, pain at the vaginal opening after using Sophora flavescens gel may be caused by physiological factors or pathological factors such as drug allergy or local infection. Symptomatic treatment should be based on specific circumstances. The detailed analysis is as follows:

I. Physiological Factors

Sophora flavescens gel is a topical medication whose main ingredient is total alkaloids of Sophora flavescens. It is a water-soluble gel with antibacterial and anti-inflammatory properties. During application, the active ingredients may irritate the skin surface, causing pain—a normal phenomenon. Usually, this symptom gradually diminishes after continued use for a period of time.

II. Pathological Factors

1. Drug Allergy

If the patient has an allergic constitution and is sensitive to components in Sophora flavescens gel, applying the medication may trigger a local mucosal allergic reaction. This increases the activity of mast cells, leading to the release of inflammatory substances, resulting in redness, swelling, and itching of the local skin, thus causing these symptoms. It is recommended to immediately discontinue the drug and, under medical guidance, take antiallergic medications such as loratadine tablets or levocetirizine hydrochloride tablets.

2. Local Infection

If there is an open wound or ulceration at the vaginal opening, direct contact with Sophora flavescens gel may cause abnormal irritation, worsening local soft tissue swelling and potentially leading to infection, thereby impairing therapeutic effectiveness. It is recommended to clean the area with plain water in daily care to promote wound healing.

In addition, other possible causes include drug overdose, vaginitis, or cervical ulceration. Patients are advised to use medication only under the guidance of a physician and avoid blind or unsupervised use.
