The maximum dose of tylenol that can be consumed safely over a 24 hour period is 4,000
mg. However, newer lower limits are coming out that states only 2,000-2,600
mg of tylenol should be ingested when taken daily over the long term. Additionally, one should not take more than 1,000 mg of tylenol per dose within a 4 hour period. The new limits state that a person should instead wait 6 hours before the next dose.
