Calmoseptine with Menthol: Uses and Applications
Calmoseptine with menthol is a topical barrier ointment that provides cooling relief for skin irritation, pruritus (itching), and minor skin discomfort while protecting the skin from moisture and irritants.
Composition and Mechanism of Action
Calmoseptine contains menthol as one of its active ingredients. Menthol is a naturally occurring cyclic terpene alcohol derived from plants, primarily from the peppermint plant (Mentha x piperita). It works through several mechanisms:
- Activates TRPM8 receptors (cold-sensing receptors) in the skin, creating a cooling sensation 1, 2
- Acts as a counter-irritant by initially stimulating and then desensitizing nociceptors 3
- Provides a cooling effect that can temporarily relieve itching and discomfort 4
Primary Uses
Calmoseptine with menthol is primarily used for:
Skin Protection: Creates a moisture barrier to protect skin from irritation caused by:
- Incontinence (urine or fecal)
- Wound drainage
- Fistula drainage
- Perspiration
Symptomatic Relief: Provides temporary relief for:
- Pruritus (itching) 4
- Minor skin irritation
- Diaper rash
- Moisture-associated skin damage
- Peristomal skin irritation
Clinical Applications
Pruritus Management
Menthol is recommended as a cooling antipruritic agent for generalized pruritus of unknown origin (GPUO) 4. It works through a counter-irritant effect rather than a true antipruritic effect compared to vehicle control.
- Strength of recommendation: D (Level of evidence 4) according to British Association of Dermatologists' guidelines 4
- Application: Can be applied as needed to affected areas
Acute Viral Cough
Menthol by inhalation suppresses the cough reflex and may be prescribed as menthol crystals or proprietary capsules 4. The cough suppression is acute and short-lived.
Skin Cooling and Pain Relief
Menthol (16%) is an FDA-approved active ingredient in topical analgesic products for temporary relief of minor aches and pains of muscles and joints due to:
- Simple backache
- Arthritis
- Strains
- Bruises
- Sprains 5
Urticaria and Angio-oedema
Cooling antipruritic lotions containing menthol (such as 1% menthol in aqueous cream) can be soothing for patients with urticaria and angio-oedema 4.
Intrahepatic Cholestasis of Pregnancy (ICP)
Topical menthol creams may be used for symptomatic relief of pruritus in ICP, although they have limited use because itching is typically widespread 4.
Administration Guidelines
- Application: Apply a thin layer to clean, dry skin as needed or as directed
- Frequency: Can be applied 2-4 times daily or after each incontinent episode
- Special instructions:
- Clean and dry the affected area before application
- Can be used under wound dressings
- Compatible with most incontinence products
Precautions and Limitations
Avoid application to:
- Deep or puncture wounds
- Serious burns
- Eyes or mucous membranes
Discontinue use if:
- Condition worsens
- Symptoms persist for more than 7 days
- Excessive irritation develops
Menthol's cooling effects are temporary and may not address underlying conditions 6
High concentrations of menthol may potentially cause cold allodynia (pain in response to normally non-painful cold stimuli) 3
Alternative Treatments
For pruritus management, if menthol is ineffective, consider:
- Topical doxepin (limited to 8 days, 10% of body surface area, maximum 12g daily) 4
- Topical clobetasone butyrate 4
- Systemic antihistamines 4
For erythromelalgia, other topical options include:
- Compounded midodrine 0.2%
- Clonidine transdermal patches (0.1-0.3mg daily) 4
Remember that while menthol provides symptomatic relief, addressing the underlying cause of skin irritation or pruritus is essential for long-term management.
