Disease interactions
24 potential interactions Applies to: 20 conditions, including Depression, Weight Loss, Seizures, Psychosis, and Myasthenia Gravis.
Acute Alcohol Intoxication
Major:
temazepam
Temazepam has a major potential interaction with Acute Alcohol Intoxication.
The use of benzodiazepines with alcohol is not recommended. Patients with acute alcohol intoxication exhibit depressed vital signs. The central nervous system depressant effects of benzodiazepines may be additive with those of alcohol, and severe respiratory depression and death may occur. Therapy with benzodiazepines should be administered cautiously in patients who might be prone to acute alcohol intake.
Asphyxia
Major:
temazepam
Temazepam has a major potential interaction with Asphyxia.
Benzodiazepines may cause respiratory depression and apnea, usually when given in high dosages and/or by intravenous administration. 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 benzodiazepines 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. Benzodiazepines, especially injectable formulations, should generally be avoided in patients with sleep apnea, severe respiratory insufficiency, or hypoxia.
Central Nervous System Disorders
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Central Nervous System Disorders.
Tolterodine is associated with anticholinergic central nervous system (CNS) effects. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. Tolterodine should be used with caution in patients with Parkinson's disease and in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms.
Dementia
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Dementia.
Tolterodine is associated with anticholinergic central nervous system (CNS) effects. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. Tolterodine should be used with caution in patients with Parkinson's disease and in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms.
Depression
Moderate:
temazepam
Temazepam has a moderate potential interaction with Depression.
Benzodiazepines depress the central nervous system and may cause or exacerbate mental depression and cause suicidal behavior and ideation. Episodes of mania and hypomania have also been reported in depressed patients treated with some of these agents. Therapy with benzodiazepines should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Drug Dependence
Major:
temazepam
Temazepam has a major potential interaction with Drug Dependence.
Benzodiazepines have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use and/or excessive dosages. However, abrupt cessation following continual use of as few as 6 weeks at therapeutic levels has occasionally precipitated withdrawal symptoms. Addiction- prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance when treated with benzodiazepines. 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 benzodiazepine therapy should be undertaken gradually using a dosage- tapering schedule. If withdrawal symptoms occur, temporary reinstitution of benzodiazepines may be necessary.
Gastrointestinal Obstruction
Major:
tolterodine
Tolterodine has a major potential interaction with Gastrointestinal Obstruction.
The use of tolterodine is contraindicated in patients with GI obstruction, ileus, or obstructive uropathy. Tolterodine exerts anticholinergic activity by competitive antagonism of muscarinic receptors.
Glaucoma/Intraocular Hypertension
Major:
temazepam
Temazepam has a major potential interaction with Glaucoma/Intraocular Hypertension.
The manufacturers consider the use of benzodiazepines to be contraindicated in patients with acute angle-closure glaucoma or untreated open-angle glaucoma. These agents do not possess anticholinergic activity but have very rarely been associated with increased intraocular pressure.
Major:
tolterodine
Tolterodine has a major potential interaction with Glaucoma/Intraocular Hypertension.
The use of tolterodine is contraindicated in patients with uncontrolled angle-closure (narrow angle) glaucoma. Tolterodine exerts anticholinergic activity and can result in increased intraocular pressure and loss of accommodation.
Hyperkinetic Syndrome of Childhood
Moderate:
temazepam
Temazepam has a moderate potential interaction with Hyperkinetic Syndrome of Childhood.
Paradoxical reactions, including excitability, irritability, aggressive behavior, agitation, nervousness, hostility, anxiety, sleep disturbances, nightmares and vivid dreams, have been reported with the use of benzodiazepines in psychiatric patients and pediatric patients with hyperactive aggressive disorders. Such patients should be monitored for signs of paradoxical stimulation during therapy with benzodiazepines. The manufacturers do not recommend the use of benzodiazepines for the treatment of psychosis.
Liver Disease
Moderate:
temazepam
Temazepam has a moderate potential interaction with Liver Disease.
Benzodiazepines are metabolized by the liver and undergo oxidative N-dealkylation to active metabolites that are substantially longer-acting than the parent compound. These metabolites then undergo further biotransformation before excretion by the kidney. Therapy with benzodiazepines should be administered cautiously at lower initial dosages in patients with impaired hepatic function. Agents that are converted to weakly active, short-acting, or inactive metabolites (such as oxazepam and temazepam) may be preferable in patients with hepatic impairment.
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Liver Disease.
Tolterodine undergoes biotransformation in the liver of extensive metabolizers to an active metabolite. Poor metabolizers have a greater concentration of active parent and less active metabolite, however the net activity of tolterodine is expected to be the same. The pharmacokinetic disposition of tolterodine can be significantly altered in patients with hepatic dysfunction. Therapy with tolterodine should be administered cautiously in patients with severe hepatic impairment and dosage should be reduced to no greater than 1 mg twice daily.
Long QT Syndrome
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Long QT Syndrome.
Tolterodine has been associated with QT prolongation. The effect on QT interval correlates with plasma concentration of tolterodine. Caution is recommended when prescribing this agent to patients with a known history of QT prolongation or to patients who are taking Class IA (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol) antiarrhythmic medications.
Myasthenia Gravis
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Myasthenia Gravis.
Tolterodine acts as a competitive antagonist of acetylcholine at postganglionic muscarinic receptors. Caution is recommended when using this agent in patients with myasthenia gravis, a disease characterized by decreased cholinergic activity at the neuromuscular junction.
Psychosis
Moderate:
temazepam
Temazepam has a moderate potential interaction with Psychosis.
Benzodiazepines depress the central nervous system and may cause or exacerbate mental depression and cause suicidal behavior and ideation. Episodes of mania and hypomania have also been reported in depressed patients treated with some of these agents. Therapy with benzodiazepines should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
temazepam
Temazepam has a moderate potential interaction with Psychosis.
Paradoxical reactions, including excitability, irritability, aggressive behavior, agitation, nervousness, hostility, anxiety, sleep disturbances, nightmares and vivid dreams, have been reported with the use of benzodiazepines in psychiatric patients and pediatric patients with hyperactive aggressive disorders. Such patients should be monitored for signs of paradoxical stimulation during therapy with benzodiazepines. The manufacturers do not recommend the use of benzodiazepines for the treatment of psychosis.
Pulmonary Impairment
Major:
temazepam
Temazepam has a major potential interaction with Pulmonary Impairment.
Benzodiazepines may cause respiratory depression and apnea, usually when given in high dosages and/or by intravenous administration. 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 benzodiazepines 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. Benzodiazepines, especially injectable formulations, should generally be avoided in patients with sleep apnea, severe respiratory insufficiency, or hypoxia.
Renal Dysfunction
Moderate:
temazepam
Temazepam has a moderate potential interaction with Renal Dysfunction.
Benzodiazepines are excreted by the kidneys and should be used with caution in patients with impaired renal function and end-stage kidney disease.
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Renal Dysfunction.
The renal elimination of tolterodine and active metabolite is limited and a prolonged half-life is not anticipated in patients with renal impairment. However, the pharmacokinetic disposition of tolterodine has not been evaluated in patients with renal impairment and it is recommended that tolterodine be administered cautiously in patients with compromised renal function.
Respiratory Arrest
Major:
temazepam
Temazepam has a major potential interaction with Respiratory Arrest.
Benzodiazepines may cause respiratory depression and apnea, usually when given in high dosages and/or by intravenous administration. 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 benzodiazepines 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. Benzodiazepines, especially injectable formulations, should generally be avoided in patients with sleep apnea, severe respiratory insufficiency, or hypoxia.
Seizures
Major:
temazepam
Temazepam has a major potential interaction with Seizures.
The use of benzodiazepines in patients with seizure disorders may increase the incidence or precipitate the onset of generalized tonic-clonic seizures (grand mal). Appropriate anticonvulsant medication might need to be initiated or the dosage increased. Abrupt cessation of benzodiazepine therapy may precipitate seizures and other withdrawal symptoms, particularly after prolonged use and/or excessive dosages. Status epilepticus may occur in patients with a history of seizures withdrawn rapidly from benzodiazepine therapy. Following chronic administration, cessation of benzodiazepine therapy should occur gradually with incrementally reduced dosages. Patients should be advised not to discontinue medication without first consulting with the physician.
Sleep Disorders
Moderate:
temazepam
Temazepam has a moderate potential interaction with Sleep Disorders.
Sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder. The symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient. The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric or medical illness that should be evaluated. Worsening of insomnia with the emergence of new thinking or behavior abnormalities may be the consequence of an unrecognized disorder.
Urinary Retention
Major:
tolterodine
Tolterodine has a major potential interaction with Urinary Retention.
The use of tolterodine is contraindicated in patients with GI obstruction, ileus, or obstructive uropathy. Tolterodine exerts anticholinergic activity by competitive antagonism of muscarinic receptors.
Weight Loss
Moderate:
temazepam
Temazepam has a moderate potential interaction with Weight Loss.
The plasma half-lives of benzodiazepines may be prolonged in obese patients, presumably due to increased distribution into fat. Marked increases in distribution (> 100%) have been reported for diazepam and midazolam, and moderate increases (25% to 100%) for alprazolam, lorazepam, and oxazepam. Therapy with benzodiazepines should be administered cautiously in obese patients, with careful monitoring of CNS status. Longer dosing intervals may be appropriate. When dosing by weight, loading doses should be based on actual body weight, while maintenance dose should be based on ideal body weight to avoid toxicity.
