Disease interactions

7 potential interactions Applies to: 6 conditions, including Liver Disease, Dehydration, Alcoholism, Infectious Gastroenteritis, and Malnourishment.

Alcoholism

Major:

Panamax

The acetaminophen in Panamax has a major potential interaction with Alcoholism.

Chronic alcohol abusers may be at increased risk of hepatotoxicity during treatment with acetaminophen (APAP). Severe liver injury, including cases of acute liver failure resulting in liver transplant and death, has been reported in patients using acetaminophen. Therapy with acetaminophen should be administered cautiously, if at all, in patients who consume three or more alcoholic drinks a day. In general, patients should avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure. They should also be advised to seek medical attention if they experience signs and symptoms of liver injury such as fever, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, and jaundice.

Dehydration

Major:

Panamax

The acetaminophen in Panamax has a major potential interaction with Dehydration.

Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease. Patients with hepatic impairment may be at increased risk of toxicity. Severe liver injury, including cases of acute liver failure and death, have been reported in patients using this drug. Clinical monitoring of hepatic function is recommended. Caution is advised if using acetaminophen in patients with chronic malnutrition or severe hypovolemia. Instruct patients to avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure.

Infectious Gastroenteritis

Major:

avacopan

Avacopan has a major potential interaction with Infectious Gastroenteritis.

Patients with active, serious infections, including localized infections, should avoid the use of avacopan. It is recommended to consider the risks and benefits before using this drug in patients with chronic or recurrent infection, those who have been exposed to tuberculosis, a history of a serious or an opportunistic infection, have resided or traveled in areas of endemic tuberculosis or endemic mycoses; or have underlying conditions which can predispose them to infection. Monitor closely for developing signs and symptoms of infections during and after treatment and, if appropriate, treat accordingly. Treatment interruption should be considered if serious or opportunistic infections develop.

Liver Disease

Major:

Panamax

The acetaminophen in Panamax has a major potential interaction with Liver Disease.

Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease. Patients with hepatic impairment may be at increased risk of toxicity. Severe liver injury, including cases of acute liver failure and death, have been reported in patients using this drug. Clinical monitoring of hepatic function is recommended. Caution is advised if using acetaminophen in patients with chronic malnutrition or severe hypovolemia. Instruct patients to avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure.

Moderate:

avacopan

Avacopan has a moderate potential interaction with Liver Disease.

Avacopan is not recommended in patients with active, untreated and/or uncontrolled chronic liver disease (e.g., chronic active hepatitis B, untreated hepatitis C, uncontrolled autoimmune hepatitis) and cirrhosis. It is recommended to obtain liver functions tests (serum ALT, AST, alkaline phosphatase, and total bilirubin) before treatment initiation, every 4 weeks for the first 6 months, and as clinically indicated. Promptly evaluate a patient receiving this drug if it presents with ALT or AST greater than 3 times the upper limit of normal (ULN) and consider withholding treatment temporarily as clinically indicated. Treatment should be discontinued until drug-induced liver injury is ruled out if a patient presents with ALT or AST 5 times the ULN, or develops transaminases greater than 3 times the ULN with elevation of bilirubin to greater than 2 times the ULN . Benefits and risks should be considered prior to administering this drug to patients with liver disease.

Malnourishment

Major:

Panamax

The acetaminophen in Panamax has a major potential interaction with Malnourishment.

Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease. Patients with hepatic impairment may be at increased risk of toxicity. Severe liver injury, including cases of acute liver failure and death, have been reported in patients using this drug. Clinical monitoring of hepatic function is recommended. Caution is advised if using acetaminophen in patients with chronic malnutrition or severe hypovolemia. Instruct patients to avoid drinking alcohol while taking acetaminophen-containing medications.

Phenylketonuria

Moderate:

Panamax

The acetaminophen in Panamax has a moderate potential interaction with Phenylketonuria.

Several oral acetaminophen and acetaminophen-combination products, particularly flavored chewable tablets, contain the artificial sweetener, aspartame (NutraSweet). Aspartame is converted to phenylalanine in the gastrointestinal tract following ingestion. Chewable and effervescent formulations of acetaminophen products may also contain phenylalanine. The aspartame/phenylalanine content should be considered when these products are used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics).
