ACETAMINOPHEN-CODEINE

Acetaminophen 300mg, Codeine Phosphate 30mg, Oral tablet

Alcohol

· Severity: Major

· Notes for Consumers: Avoid alcohol-containing drinks while taking this medicine. Using this drug along with alcohol can lead to serious side effects. You may feel drowsy or more tired when taking these drugs together. Do not drive or operate machinery until you know how this drug affects you, and especially if you are drinking alcohol-containing beverages. If you notice slurred speech, confusion, severe weakness, or difficulty breathing, contact your health care provider immediately.

· Notes for Professionals: Alcohol is associated with CNS depression. The combined use of alcohol and CNS depressants can lead to additive CNS depression, which could be dangerous in tasks requiring mental alertness and fatal in overdose. Alcohol taken with other CNS depressants can lead to additive respiratory depression, hypotension, profound sedation, or coma. Consider the patient's use of alcohol or illicit drugs when prescribing CNS depressant medications. In many cases, the patient should receive a lower dose of the CNS depressant initially if the patient is not likely to be compliant with avoiding alcohol.

Grapefruit juice

· Severity: Moderate

· Notes for Consumers: It is recommended that you limit and do not significantly alter your intake of grapefruit or grapefruit juice while taking codeine. Side effects from codeine may get worse if you increase your intake of grapefruit juice. Talk to your doctor first. Contact your doctor right away if you have symptoms of codeine side effects such as slurred speech, confusion, weakness, or trouble breathing. Do not drive or operate machinery until you know how codeine affects you.

· Notes for Professionals: Patients should not significantly alter their intake of grapefruit or grapefruit juice during therapy with codeine. Grapefruit juice, a CYP3A4 inhibitor, may increase plasma concentrations of codeine, a CYP3A4 substrate. This may increase or prolong codeine-related toxicities including respiratory depression. Advise patients accordingly; patient monitoring and dosage adjustments may be necessary if grapefruit is consumed 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.
