"My HPV Won’t Go Away." What Can I Actually Do?
Most HPV clears by itself within a year or two. For about one in ten people, it doesn’t — and if that’s you, you’ve probably been told to come back in 12 months and repeat the test.
That waiting is the hard part. Here’s what’s worth knowing.
The things that genuinely help
Stop smoking. This is the single best-evidenced thing you can do. Smoking roughly doubles the chance HPV sticks around, and quitting improves your odds of clearing it. Quitline is free, and works.
Get vaccinated if you haven’t been. It won’t clear an infection you already have, but it protects you against the types you haven’t met yet, and reduces the chance of problems returning after any treatment. Funded in New Zealand up to age 26.
Go to your follow-up appointment. Unglamorous, and by far the most important thing on this page.
What about AHCC?
AHCC is a supplement made from shiitake mushroom extract. There’s no drug that eliminates HPV, so researchers have looked at whether the immune system — which does all the actual work — can be given a nudge.
In a 2022 randomised trial of women over 30 with HPV that had persisted more than two years:
- About 6 in 10 taking AHCC (3 g daily for six months) tested negative afterwards, compared with about 1 in 10 on a placebo.
- Roughly 4 in 10 of everyone treated were still negative six months after stopping.
- Side effects were no more common than with the dummy pill.
But be sceptical. Only 41 people completed that trial. The supplement company supplied the product. No larger study has confirmed it yet, and no screening guideline in New Zealand or anywhere else recommends it. It’s promising, not proven.
It also isn’t cheap — at the dose studied (3 g per day), expect a few hundred dollars a month, and it isn’t funded.
When AHCC isn’t appropriate
- You have high-grade cell changes (CIN3), or cervical cancer — these need treatment, and delay is risky
- You’re pregnant or breastfeeding
- You have a suppressed immune system, or take immune-modifying medication
- You have a mushroom allergy
Check with your pharmacist if you take regular medications.
The bottom line
AHCC is a reasonable thing to discuss with your doctor if you’re in the group that was studied and you can afford it. It’s safe and well tolerated. Just go in knowing the evidence is early.
And whatever you decide, keep going to your screening appointments. That’s what prevents cervical cancer. Everything else is a maybe.
Most people with a persistent HPV result never develop anything serious. If you’d like to talk through what your result actually means for you, I’m happy to see you.
