Myths & Facts

Myth: Topical corticosteroids should not be used on cracked, broken or weepy skin.

Topical corticosteroids are effective in helping to heal cracked and broken eczematous skin. While these creams and ointments are more easily absorbed through eczematous skin, they are safe as long as they are used according to the advice of your physician and their use is tapered or discontinued when the skin is healed. If your skin is tender and swollen it may be infected; this should be evaluated by your doctor.

Myth: Topical corticosteroids cause stunted growth and development.

Corticosteroid creams and ointments should not be confused with anabolic steroids infamously used by some athletes. But, babies and very young children are at risk of absorbing topically applied corticosteroids into the bloodstream, especially when these medications are very potent, applied in large quantities too frequently, or used inappropriately under a diaper or other covered (occluded) area. As such there may be a risk of slowing growth (height). Corticosteroids taken by mouth or used for prolonged periods of time are absorbed into the bloodstream. These can reduce the body’s production of natural corticosteroids, weaken immune responses and affect growth, but do not affect brain development. Topically applied corticosteroids used in the appropriate quantity and for the appropriate duration are unlikely to affect growth or the body’s ability to fight infections.

It is important to follow the advice of your doctor when using topical corticosteroids in babies and young infants.

When making a decision about the need for topical corticosteroid therapy, it is critical to weigh the potential risks of the treatment against the risks of the disease. Untreated severe eczema can have an enormously negative impact on overall well-being, restful sleep, ability to concentrate and learn, and family dynamics, which can, in turn, impair a child’s normal growth and development. When topical corticosteroids are applied correctly, the risks of the disease are far greater than the risks of treatment.

Myth: Topical corticosteroids cause lightening or darkening of the skin.

Topical corticosteroids rarely cause skin discoloration, which resolves when the treatment is stopped. Skin discoloration is much more likely to result from the eczema itself, because skin inflammation can increase or decrease the amount of tan pigment in the skin. Skin discoloration from eczema will also resolve over time, but may take several months.

Myth: Topical corticosteroids promote excessive hair growth.

If topical corticosteroids are used for long periods, they can occasionally cause a temporary, mild increase in fine hair growth in the treated areas, although this is rare. Frequent scratching can also cause a temporary, mild increase in fine hair growth.

Myth: Topical corticosteroids will prolong the eczema and decrease the chances of improvement with age.

There is no evidence that topical corticosteroids change the underlying natural course of the disease.

Myth: A lot of moisturizer can eliminate the need for topical corticosteroids.

Proper bathing and moisturizing is essential in managing chronic eczema. Although moisturizers are a first-line treatment, when used alone they will only control the very mildest forms of eczema. Moderate or severe eczema cannot be treated effectively with moisturizers alone. Once the skin becomes red (inflamed), additional anti-inflammatory medication is needed to control the disease. Anti-inflammatory treatments include topical corticosteroids, topical calcineurin inhibitors (TCI’s such as Elidel or Protopic), ultraviolet light therapy, or systemic medications.

Myth: Topical corticosteroids should always be applied in smaller amounts than prescribed.

It is true that only a thin layer is needed, but it is important to apply enough to cover all the red areas. A useful way of knowing the correct amount to apply is the fingertip rule: Squeeze a ribbon of the topical corticosteroid onto the tip of an adult index finger, between the fingertip and the first finger crease. This amount of corticosteroid represents “one fingertip unit”, and should be enough to cover an area of skin the size of two flat adult palms of the hand (including fingers).

Topical Steroid Addiction/Red Skin Syndrome/Steroid-Induced Eczema.

Over the past few years, the National Eczema Association (NEA) has received an increasing number of patient inquiries regarding what has been termed Topical Steroid Addiction (TSA), also called Red Skin Syndrome (RSS) or Steroid-Induced Eczema.  Topical steroids are a very important therapy for eczema. It should be emphasized that what has been called TSA or RSS is quite uncommon, and in this uncommon situation topical corticosteroids are not appropriate treatment. A NEA Task Force has been formed to conduct in-depth review and create a NEA position on this topic to continue educating both medical professionals and eczema patients and caregivers.  The expected publication date is late 2014.
