Drug interactions
Moderate drug interactions
Moderate:
fenofibrate insulin isophane (NPH)
Applies to: fenofibrate and Humulin N Pen (insulin isophane)
Using fenofibrate together with insulin isophane (NPH) may increase the risk of hypoglycemia, or low blood sugar. Symptoms of hypoglycemia include headache, dizziness, drowsiness, nervousness, confusion, tremor, nausea, hunger, weakness, perspiration, palpitation, and rapid heartbeat. Talk to your doctor if you have any questions or concerns. You may need a dose adjustment or more frequent monitoring of your blood sugar to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
insulin isophane (NPH) Food/Lifestyle
Applies to: Humulin N Pen (insulin isophane)
Alcohol may affect blood glucose levels in patients with diabetes. Both hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) may occur, depending on how much and how often you drink. You should avoid using alcohol if your diabetes is not well controlled or if you have high triglycerides, neuropathy (nerve damage), or pancreatitis. Moderate alcohol consumption generally does not affect blood glucose levels if your diabetes is under control. However, it may be best to limit alcohol intake to one drink daily for women and two drinks daily for men (1 drink = 5 oz wine, 12 oz beer, or 1.5 oz distilled spirits) in conjunction with your normal meal plan. Avoid drinking alcohol on an empty stomach or following exercise, as it may increase the risk of hypoglycemia. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Disease interactions
15 potential interactions Applies to: 13 conditions, including Hypokalemia, Anemia, Primary Biliary Cholangitis, Gallbladder Disease, and Adrenal Insufficiency.
Adrenal Insufficiency
Moderate:
Humulin N Pen
The insulin isophane (NPH) in Humulin N Pen has a moderate potential interaction with Adrenal Insufficiency.
Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.
Anemia
Moderate:
fenofibrate
Fenofibrate has a moderate potential interaction with Anemia.
Mild to moderate hemoglobin, hematocrit and white blood cell decreases have been observed in patients following initiation of fibric acid derivatives therapy. However, these levels stabilize during long-term administration. Thrombocytopenia and agranulocytosis have been reported in individuals treated with these agents. Caution is recommended when treating patients predisposed to hematologic changes. Periodic monitoring of red and white blood cell counts is recommended during the first 12 months of therapy.
Anorexia/Feeding Problems
Moderate:
Humulin N Pen
The insulin isophane (NPH) in Humulin N Pen has a moderate potential interaction with Anorexia/Feeding Problems.
Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.
Autonomic Neuropathy
Moderate:
Humulin N Pen
The insulin isophane (NPH) in Humulin N Pen has a moderate potential interaction with Autonomic Neuropathy.
Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.
Gallbladder Disease
Major:
fenofibrate
Fenofibrate has a major potential interaction with Gallbladder Disease.
The use of fibric acid derivatives is contraindicated in patients with gallbladder disease. A significantly increased incidence of cholelithiasis has been observed in patients treated with the fibric acid derivative, clofibrate, presumably because of increased cholesterol excretion into the bile. Based on two separate studies (the WHO study and the Coronary Drug Project study), clofibrate use was associated with twice the risk of developing cholelithiasis and cholecystitis requiring surgery. Due to their structural and pharmacologic similarities, use of other fibric acid derivatives may be expected to carry the same risk.
Hypokalemia
Moderate:
Humulin N Pen
The insulin isophane (NPH) in Humulin N Pen has a moderate potential interaction with Hypokalemia.
Hypokalemia may commonly occur during treatment with insulin. Use with caution in patients who may be particularly at risk of developing hypokalemia (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations).
Liver Disease
Major:
fenofibrate
Fenofibrate has a major potential interaction with Liver Disease.
The use of fibric acid derivatives is contraindicated in patients with active liver disease or unexplained, persistent elevations of serum transaminases. Fibric acid derivatives therapy is associated with dose-related hepatotoxicity, including biochemical abnormalities of liver function, hepatitis (hepatocellular, chronic active, as well as cholestatic) and, rarely, cirrhosis. Postmarketing cases of severe drug-induced liver injury, including liver transplantation and death, have been reported. Therapy with these agents should be administered cautiously in patients with a history of liver disease and/or heavy alcohol use. Liver function tests, including serum transaminase levels and total bilirubin, should be performed at baseline and periodically throughout the duration of therapy. Therapy should be discontinued if signs or symptoms of liver injury develop or if elevated enzyme levels persist (ALT or AST greater than 3 times the upper limit of normal, or if accompanied by elevation of bilirubin). Do not restart therapy if there is no alternative explanation for the liver injury.
Moderate:
Humulin N Pen
The insulin isophane (NPH) in Humulin N Pen has a moderate potential interaction with Liver Disease.
Insulin requirements may be diminished in patients with renal or hepatic impairment due to reduced insulin metabolism and, in the latter case, also to reduced capacity for gluconeogenesis. Lower initial dosages may be appropriate, with careful monitoring of plasma glucose levels and dosing adjustments.
Malnourishment
Moderate:
Humulin N Pen
The insulin isophane (NPH) in Humulin N Pen has a moderate potential interaction with Malnourishment.
Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.
Myoneural Disorder
Major:
fenofibrate
Fenofibrate has a major potential interaction with Myoneural Disorder.
Severe myopathy, including rhabdomyolysis with acute renal failure secondary to myoglobinuria, has been reported rarely with the use of fibric acid derivatives. The myopathy may be dose-related and is characterized by muscle aches and/or weakness in conjunction with increases in creatine phosphokinase (CPK) values exceeding 10 times the upper limit of normal. Therapy with fibric acid derivatives should be administered cautiously in patients with preexisting myopathy or a myoneural disorder, since it may delay the recognition or confound the diagnosis of a drug-induced musculoskeletal effect. Patients should be advised to report promptly any unusual muscle pain, tenderness or weakness, particularly if accompanied by malaise or fever. Periodic CPK determinations may be considered in some patients, although the value of such monitoring is uncertain. Therapy should be withdrawn if markedly elevated CPK levels occur or if drug-related myopathy is diagnosed or suspected.
Myopathy
Major:
fenofibrate
Fenofibrate has a major potential interaction with Myopathy.
Severe myopathy, including rhabdomyolysis with acute renal failure secondary to myoglobinuria, has been reported rarely with the use of fibric acid derivatives. The myopathy may be dose-related and is characterized by muscle aches and/or weakness in conjunction with increases in creatine phosphokinase (CPK) values exceeding 10 times the upper limit of normal. Therapy with fibric acid derivatives should be administered cautiously in patients with preexisting myopathy or a myoneural disorder, since it may delay the recognition or confound the diagnosis of a drug-induced musculoskeletal effect. Patients should be advised to report promptly any unusual muscle pain, tenderness or weakness, particularly if accompanied by malaise or fever. Periodic CPK determinations may be considered in some patients, although the value of such monitoring is uncertain. Therapy should be withdrawn if markedly elevated CPK levels occur or if drug-related myopathy is diagnosed or suspected.
Panhypopituitarism
Moderate:
Humulin N Pen
The insulin isophane (NPH) in Humulin N Pen has a moderate potential interaction with Panhypopituitarism.
Hypoglycemia may commonly occur during treatment with insulin and/or oral hypoglycemic agents. Care should be taken in patients who may be particularly susceptible to the development of hypoglycemic episodes during the use of these drugs, including those who are debilitated or malnourished, those with defective counterregulatory mechanisms (e.g., autonomic neuropathy and adrenal or pituitary insufficiency), and those receiving beta-adrenergic blocking agents.
Primary Biliary Cholangitis
Major:
fenofibrate
Fenofibrate has a major potential interaction with Primary Biliary Cholangitis.
The use of fibric acid derivatives is contraindicated in patients with primary biliary cirrhosis. These agents may further raise the already elevated cholesterol in these patients.
Renal Dysfunction
Major:
fenofibrate
Fenofibrate has a major potential interaction with Renal Dysfunction.
The use of fibric acid derivatives is contraindicated in patients with significantly impaired renal function. The rate of clearance of fenofibric acid has been shown to decrease substantially when CrCl is below 50 mL/min, with drug accumulation during chronic dosing. Increased adverse effects, including rhabdomyolysis (with or without secondary renal failure) and severe hyperkalemia, have been associated with the use of fibric acid derivatives in patients with renal insufficiency. Therapy with these agents should be administered cautiously in patients with mild or moderate renal impairment. Close clinical monitoring is recommended during therapy.
Moderate:
Humulin N Pen
The insulin isophane (NPH) in Humulin N Pen has a moderate potential interaction with Renal Dysfunction.
Insulin requirements may be diminished in patients with renal or hepatic impairment due to reduced insulin metabolism and, in the latter case, also to reduced capacity for gluconeogenesis. Lower initial dosages may be appropriate, with careful monitoring of plasma glucose levels and dosing adjustments.
