Intimate health concerns are among the most common reasons women visit a pharmacy, yet they’re also among the most embarrassing to discuss. This frank guide covers the most common conditions, how to distinguish between them, and when OTC treatment is appropriate.
The Healthy Vaginal Environment
The healthy vagina is not sterile — it’s dominated by Lactobacillus species that produce lactic acid, maintaining an acidic pH of approximately 3.8–4.5. This acidity inhibits the growth of pathogenic bacteria and yeast. Disrupting this balance — through antibiotics, hormonal changes, sexual activity, douching, or perfumed products — can allow opportunistic overgrowth of either Candida yeast (thrush) or anaerobic bacteria (bacterial vaginosis). Understanding which condition you have is essential, because they require completely different treatments.
Distinguishing Thrush from Bacterial Vaginosis
| Feature | Thrush (Candida) | Bacterial Vaginosis |
|---|---|---|
| Discharge | White, thick, “cottage cheese” | Grey-white, thin, watery |
| Odour | Mild or yeasty; not offensive | Fishy odour, worse after sex |
| Itch | Intense | Mild or absent |
| Soreness | Yes | Minimal |
| OTC treatment? | Yes | OTC options available |
If you’re unsure which you have — particularly if this is your first episode or if symptoms are unusual — see a GP or sexual health clinic for a swab test. Treating BV with antifungals (for thrush) and vice versa is ineffective and may worsen the condition.
Bacterial Vaginosis
BV is the most common cause of vaginal discharge in women of reproductive age. It is caused by an overgrowth of anaerobic bacteria (Gardnerella vaginalis and others) replacing the normal Lactobacillus flora, leading to a rise in vaginal pH. It is not sexually transmitted (though sexual activity can be a trigger). Standard treatment requires prescription antibiotics (metronidazole). However, OTC vaginal acidic gel (Balance Activ, Canesbalance) can treat mild BV and reduce recurrence by restoring vaginal pH — it’s a good first-line option for mild or recurrent cases. If no improvement in 3–5 days, prescription treatment is needed.
Vaginal Dryness and Atrophic Vaginitis
Vaginal dryness — most commonly during and after menopause due to oestrogen decline — causes discomfort, itching, painful sex, and increased UTI susceptibility. OTC options: non-hormonal vaginal moisturisers (Replens, YES VM) applied 3× weekly for baseline hydration. Vaginal lubricants (YES WB water-based, YES OB oil-based) for use during sexual activity. For persistent or severe symptoms, local vaginal oestrogen (Gina 10mcg estradiol vaginal tablet) became available without prescription in the UK in 2023 — a significant advance for post-menopausal women.
