What to Have Ready Before Contacting Listerine
For a product complaint, keep:
- Exact LISTERINE product name
- Flavor or variety
- Bottle or package size
- UPC or barcode
- Lot, batch or production code printed on the package
- Expiration date when one is shown
- Purchase date
- Retailer
- Receipt when available
- Photographs of leaking, damaged or unusual packaging
- Description of the problem
- Previous Consumer Care reference information
Do not publish medical information, home addresses, telephone numbers, email addresses, receipts or private customer-service correspondence in a public review.
Reporting a Listerine Product Problem
Contact LISTERINE if a product appears:
- Leaking
- Improperly sealed
- Discolored unexpectedly
- Different in taste or smell
- Damaged during normal use
- Missing product from the bottle
- Incorrectly labeled or packaged
Keep the bottle and cap until Consumer Care responds.
Product codes can help the manufacturer identify when and where a particular bottle was produced.
If the product was purchased from a grocery store, pharmacy, warehouse club or online retailer, that seller may handle the purchase refund while LISTERINE investigates the product-quality concern.
Reporting a Side Effect or Adverse Event
LISTERINE specifically publishes its Consumer Care number for reports of adverse events or side effects:
Current telephone hours are Monday through Friday from 9 a.m. to 5:30 p.m. Eastern time.
When reporting a reaction, be prepared to identify:
- The exact product
- How it was used
- When the reaction occurred
- The symptoms experienced
- Product and package information
What If Listerine Is Accidentally Swallowed?
LISTERINE product warnings generally state that the rinse should not be swallowed.
Current product labels also instruct consumers to get medical help or contact a Poison Control Center immediately if more than the normal amount used for rinsing is accidentally swallowed.
Follow the warning printed on the exact bottle because formulations and age directions differ.
Do not induce vomiting or take another action solely based on advice from an unofficial website.
How to Use Listerine Antiseptic Mouthwash
For current LISTERINE Original Intense Antiseptic Mouthwash, the published directions are:
- Use 20 mL, or approximately 4 teaspoonfuls.
- Use the mouthwash full strength.
- Rinse for 30 seconds.
- Use morning and night.
- Spit the rinse out.
- Do not swallow.
The current Original Antiseptic label says not to use that formulation in children younger than 12.
These directions do not apply to every LISTERINE product. Fluoride, alcohol-free and children’s rinses can have different amounts, rinsing times and age requirements.
Always follow the package for the exact product being used.
Listerine Products for Children
Age requirements vary substantially by formula.
For example:
- Current LISTERINE Original and other intense antiseptic formulations say not to use in children under 12.
- Current LISTERINE TOTAL CARE Kids fluoride mouthwashes are labeled for adults and children age 6 and older.
- Children using applicable fluoride rinses should be supervised until they can rinse and spit without swallowing.
For children younger than the age specified on the package, follow the label’s instructions about consulting a dentist or doctor.
Do not assume that an adult LISTERINE product and a children’s fluoride rinse have the same directions.
Alcohol-Free Listerine
LISTERINE currently offers multiple alcohol-free mouthwashes.
These include mild and extra-mild options for consumers who prefer a less intense rinse.
Current alcohol-free product categories include products designed for needs such as:
- Fresh breath
- Anticavity protection
- Tartar control
- Whole-mouth care
- Children’s fluoride oral care
Check the ingredient list and directions on the exact product rather than assuming every alcohol-free LISTERINE formula is identical.
Listerine Ingredients
Classic LISTERINE antiseptic formulations use four essential-oil active ingredients:
- Eucalyptol
- Menthol
- Methyl salicylate
- Thymol
Other LISTERINE products can use different active ingredients.
For example, current anticavity mouthwashes can contain sodium fluoride.
Inactive ingredients, flavorings, coloring and alcohol content can also vary.
For an ingredient allergy or sensitivity concern:
- Read the current bottle label.
- Check the product’s official LISTERINE page.
- Contact Consumer Care if additional clarification is needed.
Do not rely solely on the ingredient list from an older bottle or third-party retailer listing because formulas can change.
Listerine Product Has Changed Color
LISTERINE’s current FAQ explains that some packaging has changed as the company incorporates recycled material.
If the concern is the liquid itself rather than the bottle:
- Check the expiration date.
- Check whether the seal was intact.
- Check the product instructions for storage information.
- Contact LISTERINE if the appearance seems unusual.
Some current LISTERINE labels note that cold temperatures can temporarily make the product appear cloudy.
Follow the specific storage instructions for your formula.
Does Listerine Expire?
LISTERINE says most of its current products have an expiration date.
Check the bottle or packaging.
The company recommends replacing products that are past their expiration date.
If the printed expiration date or production code is unclear, contact Consumer Care with the exact product and package information.
Discontinued Listerine Products
LISTERINE maintains an official discontinued-products directory.
Current discontinued listings include a number of older mouthwashes, breath products and specialty formulas.
Examples appearing in the current discontinued section include:
- LISTERINE NATURALS Healthier Gums Herbal Mint
- LISTERINE Zero Alcohol Grapefruit Rosé
- LISTERINE TOTAL CARE Stain Remover
- LISTERINE READY! TABS
- LISTERINE COOL MINT ZERO Concentrate products
- LISTERINE Zero Alcohol Coconut & Lime
- Certain Healthy White formulations
- LISTERINE ULTRACLEAN Fresh Citrus
- LISTERINE SENSITIVITY Zero Alcohol Fresh Mint
Use the live discontinued-product directory before assuming that a missing flavor or formula is only temporarily unavailable.
Can’t Find Listerine at a Store?
A product not being stocked locally does not automatically mean it has been discontinued.
Before contacting Consumer Care:
- Check Listerine.com’s current product directory.
- Check the official Where to Buy tool.
- Check the Discontinued Products directory.
- Contact nearby retailers.
Retailers control local inventory and can change which sizes or flavors they carry.
If a product appears in LISTERINE’s current catalog but is unavailable nearby, ask the retailer whether it can be ordered.
Listerine Purchased From Another Retailer
Most LISTERINE products are purchased through:
- Pharmacies
- Grocery stores
- Mass retailers
- Warehouse clubs
- Online marketplaces
For a routine return or refund, start with the retailer’s current policy.
Contact LISTERINE separately when the issue involves:
- Product quality
- Packaging
- Ingredients
- Unexpected reaction
- Unusual taste, odor or appearance
Keep the product even if the retailer refunds the purchase because Consumer Care may still need package information.
Listerine Coupons and Promotions
LISTERINE periodically offers coupons and promotional offers through its official website and participating retailers.
Promotion availability can change.
If a coupon does not work:
- Read the expiration date.
- Check qualifying product sizes.
- Check retailer exclusions.
- Confirm whether the coupon is digital or printable.
For a retailer-specific coupon problem, the retailer may need to assist.
Use Listerine.com rather than an unknown coupon site if an offer requests personal information.
Listerine Product Safety
Use the exact product as directed on its current label.
Basic safety guidance found on current LISTERINE products includes:
- Do not swallow the mouthwash.
- Keep products out of reach of children.
- Follow the age restrictions for the exact formulation.
- Stop use and seek appropriate professional advice if an applicable label directs you to do so after irritation or new symptoms.
- Seek medical help or contact a Poison Control Center if more than the normal rinsing amount is accidentally swallowed.
For current recall information involving any oral-care product, verify information through the U.S. Food and Drug Administration and the manufacturer’s current consumer-support resources rather than relying on a social-media post.
How to Escalate a Listerine Complaint
- Call 1-888-222-0182 during current Consumer Care hours or submit the official written contact form.
- Provide the exact product, size and product codes.
- Explain what happened and the resolution you are requesting.
- Keep the bottle, cap and package.
- Keep the receipt when available.
- Save any case or reference number provided.
- If photos are requested, photograph the product and package clearly.
- Follow up using the existing case information if the first response does not resolve the issue.
If the issue involves an adverse event, clearly tell Consumer Care that you are reporting a possible side effect or reaction.
If the issue is an ordinary retailer refund rather than a manufacturing complaint, also work through the store that sold the product.
Listerine Reviews and Complaints
CustomerServiceNumbers.com currently shows no published Listerine customer reviews and a 0 out of 5 rating based on zero reviews.
There is therefore not enough first-hand CSN feedback to establish a reliable trend involving LISTERINE customer service, taste, pricing, availability or product effectiveness.
The previous version of this page stated that customer reviews often highlighted LISTERINE’s effectiveness, taste and customer service while complaints focused on customer service, product availability and pricing. Those statements were not supported by any visible CustomerServiceNumbers.com reviews and should not be presented as findings from this site’s review section.
If you have contacted LISTERINE, useful first-hand review details include:
- The product involved
- Whether the concern involved packaging, taste, ingredients, availability or a product complaint
- Whether you called or used the written contact form
- Whether you received a case number
- How long it took to receive assistance
- Whether Consumer Care resolved the issue
Do not publish medical information, personal contact information, receipts or private customer-service correspondence.
About Listerine
LISTERINE has a history dating to 1879, when the formula was developed as a surgical antiseptic.
The product was named in recognition of Joseph Lister, the surgeon associated with pioneering antiseptic surgical practices.
LISTERINE became available to consumers over the counter in 1914 and later developed into a broader oral-care brand.
Current U.S. products include:
- Antiseptic mouthwashes
- Alcohol-free mouthwashes
- Anticavity fluoride rinses
- Children’s fluoride mouthwashes
- Breath-freshening products
- Specialty oral-care products
LISTERINE is currently a brand of Kenvue Brands LLC, a subsidiary of Kenvue Inc.
Kenvue became an independent consumer-health company after separating from Johnson & Johnson in 2023.
Its current headquarters is at 1 Kenvue Way in Summit, New Jersey.
Pending Kenvue and Kimberly-Clark Transaction
Kimberly-Clark and Kenvue announced a transaction under which Kimberly-Clark plans to acquire Kenvue.
Shareholders of both companies approved the transaction in January 2026.
As of this page update, the transaction has not yet completed and Kenvue remains the current parent company of LISTERINE.
Because corporate ownership can change when the transaction closes, consumers should rely on the current Listerine.com Contact Us page for product support rather than contacting a corporate parent about an ordinary mouthwash question.
