Letter Re: Dental Preparedness

In "Dental Preparedness, by Pat" the author mentions "using 400mg of Ibuprofen taken with 800mg of Tylenol at the same time, every 4-6 hours." That could result in taking 4,800mg of Tylenol in a day. Online resources state the maximum safe dose is 4,000mg per day, or liver failure could result. [JWR Adds: Thanks for pointing that out! Clearly, at that dosage, that course of treatment must either end or the dosage be reduced after just18 hours.] – SunDog
