Drug interactions
Moderate drug interactions
Moderate:
metoprolol sildenafil
Applies to: metoprolol and sildenafil
Sildenafil can add to the blood pressure-lowering effect of metoprolol. Contact your doctor if you experience signs and symptoms of low blood pressure such as dizziness, lightheadedness, fainting, flushing, headache, or a rapid pulse or heart rate. You may be more likely to experience these problems at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. 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.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
metoprolol Food/Lifestyle
Applies to: metoprolol
Food can enhance the levels of metoprolol in your body. You should take metoprolol at the same time each day, preferably with or immediately following meals. This will make it easier for your body to absorb the medication. Avoid drinking alcohol, which could increase drowsiness and dizziness while you are taking metoprolol. Metoprolol is only part of a complete program of treatment that also includes diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.
Moderate:
sildenafil Food/Lifestyle
Applies to: sildenafil
If you are receiving therapy with sildenafil you should avoid the regular consumption of large amounts of grapefruits and grapefruit juice. Grapefruit can raise the levels of sildenafil in your body and delay the time it takes for the medication to work. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
Moderate:
metoprolol multivitamins with minerals
Applies to: metoprolol
Using metoprolol together with multivitamins with minerals may decrease the effects of metoprolol. Separate the administration times of metoprolol 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
44 potential interactions Applies to: 40 conditions, including High Cholesterol, Allergies, Heart Failure, Asthma, and COPD.
Alcoholism
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Alcoholism.
Alcohol consumption may intensify the pressure-lowering effects of mild vasodilators, such as phosphodiesterase 5 (PDE5) inhibitors. Therefore, patients that consume alcohol should be warned to limit alcohol intake while receiving these agents.
Allergies
Major:
metoprolol
Metoprolol 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.
Asthma
Moderate:
metoprolol
Metoprolol 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.
Bleeding Associated with Coagulation Defect
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Bleeding Associated with Coagulation Defect.
The safety of sildenafil in patients with bleeding disorders or active peptic ulceration is unknown. In clinical studies, the incidence of bleeding (i.e., epistaxis) was increased in patients with pulmonary arterial hypertension secondary to connective tissue disease and in patients on concomitant therapy with an oral vitamin K antagonist. There have been postmarketing reports of bleeding events in patients treated with sildenafil for erectile dysfunction.
Bleeding Disorder
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Bleeding Disorder.
The safety of sildenafil in patients with bleeding disorders or active peptic ulceration is unknown. In clinical studies, the incidence of bleeding (i.e., epistaxis) was increased in patients with pulmonary arterial hypertension secondary to connective tissue disease and in patients on concomitant therapy with an oral vitamin K antagonist. There have been postmarketing reports of bleeding events in patients treated with sildenafil for erectile dysfunction.
Cardiogenic Shock
Major:
metoprolol
Metoprolol 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.
Cardiovascular Conditions and Disorders
Major:
sildenafil
Sildenafil has a major potential interaction with Cardiovascular Conditions and Disorders.
The use of phosphodiesterase-5 (PDE5) inhibitors is not recommended in patients with preexisting cardiovascular disease for whom sexual activity is inadvisable due to the potential cardiac risk. Physicians should also consider the vasodilatory effect of these drugs and whether they may adversely affect patients with underlying cardio- and/or cerebrovascular conditions, in particular those who have suffered a myocardial infarction, stroke, or life-threatening arrhythmia within the last 6 months; those with resting hypotension (BP < 90/50) or hypertension (BP > 170/110); and those with unstable angina associated with cardiac failure or coronary artery disease. There are no controlled clinical data on the safety or efficacy in such patients. Other adverse cardiovascular effects reported include angina pectoris, myocardial infarction, AV block, ventricular arrhythmia, tachycardia, palpitation, hypotension, postural hypotension, syncope, cerebral thrombosis, cerebrovascular hemorrhage, transient ischemic attack, cardiac arrest, heart failure, and hypertension. Many of these events occurred in patients with cardiovascular risk factors and during or shortly after sexual activity.
Cerebral Vascular Disorder
Major:
sildenafil
Sildenafil has a major potential interaction with Cerebral Vascular Disorder.
The use of phosphodiesterase-5 (PDE5) inhibitors is not recommended in patients with preexisting cardiovascular disease for whom sexual activity is inadvisable due to the potential cardiac risk. Physicians should also consider the vasodilatory effect of these drugs and whether they may adversely affect patients with underlying cardio- and/or cerebrovascular conditions, in particular those who have suffered a myocardial infarction, stroke, or life-threatening arrhythmia within the last 6 months; those with resting hypotension (BP < 90/50) or hypertension (BP > 170/110); and those with unstable angina associated with cardiac failure or coronary artery disease. There are no controlled clinical data on the safety or efficacy in such patients. Other adverse cardiovascular effects reported include angina pectoris, myocardial infarction, AV block, ventricular arrhythmia, tachycardia, palpitation, hypotension, postural hypotension, syncope, cerebral thrombosis, cerebrovascular hemorrhage, transient ischemic attack, cardiac arrest, heart failure, and hypertension. Many of these events occurred in patients with cardiovascular risk factors and during or shortly after sexual activity.
Cerebrovascular Insufficiency
Moderate:
metoprolol
Metoprolol 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:
metoprolol
Metoprolol 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:
metoprolol
Metoprolol 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:
metoprolol
Metoprolol 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.
Hearing Loss
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Hearing Loss.
Use of phosphodiesterase-5 (PDE5) inhibitors has been associated with sudden decrease or loss of hearing, which may be accompanied by tinnitus or dizziness. Patients with hearing problems should stop taking these agents and seek prompt medical care.
Heart Block
Major:
metoprolol
Metoprolol 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:
metoprolol
Metoprolol 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:
metoprolol
Metoprolol has a major potential interaction with Hemodialysis.
Therapy with beta-adrenergic receptor blocking agents (aka beta-blockers) should be administered cautiously in patients requiring hemodialysis. When given after dialysis, hemodynamic stability should be established prior to drug administration to avoid marked falls in blood pressure. The hemodynamic status should be closely monitored before and after the dose.
High Cholesterol
Moderate:
metoprolol
Metoprolol 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.
History - Cerebrovascular Disease
Major:
sildenafil
Sildenafil has a major potential interaction with History - Cerebrovascular Disease.
The use of phosphodiesterase-5 (PDE5) inhibitors is not recommended in patients with preexisting cardiovascular disease for whom sexual activity is inadvisable due to the potential cardiac risk. Physicians should also consider the vasodilatory effect of these drugs and whether they may adversely affect patients with underlying cardio- and/or cerebrovascular conditions, in particular those who have suffered a myocardial infarction, stroke, or life-threatening arrhythmia within the last 6 months; those with resting hypotension (BP < 90/50) or hypertension (BP > 170/110); and those with unstable angina associated with cardiac failure or coronary artery disease. There are no controlled clinical data on the safety or efficacy in such patients. Other adverse cardiovascular effects reported include angina pectoris, myocardial infarction, AV block, ventricular arrhythmia, tachycardia, palpitation, hypotension, postural hypotension, syncope, cerebral thrombosis, cerebrovascular hemorrhage, transient ischemic attack, cardiac arrest, heart failure, and hypertension. Many of these events occurred in patients with cardiovascular risk factors and during or shortly after sexual activity.
History - Myocardial Infarction
Major:
sildenafil
Sildenafil has a major potential interaction with History - Myocardial Infarction.
The use of phosphodiesterase-5 (PDE5) inhibitors is not recommended in patients with preexisting cardiovascular disease for whom sexual activity is inadvisable due to the potential cardiac risk. Physicians should also consider the vasodilatory effect of these drugs and whether they may adversely affect patients with underlying cardio- and/or cerebrovascular conditions, in particular those who have suffered a myocardial infarction, stroke, or life-threatening arrhythmia within the last 6 months; those with resting hypotension (BP < 90/50) or hypertension (BP > 170/110); and those with unstable angina associated with cardiac failure or coronary artery disease. There are no controlled clinical data on the safety or efficacy in such patients. Other adverse cardiovascular effects reported include angina pectoris, myocardial infarction, AV block, ventricular arrhythmia, tachycardia, palpitation, hypotension, postural hypotension, syncope, cerebral thrombosis, cerebrovascular hemorrhage, transient ischemic attack, cardiac arrest, heart failure, and hypertension. Many of these events occurred in patients with cardiovascular risk factors and during or shortly after sexual activity.
Hyperthyroidism
Moderate:
metoprolol
Metoprolol 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.
Moderate:
metoprolol
Metoprolol has a moderate potential interaction with Hyperthyroidism.
During chronic administration, the clearance of beta-blockers that are primarily metabolized by the liver (e.g., labetalol, metoprolol, penbutolol, propranolol) may be increased in patients with hyperthyroidism due to increased liver blood flow and enhanced activity of drug-metabolizing enzymes. Pharmacokinetic studies have demonstrated an approximately 50% increase in systemic clearance of propranolol during long-term therapy. In general, the dosage required to achieve therapeutic blood concentrations in such patients may be higher than that required in euthyroid patients and should be individualized.
Hypotension
Major:
metoprolol
Metoprolol 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.
Major:
sildenafil
Sildenafil has a major potential interaction with Hypotension.

There are no controlled clinical data on the safety or efficacy in such patients. Other adverse cardiovascular effects reported include angina pectoris, myocardial infarction, AV block, ventricular arrhythmia, tachycardia, palpitation, hypotension, postural hypotension, syncope, cerebral thrombosis, cerebrovascular hemorrhage, transient ischemic attack, cardiac arrest, heart failure, and hypertension. Many of these events occurred in patients with cardiovascular risk factors and during or shortly after sexual activity.
Ischemic Heart Disease
Major:
metoprolol
Metoprolol 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
Major:
metoprolol
Metoprolol has a major potential interaction with Liver Disease.
Metoprolol is primarily metabolized by the liver. Patients with liver disease may be at greater risk for adverse effects from metoprolol due to decreased drug clearance. Therapy with metoprolol should be administered cautiously in patients with liver disease. Dosage adjustments may be necessary.
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Liver Disease.
Phosphodiesterase 5 (PDE-5) inhibitors are cleared predominantly by hepatic metabolism. The pharmacokinetic disposition of these agents has not been assessed in patients with severe hepatic impairment. No dosage modification is recommended for patients with mild to moderate hepatic impairment, however, therapy with these agents should not be administered to patients with severe hepatic impairment. In patients with mild hepatic impairment a lower dose of these agents should be used as initial therapy.
Myasthenia Gravis
Moderate:
metoprolol
Metoprolol 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.
Myeloproliferative Disorders
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Myeloproliferative Disorders.
Prolonged erection greater than 4 hours and priapism (painful erections greater than 6 hours) have been reported during treatment with phosphodiesterase-5 (PDE 5) inhibitors. Priapism may result in penile tissue damage and permanent loss of potency if not treated promptly. These agents should be used cautiously in patients with conditions that may predispose them to priapism such as sickle cell anemia, multiple myeloma, or leukemia, and those with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease). If an erection persists longer than 4 hours, the patient should seek immediate medical assistance.
Optic Nerve Disorder
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Optic Nerve Disorder.
Sildenafil for the treatment of erectile dysfunction (ED) should be used with caution and only if the benefit outweighs the risk in patients with a history of non-arteritic anterior ischemic optic neuropathy (NAION) or with retinitis pigmentosa. Use of sildenafil for the treatment of pulmonary arterial hypertension is not recommended in patients with retinitis pigmentosa. Advise patients to seek immediate medical attention in the event of a sudden loss of vision in one or both eyes while taking sildenafil; patients taking sildenafil for ED should immediately stop treatment. Most patients who developed NAION during therapy with sildenafil had underlying anatomic or vascular risk factors, including low cup to disc ratio ("crowded disc").
Penis Disorders
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Penis Disorders.
Prolonged erection greater than 4 hours and priapism (painful erections greater than 6 hours) have been reported during treatment with phosphodiesterase-5 (PDE 5) inhibitors. Priapism may result in penile tissue damage and permanent loss of potency if not treated promptly. These agents should be used cautiously in patients with conditions that may predispose them to priapism such as sickle cell anemia, multiple myeloma, or leukemia, and those with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease). If an erection persists longer than 4 hours, the patient should seek immediate medical assistance.
Peptic Ulcer
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Peptic Ulcer.
The safety of sildenafil in patients with bleeding disorders or active peptic ulceration is unknown. In clinical studies, the incidence of bleeding (i.e., epistaxis) was increased in patients with pulmonary arterial hypertension secondary to connective tissue disease and in patients on concomitant therapy with an oral vitamin K antagonist. There have been postmarketing reports of bleeding events in patients treated with sildenafil for erectile dysfunction.
Peripheral Arterial Disease
Major:
metoprolol
Metoprolol 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.
Peyronie Disease
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Peyronie Disease.
Prolonged erection greater than 4 hours and priapism (painful erections greater than 6 hours) have been reported during treatment with phosphodiesterase-5 (PDE 5) inhibitors. Priapism may result in penile tissue damage and permanent loss of potency if not treated promptly. These agents should be used cautiously in patients with conditions that may predispose them to priapism such as sickle cell anemia, multiple myeloma, or leukemia, and those with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease). If an erection persists longer than 4 hours, the patient should seek immediate medical assistance.
Pheochromocytoma
Moderate:
metoprolol
Metoprolol 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:
metoprolol
Metoprolol 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
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Renal Dysfunction.
Exposure to sildenafil is increased in patients with renal dysfunction. Lower starting doses of sildenafil for the treatment of erectile dysfunction (ED) are recommended in patients with severe renal impairment (CrCl less than 30 mL/min).

Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to exacerbate these conditions.
Tachyarrhythmia
Moderate:
metoprolol
Metoprolol 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.
Tinnitus
Moderate:
sildenafil
