Brief Summary:
Sinus surgery is a common, day surgery procedure performed by general and subspecialty trained otolaryngologists. In most cases, this is a safe surgery with a low incidence of complications. When there is significant bleeding or enough bleeding to obscure important anatomical landmarks, there is a higher chance of complications. These complications can include blindness, meningitis or cerebrospinal fluid leak. Our hypothesis is that in patients taking oral tranexamic acid three days before surgery and six days after, there will be less intraoperative bleeding, better surgical visualization and less postoperative bleeding events.

Oral form, 100mg, tid (three times per day), 3 days before/the day of/6 days after the surgery
Other Name: Cyclokapron
Placebo Comparator: A
This will be the control group which will take the placebo medication for 3 days before and six days after their functional endoscopic sinus surgery (FESS).
Drug: Placebo
Placebo, Oral form, three times a day, 3 days before/day of/6 days after surgery

Primary Outcome Measures :
  1. Intraoperative bleeding amount [ Time Frame: During the surgery ]

Secondary Outcome Measures :
  1. Surgical visualization scoring [ Time Frame: During the surgery ]
  2. Postoperative bleeding events [ Time Frame: Six days after the surgery ]
