Peridex is the brand name for chlorhexidine gluconate 0.12% oral rinse—a prescription-strength antiseptic mouthwash first approved by the FDA in August 1986. It is used to treat gingivitis, a condition marked by redness, swelling, and bleeding of the gums. Generic versions are widely available under names like chlorhexidine gluconate oral rinse, and other brands include PerioGard and Paroex.
Peridex is used as part of a comprehensive gingivitis treatment plan alongside professional dental cleanings, daily brushing, and flossing. Dentists and periodontists prescribe it for a defined period, typically 2 to 6 months. The standard dose is 15 mL (one capful) swished for 30 seconds, twice daily, after brushing.
Chlorhexidine gluconate is also used off-label for post-surgical oral care following extractions, implant placement, and periodontal surgery, as well as for oral mucositis prevention in chemotherapy patients.

Peridex works through the antimicrobial properties of chlorhexidine gluconate, a cationic bisbiguanide compound. The drug carries a positive electrical charge that attracts it to the negatively charged surfaces in your mouth—including bacterial cell walls, tooth enamel, and gum tissue.
Approximately 30% of the drug is retained in the oral cavity after rinsing and is slowly released over 8–12 hours. At low concentrations, chlorhexidine disrupts bacterial cell membranes (bacteriostatic effect). At higher concentrations, it causes precipitation of the bacterial cytoplasm, killing the bacteria outright (bactericidal effect). This residual activity is what makes Peridex significantly more effective than OTC mouthwashes.
Clinical studies have shown that 6 months of consistent twice-daily use reduces bacterial counts in plaque by 54–97% across aerobic and anaerobic species. The drug is active against a broad spectrum of oral pathogens, as well as some fungi and viruses. It does not cause significant bacterial resistance when used at therapeutic concentrations.
0.12% — oral rinse
15 mL (one capful) swished for 30 seconds, twice daily after brushing. Do not swallow. Available in 473 mL (16 oz) standard size; also available in 15 mL and 118 mL sizes.
Peridex and generic chlorhexidine gluconate 0.12% oral rinse are generally widely available in 2026. The medication is not listed on the FDA Drug Shortages database and is manufactured by multiple generic companies, providing a resilient supply chain. Most major pharmacy chains (CVS, Walgreens, Walmart, Costco) carry it routinely.
Some patients encounter friction when they ask for Peridex by brand name when only the generic is stocked, or when their insurance processes the claim incorrectly. Rural and small independent pharmacies may need to order it with 24–48 hours lead time. These are local and solvable issues, not a national shortage.
If you're having trouble locating it at your regular pharmacy, medfinder calls pharmacies near you to find which ones have it in stock and texts you the results, saving you the hassle of calling around yourself.
Peridex is not a controlled substance and has no DEA schedule, so any licensed healthcare provider with prescribing authority can write a prescription. In practice, it is almost exclusively prescribed by dental professionals after a gum evaluation. No DEA number is required—a dental license and NPI number are sufficient.
General dentists (DDS/DMD) — Most common prescribers; typically prescribe after cleaning and gum evaluation
Periodontists — Dental specialists for gum disease; frequently prescribe as part of periodontal therapy
Oral and maxillofacial surgeons — Often prescribe for post-surgical care after extractions, implants, and jaw surgery
Nurse practitioners and physician assistants with prescribing authority — Can prescribe; uncommon outside dental-adjacent context
Primary care physicians (MDs/DOs) — Can legally prescribe; rarely do so outside of a dental referral context
Telehealth dental services can also prescribe Peridex in many cases, particularly for patients who have already been diagnosed with gingivitis and need a refill. However, an in-person dental visit and professional cleaning are recommended for the initial diagnosis and treatment, since chlorhexidine alone does not remove existing plaque and tartar.
No. Peridex (chlorhexidine gluconate 0.12% oral rinse) is not a controlled substance and has no DEA scheduling. It is a prescription-only medication, but it carries no abuse potential and no special prescribing restrictions. Your dentist does not need a DEA number to prescribe it—a dental license and NPI number are sufficient.
Because it is not scheduled, Peridex can be prescribed via teledentistry platforms, refilled without special restrictions, and transferred between pharmacies without the limitations that apply to controlled substances. Prescriptions can also be called in or sent electronically without the written-prescription requirements that apply to Schedule II drugs.
Tooth and surface staining — Brown or yellowish discoloration; visible as early as 1 week; removable by dentist at cleaning
Increased tartar/calculus — Supragingival calculus formation increases; addressed at 6-month dental cleanings
Altered taste perception — Bitter aftertaste and altered food flavors for up to 4 hours after rinsing; typically improves with continued use
Oral mucosal irritation or minor superficial peeling (less common)
Dry mouth sensation (less common)
Severe allergic reaction / anaphylaxis (rare) — Hives, difficulty breathing, swelling of face/lips/tongue/throat, cold sweats, dizziness; requires immediate emergency care

Permanent taste alteration (very rare) — Reported in post-marketing surveillance; discuss with your dentist

BCG Vaccine Live
majorContraindicated: chlorhexidine antimicrobial activity may reduce vaccine efficacy. Wait until antimicrobial therapy is complete before administering live bacterial vaccine.
Typhoid Vaccine Live (oral)
majorContraindicated: chlorhexidine may inactivate the live bacterial component of the oral typhoid vaccine. Wait until antimicrobial therapy is complete.
Gintuit (allogeneic cultured keratinocytes/fibroblasts)
majorTopical antiseptics degrade Gintuit cellular therapy. Irrigate area with saline and allow wash-out period before applying Gintuit.
Digoxin
minorMinor: chlorhexidine may increase digoxin levels by altering intestinal flora if swallowed. Use with caution and monitor in patients on digoxin.
Oral Contraceptives / Estrogen
minorMinor: if swallowed, chlorhexidine may theoretically reduce estrogen absorption via intestinal flora changes. Risk of contraceptive failure is low but exists.
Peridex (chlorhexidine gluconate 0.12% oral rinse) is a well-established, effective, and affordable treatment for gingivitis. It has been in clinical use since 1986 and has an extensive body of evidence supporting its efficacy. With a retail price of $15–$40 (and as low as $9–$11 with a GoodRx coupon), it remains one of the most cost-effective prescription medications in dentistry.
Availability is generally not an issue—the medication is manufactured by multiple companies and stocked at most major pharmacy chains. Patients who encounter difficulty at one pharmacy should ask for the generic by name (chlorhexidine gluconate 0.12%), try another pharmacy, or use a GoodRx coupon. The most common barriers to access are brand confusion, insurance processing hiccups, and local stock gaps—all of which are solvable.
If you are having trouble finding Peridex at a pharmacy near you, medfinder can call pharmacies in your area to identify which ones have it in stock and text you the results—saving you the time and hassle of calling around yourself.
