I have antibiotics... not sure the brand/name But both are very strong
Just to be a twat - if you have antibiotics - are you sure you have ABX that will help with a dermal infection and not ABX that will sort your urine infection?!
There are 1st, 2nd and third line ABX. ABX which do different things (urine infections, upper urine infections, skin infections, chest infections - or you blast a broad spectrum ABX and run the risk of the shits and dehydration
These are my local prescribing guidelines I use at work - I hope you can access where you are - it'll give you some understanding on which to use for what infection...
