An adult woman takes two regular-strength tablets every four to six hours while symptoms last, as recommended by Tylenol. A total of 10 regular-strength tablets is the maximum that is safe to take within a 24-hour period.
Acetaminophen, the generic name for Tylenol, treats pain, fever, and pain symptoms related to a cold or the flu, states Tylenol. This drug is safe and effective when users follow proper dosage guidelines. However, people with liver disease or who regularly consume alcohol must use this drug with caution. Take pain medication at the first sign of pain or discomfort in order for it to work effectively, according to WebMD.
