What is hydrocortisone valerate cream 0.2 used for

Crisaborole 2% ointment is a phosphodiesterase type-4 (PDE4) inhibitor modestly effective for short-term treatment of mild to moderate atopic dermatitis, but use can be limited by patient report of discomfort. Cost is also a limiting factor.

Oral antihistamines (e.g., hydroxyzine, diphenhydramine) have not been shown to be effective and are generally not recommended but may be useful in controlling pruritus and inducing sedation, restful sleep, and prevention of scratching during sleep. Doxepin and other tricyclic antidepressants also have antihistamine effect, induce sleep, and reduce pruritus.

The topical immunomodulators pimecrolimus and tacrolimus can be used in conjunction with topical corticosteroids and are useful for the face and intertriginous sites, where steroid-induced atrophy may occur. The FDA recommends limiting their use for short periods in a specific subset of patients, given concerns about the potential for rare, carcinogenic effects. Pimecrolimus cream 1% has anti-inflammatory effects secondary to blockage of activated T-cell cytokine production. Tacrolimus ointment (0.03% or 0.1%) suppresses humoral and cell-mediated immune responses.

Oral prednisone, intramuscular triamcinolone, psoralen, ultraviolet A light therapy, and Goeckerman regimen are generally reserved for severe cases.

Cyclosporine, azathioprine, and methotrexate are sometimes tried for recalcitrant disease in adults by physicians who specialize in severe inflammatory skin conditions.

The monoclonal antibody dupilumab has been shown to be effective in children and adults with moderate to severe atopic dermatitis. It can be used with or without topical steroids and is injected subcutaneously. Cost is a limiting factor.

Antistaphylococcal antibiotics are effective in treating secondary skin infections.

John Decker (Part II)

CASE DISCUSSION

Although xerosis is certainly the most common cause of pruritus in the elderly population, it is not generally accompanied by the intense erythema with which Mr. Decker presents. Tinea cruris can produce erythema and itching, but the clinical picture differs from this dry confluent exanthem. The hallmarks of scabies, seen in nursing home populations, are linear excoriations and papules involving the intertriginous spaces and web spaces of the hands and feet.

Minimal trauma can produce the excoriations and tears in atrophic elderly skin. Scratching exacerbates the extravasation of blood into the superficial skin layers.

Because his move to the nursing care facility and changes in his medication predate the onset of Mr. Decker's generalized skin eruption, a drug-related eruption must be ruled out.11 A punch biopsy from the margin of the exanthem on the abdominal wall was taken. Sutures were placed at the biopsy site for additional help with hemostasis because the patient was on warfarin (Coumadin). The pathologist's report suggested drug eruption with eosinophilia or the urticarial phase of bullous pemphigoid.

Mr. Decker's pruritus was treated with an oral antihistamine, hydroxyzine(Atarax) 25 mg, topical hydrophilic ointment with a mid-potency steroid hydrocortisone valerate(Westcort) 0.2% added to the ointment, and an intramuscular injection of triamcinolone(Kenalog) 40 mg.

The most likely offending drugs simvastatin (Zocor) and furosemide (Lasix) were discontinued, ethacrynic acid was substituted for furosemide, and exanthem resolved over a 1-week period.

The irritated temporal dermatoses were excised by shave technique with electrodesiccation to the base of the lesion, and pathologic interpretation revealed squamous cell carcinoma (SCC).

Alice Fay Jackson (Part I)

Mrs. Jackson, a 58-year-old black elementary school teacher, complains of a 4-day history of skin sensitivity and aching of the area on the left side of her back extending to her axilla, which has prevented her from wearing her bra. Yesterday she noticed a patch of small painful blisters on her upper left abdomen (Plate 12). She has been applying calamine lotion to the area since the blisters appeared and taking ibuprofenMotrin) without relief. She had an injection of cortisone a week ago in her family doctor's office to help relieve her back pain resulting from osteoarthritis. She sleeps with a heating pad under her back at night when her back pain flares.

Her prescribed medications include famotidine (Pepcid) for indigestion and hormone replacement therapy after a hysterectomy for uterine fibroids and menorrhagia.

On physical examination, you note some conjunctival pallor, but her skin is finely textured and relatively free of wrinkles. She has a sprinkling of 2-mm black papules across her nose and cheeks (Plate 13).

Erythematous papules and vesicles arising just lateral to her spine trace the T5 dermatome around to the anterior axillary line on the left, and the area is tender to palpation. Her sacral area appears hyperpigmented and mottled with a reticular erythematous pattern, fairly well demarcated in an oval shape approximately 8 × 10 cm.

Atopic Dermatitis

Rick D. Kellerman MD, in Conn's Current Therapy 2021, 2021

Topical and Systemic Medications

The first-line medication for AD is a topical corticosteroid (TCS). For mild AD, a TCS with group VI and VII potency (Table 2) may suffice. However, for moderate to severe AD, a TCS with at least group III to V potency is chosen to increase efficacy and to shorten the duration of need for these medications.

The use of TCS is confronted with various obstacles, including rare side effects such as skin atrophy, but mostly patients’ or parents’ misunderstanding of TCS. Studies have shown that twice-daily use of fluticasone propionate (Cutivate) 0.05% cream (group V) and desonide (DesOwen, Tridesilon) 0.05% ointment or aqueous gel (group V and VI, respectively) continuously up to 1 month in young children with AD results in no significant adverse effect. It is therefore important to clarify for patients or parents the safety and side effects based on the potency of the TCS.

Topical calcineurin inhibitors (TCI) (pimecrolimus [Elidel] 1% cream and Protopic/tacrolimus ointment) are alternative nonsteroidal antiinflammatory medications for AD. Elidel is indicated for mild to moderate AD in patients older than 2 years, whereas 0.03% and 0.1% Protopic are indicated for moderate to severe AD in patients 2 to 15 years old and in patients 16 years old or older, respectively. Both Elidel and Protopic have an FDA black box warning saying that their long-term use may be associated with cancer risk. However, a recent large longitudinal study has failed to confirm this risk. These medications continue to be useful alternatives for skin areas that are prone to atrophy, including the face, axillae, and groins.

A third class of topical medication, phosphodiesterase 4 inhibitor (crisaborole [Eucrisa] 2% ointment), has been approved by the FDA for patients 2 years and older with mild to moderate AD. A biologic dupilumab (Dupixent), which targets IL-4 and IL-13, has also been approved by the FDA for patients 12 years and older with moderate to severe AD.

Wet-wrap treatment, phototherapy, and systemic immunosuppressive therapies (e.g., cyclosporine [Sandimmune, Neoral],1 azathioprine [Imuran],1 methotrexate [Trexall],1 and mycophenolate mofetil [CellCept])1 are alternatives, but not approved by FDA, for severe AD patients. Because of the potential serious adverseeffects associated with these treatments, referral to an allergist or dermatologist is recommended before their initiation.

Systemic corticosteroids usually are not recommended for AD because of their known adverse effects, including stunted growth in children, adrenal suppression, osteoporosis, and cataracts. A rebound of AD symptoms is common after the medication is stopped. If a systemic corticosteroid is used, it should be tapered over a short period (e.g., a week) while topical antiinflammatory treatment is intensified.

The efficacy and side effects of the following medications have not been established in AD: intravenous immunoglobulin (IVIG),1 anti-IgE (omalizumab [Xolair]),1 probiotics,7 montelukast (Singulair),1 Chinese medicinal herbs, and fish oils.1

Atopic Dermatitis

A. Wesley Burks MD, in Middleton's Allergy: Principles and Practice, 2020

Corticosteroids.

Corticosteroids reduce inflammation and pruritus and are effective for both the acute and chronic components of AD. They affect multiple resident and infiltrating cells primarily through suppression of inflammatory genes, reducing inflammation and pruritus. Topical corticosteroids are available in a wide variety of formulations, ranging from extremely high-potency (group 1) to low-potency (group 7) preparations (Table 33.2). The vehicle in which the product is formulated can alter the potency of the corticosteroid and move it up or down in this classification. Generic formulations of topical corticosteroids are required to have the same active ingredient and the same concentration as the original product. However, many generics do not have the same vehicle formulation, and the bioequivalence of the product can vary significantly.

Choice of a particular product depends on the severity and distribution of skin lesions. In general, an effective topical corticosteroid of the lowest potency should be used. However, choosing a preparation that is too weak may result in persistent or worsening AD. Resistant lesions may respond to a potent topical corticosteroid under occlusion, although this needs to be used cautiously to prevent irreversible atrophic changes. When treating pediatric patients, clinicians should be aware of age-appropriate indications (e.g., fluticasone 0.05% cream, up to 28 days in children age ≥3 months; fluticasone lotion, ≥12 months of age; mometasone cream/ointment, ≥2 years of age).

With appropriately used low- to medium-potency topical corticosteroids, side effects are infrequent. Thinning of the skin with telangiectasias, bruising, hypopigmentation, acne, striae, and secondary infections may occur. The face, particularly the eyelids, and the intertriginous areas are especially sensitive to these adverse effects, and only low-potency preparations should be used routinely on these areas. Perioral dermatitis, characterized by erythema, scaling, and follicular papules and pustules that occur around the mouth, in the alar creases, and sometimes on the upper lateral eyelids, can occur with the use of topical corticosteroids on the face. “Steroid addiction” describes an adverse effect primarily of the face of adult women treated with topical corticosteroids, who complain of a burning sensation. Patients improve with total discontinuation of the corticosteroid therapy.177 High-potency topical corticosteroids must be used cautiously, especially under occlusion, because they may lead to significant atrophic changes and systemic side effects.

Topical corticosteroids are available in a variety of bases, including ointments, creams, lotions, solutions, gels, sprays, oil, and even tape (Table 33.2). Therefore no need exists to compound these medications. Ointments are most occlusive and as a rule provide better delivery of the medication while preventing evaporative losses. In addition, ointments spread more evenly than other creams or solutions. In a humid environment, creams may be better tolerated than ointments, because the increased occlusion can cause itching or even folliculitis. In general, however, creams and lotions, although easier to spread, are less effective and can contribute to skin dryness and irritation. Solutions can be used on the scalp and hirsute areas, although the alcohol content can be irritating, especially if used on inflamed or open lesions, and additives used to formulate the different bases can cause sensitization. Furthermore, allergic contact dermatitis to the corticosteroid molecule is being recognized with increasing frequency.61 This diagnosis is often difficult to establish clinically, because it can present as acute or chronic eczema.

Atopic Dermatitis

Albert C. Yan, ... Jonathan M. Spergel, in Comprehensive Pediatric Hospital Medicine, 2007

Pruritus and Inflammation

Children with AD often require topical anti-inflammatory agents to reduce pruritus and inflammation. When selecting topical agents, the choice of vehicle is important in terms of both efficacy and compliance. Ointments are more occlusive and tend to contain fewer ingredients and less alcohol and therefore cause less stinging and burning; however, they may leave the patient feeling greasy. Ointments are best tolerated by infants and young children. Creams are less occlusive, have a greater propensity to cause stinging and burning, but may be better tolerated by older children and adults. Lotions and solutions are generally less effective emollients and contain higher concentrations of alcohol, but these may be better tolerated in hair-bearing areas such as the scalp.

Topical Corticosteroids

There is extensive experience in the use of topical corticosteroids, and these agents are safe when used under appropriate medical supervision. They act by binding to cytoplasmic receptors and translocating to the nucleus, where they decrease the transcription of a variety of proinflammatory cytokines, thereby reducing inflammation. The choice of topical corticosteroid should be based on the patient's age, the anatomic site being treated, and the disease severity. Although high-potency topical steroids are more effective than low-potency agents, they are also associated with a greater risk of side effects, including cutaneous atrophy and striae, Cushing syndrome, and hypothalamic-pituitary-adrenal axis suppression.

Low-potency topical corticosteroids (e.g., hydrocortisone acetonide 1% or 2.5%, desonide 0.05%, alclometasone 0.05%) can be used safely on all areas of the body, including the face or intertriginous areas for short periods. Medium-potency agents (e.g., fluocinolone 0.025%, hydrocortisone valerate 0.2%, triamcinolone 0.1%, fluticasone 0.05%) may be necessary for patients with more active disease. These agents should be avoided on the face and intertriginous areas and warrant closer medical supervision. High-potency corticosteroids (e.g., fluocinonide 0.05%, desoximetasone 0.25%, betamethasone dipropionate 0.05%) may be considered for short-term, supervised use for recalcitrant disease on the hands and feet.

Topical Calcineurin Inhibitors

Topical calcineurin inhibitors have been approved by the Food and Drug Administration (FDA) for the treatment of AD. Tacrolimus (Protopic) 0.03% and 0.1% ointment and pimecrolimus (Elidel) 1% cream are macrolide immunosuppressive agents that act by binding to cytoplasmic macrophilin receptors; they reduce inflammation by decreasing the production of proinflammatory cytokines through actions on the NF-k B pathway. Because these agents are nonsteroidal, they do not have the side effects of the topical corticosteroids. As a result, both agents can be used on any affected cutaneous surface, including the face, eyelids, and perineal area. Both carry an indication for the treatment of acute flares of AD as well as for long-term, intermittent therapy.

Pimecrolimus is available as a 1% cream and is indicated for the treatment of mild to moderate AD. Topical tacrolimus is available as an ointment in both 0.03% and 0.1% concentrations; these are indicated for the treatment of moderate to severe AD. For both agents, application twice daily is recommended for optimal effect. Topical tacrolimus appears to have greater efficacy but is also somewhat more irritating than pimecrolimus.

In February 2005 the FDA issued a public health advisory regarding the use of topical calcineurin inhibitors, citing the increased risk of lymphoma and skin cancers observed in animal studies in which very high doses of the drugs were ingested or applied to the skin.17 It is unclear whether clinically useful doses of topical calcineurin inhibitors pose any significant risk to humans. Population-based studies, as well as most laboratory and theoretical models, have not found an increased incidence of cancer among pediatric and adult patients using either medication.18 At this time, the FDA recommends that both tacrolimus and pimecrolimus continue to be considered as second-line agents in the treatment of AD. Manufacturers of both agents have established long-term patient registries in an effort to gather safety information. Both drugs continue to represent useful additions to the pharmacopeia for AD.

Antihistamines

Studies have reached conflicting conclusions regarding the efficacy of antihistamines for the pruritus of AD. If patients complain of nighttime itching, it may be helpful to try using a sedating antihistamine at night. If the child has a beneficial response, the medication can be continued. Sedating antihistamines such as hydroxyzine, cetirizine, diphenhydramine, and doxepin appear to be more effective than less sedating antihistamines.

Systemic Corticosteroids

Prednisone, prednisolone, methylprednisolone, and dexamethasone are more commonly prescribed for patients with asthma than for those with AD. Many patients who suffer from both disorders note that although their asthma may improve following systemic therapy, they experience flares of AD following steroid withdrawal. Some clinicians have anecdotally observed that patients receiving multiple courses of systemic steroids subsequently suffer from more brittle AD; however, it is also possible that patients with more severe AD are treated with systemic steroids more often than are those with less severe disease. In general, in patients who suffer from AD alone, the use of systemic steroids should be avoided. If steroids are necessary for the management of other comorbid conditions such as asthma, they should be tapered gradually over 7 to 14 days, and topical steroids should be instituted as part of the regimen to minimize the potential for AD flare with steroid withdrawal.

Wet Wraps

An effective method that may obviate the need for systemic corticosteroids involves the use of wet wraps. This technique can be initiated while the child is an inpatient and continued on an outpatient basis if necessary. After the patient is bathed in lukewarm water, a low-potency topical steroid is applied to all affected areas of skin. Soft, moist, water-soaked dressing material (e.g., Tubifast)—with excess water removed by squeezing—is applied to the skin, followed by a layer of similar dry dressing. This can be continued for 1 to 2 weeks. Application of the topical steroid under occlusion promotes penetration as well as hydration of the skin. At home, the child can substitute moist cotton pajamas for the water-soaked dressing.

Alternative Agents

Patients who suffer from severe AD may be prescribed other medications or therapeutic options.19 Ultraviolet (UV) light has a number of effects on the skin; in patients with AD, it reduces the presence of cutaneous inflammatory T cells. Patients on UV treatment may have tanned skin and run the risk of ultraviolet light burns, especially those receiving photosensitizing agents as part of their therapy.

Cyclosporine, a potent, broad-spectrum, systemic immunosuppressive, has been used successfully in patients with severe, recalcitrant AD. Its use is limited, however, by the potential side effects, ranging from nausea, fatigue, and hirsutism to hypertension, renal insufficiency, immune suppression, and increased risk for malignancy.

Methotrexate, a well-known antimetabolite anti-inflammatory agent, improves the clinical findings in some patients with severe AD. Its use is limited by potential mucositis, marrow suppression, hepatotoxicity, and, less commonly, pulmonary complications.

The cytokine interferon-γexerts its effects on patients with AD through the inhibition of IgE synthesis, the depletion of activated EG2-reactive eosinophils, and the decrease in circulating CD25+-activated T cells, thereby reducing IL-4 and IL-5. This medication is typically administered subcutaneously three times a week for 4 to 12 weeks. Fever, myalgia, respiratory symptoms, and hepatic dysfunction (elevated lactate dehydrogenase or transaminitis) are the principal adverse effects.

A few case reports have documented the use of the potent broad-spectrum immunosuppressives azathioprine and mycophenolate mofetil, but they carry the side effects of immune suppression and an increased risk for malignancy. Of note, patients who are deficient in the enzyme thiopurine S-methyltransferase may suffer severe marrow suppression when azathioprine or its derivatives are administered.

Eczematous Eruptions in Childhood

Amy S. Paller MD, Anthony J. Mancini MD, in Hurwitz Clinical Pediatric Dermatology (Fourth Edition), 2011

Topical antiinflammatory medications

Topical corticosteroids have been the mainstay of treatment for AD (Table 3.2), and are available in a wide range of potencies from the weakest class VII corticosteroids (e.g., hydrocortisone acetate) to the ultrapotent class I steroids (Table 3.3). The use of more potent topical corticosteroids, particularly when applied to large surface areas, under occlusion or for long periods of time, may lead to adverse effects (Table 3.4). The face and intertriginous areas are the most susceptible sites, and may show local effects, even when weaker steroids are used for prolonged periods (Fig. 3.28). Because of their increased body surface area-to-weight ratio, small children have the greatest risk of systemic absorption of topically applied steroids. Concern about the use of topical steroids has led to ‘steroid phobia’ among families and even physicians.99 As a result, compliance may be decreased and weak topical steroids insufficient for adequate control may be used.

In general, group I corticosteroids are not recommended for patients younger than the age of 12 years, should not be used in intertriginous areas or under occlusion, and require a rest period after 14 days of use. Use of this group of ultrapotent steroids is usually reserved for lichenified plaques and recalcitrant dermatitis of the hands and feet, and should be limited. Considering the widespread use of topical corticosteroids, few local adverse reactions occur when topical steroids are carefully chosen and used appropriately based on site of application and severity of the dermatitis.100 As such, even potent topical corticosteroids may safely be used in small areas for short periods of time.

The choice of treatment will depend on the severity and localization of the dermatitis, the age of the pediatric patient, and the history of use of topical antiinflammatory agents. The least potent preparation that adequately controls the disease process should be used. For children with mild to moderate disease, intermittent use of a low strength topical steroid with emollient application to maintain clearance usually suffices. However, children with moderate to severe disease often show a cycle of rapid recurrent flaring when topical antiinflammatory suppression is discontinued. A commonly used regimen to maintain control in these children while minimizing the risk of chronic steroid application is to apply mid-potency to potent topical steroids for acute flares (e.g., for a few days to up to 2 weeks twice daily) followed by intermittent therapy with topical steroid101 or, to avoid continuing steroid altogether, with a topical calcineurin inhibitor (see below). Studies have suggested that topical calcineurin inhibitors can be applied three times weekly to recurrently affected sites to retain control of the dermatitis once improved with the use of topical steroids.102,103

The potency of a topical corticosteroid is largely determined by vasoconstrictor assay, and is related to its vehicle as well as to its chemical formulation. Vasoconstrictor assays reveal that generic formulations tend to vary in their clinical activity and their vehicles may at times contain agents differing from those of brand name formulations. Thus, care must be taken in considering substitution of brand name corticosteroids by generic formulations. The concentration of each topical corticosteroid is only significant with respect to potency relative to other corticosteroids of the same chemical formulation. Accordingly, hydrocortisone acetate 2.5% is much weaker than triamcinolone acetonide 0.1%, which in turn is weaker than clobetasol propionate 0.05%, even though the concentrations would suggest the opposite. It also should be recognized that hydrocortisone acetate differs chemically from hydrocortisone butyrate, hydrocortisone probutate, and hydrocortisone valerate, which as mid-potency steroids are stronger than hydrocortisone acetate. Halogenated steroids are usually stronger than non-halogenated steroids.

Corticosteroid ointments afford the advantage of occlusion, more effective penetration, and in general greater efficacy than equivalent cream or lotion formulations. Ointments are particularly effective in the management of dry, lichenified, or plaque-like areas of dermatitis. Ointment formulations, however, may occlude eccrine ducts, inducing sweat retention and pruritus, and hair follicles, leading to folliculitis. As with emollients, formulations in ointments may not be as well tolerated during the summer months of increased heat, perspiration, and high humidity. On the other hand, creams often contain additives that may be irritating or sensitizing. Creams and lotions, however, are more cosmetically elegant, and afford the advantages of greater convenience and acceptability during hot weather and in intertriginous areas. Traditional gels and foams are not well tolerated in individuals with AD, but may be most effective in the management of acute weeping or vesicular lesions. Topical corticosteroids in emollient-based foam formulations and hydrocolloid gels (in contrast to the alcohol-containing foams and gels) are particularly useful for hairy areas, to avoid occlusion, and for cosmesis. Oil preparations are most commonly used for scalp dermatitis. Best applied to a wet scalp, oil formulations can be shampooed out after at least 1 hour to overnight. A fluocinolone acetonide oil preparation, however, has been shown to be helpful after the bath for children with extensive AD.104

Occlusion of treated areas with polyethylene film, such as Saran wrap, or the use of corticosteroid-impregnated polyethylene film (Cordran tape) enhances the penetration of corticosteroids up to 100-fold. This mode of therapy is particularly effective for short periods of time (8–12 h a day on successive days) for patients with chronic lichenified or recalcitrant plaques of dermatitic skin. Occlusive techniques, however, are contraindicated for prolonged periods of time, and are not recommended in infected or intertriginous areas. Given that the diaper is an occlusive dressing, application of steroids in the diaper area of infants should be avoided or limited to short-term use of low-strength topical steroids.

For sites of severely lichenified dermatitis, salicylic acid can be compounded into preparations with steroids to improve penetration. Tar (liquor carbonis detergens or crude coal tar) can be also be used as an adjunctive therapy in patients with chronic dermatitis in the form of tar baths (e.g., Cutar) or compounded with topical corticosteroids (e.g., compounding triamcinolone 0.1% with 6% salicyclic acid and 5–10% liquor carbonis detergens in Aquaphor ointment). The objectionable odor, staining properties, potential for irritation, risk of causing folliculitis, and low potential risk of later carcinogenesis make tar a choice only for only selected patients.

Where should you not use hydrocortisone cream?

Only use hydrocortisone skin treatments on children under 10 years old if a doctor recommends it. Creams you can buy are not supposed to be used on the eyes, around the bottom or genitals, or on broken or infected skin.

Is hydrocortisone valerate 0.2% strong?

This medication is used to treat a variety of skin conditions (such as eczema, dermatitis, allergies, rash). Hydrocortisone valerate reduces the swelling, itching, and redness that can occur in these types of conditions. This medication is a medium-strength corticosteroid.

How long does it take for hydrocortisone cream to start working?

Regardless of the strength, steroid creams “start working within 1 day,” says Corinna Bowser, MD. She's an allergist and immunologist with Suburban Allergy Consultants in the Philadelphia area. “We usually see a reduction of itchiness, redness and inflammation in 1 to 3 days.”

What does hydrocortisone cream do to the skin?

Hydrocortisone topical is used to treat redness, swelling, itching, and discomfort of various skin conditions. Hydrocortisone is in a class of medications called corticosteroids. It works by activating natural substances in the skin to reduce swelling, redness, and itching.
