Most guidelines suggest a pessary should be removed and cleaned every three to six months if your provider manages it in the office, though a well-designed trial has shown that visits every 24 weeks work just as well as every 12 weeks for common pessary types. If you handle your own pessary at home, the cleaning schedule shifts to somewhere between nightly and monthly, depending on which type you use and your comfort level. The “right” interval is less fixed than many patients assume, and the evidence base has changed considerably in recent years.
What the Research Says About Office Visit Intervals
For decades the standard advice was to see your provider every three months for a pessary check, removal, and cleaning. That interval was based mostly on tradition and clinical habit, not hard evidence. A randomized noninferiority trial published in Obstetrics & Gynecology tested whether stretching office visits to every 24 weeks was just as safe as visits every 12 weeks. The study enrolled women using ring, Gellhorn, or incontinence dish pessaries for prolapse or incontinence and followed them for 48 weeks. Vaginal epithelial abnormalities, meaning breaks or erosions in the vaginal lining, occurred at similar rates in both groups. Visits every 24 weeks proved noninferior to the traditional every-12-week schedule.1Obstetrics & Gynecology. Timing of Office-Based Pessary Care
This finding is significant because more frequent office visits are not just inconvenient. They can be genuinely distressing. Research has noted that roughly 70 percent of older women feel uncomfortable handling a vaginal pessary, and for some, each office removal is a painful experience that makes them want to stop using the device entirely.2PubMed Central.

A prospective observational study – Section: Discussion Knowing that a six-month interval is safe for many women means fewer of those difficult appointments without added risk.
Continuous Wear Without Regular Removal
Some women never remove their pessary between office visits, and the evidence suggests this can be safe for extended periods under proper follow-up. A prospective observational study of women with advanced prolapse using ring pessaries without a support membrane found that continuous wear, with no periodic removal, cleaning, or replacement, was associated with a high success rate and mild side effects. In women who had not had a hysterectomy, continuous use was considered safe for up to four years. For those who had undergone hysterectomy, the safe window was closer to two years, after which the risk of the pessary becoming embedded in the vaginal tissue increased.3PubMed Central. How often should ring pessaries be removed or changed in women with advanced POP? A prospective observational study
This challenges the assumption that every pessary needs to come out on a rigid schedule. For women with advanced prolapse who cannot easily manage their own device and who find office visits stressful, a longer interval of continuous wear with periodic provider check-ups (rather than full removal and cleaning every time) may be a reasonable approach. The key distinction is that “leaving it in” is not the same as “forgetting about it.” These women were still being monitored by their providers.
What Builds Up on a Pessary Over Time
A pessary is a foreign body sitting in a warm, moist environment, so biological buildup is inevitable. An electron microscopy study of 40 ring pessaries confirmed that every single one had a bacterial biofilm on its surface. When researchers analyzed the microbial communities on the pessaries, about 40 percent were dominated by Lactobacillus, the beneficial bacteria that normally keep the vagina healthy. The remaining 60 percent were dominated by anaerobic and facultative organisms, which are associated with vaginal infections.4PubMed. Bacterial biofilm formation on vaginal ring pessaries used for pelvic organ prolapse
This biofilm matters because pessary use clearly shifts the vaginal environment. Women wearing pessaries are about four times more likely to develop bacterial vaginosis than women without one, according to a study that found BV in about a third of pessary users compared to 10 percent of controls.5PubMed. Bacterial vaginosis increases in pessary users They are also far more likely to be bothered by vaginal discharge: roughly 30 percent of pessary users reported bothersome discharge in one study, compared to just 2 percent of controls, and microscopic evidence of inflammation appeared within the first two weeks of use.6PubMed.

Does More Frequent Removal Actually Help the Vaginal Flora?
You might expect that removing and cleaning a pessary more often would keep the vaginal environment healthier. The answer is somewhat nuanced. A study comparing women who removed their pessary daily, weekly, or less often than weekly found that at two weeks, daily removers had a higher prevalence of Lactobacillus-dominant vaginal flora (41 percent) compared to weekly removers (24 percent) and those removing less often (9 percent). But by three months, that gap had disappeared: Lactobacillus prevalence was statistically similar across all groups.7PubMed Central. Changes in the Vaginal Microenvironment as Related to Frequency of Pessary Removal
There was, however, one persistent finding. Women who removed their pessary less than once a week were more likely to have anaerobic-dominant flora at three months: about 76 percent of infrequent removers had anaerobic predominance, compared to roughly 52 percent of more frequent removers. This difference held up even after adjusting for other factors.7PubMed Central. Changes in the Vaginal Microenvironment as Related to Frequency of Pessary Removal The practical takeaway: removing your pessary at least once a week may help limit the shift toward the kinds of bacteria that cause odor and discharge, even if daily removal does not seem to offer much extra benefit over weekly removal in the long run.
Self-Management at Home
An increasing body of evidence supports teaching women to remove, clean, and reinsert their own pessaries at home rather than relying entirely on clinic visits. A randomized trial (known as the TOPSY trial) compared self-management to clinic-based care and found that women in the self-management group reported a lower percentage of pessary-related complications over 18 months.8eClinicalMedicine. Clinical effectiveness of vaginal pessary self-management vs clinic-based care for pelvic organ prolapse (TOPSY) A separate retrospective study found that self-care users experienced fewer vaginal erosions and needed fewer office visits than those managed exclusively in the clinic.9Urogynecology. Self-care Pessary Management and Factors Associated With Long-Term Pessary Use
Women who self-manage also tend to stick with their pessary longer. One retrospective study found that among patients with a pessary type suitable for self-management, 97 percent in the self-management group continued treatment compared to 74 percent managed solely in the clinic.10International Urogynecology Journal. The Role of Self-Management in Pessary Therapy for Pelvic Organ Prolapse—A retrospective cohort study Self-management enables you to decide when to take the pessary out, for instance before intercourse, without scheduling an appointment. It also gives you direct control over how frequently the device gets cleaned.
The typical home cleaning routine is straightforward: remove the pessary, wash it with warm soapy water (no harsh disinfectants needed), and reinsert it. A clinical audit of monthly self-management with ring pessaries used exactly that protocol, advising patients to wash the ring in hot soapy water once a month.11European Journal of Obstetrics & Gynecology and Reproductive Biology: X. Does monthly self-management of vaginal ring pessaries reduce the rate of adverse events? A clinical audit Many providers now recommend that self-managing patients clean their pessary somewhere between once a week and once a month, depending on individual comfort and symptoms like discharge or odor.
Pessary Type Changes the Equation
Not all pessaries are created equal when it comes to removal and cleaning. Ring pessaries, the most commonly used type, are designed to be relatively easy to insert and remove, making them the best candidates for self-management. Most women can learn to fold a ring pessary and slide it in and out with practice, similar in concept to using a diaphragm.
Space-occupying pessaries such as the Gellhorn, cube, or donut are a different story. These devices are bulkier, sit more firmly in the vaginal canal, and are harder to remove on your own. They are typically reserved for more advanced prolapse where a ring pessary does not provide enough support, and most women using these types depend on their provider for removal and reinsertion. The complications of a neglected space-occupying pessary can be more severe because these devices exert greater pressure on the vaginal walls. A case report described a 91-year-old woman whose Gellhorn pessary eroded into her urinary bladder after she missed a scheduled six-month cleaning appointment due to a hospital admission.12PubMed Central. Open removal of a migrated Gellhorn pessary and repair of a vesicovaginal fistula
If you use a ring pessary and are comfortable handling it, weekly or even nightly removal for cleaning is entirely reasonable. If you use a Gellhorn or similar device and rely on office visits, your provider will likely schedule you every three to six months, with the newer evidence suggesting the longer end of that range is usually safe.
What Happens When a Pessary Is Truly Neglected
The complications from a pessary left in place far too long, sometimes for years, are the stuff of urogynecology case reports, and they are worth understanding so you can avoid them. An integrative review of the literature found that the most common complications related to pessary use overall are vaginal discharge, vaginitis, erosion, and bleeding, and these were closely linked to how long the pessary had been left in place.13PubMed Central. An integrative review and severity classification of complications related to pessary use in the treatment of female pelvic organ prolapse
At the severe end, neglected pessaries can cause impaction (where the device becomes embedded in the vaginal tissue), fistulas (abnormal tunnels forming between the vagina and the bladder or rectum), and even bowel evisceration through the vaginal vault.14PubMed. Neglected pessary causing a rectovaginal fistula: a case report A systematic review of rare pessary complications found that among 36 case reports, the most frequent serious outcomes were vesicovaginal fistula (about 25 percent of cases), rectovaginal fistula (about 19 percent), vaginal impaction (about 11 percent), and small bowel evisceration (about 8 percent).15BJUI Compass. Rare complications of pessary use: A systematic review of case reports
These outcomes are genuinely rare and are almost exclusively reported in women who went months or years without any follow-up. They should not alarm someone who is keeping up with regular checks. But they illustrate why “I’ll just leave it” without any monitoring plan is a risk, especially with space-occupying pessary types.
The Role of Vaginal Estrogen
Postmenopausal women, who make up the majority of pessary users, often have thinner, more fragile vaginal tissue due to declining estrogen levels. This makes them more susceptible to the erosions and ulcers that can develop where a pessary presses against the vaginal wall. Many providers prescribe vaginal estrogen cream alongside a pessary to protect the tissue, and the evidence is growing that this genuinely helps.
A large randomized, double-blind trial published in the BMJ found that intravaginal conjugated estrogen reduced several common pessary-related problems. Excessive discharge dropped from about 26 percent in the placebo group to 16 percent with estrogen. Vaginal erosion or ulcer fell from about 7 percent to 2 percent, and vaginal bleeding from roughly 6 percent to about 1 percent.16BMJ. Effects of intravaginal conjugated oestrogen on pessary continuation for pelvic organ prolapse An earlier observational study similarly noted that non-ring pessary users who did not use vaginal estrogen had a higher risk of ulceration, bleeding, and discharge.17PubMed. Does vaginal estrogen treatment with support pessaries in vaginal prolapse reduce complications?
The picture is not quite unanimous, though. A systematic review and meta-analysis of estrogen’s effect on vaginal complications from pessary use found a pooled odds ratio for vaginal ulceration that was close to 1.0, meaning no clear difference, although the included studies varied in quality and design.18PubMed. Effect of estrogen on vaginal complications of pessary use: a systematic review and meta-analysis The BMJ trial, being larger and more rigorous than most prior work, probably represents the best current evidence, and the direction of the findings is encouraging. If you are postmenopausal and using a pessary, asking your provider about vaginal estrogen is a reasonable step, particularly if you experience recurring erosions or discharge.
Removing a Pessary for Sex
Whether to remove a pessary before intercourse is a practical question that comes up often and influences how frequently the device gets handled. Among sexually active women using a pessary, about 70 percent removed it for sex “usually” or “always” at three months of use. The most common reasons were that their partner could feel the device during intercourse (about 31 percent) and that the pessary was uncomfortable during sex (about 20 percent). Over half of the women who removed their pessary for sex said their partner preferred them to do so.19PubMed Central. Sexual Function and Pessary Management Among Women Using a Pessary for Pelvic Floor Disorders
If you are removing your pessary before sex and reinserting it afterward, you are effectively handling and cleaning it on an as-needed basis. This incidental handling serves as a form of routine maintenance. Women who are sexually active and already comfortable removing their pessary may naturally end up on a more frequent cleaning schedule than those who leave it in continuously, which could partly explain why self-management is associated with fewer complications in the research.
When Frequent Removal Is Not Practical
For some women, particularly those who are elderly, have limited mobility, or have cognitive decline, handling a pessary at home is not realistic. Frequent removal can be anxiety-provoking, and the research confirms this: about half of patients cannot manage the pessary themselves or with a caregiver’s help. The discomfort and pain of repeated office removals can actually drive women to abandon pessary use altogether.2PubMed Central. How often should ring pessaries be removed or changed in women with advanced POP? A prospective observational study – Section: Discussion
For these patients, the evidence on extended intervals is reassuring. A visit every six months for a ring pessary, combined with provider monitoring for symptoms in between, is supported by current evidence. If the woman has no symptoms of erosion, unusual bleeding, or worsening discharge, stretching the interval is likely safe. The goal is to find a schedule that keeps the pessary effective without making the maintenance so burdensome that the patient gives up on a treatment that was working well for her prolapse or incontinence symptoms.
Caregivers and family members sometimes worry about a loved one “forgetting” about a pessary. If the patient is being seen by a provider regularly, the risk of a truly neglected pessary is low. The dangerous scenarios in the literature involve women who fall entirely out of the healthcare system for extended periods. As long as someone is tracking the next appointment, the pessary is being managed even if it is not being removed at home between visits.
A Practical Framework for Cleaning Schedules
Because the evidence now spans everything from nightly removal to years of continuous wear, here is how the pieces fit together based on your situation:
- Ring pessary, self-managing: Remove and wash with warm soapy water anywhere from nightly to once a month, depending on comfort and symptoms. Weekly is a reasonable middle ground that appears to limit unfavorable shifts in vaginal bacteria.
- Ring pessary, office-managed: Office visits every 12 to 24 weeks for removal, cleaning, and vaginal inspection. The longer interval is supported for women without symptoms.
- Space-occupying pessary (Gellhorn, cube, donut): Typically office-managed, with visits every 3 to 6 months. These devices exert more pressure on vaginal walls and carry a higher risk of erosion with prolonged unmonitored use.
- Any pessary in a frail or immobile patient: The least-frequent safe schedule that keeps the patient in care. For ring pessaries, continuous wear with visits every 6 months is supported if the provider monitors for complications. Avoiding unnecessarily frequent and distressing removals helps the patient stay on treatment.
Regardless of your schedule, a few symptoms should prompt an unscheduled visit: new bleeding, foul-smelling discharge, pain that was not there before, or difficulty urinating or having a bowel movement. These can signal erosion, infection, or pessary migration and are worth checking out sooner rather than waiting for your next routine appointment.
