Hello,

Thank you for choosing DoctorSpring.

I assume that you are an otherwise healthy individual with no medication allergies and a normal body weight.
In that case the dose will be :

Oral double-strength tablet (Bactrim DS or Seprta DS) – 160 mg TMP (Trimethoprim) /800 mg SMX (sulfamethoxazole)
-- to be taken twice a day.

(Or two single strength tablets 80mg TMP / 400mg SMX twice a day).

Drink Plenty of water.

Hope this helps
Feel free to ask follow ups
