The pill and yeast infections: what nobody mentioned when you got the prescription

I was prescribed the pill young, like almost everyone I knew. Nobody mentioned yeast infections. A few months later, I had my first one. Then another. I eventually worked out the connection and stopped taking it — but by then my body had been thrown off balance, and it took years to get back.

That’s my story. It isn’t everyone’s. But it’s common enough that you deserve to know it’s possible.

What the leaflet actually says

Look up the patient leaflet for some combined pills on FASS, and vaginal yeast infection is listed as a common side effect — meaning it affects somewhere between 1 in 100 and 1 in 10 users. It’s right there in the small print. It’s just rarely said out loud.

The research as a whole is more mixed. Oestrogen seems to make the vaginal environment friendlier to candida for some women, but not all. Sensitivity is individual.

The other side of the story

Here’s where it gets more interesting than “the pill is bad.” Hormonal contraception has consistently been linked with a lower risk of BV in large reviews of the research. So the same method might make one woman’s yeast worse and protect another woman against BV.

Which is exactly why the answer is never a blanket rule. It’s paying attention to your body.

If you suspect a connection

• Look at the timing. Did the infections start or change when you started, switched or stopped a method? Write it down.
• Don’t just stop. Stopping contraception without a plan is how people end up with a very different problem. Talk it through first.
• Ask about alternatives. In Sweden, a midwife (barnmorska) can help you compare options — hormonal ones with different hormone profiles, or non-hormonal ones like the copper IUD, condoms or a diaphragm, each with their own trade-offs.

You’re allowed to ask whether your contraception could be part of the picture. For a lot of us, it was.
