Drug interactions
Moderate drug interactions
Moderate:
atenolol insulin isophane (NPH)
Applies to: atenolol and Humulin N (insulin isophane)
Atenolol may interfere with blood glucose control thus increasing or reducing the effectiveness of insulin isophane (NPH) and other diabetic medications. Beta-blockers such as atenolol may increase the risk, severity, and/or duration of hypoglycemia (low blood sugar) in patients receiving insulin isophane (NPH) and certain other antidiabetic medications. In addition, beta-blockers may mask some of the symptoms of hypoglycemia such as tremor, palpitations and rapid heartbeat, making it more difficult to recognize an oncoming episode. Other symptoms of hypoglycemia such as headache, dizziness, drowsiness, nervousness, confusion, nausea, hunger, weakness, and perspiration are not affected. Hyperglycemia (elevated blood sugar levels) may also occur with some beta-blockers. You may need a dose adjustment of your diabetic medications during and after treatment with atenolol. You may also need to monitor your blood glucose levels more frequently, especially if you are prone to developing hypoglycemia. Talk to your doctor if you have any questions or concerns. 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:
atenolol Food/Lifestyle
Applies to: atenolol
You may take atenolol with or without food, but take it the same way every time. Avoid consumption of large amounts of orange juice to prevent any changes in your atenolol levels. Orange juice could decrease the effectiveness of atenolol.
Moderate:
insulin isophane (NPH) Food/Lifestyle
Applies to: Humulin N (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.
Moderate:
atenolol Alcohol (Ethanol)
Applies to: atenolol
Ethanol and atenolol may have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, or changes in pulse or heart rate, especially when treatment is started, the dose is changed, or treatment is restarted. Tell your doctor promptly if these symptoms occur and seek urgent medical help if you faint or have severe dizziness. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. 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.
Moderate:
atenolol multivitamins with minerals
Applies to: atenolol
Using atenolol together with multivitamins with minerals may decrease the effects of atenolol. Separate the administration times of atenolol and multivitamins with minerals by at least 2 hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test 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.
Disease interactions
29 potential interactions Applies to: 28 conditions, including High Cholesterol, Allergies, Heart Failure, Asthma, and COPD.
Adrenal Insufficiency
Moderate:
Humulin N
The insulin isophane (NPH) in Humulin N 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.
Allergies
Major:
atenolol
Atenolol has a major potential interaction with Allergies.
The use of beta-adrenergic receptor blocking agents (aka beta-blockers) in patients with a history of allergic reactions or anaphylaxis may be associated with heightened reactivity to culprit allergens. The frequency and/or severity of attacks may be increased during beta-blocker therapy. In addition, these patients may be refractory to the usual doses of epinephrine used to treat acute hypersensitivity reactions and may require a beta-agonist such as isoproterenol.
Anorexia/Feeding Problems
Moderate:
Humulin N
The insulin isophane (NPH) in Humulin N 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.
Asthma
Moderate:
atenolol
Atenolol has a moderate potential interaction with Asthma.
Patients with bronchospastic disease, should, in general, not receive beta blockers, including cardioselective beta-blockers. Because of the relative beta-1 selectivity, cardioselective beta-blockers may be used in patients with bronchospastic disease who do not respond to, or cannot tolerate, other antihypertensive treatment. Because beta-1 selectivity is not absolute, the lowest possible dose of these agents should be used. Consider administering in smaller doses to avoid the higher plasma levels associated with the longer dosing intervals. If dosage must be increased, dividing the dose should be considered to achieve lower peak blood levels. It is recommended to have bronchodilators, including beta-2 agonists, readily available or administered concomitantly if necessary.
Autonomic Neuropathy
Moderate:
Humulin N
The insulin isophane (NPH) in Humulin N 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.
Cardiogenic Shock
Major:
atenolol
Atenolol has a major potential interaction with Cardiogenic Shock.
The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with hypotension or cardiogenic shock. Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to further depress cardiac output and blood pressure, which can be detrimental in these patients.
Cerebrovascular Insufficiency
Moderate:
atenolol
Atenolol has a moderate potential interaction with Cerebrovascular Insufficiency.
Beta-adrenergic blocking agents (beta-blockers), should be used with caution in patients with cerebrovascular insufficiency because of their potential effects relative to blood pressure and pulse. If signs or symptoms suggesting reduced cerebral blood flow are observed, consideration should be given to discontinuing these agents.
COPD
Moderate:
atenolol
Atenolol has a moderate potential interaction with COPD.
Patients with bronchospastic disease, should, in general, not receive beta blockers, including cardioselective beta-blockers. Because of the relative beta-1 selectivity, cardioselective beta-blockers may be used in patients with bronchospastic disease who do not respond to, or cannot tolerate, other antihypertensive treatment. Because beta-1 selectivity is not absolute, the lowest possible dose of these agents should be used. Consider administering in smaller doses to avoid the higher plasma levels associated with the longer dosing intervals. If dosage must be increased, dividing the dose should be considered to achieve lower peak blood levels. It is recommended to have bronchodilators, including beta-2 agonists, readily available or administered concomitantly if necessary.
Diabetes Mellitus
Major:
atenolol
Atenolol has a major potential interaction with Diabetes Mellitus.
Beta-adrenergic receptor blocking agents (aka beta-blockers) may mask symptoms of hypoglycemia such as tremors, tachycardia and blood pressure changes. In addition, the nonselective beta-blockers (e.g., propranolol, pindolol, timolol) may inhibit catecholamine-mediated glycogenolysis, thereby potentiating insulin-induced hypoglycemia and delaying the recovery of normal blood glucose levels. Since cardioselectivity is not absolute, larger doses of beta-1 selective agents may demonstrate these effects as well. Therapy with beta-blockers should be administered cautiously in patients with diabetes or predisposed to spontaneous hypoglycemia.
Glaucoma/Intraocular Hypertension
Moderate:
atenolol
Atenolol has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Systemic beta-adrenergic receptor blocking agents (aka beta-blockers) may lower intraocular pressure. Therefore, patients with glaucoma or intraocular hypertension may require adjustments in their ophthalmic regimen following a dosing change or discontinuation of beta-blocker therapy.
Heart Block
Major:
atenolol
Atenolol has a major potential interaction with Heart Block.
The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with sinus bradyarrhythmia or heart block greater than the first degree (unless a functioning pacemaker is present). Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to exacerbate these conditions.
Heart Failure
Major:
atenolol
Atenolol has a major potential interaction with Heart Failure.
Beta-adrenergic receptor blocking agents (aka beta-blockers) in general should not be used in patients with overt congestive heart failure (CHF). Sympathetic stimulation may be important in maintaining the hemodynamic function in these patients, thus beta-blockade can worsen the heart failure. However, therapy with beta-blockers may be beneficial and can be administered cautiously in some CHF patients provided they are well compensated and receiving digitalis, diuretics, an ACE inhibitor, and/or nitrates. Carvedilol, specifically, is indicated for use with these agents in the treatment of mild to severe heart failure of ischemic or cardiomyopathic origin. There is also increasing evidence that the addition of a beta-blocker to standard therapy can improve morbidity and mortality in patients with advanced heart failure, although it is uncertain whether effectiveness varies significantly with the different agents. Data from one meta-analysis study suggest a greater reduction of mortality risk for nonselective beta-blockers than for beta-1 selective agents.
Hemodialysis
Major:
atenolol
Atenolol has a major potential interaction with Hemodialysis.
Atenolol is moderately removed by conventional hemodialysis. Patients on hemodialysis should receive a dose of atenolol following each dialysis session when they are hemodynamically stable to avoid marked falls in blood pressure. The hemodynamic status should be closely monitored before and after the dose.
High Cholesterol
Moderate:
atenolol
Atenolol has a moderate potential interaction with High Cholesterol.
Beta-adrenergic receptor blocking agents (aka beta-blockers) may alter serum lipid profiles. Increases in serum VLDL and LDL cholesterol and triglycerides, as well as decreases in HDL cholesterol, have been reported with some beta-blockers. Patients with preexisting hyperlipidemia may require closer monitoring during beta-blocker therapy, and adjustments made accordingly in their lipid-lowering regimen.
Hyperthyroidism
Moderate:
atenolol
Atenolol has a moderate potential interaction with Hyperthyroidism.
When beta-adrenergic receptor blocking agents (aka beta-blockers) are used to alleviate symptoms of hyperthyroidism such as tachycardia, anxiety, tremor and heat intolerance, abrupt withdrawal can exacerbate thyrotoxicosis or precipitate a thyroid storm. To minimize this risk, cessation of beta-blocker therapy, when necessary, should occur gradually with incrementally reduced dosages over a period of 1 to 2 weeks. Patients should be advised not to discontinue treatment without first consulting with the physician. Close monitoring is recommended during and after therapy withdrawal.
Hypokalemia
Moderate:
Humulin N
The insulin isophane (NPH) in Humulin N 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).
Hypotension
Major:
atenolol
Atenolol has a major potential interaction with Hypotension.
The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with hypotension or cardiogenic shock. Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to further depress cardiac output and blood pressure, which can be detrimental in these patients.
Ischemic Heart Disease
Major:
atenolol
Atenolol has a major potential interaction with Ischemic Heart Disease.
Heightened sensitivity to catecholamines may occur after prolonged use of beta-adrenergic receptor blocking agents (aka beta-blockers). Exacerbation of angina, myocardial infarction and ventricular arrhythmias have been reported in patients with coronary artery disease following abrupt withdrawal of therapy. Cessation of beta-blocker therapy, whenever necessary, should occur gradually with incrementally reduced dosages over a period of 1 to 2 weeks in patients with coronary insufficiency. Patients should be advised not to discontinue treatment without first consulting with the physician. In patients who experience an exacerbation of angina following discontinuation of beta-blocker therapy, the medication should generally be reinstituted, at least temporarily, along with other clinically appropriate measures.
Liver Disease
Moderate:
Humulin N
The insulin isophane (NPH) in Humulin N 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
The insulin isophane (NPH) in Humulin N 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.
Myasthenia Gravis
Moderate:
atenolol
Atenolol has a moderate potential interaction with Myasthenia Gravis.
Beta-adrenergic receptor blocking agents (aka beta-blockers) may potentiate muscle weakness consistent with certain myasthenic symptoms such as diplopia, ptosis, and generalized weakness. Several beta-blockers have been associated rarely with aggravation of muscle weakness in patients with preexisting myasthenia gravis or myasthenic symptoms. Use cautiously in patients with myasthenia gravis.
Panhypopituitarism
Moderate:
Humulin N
The insulin isophane (NPH) in Humulin N 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.
Peripheral Arterial Disease
Major:
atenolol
Atenolol has a major potential interaction with Peripheral Arterial Disease.
Due to their negative inotropic and chronotropic effects on the heart, beta-adrenergic receptor blocking agents (aka beta-blockers) reduce cardiac output and may precipitate or aggravate symptoms of arterial insufficiency in patients with peripheral vascular disease. In addition, the nonselective beta-blockers (e.g., propranolol, pindolol, timolol) may attenuate catecholamine-mediated vasodilation during exercise by blocking beta-2 receptors in peripheral vessels. Therapy with beta-blockers should be administered cautiously in patients with peripheral vascular disease. Close monitoring for progression of arterial obstruction is advised.
Pheochromocytoma
Moderate:
atenolol
Atenolol has a moderate potential interaction with Pheochromocytoma.
Administration of beta-blockers alone in the setting of pheochromocytoma has been associated with a paradoxical increase in blood pressure due to the attenuation of beta receptor-mediated vasodilatation in skeletal muscle. In patients with pheochromocytoma, an alpha-blocking agent should be initiated prior to the use of any beta-blocking agent. Caution should be taken in the administration of these agents to patients suspected of having pheochromocytoma.
Psoriasis
Moderate:
atenolol
Atenolol has a moderate potential interaction with Psoriasis.
The use of beta-blockers in psoriatic patients should be carefully weighed since the use of these agents may cause an aggravation in psoriasis.
Renal Dysfunction
Major:
atenolol
Atenolol has a major potential interaction with Renal Dysfunction.
Atenolol is eliminated by the kidney. Significant accumulation of the drug occurs in patients with a creatinine clearance below 35 mL/min/1.73 m2. Dosage adjustments are recommended for these patients.
Moderate:
Humulin N
The insulin isophane (NPH) in Humulin N 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.
Sinus Node Dysfunction
Major:
atenolol
Atenolol has a major potential interaction with Sinus Node Dysfunction.
The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with sinus bradyarrhythmia or heart block greater than the first degree (unless a functioning pacemaker is present). Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to exacerbate these conditions.
Tachyarrhythmia
Moderate:
atenolol
Atenolol has a moderate potential interaction with Tachyarrhythmia.
Beta-adrenergic blockade in patients with Wolff-Parkinson-White syndrome and tachycardia has been associated with severe bradycardia requiring treatment with a pacemaker. In one case, this result was reported after an initial dose of 5 mg propranolol. The use of beta-adrenergic receptor blocking agents (aka beta-blockers) should be administered cautiously in these patients.
