Vaginitis in Banpo: why it keeps coming back even with pharmacy medication

Vaginitis often doesn't resolve after a single episode; instead, it tends to recur after seeming to improve, which can be emotionally draining. If you experience frequent recurrences despite using over-the-counter vaginal suppositories, it's highly likely that the type of vaginitis has been misidentified.

Why Vaginitis Recur Even with Over-the-Counter Medications

Have you ever bought and used vaginal suppositories from a pharmacy because you suddenly had increased discharge, itching, or an unusual odor? It's very common for symptoms to seem to improve at first, only to return, making you wonder if you should visit a clinic.

There's a structural reason for recurrent vaginitis. Vaginitis is broadly categorized into three types, and each type responds to different medications. Over-the-counter vaginal suppositories often target candidal (yeast) vaginitis. Repeatedly using the same medication for bacterial or trichomonal vaginitis can disrupt the balance of normal vaginal flora, potentially leading to more frequent recurrences.

In our clinic, we see many patients who have disrupted their vaginal flora balance by repeatedly using the same medication. The key is that even if symptoms appear similar, the medication needed will differ if the underlying cause is different.

Vaginitis Requires Different Medications Depending on the Type

It's easy to think of vaginitis simply as itching and excessive discharge, but the nature of symptoms and the appropriate treatment vary depending on the causative pathogen. You can get an idea of the type based on the characteristics of the discharge.

However, symptoms can overlap, and repeated self-treatment without testing can lead to resistance or prolonged symptoms. It's safer to first identify the cause through Vaginitis & STI Care.

Why Over-the-Counter Medications Might Not Work for Bacterial Vaginosis

Bacterial vaginosis is a relatively common type. It occurs when beneficial lactobacilli decrease and anaerobic bacteria increase in the vagina, often appearing after excessive vaginal douching, weakened immunity, or antibiotic use.

• Grayish-white or yellowish thin discharge
• Fishy odor, tending to be more pronounced after sexual intercourse
• Itching is relatively less severe

Treatment often requires a prescription for metronidazole-based antibiotics, and over-the-counter vaginal suppositories alone may not be as effective as expected. Completing a full course of prescribed medication for a sufficient period helps reduce the likelihood of recurrence. If you're concerned about recurrent discharge, we recommend exploring Recurring Hygiene Issues.

Candidal Vaginitis is Characterized by Prominent Itching

This type occurs when Candida (yeast) overgrows, often recurring after antibiotic use, during hot seasons, or when frequently wearing tight, synthetic underwear.

• White, cottage cheese-like discharge, usually with little to no odor
• Intense itching and burning of the vulva
• Stinging sensation during urination

It is treated with oral antifungals or vaginal suppositories. If it recurs multiple times a year, a period of maintenance therapy may be helpful. Since there are individual differences, it's best to discuss the frequency of recurrence with your healthcare provider.

Trichomonal Vaginitis Requires Partner Treatment

Caused by Trichomonas protozoa infection, primarily transmitted through sexual contact.

• Yellowish-green, frothy discharge with a strong odor
• Vulvar itching, pain during urination, frequent urination

Antibiotic treatment is necessary, and even if a sexual partner has no symptoms, getting tested and treated together helps reduce reinfection. If you're curious about related tests, you can refer to STD Infection Tests.

If you find it difficult to self-diagnose based on symptoms alone, don't hesitate to get it checked.

How Vaginitis Treatment is Conducted at Blanc

The consultation proceeds smoothly step by step.

1. During registration and medical history taking, we confirm the onset of symptoms, frequency of recurrence, and whether self-treatment has been attempted. More specific details help in tracing the cause.
2. Vaginal discharge is collected with a swab, and a PCR test is requested from a contracted testing laboratory. Results are usually available within 2-3 days.
3. Based on the test results, appropriate medication is prescribed for bacterial, candidal, or trichomonal vaginitis. Since different pathogens require different medications, prescribing based on test results is crucial for reducing recurrence.
4. We also provide guidance on lifestyle habits tailored to your individual situation, such as vaginal cleansing methods, underwear materials, and combining probiotics with antibiotic use.

If you've postponed check-ups for a long time, you can also refer to our guide for Those Who Have Postponed Check-ups.

When It's Better to Get Checked at a Clinic

• If over-the-counter medications have been ineffective or symptoms quickly return
• If changes in odor and discharge persist for more than 2 weeks
• If itching is accompanied by pain during urination
• If discharge of a different color or characteristic than before appears

Even if an ultrasound shows no specific abnormalities, the symptoms themselves are important clues. It's best not to neglect symptoms simply because results appear normal.

Frequently Asked Questions

Q. Can I get vaginitis even if I haven't had sexual intercourse? Yes, it's possible. Bacterial vaginosis and candidal vaginitis can occur regardless of sexual experience.

Q. Can I try an over-the-counter medication once? You can try it once if candidal vaginitis is relatively clearly suspected, but if it recurs or the symptoms are different, testing is necessary. Repeated use without knowing the type can lead to resistance.

Q. Can I receive treatment during my period? It depends on the symptoms, so it's best to call and check before visiting.

Q. Is it okay for unmarried women? Of course. Anyone can visit regardless of their sexual experience.

If vaginitis is recurrent, organizing the onset of symptoms and the characteristics of discharge beforehand and starting the process of identifying the cause with a healthcare professional is the starting point for recovery.
