Do not administer during chronic treatment with drugs that can determine the induction of the hepatic monooxygenase or in case of exposure to substances that can have this effect (see section 4.5). Paracetamol should be used with caution in patients with renal insufficiency (creatinine clearance ≤ 30 ml / min). Use with caution in cases of chronic alcoholism, excessive intake of alcohol (3 or more alcoholic drinks per day), anorexia, bulimia, or cachexia, chronic malnutrition (low reserves of hepatic glutathione), dehydration, hypovolemia.
