Vaginal Infections: Causes, Symptoms & OTC Treatments

Vaginal infections are one of the most common women’s health concerns in the United States. Millions of women experience symptoms like vaginal itching, unusual discharge, burning sensation, or odor at least once in their lifetime. The good news? Many vaginal infections can be treated effectively with over-the-counter (OTC) treatments or prescription medications when needed.

In this comprehensive 2026 guide by Skymeds, we’ll explain the causes, symptoms, types, and best OTC treatments for vaginal infections — using medically updated information and beginner-friendly language.

What Are Vaginal Infections?

Vaginal infections occur when the natural balance of bacteria and yeast in the vagina is disrupted. The vagina normally maintains a healthy balance of good bacteria and a slightly acidic pH. When this balance changes, harmful bacteria or fungi can overgrow, leading to infection.

The three most common types include:

1. Yeast infection (Vaginal candidiasis)

2. Bacterial vaginosis (BV)

3. Trichomoniasis (a sexually transmitted infection)

Each type has different causes and treatments, which we’ll discuss below.

What Causes Vaginal Infections?

If you're wondering what causes vaginal infections? — several factors may contribute:

1. Hormonal Changes

Pregnancy, menopause, birth control pills, and menstrual cycles can alter vaginal pH levels.

2. Antibiotics

Antibiotics kill good bacteria, increasing the risk of yeast overgrowth.

3. Poor Intimate Hygiene

Overwashing, douching, and using scented products can disturb natural flora.

4. Tight Clothing

Non-breathable fabrics create a moist environment ideal for fungal growth.

5. Unprotected Sex

New sexual partners may introduce bacteria that alter vaginal balance.

Symptoms of Vaginal Infection

The symptoms of vaginal infection vary depending on the type. Common signs include:

• Vaginal itching and irritation

• Thick white discharge (cottage cheese-like in yeast infections)

• Gray or fishy-smelling discharge (common in BV)

• Burning sensation during urination

• Pain during intercourse

• Redness and swelling

If you notice vaginal itching and discharge, it's important to identify the type before starting vaginal infection treatment.

Types of Vaginal Infections & Treatments

1. Yeast Infection (Vaginal Candidiasis)

Yeast infections are caused by overgrowth of Candida fungus.

Symptoms:

• Thick white discharge

• Severe itching

• Redness

• Burning

Best OTC Treatment for Vaginal Yeast Infection

Most yeast infections respond well to:

• Vaginal antifungal cream (clotrimazole, miconazole)

• Antifungal suppositories

• Single-dose oral fluconazole (prescription)

If you’re searching for how to get rid of vaginal itching fast, antifungal creams typically start relieving symptoms within 24 hours.

At Skymeds, you can find trusted vaginal antifungal cream options for quick and effective yeast infection treatment.

2. Bacterial Vaginosis (BV)

BV occurs when harmful bacteria outnumber good bacteria in the vagina.

Symptoms:

• Thin gray discharge

• Fishy vaginal odor

• Mild irritation

Bacterial Vaginosis Treatment

Unlike yeast infections, BV often requires prescription antibiotics such as:

• Metronidazole

• Clindamycin

However, some women look for over the counter medicine for bacterial vaginosis. While limited OTC options exist, vaginal pH balancing gels and probiotics may support recovery.

For persistent symptoms, consult a healthcare provider.

3. Trichomoniasis

This is a sexually transmitted infection (STI).

Symptoms:

• Frothy greenish discharge

• Strong odor

• Itching

• Pain during urination

Treatment requires prescription antibiotics. OTC treatment for vaginal infections does not work for trichomoniasis.

How to Treat Vaginal Infections at Home

If symptoms are mild and clearly resemble a yeast infection, you may try:

• OTC antifungal creams

• Vaginal suppositories

• Probiotic supplements

• Avoiding scented hygiene products

Always complete the full treatment course.
