Background first … will try to explain any chemical names/ medical terms/ acronyms in square brackets.
My mother and I both have a topical sensitivity – irritant not allergy – to anionic surfactants [foaming detergents in many household/ personal hygiene products]. Shampoo – in my case just bubbles – is a major trigger for atopic eczema, aqueous cream [1% Sodium Lauryl Sulphate] worsens contact dermatitis.
According to the patient information leaflet there is SLS in celecoxib [anti inflammatory] which I was prescribed six weeks ago. And in lansoprazole [reduces stomach acid] which I have not taken regularly in a year and a half.
