ASDA has become the first supermarket in UK to produce and sell its own-brand malaria tablets’ Atovaquone/Proguanil’. Available at Asda pharmacies, the drug is priced at GBP 12 for 12 tablets and will cost 50% less as compared with other pharmacies. Shoppers can purchase the drug without prescription but need to complete a questionnaire. The drugs patent by GlaxoSmithKline expired in 2013.
