Dd told me recently that she can always tell the difference between Calpol and Calprofen because the Calprofen makes her throat feel tingly. It’s the same if I use another brand too so I think it’s the ibuprofen that is doing it. Is this in fact a very mild allergic reaction? I usually use Calpol but have ibuprofen too but it’s suddenly occurred to me that if she reacts to it maybe I should make it known on her records? I am allergic to penicillin and I know that I once had a very bad reaction and was told it could be fatal if it happened again. Can a reaction go from very mild to serious?
