How long can I use it for?
Seven days as a rule, and not beyond fourteen without being reviewed. This is the most important thing on the page. Flexural skin is thin, absorbs steroid readily, and thins permanently with prolonged use.
Can I use it on my face?
Better not to. Facial skin is the thinnest on the body and shows steroid damage soonest. Steroids also worsen acne and rosacea, and steroid-induced rosacea is difficult to treat afterwards. Ask before using it above the neck.
Why three ingredients in one cream?
Because inflamed skin in a warm moist fold commonly has both yeast and bacteria in it, and treating one without the other frequently fails. The steroid settles the inflammation while the other two deal with what is growing there.
Can I keep it for next time?
Not as a plan. Reaching for a leftover combination steroid cream for any new rash is how people end up treating something viral, or something that was never infected, with a potent product. If it keeps happening, the question is why — and that usually has a better answer than another tube.
Will it help my thrush?
For candidal skin infection in a fold, yes. For vaginal thrush, no — that needs a proper intravaginal antifungal or an oral tablet, and this is not the right product.
The rash got worse. What now?
Stop and seek advice. A rash worsening on treatment suggests allergy to one of the ingredients, a viral cause the steroid is feeding, or a diagnosis that was wrong. None of those improve with more cream.
