Delayed Reaction to Penicilin12/16/2010 |
Is it possible to have a delayed reaction of about three or four weeks to penicilin or clindamycin? Reaction was itchy rash which subsided after three days.
Delayed drug reactions do occur but usually days and not weeks after taking the drug.
3-4 weeks is not very likely.
It was probably related to some other process. However, without more history it is difficult to ascertain to what.
To be safe, I would recommend seeing a board certified allergist who has experience addressing drug reactions for further evaluation.
