Disease interactions

39 potential interactions Applies to: 34 conditions, including High Cholesterol, Heart Failure, Seizures, Hypokalemia, and Hypotension.

Acidosis

Moderate:

LidoSite

The EPINEPHrine in LidoSite has a moderate potential interaction with Acidosis.

Acidosis, hypoxia, and hypercapnia may reduce the effectiveness of sympathomimetic amines in raising blood pressure. These conditions should be corrected before initiating therapy with sympathomimetic amines, if possible. Monitoring the patients acid-base balance, carbon dioxide levels, and oxygen saturation is recommended.

Cardiovascular Conditions and Disorders

Major:

LidoSite

The EPINEPHrine in LidoSite has a major potential interaction with Cardiovascular Conditions and Disorders.

Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.

Major:

tofacitinib

Tofacitinib has a major potential interaction with Cardiovascular Conditions and Disorders.

In a major safety study of a Janus kinase (JAK) inhibitor, tofacitinib, in rheumatoid arthritis patients 50 years and older with at least 1 cardiovascular risk factor, higher rates of all-cause mortality (including sudden cardiovascular death) and major adverse cardiovascular events (MACE) (defined as cardiovascular death, myocardial infarction, and stroke) were observed with the JAK inhibitor when compared with tumor necrosis factor (TNF) blockers. Patients who were current or past smokers had an additional increased risk. Based on a shared mechanism of action, this risk should be considered for other JAK inhibitors, including baricitinib, upadacitinib, ruxolitinib, fedratinib, ritlecitinib, deuruxolitinib, and pacritinib. Consider the benefits and risks for each individual patient prior and during treatment with JAK inhibitors, especially in patients with other cardiovascular risk factors, history of cardiovascular events, and patients who are current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and what to do if they occur.

Dehydration

Major:

LidoSite

The EPINEPHrine in LidoSite has a major potential interaction with Dehydration.

The use of sympathomimetic amines has been infrequently associated with significant hypotension especially in dehydrated patients secondary to the drug's beta-2 mediated vasodilation. Hypovolemia should be corrected, if possible, before administering sympathomimetic amines. Blood pressure and ECG should be monitored at regular intervals. Monitoring of cardiac output and pulmonary wedge pressure may also be desired.

Diabetes Mellitus

Moderate:

LidoSite

The EPINEPHrine in LidoSite has a moderate potential interaction with Diabetes Mellitus.

Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.

Moderate:

tofacitinib

Tofacitinib has a moderate potential interaction with Diabetes Mellitus.

Heart Failure

Major:

LidoSite

The lidocaine in LidoSite has a major potential interaction with Heart Failure.

Antiarrhythmic agents can induce severe hypotension (particularly with IV administration) or induce or worsen congestive heart failure (CHF). Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.

Hemoglobinopathy

Moderate:

tofacitinib

Tofacitinib has a moderate potential interaction with Hemoglobinopathy.

Adverse hematologic effects including neutropenia, lymphocytosis, and anemia have been associated with the use of tofacitinib. It is recommended to avoid starting therapy in patients with absolute lymphocyte counts (ALC) less than 500 cells/mm3, absolute neutrophil counts (ANC) less than 1000 cells/mm3, or hemoglobin levels less than 9 g/dL. For persistent ANC of 500 to 1000 cells/mm3, hemoglobin levels less than 8 g/dL, or a hemoglobin level drop greater than 2 g/dL, therapy should be interrupted until ANC is greater than 1000 cells/mm3 and hemoglobin values have normalized. Treatment with tofacitinib is not recommended in patients who develop a confirmed ALC less than 500 cells/mm3 or an ANC less than 500 cells/mm3. Lymphocyte counts should be monitored at baseline and every 3 months thereafter; neutrophil counts and hemoglobin should be monitored at baseline, after 4 to 8 weeks of therapy, and every 3 months thereafter. Treatment should be modified based on ALC, ANC, and/or hemoglobin levels. Caution is recommended in patients who may be at increased risk.

High Cholesterol

Moderate:

tofacitinib

Tofacitinib has a moderate potential interaction with High Cholesterol.

Treatment with tofacitinib was associated with dose-dependent increases in lipid parameters (including total cholesterol, low-density lipoprotein [LDL] cholesterol, high-density lipoprotein [HDL] cholesterol); maximum effects generally occurred within 6 weeks. Lipid parameters should be assessed about 4 to 8 weeks after initiation of therapy. Patients should be managed according to clinical guidelines for the management of hyperlipidemia.

Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.

Immunodeficiency

Major:

tofacitinib

Tofacitinib has a major potential interaction with Immunodeficiency.

Serious and sometimes fatal infections due to bacterial, mycobacterial, invasive fungal, viral, or other opportunistic pathogens have been reported in patients receiving tofacitinib. Use of tofacitinib should be avoided in patients with an active, serious infection, including localized infections. The risks and benefits of treatment should be considered before starting tofacitinib in patients: with chronic/recurrent infection, who have been exposed to tuberculosis, with history of serious/opportunistic infection, who have resided/traveled in areas of endemic tuberculosis/mycoses, or with underlying conditions that may predispose them to infection. Patients should be closely monitored for signs/symptoms of infection during and after tofacitinib treatment. Tofacitinib should be interrupted if a patient develops a serious infection, an opportunistic infection, or sepsis. A patient who develops a new infection during treatment with tofacitinib should undergo prompt and complete diagnostic testing appropriate for an immunocompromised patient; appropriate antimicrobial therapy should be started, and the patient should be monitored closely. Caution is also recommended in patients with history of chronic lung disease, or in those who develop interstitial lung disease, as they may be more prone to infections.

Infection

A patient who develops a new infection during treatment with tofacitinib should undergo prompt and complete diagnostic testing appropriate for an immunocompromised patient; appropriate antimicrobial therapy should be started, and the patient should be monitored closely. Caution is also recommended in patients with history of chronic lung disease, or in those who develop interstitial lung disease, as they may be more prone to infections.

Infectious Hepatitis

Moderate:

tofacitinib

Tofacitinib has a moderate potential interaction with Infectious Hepatitis.

Viral reactivation (including cases of herpes virus reactivation [e.g., herpes zoster]) was observed in clinical trials with tofacitinib; postmarketing cases of hepatitis B reactivation have been reported with tofacitinib. Patients should be screened for viral hepatitis in accordance with clinical guidelines before starting therapy with tofacitinib. Close monitoring is recommended, and appropriate supportive treatment should be initiated if appropriate.

Liver Disease

Major:

LidoSite

The lidocaine in LidoSite has a major potential interaction with Liver Disease.

Lidocaine is rapidly and extensively metabolized by the liver. Less than 10% is eliminated unchanged in the urine. Several inactive and two active forms (MEGX and GX) have been identified. MEGX and GX exhibit antiarrhythmic and convulsant properties. GX accumulates during prolonged intravenous lidocaine infusion. The pharmacokinetic disposition of lidocaine is altered by changes in hepatic function, including hepatic blood flow. Therapy with lidocaine should be administered cautiously and dosing modifications for repeated or loading and maintenance doses may be necessary. Clinical monitoring of cardiac (continuous ECG) is required and serum metabolite concentrations and monitoring hepatic function are recommended.

Moderate:

tofacitinib

Tofacitinib has a moderate potential interaction with Liver Disease.

Treatment with tofacitinib was associated with an increased incidence of liver enzyme elevation compared to placebo. No dose adjustment of tofacitinib is needed in patients with mild liver dysfunction. Tofacitinib-treated patients with moderate liver dysfunction had greater tofacitinib blood levels than those with normal liver function; therefore, dose adjustment of tofacitinib is recommended in these patients. Tofacitinib has not been studied in patients with severe liver dysfunction, and its use is not recommended in these patients. The safety and efficacy of tofacitinib has not been studied in patients with positive hepatitis B virus or hepatitis C virus serology. Routine monitoring of liver tests and prompt investigation of the causes of liver enzyme elevations is recommended to identify potential cases of drug-induced liver injury; if drug-induced liver injury is suspected, therapy should be interrupted until this diagnosis has been excluded.

Lymphocytopenia

Moderate:

tofacitinib

Tofacitinib has a moderate potential interaction with Lymphocytopenia.

Adverse hematologic effects including neutropenia, lymphocytosis, and anemia have been associated with the use of tofacitinib. It is recommended to avoid starting therapy in patients with absolute lymphocyte counts (ALC) less than 500 cells/mm3, absolute neutrophil counts (ANC) less than 1000 cells/mm3, or hemoglobin levels less than 9 g/dL. For persistent ANC of 500 to 1000 cells/mm3, hemoglobin levels less than 8 g/dL, or a hemoglobin level drop greater than 2 g/dL, therapy should be interrupted until ANC is greater than 1000 cells/mm3 and hemoglobin values have normalized. Treatment with tofacitinib is not recommended in patients who develop a confirmed ALC less than 500 cells/mm3 or an ANC less than 500 cells/mm3. Lymphocyte counts should be monitored at baseline and every 3 months thereafter; neutrophil counts and hemoglobin should be monitored at baseline, after 4 to 8 weeks of therapy, and every 3 months thereafter. Treatment should be modified based on ALC, ANC, and/or hemoglobin levels. Caution is recommended in patients who may be at increased risk.

Magnesium Imbalance

Moderate:

LidoSite

The lidocaine in LidoSite has a moderate potential interaction with Magnesium Imbalance.

Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.

Neurological Disorders

Renal Dysfunction

Major:

LidoSite

The lidocaine in LidoSite has a major potential interaction with Renal Dysfunction.

Lidocaine is primarily eliminated by the kidney. Less than 10% is eliminated unchanged in the urine. Two active metabolites (MEGX and GX) have been identified that exhibit antiarrhythmic and convulsant properties. GX accumulates during prolonged intravenous lidocaine infusion. Serum concentrations of lidocaine and the active metabolites are increased and the half-life prolonged in patients with renal impairment. Therapy with lidocaine should be administered cautiously and dosing modified for repeated or maintenance doses in patients with compromised renal function. Clinical monitoring of cardiac function (continual ECG) is required and serum metabolite concentrations and monitoring renal function are recommended.

Moderate:

tofacitinib

Tofacitinib has a moderate potential interaction with Renal Dysfunction.

No dose adjustment of tofacitinib is needed in patients with mild renal dysfunction. Tofacitinib-treated patients with moderate and severe renal dysfunction had greater tofacitinib blood levels than those with normal renal function; therefore, dose adjustment of tofacitinib is recommended in patients with moderate or severe renal dysfunction (including but not limited to those with severe dysfunction undergoing hemodialysis). Caution should be exercised when using tofacitinib in these patients.

Seizures

Major:

LidoSite

The lidocaine in LidoSite has a major potential interaction with Seizures.

Seizures have occurred during lidocaine therapy and have been associated with the rapid administration of a large intravenous doses or accumulation of active metabolites with maintenance therapy. Therapy with lidocaine should be administered cautiously to patients with or predisposed to seizure disorders. Clinical monitoring of cardiac (continuous ECG) is required, and serum metabolite concentrations are recommended.

Smoking

Major:

tofacitinib

Tofacitinib has a major potential interaction with Smoking.

In a major safety study of a Janus kinase (JAK) inhibitor, tofacitinib, in rheumatoid arthritis patients 50 years and older with at least 1 cardiovascular risk factor, higher rates of all-cause mortality (including sudden cardiovascular death) and major adverse cardiovascular events (MACE) (defined as cardiovascular death, myocardial infarction, and stroke) were observed with the JAK inhibitor when compared with tumor necrosis factor (TNF) blockers. Patients who were current or past smokers had an additional increased risk. Based on a shared mechanism of action, this risk should be considered for other JAK inhibitors, including baricitinib, upadacitinib, ruxolitinib, fedratinib, ritlecitinib, deuruxolitinib, and pacritinib. Consider the benefits and risks for each individual patient prior and during treatment with JAK inhibitors, especially in patients with other cardiovascular risk factors, history of cardiovascular events, and patients who are current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and what to do if they occur.

Major:

tofacitinib

Tofacitinib has a major potential interaction with Smoking.

Malignancies (including lymphomas and solid tumors) have been reported in patients treated with tofacitinib, baricitinib, upadacitinib, deuruxolitinib and other Janus kinase (JAK) inhibitors used to treat inflammatory conditions. Patients who are current or past smokers are at additional increased risk of malignancies. Based on a shared mechanism of action, this risk should be considered for other JAK inhibitors, including ruxolitinib, pacritinib, and fedratinib. Before starting or continuing therapy, the benefits and risks for the individual patient should be considered, especially in patients with a known malignancy (other than successfully treated nonmelanoma skin cancer), patients who develop a malignancy during therapy, and patients who are current or past smokers. Periodic skin examination is recommended for patients who are at increased risk for skin cancer.

Thrombotic/Thromboembolic Disorder

Major:

tofacitinib

Tofacitinib has a major potential interaction with Thrombotic/Thromboembolic Disorder.

Thrombosis (including deep venous thrombosis, pulmonary embolism, cerebral venous sinus thrombosis, and arterial thrombosis) has occurred in patients treated for inflammatory conditions with Janus kinase (JAK) inhibitors, including baricitinib, tofacitinib, deuruxolitinib and upadacitinib. Many of these adverse events were serious and some resulted in death. Based on a shared mechanism of action, this risk should be considered for other JAK inhibitors, including ruxolitinib, fedratinib, and pacritinib. In general, JAK inhibitors should be avoided in patients who may be at increased risk of thrombosis. Tofacitinib should be used at the lowest effective dose and for the shortest duration needed to achieve/maintain therapeutic response when treating ulcerative colitis. If symptoms of thrombosis occur in any patients receiving JAK inhibitors, treatment should be discontinued and patients should be evaluated promptly and treated appropriately.
