You have taken the dose of amoxicillin
wrongly as it should be taken as 500 mg three to four times a day.
Now you have been prescribed ampilox.you must take at least 2 capsules three times a day for one week at least.
Locally you may apply erythromycin
ointment or CLINDAMYCIN
If the disease is hidradenitis suppurativa
,then the ideal antibiotics for treatment are rifampicin and CLINDAMYCIN orally.
