Do you have data on the number of prescriptions and what proportion (%) of prescriptions in England are repeats both prescribed and dispensed for Ketoconazole 2% Shampoo in the last 2 years. Do you have the same data for Nizoral 2% Shampoo? Please could you also inform me what proportion of all prescriptions for both Ketoconazole 2% Shampoo and Nizoral 2% Shampoo are free prescriptions and what proportion of prescriptions are switches to and from a Coal Tar shampoos?

By “in the last 2 years” do you mean the latest 24 months of available data, the latest 2 complete calendar years or the latest 2 complete financial years? 2 years of available data 3.

Can you please confirm which drugs should be included in the category Ketoconazole and which should be included in the category Nizoral? Ketoconazole - Ketoconazole Shampoo 2% Nizoral – Nizoral Shampoo 2%, Nizoral Anti-dandruff shampoo 2%, Nizoral dandruff shampoo 2% 5. Could you please clarify what is meant by ‘“and what proportion of prescriptions are switches to and from a Coal Tar shampoos?” as we do not understand this part of your request. We want to understand how many of the prescriptions which are now for Nizoral or Ketoconazole have switched from Coal Tar 2% Shampoo, therefore to understand how much active switching is taking place. 6. Finally, please note that information on repeat prescribing is only available on electronic prescription forms. Electronic forms represent approximately 65% of our prescription data. If these shampoos were repeat prescribed on paper, such information would go unreported in our data and the lack of a complete dataset may skew your results. Does this information change how you’d like to proceed? No
