Descutan (Chlorhexidine Gluconate)
Antiseptic skin cleanser for pre-operative infection prevention
Quick Facts About Descutan
Key Takeaways About Descutan
- Pre-surgical antiseptic wash: Descutan is used to cleanse the entire body and hair before surgery to reduce the risk of surgical site infections caused by skin bacteria
- Long-lasting protection: Chlorhexidine binds to the skin and continues to kill bacteria for hours after washing, providing sustained antimicrobial protection through to the operating room
- Do not use regular soap afterwards: After washing with Descutan, you must not use ordinary soap, shampoo, conditioner, or body lotion, as these products neutralize the antiseptic effect
- Keep away from eyes and ears: Descutan must not come into contact with the eyes, as it can cause serious corneal damage. Cotton wool in the ears is recommended to prevent hearing damage
- Caution in newborns: Chlorhexidine can cause chemical burns on the skin of neonates, particularly premature infants, and must be used with great care in this population
What Is Descutan and What Is It Used For?
Descutan is a bactericidal antiseptic skin cleanser containing chlorhexidine gluconate 4%. It is used primarily for pre-operative whole-body washing to reduce skin bacteria and help prevent surgical site infections (SSIs). The product comes as a medicated sponge for body washing and a cutaneous solution for hair washing.
Descutan belongs to the biguanide class of antiseptics and contains chlorhexidine gluconate as its active ingredient at a concentration of 40 mg/ml (4%). Chlorhexidine is one of the most widely used antiseptic agents in healthcare settings worldwide and has been a cornerstone of infection prevention protocols for decades. The World Health Organization (WHO) includes chlorhexidine on its List of Essential Medicines, recognizing its fundamental importance in global healthcare.
The primary purpose of Descutan is to reduce the microbial burden on the patient's skin before surgical procedures. Surgical site infections remain one of the most common healthcare-associated infections globally, affecting an estimated 2–5% of patients undergoing inpatient surgery according to WHO data. Pre-operative skin preparation with chlorhexidine-based products like Descutan is a key evidence-based strategy recommended by international guidelines for reducing this risk.
Chlorhexidine works by disrupting bacterial cell membranes. At low concentrations, it acts as a bacteriostatic agent, inhibiting bacterial growth. At the higher concentration found in Descutan (4%), it is bactericidal, meaning it actively kills bacteria. It is effective against a broad spectrum of microorganisms, including Gram-positive bacteria (such as Staphylococcus aureus and Streptococcus species), Gram-negative bacteria (such as Escherichia coli and Pseudomonas aeruginosa), facultative anaerobes, aerobes, and yeasts including Candida species. However, it has limited activity against bacterial spores, mycobacteria, and non-enveloped viruses.
How Descutan Works
One of the most valuable properties of chlorhexidine is its substantivity — its ability to bind strongly to proteins in the skin and continue exerting antimicrobial activity for several hours after application. When you wash with Descutan, the chlorhexidine molecules adhere to the stratum corneum (the outermost layer of skin) and form a persistent antimicrobial layer. This residual effect means that even after rinsing off the product, the skin remains protected against bacterial recolonization for an extended period, which is particularly important in the hours between pre-operative washing and the actual surgical procedure.
The substantivity of chlorhexidine also means that repeated applications build up the antimicrobial effect. This is why Descutan washing protocols typically involve two consecutive washes: the first wash removes surface dirt, oils, and loose bacteria, while the second wash allows more chlorhexidine to bind to the now-cleaner skin surface, enhancing the cumulative antimicrobial protection.
Clinical Evidence for Pre-Operative Chlorhexidine Washing
The use of chlorhexidine-based pre-operative washing has been extensively studied and is supported by high-quality evidence. A Cochrane systematic review and multiple randomized controlled trials have demonstrated that pre-operative skin preparation with chlorhexidine reduces the incidence of surgical site infections compared to no washing or washing with plain soap. The WHO Global Guidelines for the Prevention of Surgical Site Infection (2016, updated 2018) conditionally recommend that patients shower or bathe with plain soap or an antiseptic agent before surgery, with chlorhexidine being the most widely used antiseptic for this purpose.
The National Institute for Health and Care Excellence (NICE) in the United Kingdom and the Centers for Disease Control and Prevention (CDC) in the United States both include pre-operative chlorhexidine washing in their surgical site infection prevention bundles. The European Centre for Disease Prevention and Control (ECDC) similarly recommends pre-operative skin antisepsis as part of comprehensive infection control strategies.
Descutan is designed specifically for pre-operative skin preparation and is not intended for daily hygiene use. It should be used according to the instructions provided by your healthcare team, typically on the evening before and the morning of your scheduled surgery. The product is most effective when the complete washing protocol is followed, including the double-wash technique.
What Should You Know Before Using Descutan?
Before using Descutan, you should know that it must never be applied to joints, tendons, the brain, meninges, or perforated eardrums due to neurotoxicity risk. It must not contact the eyes, as serious corneal damage can occur. Special caution is needed for neonates. There are no known risks during pregnancy or breastfeeding.
While Descutan is a well-established and generally safe antiseptic when used as directed, there are important precautions and contraindications that must be understood before use. Chlorhexidine gluconate is intended exclusively for external use on intact skin, and its application to certain body areas or in certain patient populations carries specific risks that require careful attention.
Contraindications
You must not use Descutan if:
- You are allergic (hypersensitive) to chlorhexidine gluconate or any of the other ingredients listed in the composition section of this article
- The product would come into contact with joints, tendons, the brain, or meninges (the membranes surrounding the brain and spinal cord), as chlorhexidine is toxic to nervous tissue and can cause serious neurological damage
- You have perforated eardrums (tympanic membrane perforation), as chlorhexidine entering the middle ear can cause permanent sensorineural hearing loss due to its ototoxic properties
If you are unsure whether any of these contraindications apply to you, discuss your concerns with your healthcare provider before using the product.
Warnings and Precautions
Talk to your doctor, pharmacist, or nurse before using Descutan if any of the following apply to you:
Descutan must not come into contact with the eyes. If the product accidentally enters the eyes, rinse immediately and thoroughly with large amounts of clean water. If irritation, redness, pain, or visual disturbances develop, seek medical attention immediately. Serious cases of persistent corneal damage requiring corneal transplantation have been reported when chlorhexidine-containing products accidentally contacted the eyes during surgical procedures on patients under general anesthesia.
- Skin sensitivity: If you have a history of skin reactions to antiseptics or cleaning products, inform your healthcare team. Discontinue use if significant skin irritation, redness, or rash develops
- Open wounds or broken skin: While Descutan is designed for use on intact skin, avoid applying it to large open wounds, deep cuts, or burns without specific medical guidance
- Ear protection: When washing the head and face with Descutan, take care to prevent the product from entering the ear canal. Cotton wool ear plugs are recommended during use to prevent ototoxic effects
- Previous allergic reaction: If you have ever experienced an allergic reaction to chlorhexidine in any form (including mouthwash, skin antiseptics, or coated medical devices), do not use Descutan and inform your surgical team
Children and Neonates
Descutan should be used with extra caution in newborns, particularly premature infants. The immature skin barrier of neonates makes them more vulnerable to the chemical effects of chlorhexidine, and cases of chemical skin burns have been reported in this population. The risk is highest in very premature infants (born before 32 weeks of gestation) whose skin is exceptionally thin and fragile.
For older children undergoing surgery, Descutan may be used under medical supervision, following the same general washing instructions but with additional care to avoid contact with the eyes, ears, and any areas of broken or irritated skin. The decision to use chlorhexidine-based products in pediatric patients should always be made by the healthcare team responsible for the child's care.
Pregnancy and Breastfeeding
There are no known risks associated with using Descutan during pregnancy or breastfeeding. Chlorhexidine gluconate has minimal systemic absorption when applied to intact skin, meaning that very little of the active substance enters the bloodstream. This makes it generally considered safe for external use during pregnancy and lactation. However, as with any medication or medical product, it is always advisable to inform your healthcare provider if you are pregnant, breastfeeding, think you may be pregnant, or are planning to have a baby.
Driving and Operating Machinery
Descutan does not affect your ability to drive or operate machinery. As an externally applied antiseptic with minimal systemic absorption, it has no impact on alertness, cognition, or motor function.
How Does Descutan Interact with Other Products?
The most important interaction to be aware of is that regular soaps, shampoos, conditioners, and body lotions contain anionic surfactants that neutralize the residual antimicrobial effect of chlorhexidine. After washing with Descutan, you must not use any of these products until after your surgery.
Unlike many oral medications, Descutan is applied externally to the skin and is not significantly absorbed into the body. This means it does not interact with oral medications, intravenous drugs, or other systemic treatments in the traditional pharmacological sense. However, there are important physicochemical interactions that can affect how well Descutan works on the skin surface.
Major Interactions
| Product | Effect | Recommendation |
|---|---|---|
| Regular soap | Anionic surfactants inactivate chlorhexidine and neutralize its residual antimicrobial effect on the skin | Do not use regular soap after washing with Descutan before surgery |
| Shampoo and conditioner | Surfactants and conditioning agents remove chlorhexidine from the skin and hair, eliminating the protective antimicrobial layer | Do not use shampoo or conditioner after washing hair with Descutan solution |
| Body lotion and moisturizers | Emollients and oils create a barrier between chlorhexidine and the skin surface, reducing antimicrobial efficacy | Do not apply body lotion or moisturizer after Descutan wash |
| Povidone-iodine | May form a precipitate when combined with chlorhexidine, potentially reducing the effectiveness of both agents | If both agents are needed, allow one to dry completely before applying the other |
Minor Interactions
Several other products and substances may interact with chlorhexidine on the skin surface, though these interactions are generally less clinically significant:
- Hard water: High mineral content in water can slightly reduce chlorhexidine's antimicrobial activity, though this is rarely clinically significant at the 4% concentration found in Descutan
- Alcohol-based hand sanitizers: When used sequentially, alcohol and chlorhexidine can complement each other's antimicrobial effects. There is no antagonistic interaction
- Deodorants and antiperspirants: These products may slightly interfere with chlorhexidine binding in the axillary area. Avoid applying them after the Descutan wash
- Makeup and cosmetics: Should not be applied to the face after washing with Descutan before surgery
The overarching rule after washing with Descutan is simple: do not apply any other product to your skin or hair before surgery. This preserves the full antimicrobial benefit of the chlorhexidine. Put on clean clothes, use clean towels, and change to clean bed linens after your Descutan wash.
What Is the Correct Way to Use Descutan?
Descutan is used for pre-operative body and hair washing. The medicated sponge is used for body washing and the cutaneous solution is used for hair washing. The complete washing procedure is performed twice in a single session, and is typically done on the evening before and the morning of surgery.
Descutan comes in two components designed to work together: the medicated sponge (impregnated with chlorhexidine gluconate 4%) for body washing, and the cutaneous solution (in sachets) for hair washing. The specific washing protocol may vary depending on your hospital's guidelines, but the standard procedure follows the steps outlined below. Always follow the specific instructions provided by your healthcare team, as they may differ from the general guidance based on your individual circumstances and the type of surgery you are having.
Standard Washing Instructions
- Remove your watch, rings, and all other jewelry before starting.
- Shower your entire body including your hair with water only. Then turn off the shower.
- Wash your hair using the Descutan solution from the sachet. Important: Do not allow Descutan to enter the ear canal — cotton wool ear plugs are recommended. Avoid contact with the eyes at all times.
- Open the sponge packaging and add water to moisten the sponge. Use the sponge to wash your entire body following steps 5–7.
- Wash your face, paying particular attention to the area around the nose.
- Wash your upper body, paying special attention to the armpits and navel.
- Wash your lower body, legs, and feet. Pay special attention to the genital area and groin folds.
- Rinse your entire body thoroughly with water. Turn off the shower.
- Take a new sponge and solution sachet, and repeat the entire washing procedure from step 3 through step 8 a second time.
- Dry your body with a clean towel. Do not use regular soap, shampoo, conditioner, or body lotion after washing with Descutan, as this will destroy the residual antimicrobial effect.
- Put on clean clothes and change to clean bed linens.
Adults
Standard Pre-Operative Protocol
Adults typically use one home wash pack per washing session. Each pack contains 4 medicated sponges (15 ml each) and 4 sachets of solution (10 ml each). Two sponges and two solution sachets are used per session (one for each of the two wash cycles). Sessions are usually performed on the evening before surgery and again on the morning of surgery, using the complete pack.
Children
Pediatric Use
Use in children should be under medical supervision. The same general washing technique applies, but with extra care to avoid eye and ear contact. A parent or caregiver should assist with the washing procedure. For younger children, the healthcare team may provide specific instructions regarding the amount of product to use and the areas to be washed based on the surgical site.
Neonates
Neonatal Use — Extreme Caution Required
Use with extreme caution in newborns, especially premature infants. Chlorhexidine can cause chemical skin burns in neonates due to their immature skin barrier. If use is necessary, it should only be performed by trained healthcare professionals under close medical supervision. The product should be applied minimally and rinsed off promptly. Any signs of skin reaction should be reported immediately.
Missed Dose
If you forget to perform a scheduled Descutan wash (for example, the evening wash before surgery), contact your hospital or surgical team for guidance. They may advise you to perform the wash as soon as possible or adjust the protocol. Do not skip the pre-operative washing entirely without consulting your healthcare team, as it is an important part of your infection prevention plan.
Overdose
Descutan is applied externally to the skin and is not absorbed in significant quantities. There is no recognized risk of overdose from external use. However, chlorhexidine is harmful if swallowed. If the product is accidentally ingested, seek medical attention immediately. Symptoms of ingestion may include nausea, vomiting, and irritation of the mouth and throat. Do not induce vomiting unless instructed by a poison control center or healthcare professional.
What Are the Side Effects of Descutan?
The most common side effect of Descutan is mild skin irritation, affecting more than 1 in 100 users. Rare side effects include allergic reactions, eye irritation if the product contacts the eyes, and hearing damage if it enters the ear canal. In very rare cases, anaphylactic reactions have been reported. Neonates are at risk of chemical skin burns.
Like all medicines, Descutan can cause side effects, although not everyone experiences them. Chlorhexidine gluconate has been used extensively in clinical practice for decades, and its safety profile is well established. Most side effects are mild and localized to the skin. Serious adverse reactions are rare but can occur, particularly in sensitive individuals or when the product is used improperly.
Common (affects more than 1 in 100 users)
- Skin irritation: dryness, mild itching, redness, or a feeling of tightness at the application site
- Transient skin discoloration: temporary mild staining of the skin that fades with normal washing after surgery
Rare (affects fewer than 1 in 1,000 users)
- Allergic reactions: contact dermatitis with rash, hives, or significant skin redness
- Eye irritation: redness, pain, and tearing if the product accidentally contacts the eyes
- Hearing damage: sensorineural hearing loss if the product enters the middle ear through a perforated eardrum
Frequency Not Known (reported cases)
- Anaphylactic reactions: isolated cases of severe systemic allergic reactions (anaphylaxis) have been described with external chlorhexidine gluconate use, presenting as difficulty breathing, swelling of the face or throat, severe skin rash, dizziness, or a drop in blood pressure
- Chemical burns in neonates: skin damage including blistering and erosion in newborn infants, particularly premature babies, due to the immature skin barrier
- Corneal damage: serious and potentially permanent eye damage, including persistent corneal opacification requiring corneal transplantation, reported when chlorhexidine-containing products accidentally contacted the eyes during surgical procedures on patients under general anesthesia
- Permanent visual impairment: resulting from accidental eye contact during head, face, or neck surgery under anesthesia, when the patient is unable to report pain or discomfort
What to Do If Side Effects Occur
If you experience mild skin irritation during or after using Descutan, rinse the affected area thoroughly with water. The irritation usually resolves on its own within a few hours. If the irritation persists or worsens, contact your healthcare provider for advice.
If the product accidentally contacts your eyes, rinse immediately and thoroughly with large amounts of clean water for at least 15 minutes. If eye irritation, redness, pain, or vision changes persist after rinsing, seek medical attention immediately. Do not rub the eyes.
If you develop signs of an allergic reaction such as widespread rash, hives, difficulty breathing, or swelling of the face, lips, tongue, or throat, stop using the product immediately and seek emergency medical care. Inform your surgical team of the reaction so that alternative antiseptic agents can be used for your surgery.
It is important to report suspected side effects to your healthcare provider or to your national medicines regulatory authority. Reporting helps to continuously monitor the benefit-risk balance of medicines and contributes to patient safety for all users.
How Should You Store Descutan?
Store Descutan out of the sight and reach of children. Use before the expiration date printed on the packaging. Do not dispose of Descutan via wastewater or household waste — return unused product to your pharmacy for proper disposal.
Descutan should be stored at room temperature and kept away from direct sunlight and excessive heat. There are no special temperature requirements for storage. The product should be kept in its original packaging until ready for use, and each sponge and solution sachet should remain sealed until the time of washing.
Check the expiration date printed on the outer carton before each use. The expiration date refers to the last day of the stated month. Do not use Descutan after this date, as the antimicrobial effectiveness may be reduced and the excipients may have degraded.
Disposal
Used sponges and empty solution sachets can be disposed of with regular household waste. However, unused or expired Descutan products should not be poured down the drain or thrown in household rubbish. Instead, return them to your local pharmacy for environmentally safe disposal. These measures help protect the environment from unnecessary chemical contamination.
What Does Descutan Contain?
The active substance in Descutan is chlorhexidine gluconate at a concentration of 40 mg/ml (4%). Inactive ingredients include a surfactant system, isopropanol, D-gluconolactone, and purified water. The product is available in home wash packs and hospital packs.
Active Ingredient
The active substance is chlorhexidine gluconate 40 mg/ml (equivalent to a 4% w/v concentration). Chlorhexidine gluconate is the water-soluble salt form of chlorhexidine, chosen for its excellent stability, aqueous solubility, and favorable skin compatibility. The 4% concentration provides optimal bactericidal activity for pre-operative skin preparation while maintaining acceptable skin tolerability for most patients.
Excipients (Inactive Ingredients)
The formulation contains the following inactive ingredients that serve important roles in the product's performance:
- Polyoxyethylene-polyoxypropylene condensate — a non-ionic surfactant that provides cleansing and foaming action without interfering with chlorhexidine's antimicrobial activity (unlike anionic surfactants found in regular soaps)
- Fatty acid amidoalkyl dimethylamine oxide — an amphoteric surfactant that enhances the cleansing properties and compatibility of the formulation
- Isopropanol — acts as a co-solvent and provides additional immediate antimicrobial activity
- D-gluconolactone — a polyhydroxy acid used as a stabilizer and pH regulator
- Purified water — serves as the primary solvent

Frequently Asked Questions About Descutan
Descutan is an antiseptic skin cleanser containing chlorhexidine gluconate 4%. It is used primarily for pre-operative whole-body washing to reduce the number of bacteria on the skin and help prevent surgical site infections. The product comes as a medicated sponge for body washing and a solution for hair washing, and is used in the days leading up to planned surgery as part of a hospital's infection prevention protocol.
Descutan is typically used on the evening before and the morning of surgery. First, shower with water only and turn off the shower. Wash your hair with the Descutan solution from the sachet, avoiding the ears and eyes. Then use the medicated sponge, moistened with water, to wash your entire body from face to feet, paying extra attention to armpits, navel, groin, and genital area. Rinse off with water and repeat the entire wash a second time with a fresh sponge and sachet. After washing, do not use regular soap, shampoo, conditioner, or body lotion, and put on clean clothes with clean bed linens.
Common side effects include mild skin irritation such as dryness, itching, or redness (affecting more than 1 in 100 users). Rare side effects include allergic reactions, eye irritation if the product contacts the eyes, and hearing damage if it enters the ear canal through a perforated eardrum. In very rare cases, severe allergic reactions (anaphylaxis) have been reported. Neonates, especially premature infants, are at risk of chemical skin burns. If serious side effects occur, stop using the product and seek medical attention.
No. After washing with Descutan, you should not use regular soap, shampoo, conditioner, or body lotion. These products contain anionic surfactants and other ingredients that neutralize the residual antimicrobial effect of chlorhexidine, significantly reducing its effectiveness in preventing surgical infections. The protective antimicrobial layer that chlorhexidine forms on your skin is a key part of its benefit, and using other products would remove this protection before your surgery.
There are no known risks associated with using Descutan during pregnancy or breastfeeding. Chlorhexidine gluconate has minimal systemic absorption when applied to intact skin, meaning very little enters the bloodstream. It is generally considered safe for external use during pregnancy and lactation. However, as with any medication, it is always advisable to inform your healthcare provider about your pregnancy or breastfeeding status before using the product.
Descutan should be used with great caution in newborns, particularly premature infants, as chlorhexidine can cause chemical burns on their delicate, immature skin. For older children, the product may be used under medical supervision with the same general technique as for adults, but with extra care to prevent eye and ear contact. Always follow the specific instructions provided by your child's surgical team regarding the use of Descutan or alternative antiseptic products.
