For a healthy adult, the generally recommended maximum daily dose of acetaminophen depends on whether you follow the FDA guidelines or the manufacturer's more conservative safety guidelines:
* **The FDA maximum limit:** **4,000 milligrams (mg)** in a 24-hour period.
* **The Manufacturer recommendation (e.g., Tylenol):** **3,000 milligrams (mg)** in a 24-hour period. The makers of Tylenol lowered their recommended maximum daily dose for over-the-counter use to help reduce the risk of accidental liver damage.
**Here is what that looks like in practical terms:**
* **Extra Strength (500 mg per pill):** The maximum is **6 pills** in 24 hours (3,000 mg).
* **Regular Strength (325 mg per pill):** The maximum is **10 pills** in 24 hours (3,250 mg).
**Crucial Safety Warnings:**
* **Check other medications:** Acetaminophen is widely used in combination with other drugs, especially cold, flu, allergy, and prescription pain medications (like NyQuil, DayQuil, Excedrin, or Percocet). You must count the acetaminophen in *all* medications toward your 24-hour total to avoid a fatal overdose.
* **Watch the clock:** You should not take more than the recommended dose at one time (usually 1,000 mg, or two Extra Strength pills) and you should wait at least 4 to 6 hours between doses.
* **Alcohol:** If you consume three or more alcoholic drinks a day, your liver is more susceptible to damage. You should consult a doctor before taking acetaminophen, and your safe maximum dose will be significantly lower.
* **Liver conditions:** If you have any pre-existing liver disease, you should not take acetaminophen without a doctor's explicit approval.
