Hello,
Thank you for asking the query.

To treat Gonorrhoea Amoxicillin is taken in 3gram one time dosage. So you might need to take 3 capsules of 875mg Amox( or if you can 500mg – 6 capsules ). The combined dosage should be 3 gm. And it should be taken together, preferably with food.

But, please note Amoxicillin will work only if it’s a Gonorrhoea. Moreover antibiotic resistance is common and Amoxicillin is no longer the preferred drug of choice. Ceftriaxone single dose injection or Azithromycin 2gm single oral doses are the preferred treatment options.

I recommend to get in touch with a Family Physician or STD specialist for further treatment.
Thank you
