Drug Interaction Report

PHENobarbital has a major potential interaction with Acute Alcohol Intoxication.

The use of barbiturates is contraindicated in patients with acute alcohol intoxication exhibiting depressed vital signs. The central nervous system depressant effects of barbiturates may be additive with those of alcohol. Severe respiratory depression and death may occur. Therapy with barbiturates should be administered cautiously in patients who might be prone to acute alcohol intake.

PHENobarbital has a moderate potential interaction with Adrenal Insufficiency.

Barbiturates, especially phenobarbital, secobarbital and butabarbital, may diminish the systemic effects of exogenous and endogenous corticosteroids via induction of hepatic microsomal enzymes, thereby accelerating the metabolism of corticosteroids. In addition, barbiturates may interfere with pituitary corticotropin production. Therapy with barbiturates should be administered cautiously in patients with adrenal insufficiency. Patients with borderline hypoadrenalism should be monitored closely, and patients receiving steroid supplementation may require an adjustment in dosage when barbiturates are added to or withdrawn from their medication regimen.

PHENobarbital has a major potential interaction with Alcoholism.

Barbiturates have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use of excessive dosages. Abrupt cessation and/or a reduction in dosage may precipitate withdrawal symptoms. In patients who have developed tolerance to a barbiturate, overdosage can still produce respiratory depression and death, and cross-tolerance usually will occur with other agents in the class. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with barbiturates. It may be prudent to refrain from dispensing large quantities of medication to these patients. After prolonged use or if dependency is suspected, withdrawal of barbiturates should be undertaken gradually using a dosage-tapering schedule.

PHENobarbital has a major potential interaction with Altered Consciousness.

Barbiturates should not be administered by injection to patients in shock or coma or who have recently received another respiratory depressant. The hypnotic and hypotensive effects of these agents may be prolonged and intensified in such patients.

PHENobarbital has a major potential interaction with Asphyxia.

Barbiturates may produce severe respiratory depression, apnea, laryngospasm, bronchospasm and cough, particularly during rapid intravenous administration. In usual hypnotic dosages, the degree of respiratory depression produced is similar to that which occurs during physiologic sleep, while at higher dosages, the rate, depth and volume of respiration may be markedly decreased. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with barbiturates should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are particularly important, and equipment for resuscitation should be immediately available if the parenteral route is used. Barbiturates, especially injectable formulations, should generally be avoided in patients with sleep apnea, hypoxia, or severe pulmonary diseases in which dyspnea or obstruction is evident.

The inFLIXimab in Ixifi has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.

Cases of leukopenia, neutropenia, thrombocytopenia, and pancytopenia, some with a fatal outcome, have been reported in patients treated with TNF blocking agents. Caution should be exercised when treating patients who have ongoing or a history of significant hematologic abnormalities. Discontinuation of therapy should be considered in patients with confirmed significant hematologic abnormalities.

PHENobarbital has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.

Hematologic toxicity, including agranulocytosis, thrombocytopenic purpura and megaloblastic anemia, has been reported rarely during use of barbiturates. Therapy with barbiturates should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow suppression. Blood counts are recommended prior to and periodically during long-term therapy, and patients should be instructed to immediately report any signs or symptoms suggestive of blood dyscrasia such as fever, sore throat, local infection, easy bruising, petechiae, bleeding, pallor, dizziness, or jaundice. Barbiturate therapy should be discontinued if blood dyscrasias occur.

The inFLIXimab in Ixifi has a major potential interaction with Central Nervous System Disorders.

The use of TNF blocking agents has been associated with rare cases of CNS manifestations of systemic vasculitis, seizure and new onset or exacerbation of clinical symptoms and/or radiographic evidence of central nervous system demyelinating disorders, including multiple sclerosis and optic neuritis, and peripheral demyelinating disorders, including Guillain-Barré syndrome. Care should be exercised when considering the use of these agents in patients with neurologic disorders and discontinuing the agent is recommended if these disorders develop during therapy.

The inFLIXimab in Ixifi has a moderate potential interaction with COPD.

In studies, patients with moderate to severe chronic obstructive pulmonary disease (COPD) treated with infliximab developed more malignancies, the majority of lung or head and neck origin than those treated with placebo. Caution should be exercised when considering the use of infliximab in patients with moderate to severe COPD.

PHENobarbital has a moderate potential interaction with Depression.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

PHENobarbital has a moderate potential interaction with Depression.

Barbiturates depress the central nervous system and may cause or exacerbate mental depression. Therapy with barbiturates should be administered cautiously in patients with a history of depression or suicidal tendencies. It may be prudent to refrain from dispensing large quantities of medication to these patients.

PHENobarbital has a major potential interaction with Dermatitis, Drug-Induced.

Skin eruptions may precede rare but potentially fatal barbiturate-induced reactions such as systemic lupus erythematosus and exfoliative dermatitis, the latter of which may be accompanied by hepatitis and jaundice. Therapy with barbiturates should be administered cautiously in patients with preexisting drug-induced dermatitis, since it may delay the recognition of a potential reaction to barbiturates. Barbiturate therapy should be withdrawn promptly at the first sign of a dermatologic adverse effect. However, cutaneous reactions may proceed to an irreversible stage even after cessation of medication due to the slow rate of metabolism and excretion of barbiturates. Patients should be advised to promptly report signs that may indicate impending development of barbiturate-related cutaneous lesions, including high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Rashes may be more likely to occur with phenobarbital and mephobarbital.

PHENobarbital has a major potential interaction with Drug Dependence.

Barbiturates have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use of excessive dosages. Abrupt cessation and/or a reduction in dosage may precipitate withdrawal symptoms. In patients who have developed tolerance to a barbiturate, overdosage can still produce respiratory depression and death, and cross-tolerance usually will occur with other agents in the class. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with barbiturates. It may be prudent to refrain from dispensing large quantities of medication to these patients. After prolonged use or if dependency is suspected, withdrawal of barbiturates should be undertaken gradually using a dosage-tapering schedule.

PHENobarbital has a major potential interaction with Heart Disease.

The intravenous administration of barbiturates may produce severe cardiovascular reactions such as bradycardia, hypertension, or vasodilation with fall in blood pressure, particularly during rapid infusion. Parenteral therapy with barbiturates should be administered cautiously in patients with hypertension, hypotension, or cardiac disease. The intravenous administration of barbiturates should be reserved for emergency treatment of acute seizures or for anesthesia.

The inFLIXimab in Ixifi has a major potential interaction with Heart Failure.

In a study of patients with moderate to severe heart failure (New York Heart Association [NYHA] Functional Class III/IV), an increase incidence of death and hospitalization due to worsening of heart failure was observed after treatment with infliximab at 10 mg/kg. Infliximab at doses > 5 mg/kg is contraindicated in patients with moderate to severe heart failure.

PHENobarbital has a major potential interaction with High Blood Pressure.

The intravenous administration of barbiturates may produce severe cardiovascular reactions such as bradycardia, hypertension, or vasodilation with fall in blood pressure, particularly during rapid infusion. Parenteral therapy with barbiturates should be administered cautiously in patients with hypertension, hypotension, or cardiac disease. The intravenous administration of barbiturates should be reserved for emergency treatment of acute seizures or for anesthesia.

The inFLIXimab in Ixifi has a major potential interaction with History, Skin Cancer.

In clinical trials malignancies have been observed in patients receiving TNF-blockers agents. Patients with psoriasis should be monitored for non-melanoma skin cancers (NMSCs), particularly those patients who have had prior prolonged phototherapy treatment. Melanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. Postmarketing cases of fatal hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF blockers. Caution should be exercised when considering these agents in the treatment of patients with a history of malignancies or in continuing treatment in patients who develop malignancies while receiving these agents.

PHENobarbital has a moderate potential interaction with Hyperkinetic Syndrome of Childhood.

Paradoxical reactions characterized by excitability and restlessness may occur in pediatric patients with hyperactive aggressive disorders. Such patients should be monitored for signs of paradoxical stimulation during therapy with barbiturates.

PHENobarbital has a major potential interaction with Hypotension.

The intravenous administration of barbiturates may produce severe cardiovascular reactions such as bradycardia, hypertension, or vasodilation with fall in blood pressure, particularly during rapid infusion. Parenteral therapy with barbiturates should be administered cautiously in patients with hypertension, hypotension, or cardiac disease. The intravenous administration of barbiturates should be reserved for emergency treatment of acute seizures or for anesthesia.

The inFLIXimab in Ixifi has a major potential interaction with Infection.

There have been reports of serious infections, including sepsis and opportunistic infections due to bacterial, mycobacterial, invasive fungal, viral, parasitic, or other opportunistic pathogens including aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, histoplasmosis, legionellosis, listeriosis, pneumocystosis and tuberculosis with TNF blockers. Treatment with these agents should not be initiated in patients with an active infection, including clinically important localized infections. Caution and close monitoring is recommended when considering their use in patients with a history of recurrent infections, underlying conditions which may predispose them to infections, or chronic, latent, or localized infections. Administration of these agents should be discontinued if a patient develops a serious infection or sepsis.

The inFLIXimab in Ixifi has a moderate potential interaction with Infectious Hepatitis.

The use of TNF blockers has been associated with reactivation of hepatitis B, in some cases fatal, in patients who were previously infected with the hepatitis B virus (HBV). Therefore, screening for viral hepatitis should be performed in accordance with published guidelines before starting therapy with these agents. Monitor patients at risk or with evidence of current or prior HBV infection for clinical and laboratory signs of hepatitis or HBV reactivation. Prescribers should exercise caution in prescribing TNF blockers in patients previously infected with HBV. It is recommended to monitor patients with evidence of current or prior HBV infection for clinical and laboratory signs of hepatitis or HBV reactivation during and for several months following therapy. In patients who develop HBV reactivation, therapy should be stopped and antiviral therapy with appropriate supportive treatment should be initiated. The safety of resuming these agents after HBV reactivation is controlled is not known. Therefore, prescribers should weigh the risks and benefits when considering resumption of therapy.

The inFLIXimab in Ixifi has a major potential interaction with Liver Disease.

Severe hepatic reactions, including acute liver failure, jaundice, hepatitis and cholestasis, have been reported with the use of infliximab. Infliximab should be discontinued if jaundice and/or marked liver enzyme elevations (e.g., greater than or equal to 5 times the upper limit of normal) develop and a thorough investigation of the abnormality should be undertaken.

PHENobarbital has a major potential interaction with Liver Disease.

Barbiturates are extensively metabolized by the liver. The plasma clearance of barbiturates may be decreased and the half-lives prolonged in patients with impaired hepatic function. Therapy with barbiturates should be administered cautiously and initiated at reduced dosages in patients with liver disease. Barbiturates are not recommended for use in patients with cirrhosis, hepatic failure, hepatic coma, or other severe hepatic impairment.

The inFLIXimab in Ixifi has a major potential interaction with Lymphoma.

In clinical trials malignancies have been observed in patients receiving TNF-blockers agents. Patients with psoriasis should be monitored for non-melanoma skin cancers (NMSCs), particularly those patients who have had prior prolonged phototherapy treatment. Melanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. Postmarketing cases of fatal hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF blockers. Caution should be exercised when considering these agents in the treatment of patients with a history of malignancies or in continuing treatment in patients who develop malignancies while receiving these agents.

The inFLIXimab in Ixifi has a moderate potential interaction with Pancytopenia.

Cases of leukopenia, neutropenia, thrombocytopenia, and pancytopenia, some with a fatal outcome, have been reported in patients treated with TNF blocking agents. Caution should be exercised when treating patients who have ongoing or a history of significant hematologic abnormalities. Discontinuation of therapy should be considered in patients with confirmed significant hematologic abnormalities.

PHENobarbital has a moderate potential interaction with Panhypopituitarism.

Barbiturates, especially phenobarbital, secobarbital and butabarbital, may diminish the systemic effects of exogenous and endogenous corticosteroids via induction of hepatic microsomal enzymes, thereby accelerating the metabolism of corticosteroids. In addition, barbiturates may interfere with pituitary corticotropin production. Therapy with barbiturates should be administered cautiously in patients with adrenal insufficiency. Patients with borderline hypoadrenalism should be monitored closely, and patients receiving steroid supplementation may require an adjustment in dosage when barbiturates are added to or withdrawn from their medication regimen.

PHENobarbital has a major potential interaction with Porphyria.

The use of barbiturates is contraindicated in patients with a history of porphyria. Barbiturates may exacerbate acute intermittent porphyria or porphyria variegata by inducing the enzymes responsible for porphyrin synthesis.

PHENobarbital has a moderate potential interaction with Psychosis.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

PHENobarbital has a major potential interaction with Pulmonary Impairment.

Barbiturates may produce severe respiratory depression, apnea, laryngospasm, bronchospasm and cough, particularly during rapid intravenous administration. In usual hypnotic dosages, the degree of respiratory depression produced is similar to that which occurs during physiologic sleep, while at higher dosages, the rate, depth and volume of respiration may be markedly decreased. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with barbiturates should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are particularly important, and equipment for resuscitation should be immediately available if the parenteral route is used. Barbiturates, especially injectable formulations, should generally be avoided in patients with sleep apnea, hypoxia, or severe pulmonary diseases in which dyspnea or obstruction is evident.

PHENobarbital has a major potential interaction with Renal Dysfunction.

The long-acting barbiturate, phenobarbital, is partially eliminated by the kidney. The plasma clearance of phenobarbital may be decreased and the half-life prolonged in patients with impaired renal function. Therapy with phenobarbital should be administered cautiously and initiated at reduced dosages in patients with renal impairment. Since approximately 75% of a mephobarbital dose is metabolized to phenobarbital, the same precaution should be observed with mephobarbital. The remaining barbiturates, which are short- and intermediate-acting, are all negligibly excreted in the urine and may be appropriate alternatives in these patients.

PHENobarbital has a major potential interaction with Respiratory Arrest.

Barbiturates may produce severe respiratory depression, apnea, laryngospasm, bronchospasm and cough, particularly during rapid intravenous administration. In usual hypnotic dosages, the degree of respiratory depression produced is similar to that which occurs during physiologic sleep, while at higher dosages, the rate, depth and volume of respiration may be markedly decreased. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders.

Barbiturates, especially injectable formulations, should generally be avoided in patients with sleep apnea, hypoxia, or severe pulmonary diseases in which dyspnea or obstruction is evident.

PHENobarbital has a major potential interaction with Shock.

Barbiturates should not be administered by injection to patients in shock or coma or who have recently received another respiratory depressant. The hypnotic and hypotensive effects of these agents may be prolonged and intensified in such patients.

The inFLIXimab in Ixifi has a major potential interaction with Skin Cancer.

In clinical trials malignancies have been observed in patients receiving TNF-blockers agents. Patients with psoriasis should be monitored for non-melanoma skin cancers (NMSCs), particularly those patients who have had prior prolonged phototherapy treatment. Melanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. Postmarketing cases of fatal hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF blockers. Caution should be exercised when considering these agents in the treatment of patients with a history of malignancies or in continuing treatment in patients who develop malignancies while receiving these agents.

The inFLIXimab in Ixifi has a major potential interaction with Tuberculosis, Active.

Cases of reactivation of tuberculosis or new tuberculosis infections have been observed in patients receiving TNF blocking agents, including patients who have previously received treatment for latent or active tuberculosis. Cases of active tuberculosis have also occurred in patients being treated with these agents during treatment for latent tuberculosis. Prior to initiating TNF blocking agents, patients should be screened for latent tuberculosis infection with a tuberculin skin test and periodically during therapy. Patients testing positive in tuberculosis screening should be treated by standard medical practice prior to therapy with TNF blocking agents. Anti-tuberculosis therapy should also be considered prior to initiation of therapy in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent tuberculosis but having risk factors for tuberculosis infection. Tuberculosis should be strongly considered in patients who develop a new infection during treatment, especially in patients who have previously or recently traveled to countries with a high prevalence of tuberculosis, or who have had close contact with a person with active tuberculosis.

The inFLIXimab in Ixifi has a major potential interaction with Tuberculosis, Latent.

Cases of reactivation of tuberculosis or new tuberculosis infections have been observed in patients receiving TNF blocking agents, including patients who have previously received treatment for latent or active tuberculosis. Cases of active tuberculosis have also occurred in patients being treated with these agents during treatment for latent tuberculosis. Prior to initiating TNF blocking agents, patients should be screened for latent tuberculosis infection with a tuberculin skin test and periodically during therapy. Patients testing positive in tuberculosis screening should be treated by standard medical practice prior to therapy with TNF blocking agents. Anti-tuberculosis therapy should also be considered prior to initiation of therapy in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent tuberculosis but having risk factors for tuberculosis infection. Tuberculosis should be strongly considered in patients who develop a new infection during treatment, especially in patients who have previously or recently traveled to countries with a high prevalence of tuberculosis, or who have had close contact with a person with active tuberculosis.

PHENobarbital has a moderate potential interaction with Vitamin D Deficiency.

Rickets and osteomalacia have rarely been reported following prolonged use of barbiturates, possibly due to increased metabolism of vitamin D as a result of enzyme induction by barbiturates. Long-term therapy with barbiturates should be administered cautiously in patients with vitamin D deficiency.
