A ring pessary without support, also called an open ring pessary or pessary ring without support, is a soft, flexible silicone ring that holds up the uterus and vaginal walls to manage mild to moderate pelvic organ prolapse, without surgery. This open-ring design has no center membrane, so it folds easily to put in and take out. Available in sizes 0–9 (44–102 mm), FDA 510(k) cleared, no prescription needed. Recommended by OB-GYN clinics to their patients. Made in USA and ships from California. It costs from $49.99, is made in the USA, and needs no prescription; SciMed ships it same day from San Jose, California on orders placed before 2 PM PT (free US shipping on orders $99+), and sealed, unopened packs carry a 30-day size exchange with a free prepaid return label.
Pessaries should be fitted and used under the supervision of a qualified healthcare professional. This page is educational information about SciMed products, not medical advice. If you are unsure of your size or type, ask your clinician or start with a fitting pack.

One ring lasts 1–2 years — a few dollars a month, instead of a recurring spend on pads or repeat clinic fitting visits.
First time? The three worries everyone has:
“Will it hurt to insert?” The ring is soft silicone — fold it flat, use a little water-based lubricant, and insert it like a tampon. Most wearers manage it themselves after the first try or two. Step-by-step guide
“Is discharge or odor normal?” A mild increase in discharge is common and usually nothing to worry about. Persistent odor, discoloration or irritation means it is time to check in with your clinician. What's normal, what isn't
“What if it slips or falls out?” That almost always means the size is off — go one size up, or find your fit first with the Fitting Pack. Sealed size exchanges are free within 30 days.

Why Choose a Ring Pessary Without Support
As a silicone ring pessary for prolapse, the open-ring (without-support) configuration is the standard first-line ring pessary for patients without anterior compartment prolapse. The simple ring design folds easily for self-insertion and removal, is generally well tolerated for long-term daily wear, and can typically be worn during intercourse without removal, unlike the with-support membrane design.
- ✓ Helps keep your pessary clean between wears

Frequently Asked Questions
What is an open ring pessary?
An open ring pessary is a ring pessary without support. It is a plain, flexible silicone ring with no center membrane. It sits inside the vagina and holds up the uterus and vaginal walls.
Is a pessary ring without support right for my prolapse?
It is usually the first choice for mild to moderate uterine or vaginal vault prolapse when there is no bladder drop (cystocele) or stress incontinence. If you have those, the ring pessary with support may suit you better. Ask your doctor if you are not sure.
Do I need a prescription?
No. A pessary is an FDA Class II device. We recommend that initial sizing be performed by a qualified provider.
What's the difference between Without Support and With Support?
The without-support (open ring) is the standard first-line ring pessary for prolapse alone. The with-support version adds an integrated membrane for cystocele/SUI.
Can I wear the pessary during sex?
Yes, for most patients the open-ring can be worn during intercourse without removal.
How do I know which size to order?
If your doctor gave you a size, order that size. Otherwise see our ring pessary size guide. If unsure, order the 3-size right-size pack.
How big is a size 3 ring pessary without support?
Size 3 is 64 mm (2.5 in) across. Size 4 is 70 mm and size 5 is 76 mm. Every size from 0 to 9 is $49.99. Pick the size from the menu above.
Do I need a Storage Case?
Strongly recommended for daily-wear patients. Silicone pessaries need clean, dry storage between wears to help prevent bacterial buildup. Add to cart above for $9.99 (vs $19.99 standalone).
Why sizes 0–9?
Size 9 (102 mm) is essential for patients with a significantly enlarged vaginal vault, post-childbirth, post-hysterectomy, advanced prolapse.
Is the pessary FDA-cleared?
Yes. FDA 510(k) cleared as Class II under FDA Product Code HHW.
Is the pessary HSA/FSA eligible?
Yes. HCPCS code A4562. SciMed is not a Medicare-enrolled DME supplier, so purchases from SciMed are not reimbursed by traditional Medicare.
What if it doesn't fit?
Contact us within 30 days and we will exchange the sealed, unopened pack for the right size — we email you a prepaid return label, so the exchange ships back free. If you would rather have a refund, you can return the sealed, unopened pack within 30 days (return postage is paid by you). Opened pessaries cannot be returned, for hygiene reasons.
Can I put it in and take it out myself?
Yes. Ring pessaries are designed for self-management. Most patients learn how during their first fitting visit. See our pessary guide for help.
How do I clean my pessary?
Wash it with warm water and mild, unscented soap. Do not use alcohol, petroleum-based products or harsh disinfectants. Store it clean and dry.
How much is shipping and how fast?
US orders under $99 ship by USPS for a flat $4.99. Orders of $99 or more ship free by USPS. Orders ship from California.

How to insert a pessary — the short version
- Wash your hands and empty your bladder first.
- Fold the ring in half so it forms a narrow oval, and add a little water-based lubricant to the leading edge — never use silicone lubricant on a silicone pessary.
- Get comfortable: stand with one foot on a chair, squat, or lie on your back with knees bent.
- Insert the folded ring folded-end first, guiding it up and back. Let it open once inside, then push it gently up behind the pubic bone.
- Check the fit: stand up, walk around and cough. Fitted well, you should not feel it at all. To remove it: Hook one finger over the rim, fold the ring slightly and ease it out slowly.

Choosing your size
This ring comes in Sizes 0–9 (1.75 in to 4 in across). Most wearers fit Sizes 3–5, and Size 4 is the single most common fit. If a clinician has already fitted you, order the same size — size numbers follow the same diameter ladder across brands.
Not sure of your size? Start with the Fitting Pack — three consecutive sizes to try at home. Keep the one that fits and return the two sealed pouches for $80 back, with a free prepaid return label. And if you order a single size here and it isn't right, sealed packs exchange free within 30 days.
Quick answers
Does inserting or removing it hurt?
It shouldn't. The ring is soft, flexible silicone — fold it flat, use a little water-based lubricant, and insert it like a tampon. Most wearers manage it themselves after the first try or two. Removal is the reverse: hook one finger over the rim, fold the ring slightly, and ease it out slowly.
How often do I take it out or change it?
Many wearers remove and wash their ring daily or a few times a week; others follow a schedule set by their clinician. Changing one is just removing it, washing it, and reinserting it (or swapping in a fresh ring). A ring pessary is designed for everyday wear, including overnight, unless your clinician advises differently.
How long does one ring last?
One SciMed ring lasts 1–2 years with normal care. Replace it sooner if the silicone cracks, stiffens, discolours, or stops holding its shape — and factor replacement into your routine at the 1–2 year mark even if it still looks fine.
How do I clean it?
Wash with warm water and mild, unscented soap, rinse well, and let it air dry before reinserting or storing it. Don't use harsh chemicals, bleach or scented washes on the silicone.
What if I can feel it, or it slips?
If you can feel the ring, it usually isn't in far enough — push it gently up behind the pubic bone. If it keeps slipping, especially when you use the toilet or exercise, the size is almost always too small: go one size up. The Fitting Pack removes the guesswork, and sealed single sizes exchange free within 30 days.
