Consider adding:

• Erythroped A 500mg tablets (0501050H0BDAIAE)
• Erythroped Forte SF 500mg/5ml oral suspension (0501050H0BDAPAN)
• Erythroped PI SF 125mg/5ml oral suspension (0501050H0BDANAL)
• Erythroped SF 250mg/5ml oral suspension (0501050H0BDAMAM)

There's limited prescribing of these items (in most cases none), and none of them are listed in EMC, so I think they're unlikely to be very important. But probably still makes sense to add for completeness, and consistency in approach.

On the other hand, if the preference is to exclude products where there is no prescribing and they're not listed in EMC, then there's probably a few other items we could remove from the codelist such as:

• Rommix 250 EC tablets (0501050C0BIAAAB)

Otherwise, all looks good to me. @chrisjwood16

@a-d-brown Not sure what happened there. They should have been included - updated version here:

@chrisjwood16 - checked, all correct.
