Yes, you can start flucloxacillin 500 mg capsules 3 times a day till you get evaluated as soon as the doctor’s clinic opens up.
Peri-anal abscesses are commonly due to gram positive bugs which are sensitive to flucloxacillin.
But get evaluated as sometimes they can be due to resistant bugs and many require drainage
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Please ask for any clarifications before closing and rating this query.
