Alcohol

· Severity: Major

· Notes for Consumers: Patients who drink more than 3 alcoholic drinks a day and take Acetaminophen are at increased risk of developing liver side effects. Limit alcohol intake while taking Acetaminophen. Avoid alcoholic drinks if you are taking Acetaminophen on a regular basis.

· Notes for Professionals: The risk of developing hepatotoxicity from acetaminophen appears to be increased in patients who regularly consume ethanol. Patients who drink more than 3 alcoholic drinks a day and take acetaminophen are at increased risk of developing hepatotoxicity. Acute or chronic ethanol use increases acetaminophen-induced hepatotoxicity by inducing cytochrome P450 CYP 2E1 leading to increased formation of the hepatotoxic metabolite of acetaminophen. Also, chronic alcohol use can deplete liver glutathione stores. Administration of acetaminophen should be limited or avoided altogether in patients with alcoholism or patients who consume ethanol regularly.

Tobacco

· Severity: Moderate

· Notes for Consumers: If you are a tobacco smoker, use of Acetaminophen can increase the risk of liver side effects. Immediately tell your doctor if you get severe abdominal pain, nausea, vomiting, or yellowing of the skin. Do not exceed 4 g acetaminophen/day in adults. Tell your doctor if Acetaminophen does not help your headache or other pain. Tobacco smoke may reduce the effectiveness of Acetaminophen.

· Notes for Professionals: Tobacco smoking induces the cytochrome P450 isoenzyme CYP1A2 and may potentially increase the risk for acetaminophen-induced hepatotoxicity during overdose via enhanced generation of acetaminophen's hepatotoxic metabolite, NAPQI. In one study, current tobacco smoking was found to be very frequent in patients admitted with acetaminophen poisoning. Tobacco smoking appears to be an independent risk factor of severe hepatotoxicity, acute liver failure and death following acetaminophen overdose.

Caffeine-containing Foods/Beverages

· Severity: Moderate

· Notes for Consumers: While taking Caffeine-containing medicines, limit the use of foods, beverages (examples: coffee, tea, colas), herbs (examples: guarana, green tea) and other products that contain additional caffeine, such as chocolate and some non-prescription medications or dietary supplements for headache, insomnia, or weight loss. Too much Caffeine can cause effects like nausea, nervousness, or sleeplessness. Some drug products for adults that contain caffeine have about as much caffeine as a cup of coffee.

· Notes for Professionals: Certain foods that contain high amounts of caffeine or theobromine should be limited during the therapeutic use of caffeine in order to limit additive methylxanthine effects. While taking Caffeine-containing medicines, limit the use of foods, beverages (examples: coffee, tea, colas), herbs (examples: guarana, green tea) and other products that contain additional caffeine, such as chocolate and some non-prescription medications or dietary supplements for headache, insomnia, or weight loss. Too much Caffeine can cause effects like nausea, nervousness, or sleeplessness. Some drug products for adults that contain caffeine have about as much caffeine as a cup of coffee.

Grapefruit juice

· Severity: Mild

· Notes for Consumers: Do not significantly alter your grapefruit juice intake while taking medicines containing caffeine. Some reports suggest that intake of grapefruit juice can increase side effects from caffeine. Too much Caffeine can cause effects like nausea, tremor, nervousness, or sleeplessness. If these occur, consider ingesting less caffeine daily.

· Notes for Professionals: Data are limited and conflicting as to whether grapefruit juice significantly alters the serum concentrations and/or AUC of caffeine. Caffeine is primarily a CYP1A2 substrate, and grapefruit juice appears to have but a small effect on this enzyme in vivo. One report suggests that grapefruit juice decreases caffeine elimination by inhibition of flavin-containing monooxygenase, a P450 independent system. This interaction might increase caffeine levels and mildly potentiate the clinical effects and common side effects of caffeine. If side effects appear, patients may need to limit either caffeine or grapefruit juice intake.
