Steroid creams reduce inflammation in conditions like eczema and dermatitis. They work well, and two opposite mistakes are common: using a strong one for too long in the wrong place, and being so worried about them that the condition is undertreated.

They come in a range of strengths, from mild through to very potent, and advice about one does not transfer to another. A mild cream used briefly on a small area is a very different proposition from a potent one used for weeks. Know which you have.

Common side effects of this pharmacy medicine or category

These come from prolonged or inappropriate use, not from a short course as directed. Fear of them leads some people to use too little for too short a time, leaving the condition flaring, which brings its own problems including skin infection and poor sleep. Using an adequate amount for the period advised, then stopping, is the intended pattern.

Interactions and duplicate-ingredient risks

Do not use a steroid cream on an undiagnosed rash, and in particular not on anything that might be a fungal or bacterial infection. Steroids reduce inflammation without treating infection, so the rash may look better briefly while the infection spreads. Ringworm treated with a steroid cream is a classic example of a rash that changes appearance and becomes harder to diagnose.

Some products combine a steroid with an antifungal or antibacterial for exactly this reason, but they are chosen deliberately rather than assumed.

If you also take steroid tablets, or use a steroid inhaler, mention the cream, since the total matters when large areas are treated. See long-term steroid side effects.

Warning signs and overdose concerns

Stop and seek advice for skin becoming thin, shiny or fragile; a rash that spreads or worsens despite treatment; signs of infection such as increasing pain, warmth, swelling, pus or crusting; or a rash that keeps returning as soon as you stop.

Get emergency help for difficulty breathing or swelling of the face, lips or throat.

With eczema that flares immediately every time treatment stops, the answer is usually a proper management plan including moisturisers rather than either continuous steroid use or abrupt stopping.
