How many days does it take for erythromycin ointment to resolve a Bartholin's gland abscess?
Under normal circumstances, vestibular gland abscess symptoms may subside after applying erythromycin for 5–7 days. If symptoms do not improve or worsen, prompt medical attention is recommended. Detailed analysis is as follows:

If the abscess is mild with a limited infection area and the patient has good immune resistance, regular application of erythromycin—combined with maintaining local cleanliness and dryness and avoiding friction or irritation—can effectively exert its antibacterial and anti-inflammatory effects. In such cases, the abscess may gradually shrink and resolve within about 5–7 days, and discomfort such as pain will also diminish accordingly.
However, if the abscess is severe, the infection is extensive, or there is significant pus accumulation, topical erythromycin alone may not adequately control the infection. In these cases, symptoms may show no obvious improvement after 5–7 days; instead, the abscess may enlarge and pain may intensify. Some patients may even develop systemic symptoms such as fever. Timely medical evaluation and further treatment are necessary under these circumstances.
If the abscess persists, pain worsens, or fever develops, do not delay—seek immediate medical care at a hospital.
