## Primary Indications
* Pain relief (mild to moderate)
* Fever reduction
## Adult Dosing
* **Standard Dose:** 325 mg to 1000 mg every 4 to 6 hours as needed.
* **Maximum Daily Dose:** 4000 mg per 24 hours. Higher doses are generally not recommended due to increased risk of hepatotoxicity. Some protocols may allow up to 4000 mg, but caution is advised.
## Pediatric Dosing
Pediatric dosing is typically based on weight and age. The specific formulation and concentration of Mylot%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520at (e.g., liquid, chewable, suppositories) will dictate the volume or number of units to administer. Always refer to the product's labeling or a reliable pediatric dosing reference. A common pediatric dose is 10-15 mg/kg/dose every 4-6 hours.
## Dose Adjustments
* **Hepatic Impairment:** Use with caution and consider reduced doses. The maximum daily dose should not exceed 2000 mg in patients with severe hepatic impairment.
* **Renal Impairment:** Dose adjustments are generally not required for mild to moderate renal impairment. In severe renal impairment (CrCl < 10 mL/min), consider extending the dosing interval to every 8 hours.
## Contraindications
* Known hypersensitivity to acetaminophen.
* Severe hepatic impairment or severe active liver disease.
## Adverse Effects
* **Common:** Generally well-tolerated at therapeutic doses.
* **Serious:**
* **Hepatotoxicity:** The most serious adverse effect, especially with overdose or chronic high-dose use, or in combination with alcohol. Symptoms can include nausea, vomiting, abdominal pain, jaundice, and confusion.
* **Hypersensitivity reactions:** Rash, itching, hives, swelling.
* **Hematologic effects:** Thrombocytopenia, leukopenia, neutropenia (rare).
## Key Drug Interactions
* **Alcohol:** Chronic heavy alcohol consumption increases the risk of acetaminophen-induced hepatotoxicity. Avoid concurrent use or limit alcohol intake.
* **Warfarin:** Acetaminophen may increase the anticoagulant effect of warfarin. Monitor INR closely, especially with chronic or high-dose acetaminophen use.
* **Isoniazid, Phenytoin, Carbamazepine, Rifampin, and other CYP enzyme inducers:** These can increase the risk of hepatotoxicity by increasing the formation of toxic metabolites of acetaminophen.
* **Probenecid:** May increase the bioavailability of acetaminophen.
## Monitoring
* **Liver Function Tests (LFTs):** Consider baseline and periodic LFTs in patients with risk factors for liver disease or those on long-term, high-dose therapy.
* **Renal Function:** Monitor renal function in patients with pre-existing renal disease.
* **INR:** Monitor closely in patients taking warfarin.
## Clinical Pearls
* Acetaminophen is found in many over-the-counter and prescription combination products. Patients must be educated to avoid exceeding the maximum daily dose from all sources.
* The risk of hepatotoxicity is significantly increased when acetaminophen is taken with alcohol.
* In overdose situations, prompt initiation of N-acetylcysteine (NAC) is crucial for preventing or minimizing liver damage.
