How do you treat thrush after taking antibiotics

Vaginal thrush is an infection caused by an overgrowth of the yeast called Candida albicans. The yeasts are naturally occurring in the body but only in small amounts. Thrush can be really itchy, often causing irritation and vaginal discharge.

How can women get vaginal thrush from antibiotics?

Normally, there is a balanced mix of bacteria and yeast in the vagina. The former should dominate the latter in number.

Unfortunately, yeast infection on the mouth and vagina is common for women who recently took broad-spectrum antibiotics. This happens because the drugs kill both bad and healthy bacteria.

As a result, the number of healthy bacteria in the vagina decreases. Then, yeasts like Candida albicans grow uncontrollably and causes infection.

What are other causes of a vaginal yeast infection? 

  • High alcohol intake

  • Weak immune system

  • Use of oral contraceptives

  • Uncontrolled diabetes

  • Vaginal acidity

  • Pregnancy


Diagnosis of Vaginal Thrush

Symptoms of vaginal thrush include the following:

  • Redness and swelling

  • Itching

  • Painful intercourse

  • Creamy white lesions in the vagina

  • White discharge that is thick and cottage-cheese like in appearance

  • Burning sensation while urinating

It is easy to mistake the symptoms of vaginal thrush as that of bacterial vaginosis. Others may think of it as signs of STI. However, these are completely different medical conditions.

Thrush can affect women's health if not treated properly. This is why it is important to get a diagnosis by a doctor.

Treatment of Vaginal Thrush

There are several treatment options for yeast infection. Mild cases last for a few days. In addition, conditions may improve even without treatment. On the other hand, moderate and severe infections can last up to two weeks and require treatment.

OTC medication. Mild infections can be treated by antifungal creams that need to be directly applied to the vagina. In addition, you may use vaginal pessaries containing clotrimazole as an active ingredient.

Prescription medication. The doctor may prescribe strong antifungal agents for more serious cases of thrush. Common prescriptions include fluconazole, nystatin, and itraconazole.

Probiotics. Lactobacillus, the most common probiotic, naturally live in the vagina. In fact, it helps prevent the overgrowth of yeasts. Combining probiotics with medicines may make the treatment more effective.


You can take the following steps to prevent the onset or recurrence of vaginal yeast infection.

  • Avoid tight-fitting clothes. Instead, wear loose clothing and breathable underwear.

  • Practice proper hygiene. Always keep the vagina clean.

  • Avoid scented feminine wash, pads, and tampons.

  • Do not take long, hot baths. This is because yeasts prefer a warm and moist environment.

  • Make sure to stay dry. Change your clothes right after swimming.

  • Only use antibiotics when prescribed by your doctor.

  • If you have diabetes, manage your blood sugar level.

  • Do not use contraceptives with high levels of estrogen.


Do not self medicate if you have never been diagnosed with vaginal thrush before. Women who previously had yeast infection could use the same treatment plan recommended by the doctor. However, it is always best to avoid self-medication.
