Disease interactions
33 potential interactionsApplies to: 25 conditions, including High Blood Pressure, Depression, Anxiety and Stress, Asthma, and COPD.
Alcoholism
Major:lisdexamfetamine
Lisdexamfetamine has a major potential interaction with Alcoholism.
CNS stimulants (especially amphetamines) have a high potential for abuse and misuse, which can lead to development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants can result in overdose and death; this risk is increased with higher doses or unapproved methods of administration (e.g., snorting, injection). Before prescribing a CNS stimulant, each patient's risk for abuse, misuse, and addiction should be assessed. Throughout therapy, it is recommended to reassess each patient's risk and frequently monitor for signs/symptoms of abuse, misuse, and addiction. Therapy with CNS stimulants should be administered cautiously, if at all, in patients with a history of alcohol or substance abuse. The use of some agents is contraindicated in patients with a history of drug abuse.
Anxiety and Stress
Major:lisdexamfetamine
Lisdexamfetamine has a major potential interaction with Anxiety and Stress.
Some CNS stimulants are contraindicated in patients with marked agitation and/or anxiety since these symptoms may be aggravated. CNS stimulants may also exacerbate symptoms of behavior disturbance and thought disorder in psychotic patients, particularly children. Therapy with CNS stimulants should be administered cautiously in patients with a history of psychosis or a predisposition to agitated states.
Asthma
Moderate:dextromethorphan / triprolidine
The triprolidine in dextromethorphan / triprolidine has a moderate potential interaction with Asthma.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Cardiovascular Conditions and Disorders
Major:lisdexamfetamine
Lisdexamfetamine has a major potential interaction with Cardiovascular Conditions and Disorders.
Many amphetamines and amphetamine-like drugs are contraindicated in patients with advanced arteriosclerosis, symptomatic or unstable cardiac or cerebrovascular disease, moderate to severe hypertension, or hyperthyroidism. Like other sympathomimetic amines, amphetamines may cause cardiovascular adverse effects such as palpitation, tachycardia, cardiac arrhythmias, and elevation of blood pressure. Rarely, cardiomyopathy manifested as ventricular hypertrophy and/or congestive heart failure has been reported during chronic amphetamine use. In addition, sudden death has been reported in association with amphetamine therapy at usual dosages in children with structural cardiac abnormalities. In general, amphetamines should not be used in patients with structural cardiac abnormalities. If not otherwise contraindicated, therapy with amphetamines should be administered cautiously in patients with a current or past history of cardiovascular or cerebrovascular disease.
Moderate:dextromethorphan / triprolidine
The triprolidine in dextromethorphan / triprolidine has a moderate potential interaction with Cardiovascular Conditions and Disorders.
Antihistamines may infrequently cause cardiovascular adverse effects related to their anticholinergic and local anesthetic (quinidine-like) activities. Tachycardia, palpitation, ECG changes, arrhythmias, hypotension, and hypertension have been reported. Although these effects are uncommon and usually limited to overdosage situations, the manufacturers and some clinicians recommend that therapy with antihistamines be administered cautiously in patients with cardiovascular disease, hypertension, and/or hyperthyroidism.
Cerebral Vascular Disorder
Major:lisdexamfetamine
Lisdexamfetamine has a major potential interaction with Cerebral Vascular Disorder.
Many amphetamines and amphetamine-like drugs are contraindicated in patients with advanced arteriosclerosis, symptomatic or unstable cardiac or cerebrovascular disease, moderate to severe hypertension, or hyperthyroidism. Like other sympathomimetic amines, amphetamines may cause cardiovascular adverse effects such as palpitation, tachycardia, cardiac arrhythmias, and elevation of blood pressure. Rarely, cardiomyopathy manifested as ventricular hypertrophy and/or congestive heart failure has been reported during chronic amphetamine use. In addition, sudden death has been reported in association with amphetamine therapy at usual dosages in children with structural cardiac abnormalities. In general, amphetamines should not be used in patients with structural cardiac abnormalities. If not otherwise contraindicated, therapy with amphetamines should be administered cautiously in patients with a current or past history of cardiovascular or cerebrovascular disease.
COPD
Moderate:dextromethorphan / triprolidine
The triprolidine in dextromethorphan / triprolidine has a moderate potential interaction with COPD.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Depression
Major:lisdexamfetamine
Lisdexamfetamine has a major potential interaction with Depression.
The use of CNS stimulants can cause psychotic symptoms, suicidal ideation, and aggression, and can exacerbate symptoms of behavior disturbance and thought disorder; CNS stimulants may induce a manic or mixed episode in patients with bipolar disorder. Psychiatric symptoms have been reported in patients with and without history of psychiatric disorders. All patients (particularly those with psychotic or bipolar disorders) should be monitored closely, especially during treatment initiation and at times of dose changes. Extreme caution should be exercised when CNS stimulants are given to patients with a history of psychosis, depression, mania, or bipolar disorder. Prior to initiating therapy, all patients should be screened for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or family history of suicide, bipolar disease, or depression). If any psychiatric symptoms emerge or are exacerbated, treatment suspension should be considered. Some CNS stimulants are contraindicated in patients with marked agitation or anxiety.
Drug Dependence
Major:lisdexamfetamine
Lisdexamfetamine has a major potential interaction with Drug Dependence.
CNS stimulants (especially amphetamines) have a high potential for abuse and misuse, which can lead to development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants can result in overdose and death; this risk is increased with higher doses or unapproved methods of administration (e.g., snorting, injection).

Gastrointestinal Obstruction
Moderate:dextromethorphan / triprolidine
The triprolidine in dextromethorphan / triprolidine has a moderate potential interaction with Gastrointestinal Obstruction.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects. In contrast, the newer, relatively nonsedating antihistamines (e.g., cetirizine, fexofenadine, loratadine) reportedly have low to minimal anticholinergic activity at normally recommended dosages and may be appropriate alternatives.
Glaucoma/Intraocular Hypertension
Major:lisdexamfetamine
Lisdexamfetamine has a major potential interaction with Glaucoma/Intraocular Hypertension.
Some amphetamines and amphetamine-like drugs are contraindicated in patients with narrow-angle glaucoma or anatomically narrow angles. Like other sympathomimetic amines, amphetamines can induce transient mydriasis. In patients with narrow angles, pupillary dilation can provoke an acute attack of angle-closure glaucoma. If possible, these agents should also be avoided in patients with other forms of glaucoma since mydriasis may occasionally increase intraocular pressure.
Moderate:dextromethorphan / triprolidine
