Can erythromycin treat bronchitis?
Patient: Hi. My 3yr old son has possible bronchitis and is on erythromycin (6mls twice a day). He has had three doses so far. When he got undressed this evening i noticed a rash all over his hips, thighs and upper arms. It is raise and reddish shapes a bit like clouds formations, they are just outlines though. The centre of each marbled shape is not filled in. Is it an allergic reaction to the antibiotic? Thanks for your help. Doctor: Thanks for your question on Health Care Magic. I can understand your concern. Erythromycin is macrolide group of antibiotic. And it can cause allergic skin reaction. So his rashes can be due to erythromycin induced skin allergy. Another possibility is viral rashes. Viral infection also cause similar kind of rashes on skin. He is also having bronchitis and viral infection is most common cause for bronchitis. So viral infection can be the cause for bronchitis and skin rashes. So better to consult dermatologist and get done clinical examination of rashes. Also discuss about possibility of viral infection and erythromycin related rashes.. Hope I have solved your query. Wishing good health to your son. Thanks.
