This page is about legal status only. A product being allowed doesn't mean it's right for your skin, and a product being banned doesn't tell you how risky an old bottle at home is. If you're worried about a reaction, speak to a pharmacist or GP. If you've used a cream you think contained mercury, speak to a GP.
