i was prescribed 500mg flucloxacillin 4x a day for a skin infection, i only ever took 1 tablet and had a bad reaction (tremors, pounding heart and swolen lips) my doctor gave me 1 x 10ml dose of loratidine to counter act the reaction and this seemed to do the trick, i have now been prescribed erythromycin for my skin infection, my question is, i read that loratadine and erythromycin shouldnt be mixed, so how long should i wait after having that single flucloxacillin tablet and then the 10ml dose of loratadine before i start to take my erythromycin
