The UK’s pharmaceutical industry manufactures thousands of different medicines in many different strengths and forms. It is a regulatory requirement that all medicines can be differentiated from one another enabling each medicine to be individually identifiable. One of the ways the industry achieves this is by adding colour to the tablets or capsules. We also print or emboss letters and numbers on medicines, sometimes using multiple methods. The colours and dyes used within the formulation of Teva’s medications are approved by the Medicines & Healthcare products Regulatory Agency (MHRA).
