Check price on Amazon →Maintain by Monistat Review: The Boric Acid Line, Kept Apart From the Antifungal
Maintain is Monistat's boric acid supplement, not the miconazole drug the brand is known for. This review covers the 30 count suppositories and the odor control kit, states every boric acid warning first, puts Monistat 3-Day on the page only to show the difference, and benchmarks against AZO and pH-D. Boric acid is not FDA-approved to treat any condition. Prices verified via the Amazon Creators API on September 5, 2026.

Two things before anything else. First, the box: Maintain by Monistat Boric Acid Vaginal Suppositories are for vaginal use only. Never take one by mouth; boric acid is poisonous if swallowed. Keep them out of reach of children. Do not use if pregnant or nursing. Do not use on broken or irritated skin. They are not FDA-approved to treat any condition, and they do not treat, cure or prevent bacterial vaginosis or yeast infections; the label describes them for vaginal odor. See a clinician for a diagnosis before self-treating, and stop and see a clinician if symptoms persist. Second, the name: Maintain is not Monistat 1, 3 or 7. Those are miconazole, an FDA-approved OTC antifungal drug with a Drug Facts panel. Maintain is a boric acid supplement. Same logo, different shelf, different rules.
The verdict: Maintain by Monistat Boric Acid Vaginal Suppositories, 30 count at $15.97 (verified via the Amazon Creators API on September 5, 2026) is the cheapest boric acid suppository among the major brands, about $0.53 each ($15.97 divided by 30), with the widest retail distribution on the shelf. Its weakness is disclosure: the listing title states the count and not the milligrams, so this site prints no strength for it, while AZO and pH-D print 600 mg. Buy Maintain for the price and the brand; buy AZO if you want the strength on the box you are buying.
This review covers the Maintain suppositories, the Maintain odor control kit, and, for contrast only, Monistat 3-Day, so that nobody who lands here buys the wrong Monistat.

The short version
- Read the box first: vaginal use only, never by mouth (poison if swallowed), keep from children, not in pregnancy or nursing, not on broken skin, see a clinician for diagnosis and if symptoms persist. Not FDA-approved to treat any condition.
- Maintain is a boric acid supplement labeled for vaginal odor. Monistat 1, 3 and 7 are miconazole, an OTC drug labeled to treat vaginal yeast infections. The shared brand name is the whole confusion.
- Maintain 30 count at $15.97 is about $0.53 per suppository, the lowest per-piece price of the major brands on September 5, 2026. The odor control kit (wipes plus suppositories) is $12.29; its title states no counts.
- The Maintain listing title does not state the milligrams. AZO (600 mg, $19.49, about $0.65 each) and pH-D (600 mg, $26.97, about $0.75 each) do.
- If you have itching with thick discharge and a doctor has diagnosed a yeast infection before, the antifungal shelf is the one with an approved use; first-time or recurring infections are the label's ask-a-doctor line.

The Maintain line, the antifungal it is confused with, and two boric acid benchmarks. Strength and count come from the Amazon listing title or, for the drug, the Drug Facts label; where a title does not state a figure we say so. Cost per piece computed only where the count is stated.

Maintain by Monistat Boric Acid Vaginal Suppositories for Women, 30 Count
Monistat
Monistat's boric acid supplement, 30 for $15.97, about $0.53 each; milligrams not in the title.
Our verdict: Maintain is the cheapest way to buy a boric acid suppository from a name you know: $15.97 divided by 30 is about $0.53 each, under AZO and pH-D. It is a supplement for vaginal odor, not the miconazole drug that shares its logo, and it carries every boric acid warning. The listing title does not state the milligrams, so we print no strength; that is the one place the pricier brands beat it.
Verified: Boric acid vaginal suppositories, 30 count, from the Maintain by Monistat line, labeled for vaginal odor; milligram strength is not published in the listing title. Live at $15.97 on Amazon, verified via the Creators API on September 5, 2026.
The warnings, first. Maintain by Monistat Boric Acid Suppositories are for vaginal use only. Never take them by mouth; boric acid is poisonous if swallowed. Keep out of reach of children. Do not use if pregnant or nursing. Do not use on broken or irritated skin. Not FDA-approved to treat any condition. See a clinician for diagnosis, and stop and see a clinician if symptoms persist.
What the listing tells you: the brand, the line, the count (30) and the use (odor). What it does not tell you: the milligrams. Nearly every competitor states 600 mg, and Maintain may well be the same, but we print only what the listing prints. What owners consistently report: overnight dissolve, watery discharge the next morning (insert at bedtime, wear a liner), packaging on par with AZO, and the usual minority of irritation reports, for which the label's instruction is to stop and see a clinician. Mechanics are in how to use a vaginal suppository; the ranking that places it fourth overall is the best boric acid suppositories.
Who should buy it
Buy Maintain if you want a major-brand boric acid suppository at the lowest per-piece price among the names you know, you understand it is a supplement and not the Monistat antifungal, and you have read every warning.
What we don't like
The listing title does not state the milligrams, and the shared brand name invites exactly the drug-versus-supplement confusion this site exists to clear up.

Maintain by Monistat Boric Acid Odor Control Kit, Wipes and Suppositories
Monistat
Boric acid wipes and suppositories in one $12.29 kit; the title states no counts.
Our verdict: The kit is the entry point Monistat sells for the Maintain line: external wipes and internal suppositories in one box at $12.29. The title states no counts and no milligrams, so we compute no per-piece cost and print no strength. The suppositories carry every boric acid warning; the wipes are an external cosmetic and must not be confused with the suppositories or used internally.
Verified: Maintain by Monistat odor control kit pairing boric acid wipes with boric acid suppositories; the listing title states neither count nor milligrams. Live at $12.29 on Amazon, verified via the Creators API on September 5, 2026.
Half of this kit is boric acid suppositories. The Maintain Odor Control Kit includes suppositories that are vaginal use only, never by mouth (poisonous if swallowed), kept from children, not for pregnancy or nursing, not for broken skin, and not FDA-approved to treat any condition. The wipes are for external use.
Who should buy it
Buy the kit if you want to try the Maintain line with wipes included and you are not comparing on cost per suppository.
What we don't like
No counts and no milligrams in the title, so the value cannot be checked from the listing.

- Strength
- Not published in the listing title

Monistat 3-Day Yeast Infection Treatment, Miconazole Vaginal Suppositories
Monistat
Miconazole nitrate, an OTC drug labeled to treat vaginal yeast infections; not a supplement.
Our verdict: This card exists so nobody confuses it with Maintain. Monistat 3-Day is miconazole nitrate, an FDA-approved OTC antifungal with a Drug Facts panel: uses, treats vaginal yeast infections; directions, one suppository at bedtime for three days, ages 12 and up. The label sends first-timers and anyone with recurring infections to a doctor. It is a drug for a diagnosed condition, not an odor product, and it does nothing for what boric acid is labeled for.
Verified: Miconazole nitrate vaginal suppositories, 3-day course, an OTC drug whose Drug Facts panel states it treats vaginal yeast infections. Live at $14.12 on Amazon, verified via the Creators API on September 5, 2026.
Quoted from the Drug Facts, nothing added. Monistat 3-Day Suppositories contain miconazole nitrate. Uses, per the label: treats vaginal yeast infections and relieves the external itching and irritation that go with them. Directions, per the label: adults and children 12 years and older, insert one suppository into the vagina at bedtime for three days in a row; under 12, ask a doctor.
The rest of the drug line: Monistat 1-Dose (one ovule plus external cream, $18.44) and Monistat 7-Day cream ($16.18), compared in Monistat 1 vs 3 vs 7. The whole antifungal shelf is in the best yeast infection treatments.
Who should buy it
Buy Monistat 3-Day, not Maintain, if a doctor has diagnosed a vaginal yeast infection before, you recognize the symptoms, you are 12 or older, and you are not in one of the label's ask-a-doctor groups.
What we don't like
It is the right product for one diagnosed condition and useless for the others that share its symptoms; burning or itching on insertion is a labeled possibility; and it is not for first-time or recurring infections without a doctor.
- Active ingredient
- Miconazole nitrate (OTC drug)
- Strength
- 200 mg per suppository per the Drug Facts label (3-day course)
- Count
- 3 suppositories
- Form
- Vaginal suppository
- Label ages
- 12 years and older; under 12 ask a doctor
- Cost per dose
- About $4.71 ($14.12 divided by 3)
- Packaging
- 3-day treatment box
What we like
- FDA-approved OTC drug with a printed Drug Facts panel
- Labeled to treat vaginal yeast infections
Worth noting
- Not for first-time or recurring infections without a doctor
- Does nothing for non-yeast causes of the same symptoms
AZO Vaginal Boric Acid Suppositories for Women, 600 mg, 30 Count
AZO
The pharmacy brand's printed 600 mg, 30 for $19.49, about $0.65 each.
Our verdict: AZO is the closest like-for-like to Maintain: same count, same kind of brand, about twelve cents more per suppository ($19.49 divided by 30 is about $0.65), and a title that prints 600 mg. If the missing milligrams on the Maintain listing bother you, this is the fix. Same warnings, same odor-and-pH label.
Verified: 600 mg boric acid per suppository, 30 count, AZO. Live at $19.49 on Amazon, verified via the Creators API on September 5, 2026.
Identical warnings. AZO Boric Acid Suppositories are vaginal use only, never by mouth (poisonous if swallowed), kept from children, not for pregnancy or nursing, not for broken skin, and not FDA-approved to treat any condition.
Who should buy it
Buy AZO instead of Maintain if you want a printed 600 mg and a pharmacy brand, and twelve cents per piece is acceptable.
What we don't like
Slightly more per piece than Maintain and slightly more variable firmness reports than pH-D.
- Active ingredient
- Boric acid (supplement; not FDA-approved to treat any condition)
- Strength
- 600 mg per suppository
- Count
- 30
- Form
- Vaginal suppository (gelatin capsule)
- Label ages
- Adults; keep out of reach of children; not for pregnancy or nursing
- Cost per suppository
- About $0.65 ($19.49 divided by 30)
- Packaging
- 30 count box
What we like
- Printed 600 mg
- About $0.65 each
Worth noting
- More per piece than Maintain
pH-D Feminine Health Boric Acid Suppositories, 600 mg, 36 Count
pH-D Feminine Health
The reference boric acid suppository, 36 for $26.97, about $0.75 each.
Our verdict: pH-D is the shelf's reference product: printed 600 mg, printed 36 count, about $0.75 each ($26.97 divided by 36), the most consistent owner history and the fewest soft-capsule reports. It costs about twenty-two cents more per piece than Maintain. Same warnings, same odor-and-pH label.
Verified: 600 mg boric acid per suppository, 36 count, labeled for vaginal odor and pH balance support. Live at $26.97 on Amazon, verified via the Creators API on September 5, 2026.
Identical warnings. pH-D Boric Acid Suppositories are vaginal use only, never by mouth (poisonous if swallowed), kept from children, not for pregnancy or nursing, not for broken skin, and not FDA-approved to treat any condition.
Who should buy it
Buy pH-D instead of Maintain if you want everything printed and the most consistent owner reports, and the premium per piece is acceptable.
What we don't like
About $0.75 each, the most of the three boric acid products on this page.
- Active ingredient
- Boric acid (supplement; not FDA-approved to treat any condition)
- Strength
- 600 mg per suppository
- Count
- 36
- Form
- Vaginal suppository (gelatin capsule)
- Label ages
- Adults; keep out of reach of children; not for pregnancy or nursing
- Cost per suppository
- About $0.75 ($26.97 divided by 36)
- Packaging
- 36 count box
What we like
- Printed 600 mg and 36 count
- Most consistent owner history
Worth noting
- Most per piece of the three
What you'll need
The six things that go with a vaginal suppository: applicators, pH strips so you know what you are treating, a probiotic and a vitamin E option, a moisturizer, and a gentle wash. See a clinician for diagnosis. Prices are approximate at time of writing.

How we chose
Every product on this page went through the same checks. We confirmed each live Amazon listing and price through the Creators API on September 5, 2026, took strength and count from the listing title (or, for the miconazole drug, from its Drug Facts label), and wrote "not published" wherever a title states neither. We read the Maintain label for its use statement and warnings and the Monistat 3-Day Drug Facts panel for its uses, directions and ask-a-doctor lines, and we weighed owner reports for firmness on arrival, leakage, irritation, discharge and packaging. We do not use these products on ourselves and we claim no clinical outcomes. No brand paid for this review.
Compliance for this shelf. Maintain by Monistat is a boric acid supplement, not FDA-approved to treat any condition; we describe it as its label does, for vaginal odor, and we never say it treats, cures or prevents bacterial vaginosis, yeast infections or anything else. Every boric acid box warns: vaginal use only, never by mouth, poisonous if swallowed, keep away from children, do not use if pregnant or nursing, do not use on broken skin, see a clinician for diagnosis and if symptoms persist. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. Monistat 3-Day is an OTC drug: we quote its Drug Facts uses and directions only, and if this is your first vaginal yeast infection, or infections keep coming back, the label says to ask a doctor, and so do we.
Questions, answered
Is Maintain by Monistat the same as Monistat?
No. Maintain is Monistat's boric acid supplement line, labeled for vaginal odor and not FDA-approved to treat any condition. Monistat 1, 3 and 7 are miconazole nitrate, an FDA-approved OTC antifungal drug with a Drug Facts panel that states it treats vaginal yeast infections. They share a brand and nothing else.
Does Maintain treat yeast infections or BV?
No. Maintain is a boric acid suppository, and boric acid is not FDA-approved to treat any condition. The label describes it for vaginal odor. It does not treat, cure or prevent bacterial vaginosis or yeast infections. If you have symptoms, see a clinician for a diagnosis. These statements have not been evaluated by the Food and Drug Administration.
How many milligrams of boric acid are in Maintain?
The listing title does not state the milligrams; it states the count (30) and the use (odor). We print only what the listing prints. AZO and pH-D both state 600 mg in their titles if a printed strength matters to you.
What does Maintain cost per suppository?
About $0.53, from $15.97 divided by 30, verified via the Amazon Creators API on September 5, 2026. That is the lowest per-piece price among the major brands: AZO is about $0.65 and pH-D's 36 count about $0.75. The odor control kit is $12.29 but states no counts, so we compute nothing for it.
Can I use Maintain while pregnant or breastfeeding?
No. The boric acid label says do not use if you are pregnant or nursing, and this site repeats that without exception. See your clinician.
Can Maintain be taken by mouth?
Never. It is for vaginal use only, and boric acid is poisonous if swallowed. Keep it out of reach of children and away from oral supplements. If one is swallowed, contact Poison Control immediately.
I have itching and thick discharge. Do I want Maintain or Monistat 3-Day?
Neither product page can answer that; a clinician can. The Monistat 3-Day Drug Facts label says to ask a doctor if this is your first vaginal yeast infection or you have never had one diagnosed, if infections come back often, or if you have fever, chills, pain or a foul-smelling discharge. Maintain is a boric acid supplement labeled for odor and is not approved to treat anything. Get the diagnosis first.
Can I use Maintain and Monistat 3-Day at the same time?
Nothing on either label directs combined use, and this site does not invent regimens. Follow each label as written, and ask a clinician or pharmacist about any combination.
