Tylenol is safe before or after any surgery that you have. You should limit your daily dose of Tylenol or Acetamenophen to less than 4000mg per 24 hour period. Other typical non-steriodal medications such as Aspirin, Motrin, Alleve, Ibuprofen, etc. can make you bleed after surgery and should not be taken for at least 7-10 days prior to surgery.
Tylenol is safe to be take before surgery. Aspirin and other "non-steroidal anti-inflammatory" pain killers are not because they increase your risk of bleeding and bruising. Sincerely, Martin Jugenburg, MD
