What Are Suppositories Made Of? Cocoa Butter, Glycerin and PEG Bases Explained
A suppository is an active ingredient carried in a base, and there are four bases on the OTC shelf. Cocoa butter melts at about body temperature and is the labeled protectant in Preparation H. Hard fat, hydrogenated vegetable oil, is the base in Dulcolax, FeverAll and Monistat ovules. Glycerin with sodium stearate is the whole of a Fleet glycerin suppository, which dissolves rather than melts. Polyethylene glycol dissolves too and tolerates heat best. And boric acid is a powder in a gelatin capsule. The base decides how a suppository melts, stores, leaks and whether it can be cut.

Tea Tree vs Boric Acid Suppositories: Two Non-Drugs, Different Labels, Different Risks
Neither treats anything. Boric acid suppositories (pH-D 600 mg, 36 count, $26.97) are supplements labeled for vaginal odor and pH support that are poisonous if swallowed. Tea tree oil suppositories (NutraBlast, 12 count, $13.99) are botanical inserts labeled for cleansing and freshness that draw more irritation reports. This page opens with the boric acid box warnings, keeps both products inside their labels, and sends anyone with symptoms to a clinician first.

Suppository Applicators Guide: Disposable, Reusable, and Who Needs One
A suppository applicator is a plunger tube that places a vaginal suppository high in the vagina without a finger. Miconazole kits such as Monistat include disposable ones; boric acid and moisturizer inserts usually do not, which is why pH-D, NutraBlast and NewLife sell them separately at roughly 60 cents to $1.90 each. Rectal suppositories are inserted by finger, and the only rectal applicator on the shelf is the pre-filled Fleet Liquid Glycerin bottle. This guide covers what fits what, disposable versus reusable, how to clean one, and when a finger is fine.

pH-D vs Love Wellness: The Reference Boric Acid Against the Loudest One
Same printed 600 mg, same warnings, different boxes and very different prices. pH-D Feminine Health 36 count at $26.97 is about $0.75 per suppository; Love Wellness The Killer 14 count at $17.68 is about $1.26. Boric acid is not FDA-approved to treat any condition; both labels describe it for vaginal odor and pH support, and every box warning is stated before the verdict.

NutraBlast Review: Boric Life, Tea Tree, Bundles and the Price That Built the Brand
NutraBlast is the value brand that earned a real following on the boric acid shelf. This review covers Boric Life in 14, 30 and 60 count, the tea tree suppositories, the pH strip and applicator bundles, and the wash, with AZO and pH-D as benchmarks. Boric acid is not FDA-approved to treat any condition; the warnings come first. Prices verified via the Amazon Creators API on September 5, 2026.

Monistat vs Boric Acid: An FDA-Approved Drug and a Supplement Are Not a Choice
Monistat is miconazole, an OTC antifungal drug with a Drug Facts panel that treats vaginal yeast infections. Boric acid suppositories are supplements that are not FDA-approved to treat any condition and are labeled for vaginal odor and pH support. They are not two options for one problem. The page's answer is a diagnosis: a clinician tells you which shelf, if either, applies. Monistat 3-Day is $17.49; pH-D boric acid 36 count is $26.97; the Monistat-branded boric acid that causes the confusion is $15.97. Prices verified via the Amazon Creators API on September 5, 2026.

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.

Love Wellness The Killer Review: What the Label Says, What the Name Implies
The Killer is the most-marketed boric acid suppository on Amazon: 600 mg, 14 or 28 to a box, from the brand that also sells Flora Power probiotic suppositories and Good Girl oral probiotics. This review separates the label from the name. Boric acid is not FDA-approved to treat any condition; the warnings come first. Prices verified via the Amazon Creators API on September 5, 2026.

How to Use a Vaginal Suppository: Applicator, Finger, Timing and Leakage
Wash your hands, load the suppository into its applicator or hold it between clean fingers, lie on your back with knees bent, insert it as far as is comfortable angled slightly toward your lower back, release it, and lie down. Nearly every label directs bedtime use because the base will melt and some of it will leak; a panty liner is the standard answer. Below: both methods, the label directions for miconazole, boric acid and moisturizer inserts, and the boric acid warnings every box carries.

How to Store Suppositories: Room Temperature or Refrigerator, by Type
Store suppositories cool, dry and sealed. Most labels direct controlled room temperature, roughly 68 to 77 degrees Fahrenheit, and several add that the product may be refrigerated or should be chilled if it has softened. Cocoa butter and hard-fat suppositories are the ones that belong in the refrigerator in a warm house; glycerin suppositories keep at room temperature in a sealed jar or wrapper; boric acid and other capsules want a dry cabinet. The table below gives the storage line for each type, and the bathroom is the wrong room for all of them.

Do Suppositories Expire? What the Date Means and What Changes After It
Yes. Every OTC drug suppository carries an expiration date because FDA labeling rules require one, and the FDA's standing advice is not to use medicine past that date. Boric acid, probiotic and moisturizer inserts carry a best-by or expiration date set by the maker. Past the date, a fat-based suppository can go rancid or crumble, a glycerin suppository can dry and shrink, and any active ingredient may have lost strength. This page explains the date, what it covers, and how to buy the count you will actually use.

Boric Acid vs Probiotic Suppositories: Two Supplements, Two Different Jobs
Neither is a drug and neither treats anything. Boric acid suppositories (pH-D 600 mg, 36 count, $26.97) are labeled for vaginal odor and pH support and carry a poison warning. Probiotic suppositories (Love Wellness Flora Power, 10 count, $17.68) are dietary supplements labeled to support vaginal flora. This page keeps them apart, opens with the boric acid box warnings, and explains why owners describe using them in sequence rather than choosing one.

Best Feminine Washes with Boric Acid (2026): pH-D, Summer's Eve, NutraBlast and Monistat Maintain
