Dd is constantly ill with ear infections and infected eczema. Dr gave her the above ( can't be bothered to spell it again) and she has developed a swollen blotchy face and rash all over her body. Saw dr again today and he has stopped that and put her on another one. Last dose of erythromycin 12.30 (midday) today surely rash should be getting better by now? Actually face looks worse.
