Abstract

Topical corticosteroids are very useful drugs in the treatment of various inflammatory and pigmentary dermatoses. However, they are susceptible to overuse and misuse by virtue of their anti-inflammatory and pigment-lightening properties. It is therefore important for all clinicians to keep in mind the ethical underpinnings of the basic tenets of topical corticosteroid use. Basic aspects of medical ethics like truth telling, patient autonomy, and non-malfeasance are discussed in the context of topical corticosteroid use, so that prescribers can be aware of the potential pitfalls that lie in their way. The broad clinical prerequisites of ethical topical corticosteroid use are also dealt with briefly.

Learning Points




  1. 1.


    A working clinical diagnosis and a thorough knowledge of clinical pharmacology of corticosteroid being prescribed are the two essentials of ethical use of TC.

     

  2. 2.


    Full explanation of the pros and cons of TC therapy should be done to the patient and all efforts should be made to ensure correct use. However, the patient’s wishes should be respected if he/she doesn’t want to use them.

     

  3. 3.


    “First do no harm” should be the guiding principle, especially if the disease in question is not a classical corticosteroid-responsive dermatosis or the use is for esthetic benefit.

     


5.1 Introduction


Topical corticosteroids (TCs) are some of the most extensively used therapeutic agents in the treatment of skin diseases. They are very widely prescribed not only by dermatologists but also general practitioners, pediatricians, gynecologists, and other specialists. They have antipruritic, anti-inflammatory, anti-proliferative, and pigment-lightening activity on the skin [1]. This wide-ranging activity profile leads to their frequent use in dermatology prescriptions. A recent prescription audit from an Indian dermatology clinic revealed that close to 30% of all prescriptions contained a TC [2]. A study from primary-care physicians in Bahrain reported that 13% of the prescriptions to infants contained one or more TC and almost half of them were moderately potent or potent [3]. In addition to prescription use, mild topical corticosteroids have over-the-counter status in most countries and are considered generally safe for unsupervised use. In India, although topical corticosteroids are Schedule H drugs and therefore can only be dispensed on the prescription of a registered medical practitioner, legal and enforcement loopholes allow an almost completely unregulated sale of topical agents containing corticosteroids.

An important reason for such widespread use is the ability of TCs to give relatively quick relief in most unpleasant signs and symptoms of skin diseases. Symptoms such as itch, stinging, and tenderness are rapidly relieved regardless of the underlying cause, as are redness, scaling, and hyperpigmentation. The transient nature of such improvement becomes quickly apparent upon discontinuation of treatment and can lead to a vicious cycle of abuse of TC to control worsening complaints that are only suppressed, not treated.

The increasing popularity of esthetic dermatology has also subtly led to a shift in physician and patient behavior where the former have simply become purveyors of various treatments designed to enhance appearance and the latter into demanding clients or consumers of such services. Patient satisfaction is a very important parameter in this scenario [4], which can lead to diminished importance being given to potential long-term adverse effects of treatments. The pigment-lightening activity of TC is especially pertinent in this scenario, with a lot of Indian clients demanding “fairness treatments” from their esthetic physicians, who advertise such services in contravention of medical ethics and law. This leads to widespread misuse of TC-containing products in the community [58]. Even apart from the esthetic dermatology setting, traditional dermatologists are facing increasingly demanding patients who are intolerant of unpleasant symptoms and expect instant gratification in medicine, as in modern life in general. This greatly increases the chances of unethical or irrational use of these agents. This misuse happens due to various errors of omission or commission by patients, pharmacists, and physicians themselves, as several studies have shown [58]. Both local and systemic side effects can occur due to such misuse of TC [6].

The extent of damage that is caused by the rampant abuse of TC can be gauged by a recent study of 1000 dermatology outpatients [9] where 51.9% of patients using these agents reported suffering from at least one side effect. In this study, acne was one of the most common reasons for use, an indication of the extent of irrational use of TC in the community. It is perhaps due to such misuse that TCs have acquired a bad reputation in the minds of lay persons, and a small but growing population of patients are becoming TC-phobic, eschewing their use even for legitimate indications [10, 11]. For these reasons, it is absolutely essential that clinicians reacquaint themselves with rational and ethical use of topical corticosteroids.


5.2 What Are the Ethical Issues That Are Relevant to Topical Corticosteroid Use?


Ethical issues in topical corticosteroid use are manifold. From the public health point of view as well as in individual patient-physician interaction, various ethical questions arise vis-à-vis TC use and need to be addressed:


  1. 1.


    Truth telling: Physicians often use TC for symptom relief when they are faced with an irate patient who has severe itching or redness of the skin of unclear etiology, without paying sufficient attention to diagnosing the illness and getting to the root of the problem. The reasons may be multiple, ranging from overcrowded OPDs to a natural human tendency to ease the pain of the patient. However, in most such situations, the patient is not aware that the physician has not been able to arrive at a firm diagnosis and is merely buying time by prescribing something that will give quick relief while planning investigations or a more detailed examination at a subsequent visit. The problem with such an approach is quite evident: the patient happily continues to use the TC for a long time, without bothering to return to the physician for another evaluation or investigations. If the physician honestly confesses to the patient that he is unable to arrive at a firm diagnosis and needs a revisit or investigations to do so, patients can become more amenable to tolerate their unpleasant symptoms while this is done. Quite a few prescriptions of TC can be avoided in this way, thereby minimizing the chances of misuse.

     

  2. 2.


    Patient autonomy: This refers to respect for the individuals’ right to make informed decisions about their personal matters. In other words, the patient has the right to refuse or choose their treatment (Voluntas aegroti suprema lex). In direct contrast to this is the concept of paternalistic medicine, where physicians simply order the patients to take a drug, without regard to his personal preferences, beliefs, etc. With regard to TCs, this law applies when we are faced with a steroid-phobic patient. In this situation, “soft paternalism” [12] is often a good approach whereby such a patient should be counselled about the potential benefits of TC use, the harm that can be caused by nonuse, and how common adverse effects can be avoided. However, they should also be informed about alternative therapies, e.g., topical calcineurin inhibitors or calcipotriol and their efficacy vis-à-vis TCs. After this, whatever their ultimate decision be, it should be respected and a prescription given accordingly.

     

  3. 3.


    Non-malfeasance: This is the principle of primum non nocere (first, do no harm). There are important ramifications of this principle in a TC prescription. A common scenario where non-malfeasance needs to be remembered is a patient who is obsessed with a fair complexion and asks for a TC prescription which he/she may have heard about from a friend. It is absolutely essential to avoid the temptation to give in to the patient’s request in this situation. This is especially true in esthetic practice, where healthcare providers are dealing with healthy clients, not sick patients. The desire to give the client what he/she wants can sometimes come into conflict with non-malfeasance in this situation. For example, TC are sometimes used to control redness or post-inflammatory hyperpigmentation caused by a chemical peel or laser resurfacing, which would perhaps not been done if the principle of non-malfeasance had been observed strictly. Non-malfeasance also becomes relevant when we are dealing with an undiagnosed rash and a demanding, distressed patient. Several studies have been reported on the misuse of TCs, especially on the face [6, 7] where the initial prescription was given for an undiagnosed facial rash which then led to prolonged misuse of TCs leading to considerable morbidity. In such a scenario, pending a diagnosis, TCs should be avoided and relief given with safer options like topical antipruritics and oral antihistamines. In the absence of a clear diagnosis and treatment plan, a physician should not hesitate to refer a patient to a senior colleague or an expert instead of using TCs to suppress unpleasant symptoms indefinitely.

     

  4. 4.


    Beneficence vs. autonomy: This kind of conflict occurs when patients disagree with recommendations that doctors believe are in the patients’ best interest. An appropriate example would be a patient with widespread eczema who is applying potent TCs over a large area leading to adverse effects [13]. The appropriate approach in such a situation would be to start a systemic steroid-sparing drug like azathioprine and gradually taper the TC. However, many patients are scared of systemic immunosuppressives and resist such treatment. Appropriate counselling about the dangers of potent TC use over large areas along with laboratory demonstration of adrenal suppression, low serum cortisol levels, etc. will be needed to convince the patient.

     

In fact, effective communication is the key to resolving almost all ethical dilemmas faced by a physician prescribing TCs. Not only doctor-patient but communication between doctors of different specialties and between doctors and society in general is essential in resolving these ethical issues. This is discussed in greater detail in later sections (vide infra).


5.3 Prerequisites for Ethical Use of Topical Corticosteroids [14]





  1. 1.


    The right diagnosis: There are relatively few conditions where there is good evidence of efficacy of TCs. Various eczemas, psoriasis, lichen planus, immunobullous diseases in their localized form, and skin manifestations of collagen vascular diseases like lupus erythematosus or dermatomyositis are the best-established indications. Other conditions where careful, short-term use may be warranted are superficial fungal or bacterial infections associated with significant inflammation, localized itch of any origin, and certain idiopathic diseases characterized by dermal inflammation, e.g., superficial variants of pyoderma gangrenosum. In the absence of a diagnosis, it is very important to avoid TC use so that conditions like tinea incognito and Majocchi’s granuloma are not produced [15]. If a patient is already applying TC, thereby obscuring the clinical features of a disease, an appropriate treatment-free interval should be given after explaining to the patient that his/her symptoms may flare up temporarily to facilitate a diagnosis.
