Alcoholism
Major:
Acephen
The acetaminophen in Acephen 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:
Acephen
The acetaminophen in Acephen 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.
Gastrointestinal Hemorrhage
Major:
Zantac
The raNITIdine in Zantac has a major potential interaction with Gastrointestinal Hemorrhage.
Histamine H2 receptor antagonists should not be used in the presence of vomit with blood, or bloody or black stools. These might be serious conditions and the diagnosis needs to be ruled out.
Hemodialysis
Moderate:
Zantac
The raNITIdine in Zantac has a moderate potential interaction with Hemodialysis.
Ranitidine is partially removed by hemodialysis and should be administered after dialysis.
Liver Disease
Major:
Acephen
The acetaminophen in Acephen 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:
Zantac
The raNITIdine in Zantac has a moderate potential interaction with Liver Disease.
Ranitidine is partially metabolized by the liver. Although dosage reductions are generally not necessary, therapy with ranitidine should be administered cautiously in patients with liver disease. Elevated ALT (SGPT) has been observed in patients receiving ranitidine intravenously at dosages greater than those normally recommended for 5 days or more.
Malnourishment
Major:
Acephen
The acetaminophen in Acephen 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. 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.
Phenylketonuria
Moderate:
Acephen
The acetaminophen in Acephen 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).
Moderate:
Zantac
The raNITIdine in Zantac has a moderate potential interaction with Phenylketonuria.
Zantac (brand of ranitidine) 150 EFFERdose tablets and granules both contain 16.84 mg of phenylalanine per each 150 mg of ranitidine. The phenylalanine content should be considered when these products are used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics).
Porphyria
Major:
Zantac
The raNITIdine in Zantac has a major potential interaction with Porphyria.
Ranitidine may rarely precipitate acute porphyria attacks and should be avoided in patients with a history of acute porphyria.
Renal Dysfunction
Moderate:
Zantac
The raNITIdine in Zantac has a moderate potential interaction with Renal Dysfunction.
Ranitidine is primarily eliminated by the kidney. Although the drug is generally well-tolerated, the daily dosage should initially be reduced in patients with moderate to severe renal impairment (CrCl < 50 mL/min). If necessary, the daily dosage may be increased with caution.
