Can boiling water be used when preparing Lemsip sachets?
Lemsip packaging includes directions for hot water only due to potential risk of scalding when using boiling water to mix with the contents of the sachets. This is because Lemsip sachet contents are effervescent and the volume of water may increase rapidly, leading to possible spillage of the product. Efficacy is not altered by adding boiling water to the sachet’s contents.
