I've just been back to the Nurse concerning the hole in my leg. The nice lady (who remembered me) gave me some free bandages, a sheet of silver for the wound and a prescription for antibiotics. She cheerfully informed me that there are likely to be stomach-related side-effects. So of course I Wikipediad the drug and was informed:
Common adverse drug reactions (ADRs) associated with the use of flucloxacillin include: diarrhoea, nausea, rash, urticaria, pain and inflammation at injection site, superinfection (including candidiasis), allergy, and transient increases in liver enzymes and bilirubin.
Something to look forward to over the next few days then!
