ICF Clorexyderm Oto Ear Cleaning Solution for Dogs & Cats – 150ml

ICF Clorexyderm Oto Ear Cleaning Solution for Dogs & Cats – 150ml

ICF Clorexyderm Oto Ear Cleaning Solution is a specialist veterinary ear cleanser formulated to gently dissolve excess earwax, remove debris and support healthy ear hygiene in dogs and cats.

Containing 0.05% chlorhexidine digluconate, lactic acid, salicylic acid and propylene glycol, Clorexyderm Oto combines antimicrobial, acidifying and wax-removing properties in a non-oily solution.

With an acidic pH of approximately 3.5, the formula helps create an ear canal environment less favourable to the overgrowth of certain bacteria and yeasts, including Malassezia, a common organism associated with canine ear problems.

Clorexyderm Oto is particularly useful for dogs prone to recurrent ear issues, animals with floppy ears, pets who regularly swim and dogs with allergies that predispose them to ear inflammation.

Suitable for adult dogs, puppies, cats and kittens, it can be used for routine ear cleaning or as part of a veterinary-directed ear care programme.

How Does Clorexyderm Oto Work?

Clorexyderm Oto combines four principal ingredients that work together to support ear cleanliness and hygiene.

Chlorhexidine Digluconate – 0.05%

Chlorhexidine is an antiseptic widely used in veterinary dermatology.

It has antimicrobial activity against many Gram-positive bacteria, some Gram-negative bacteria and certain yeasts.

In Clorexyderm Oto, chlorhexidine helps control susceptible microorganisms within the external ear canal.

Its antimicrobial activity complements the acidifying action of lactic acid.

The concentration is relatively low compared with some other chlorhexidine-containing veterinary preparations, reflecting its intended role as a maintenance cleanser.

Lactic Acid – 2.5%

Lactic acid is responsible for the acidifying properties of Clorexyderm Oto.

The manufacturer describes the finished solution as having a pH of approximately 3.5.

Maintaining an acidic ear canal environment can help discourage the proliferation of certain bacteria and yeasts.

This is particularly relevant for animals prone to recurrent yeast-associated ear problems.

Salicylic Acid – 0.1%

Salicylic acid has keratolytic properties, meaning it helps loosen and break down accumulated keratin-containing debris.

In an ear-cleaning formulation, this can help with the removal of:

• Excess earwax
• Greasy deposits
• Dead skin cells
• Surface debris
• Accumulated material within the external ear canal

By helping remove these materials, salicylic acid supports more effective cleaning.

Propylene Glycol – 10%

Propylene glycol is included as a solvent and cleansing ingredient.

It contributes to the formulation's ability to soften and dissolve accumulated earwax.

The manufacturer's UK brochure also describes its role in supporting the ear-cleaning action of the product.

Why Is the Acidic pH Important?

The normal ear canal environment plays an important role in controlling microbial growth.

When the ear becomes inflamed or retains excessive moisture, conditions may become more favourable for bacterial and yeast overgrowth.

Clorexyderm Oto has an acidic pH of approximately 3.5, which supports its role as an antifungal maintenance cleanser.

The manufacturer's UK brochure specifically recommends it for animals where yeast is a recurring concern.

However, an acidic formulation may sting when applied to severely inflamed, ulcerated or damaged ear canals. Veterinary assessment is important before use in painful ears.

Clorexyderm Oto for Yeast-Prone Ears

One of the principal uses of Clorexyderm Oto is the maintenance of ears prone to yeast overgrowth.

Malassezia pachydermatis is a yeast commonly found on dogs' skin and in their ears. It may proliferate when underlying conditions alter the normal ear environment.

Dogs with environmental allergies are particularly susceptible to recurrent yeast-associated ear problems.

Common signs include:

• Brown or dark waxy discharge
• A musty or unpleasant smell
• Ear redness
• Itching and scratching
• Frequent head shaking
• Greasy debris
• Recurrent discomfort

Clorexyderm Oto may help maintain ear hygiene and reduce the conditions favouring microbial overgrowth.

Important: It is not a guaranteed standalone treatment for an established yeast infection. Veterinary examination and cytology may be necessary to identify the cause and determine whether prescription antifungal medication is required.

Particularly Useful for Floppy-Eared and Swimming Dogs

The manufacturer highlights Clorexyderm Oto as a useful maintenance cleaner for dogs whose ear anatomy or lifestyle can contribute to increased warmth and moisture.

Examples include:

• Labrador Retrievers
• Cocker Spaniels
• Springer Spaniels
• Basset Hounds
• Other breeds with pendulous ears
• Dogs that swim regularly
• Dogs with recurring allergic ear inflammation

Its non-oily formulation and acidifying properties make it a practical option for appropriate maintenance routines.

Not every dog with floppy ears needs routine ear cleaning. The frequency should be based on the individual dog's ear health.

Recommended Clorexyderm Oto Cleaning Schedules

The manufacturer publishes slightly different maintenance frequencies in its UK brochure and international product instructions.

Reason for Use	Published Guidance
Routine maintenance – UK brochure	1–2 times weekly
Routine maintenance – international instructions	2–3 times weekly
Wax and debris management	2–3 times weekly, or as advised by a vet
Before prescribed ear medication	Clean using the manufacturer's method when directed by a vet
Recurrent yeast-prone ears	Maintenance schedule tailored by the vet
After swimming	May be used as part of an appropriate ear care routine

Routine Ear Hygiene

The UK manufacturer's brochure recommends using Clorexyderm Oto once or twice per week to maintain healthy ears.

This may be appropriate for dogs requiring regular cleaning because of recurring wax accumulation or a history of ear problems.

Regular Maintenance for Wax-Prone Ears

The manufacturer's international instructions recommend application two or three times weekly.

This schedule is intended for routine ear cleaning and preparation before medical treatment.

Veterinary Management of Recurrent Otitis

A published clinical investigation in allergic dogs prone to recurrent otitis used a protocol of:

• Once daily for the initial 14 days
• Followed by once weekly for three months

This was a research protocol, not the standard consumer maintenance schedule. It should not be adopted as treatment for an active infection without veterinary guidance.

Dogs with recurrent otitis may need ear cytology, treatment of underlying allergies and periodic reassessment.

After Swimming

The UK manufacturer identifies Clorexyderm Oto as useful for dogs whose ears retain moisture after swimming.

The product may form part of a preventative cleaning routine where recommended.

It is not necessary to use an ear cleanser after every swim unless the individual dog benefits from doing so.

How to Use Clorexyderm Oto

Follow the manufacturer's instructions and any advice from your veterinary surgeon.

1. Check the ears: Do not clean a severely painful, swollen or bleeding ear without veterinary assessment.
2. Lift the ear flap: Gently expose the opening of the external ear canal.
3. Apply the solution: The manufacturer's international directions describe placing a few drops into the ear. The UK brochure describes filling the ear canal sufficiently for cleaning. Follow the directions supplied with your bottle or your vet's advice.
4. Massage the ear base: Massage gently for approximately 30–60 seconds to distribute the cleanser and loosen wax.
5. Allow your pet to shake: Let the dog or cat shake their head if comfortable.
6. Remove excess liquid: Wipe away loosened wax and debris from the visible outer ear with cotton wool, gauze or a clean soft cloth.
7. Clean the applicator: Wipe the nozzle carefully after use to reduce contamination.
8. Repeat as directed: Use according to the appropriate maintenance schedule or veterinary instructions.

Do not insert cotton buds deep into the ear canal.

Do not force the nozzle into the ear or perform deep ear flushing without veterinary instruction.
