Monitor
Coadministration of two or more sympathomimetic or noradrenergic agents may increase the risk of nervousness, irritability, tachycardia, and/or increased blood pressure. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic and/or noradrenergic agents, including norepinephrine transporter inhibitors. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.
Management
Caution is advised if two or more sympathomimetic or noradrenergic agents are coadministered. Pulse and blood pressure should be closely monitored. Consultation with individual product labeling, as well as relevant institutional protocols, may be advisable for further guidance.

Generally avoid
Alcohol may potentiate the central nervous system and cardiovascular effects of centrally-acting appetite suppressants. In one study, concurrent administration of methamphetamine (30 mg intravenously) and ethanol (1 gm/kg orally over 30 minutes) increased heart rate by 24 beats/minute compared to methamphetamine alone. This increases cardiac work and myocardial oxygen consumption, which may lead to more adverse cardiovascular effects than either agent alone. Subjective effects of ethanol were diminished in the eight study subjects, but those of methamphetamine were not affected. The pharmacokinetics of methamphetamine were also unaffected except for a decrease in the apparent volume of distribution at steady state.
Management
Concomitant use of centrally-acting appetite suppressants and alcohol should be avoided if possible, especially in patients with a history of cardiovascular disease. Patients should be counselled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Disease interactions
31 potential interactions Applies to: 23 conditions, including High Blood Pressure, Depression, Type 2 Diabetes, Anxiety and Stress, and Seizures.
Alcoholism
Major:
mazindol
Mazindol 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:
mazindol
Mazindol 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.
Cardiovascular Conditions and Disorders
Major:
mazindol
Mazindol 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.
Cerebral Vascular Disorder

Depression
Major:
mazindol
Mazindol 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.
Diabetes Mellitus
Moderate:
S2 Inhalant
The racepinephrine in S2 Inhalant has a moderate potential interaction with Diabetes Mellitus.
Adrenergic bronchodilators 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. Large doses of IV albuterol (not commercially available in the U.S.) and terbutaline sulfate have been reported to cause exacerbation of preexisting diabetes mellitus and ketoacidosis. Therapy with adrenergic bronchodilators should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate. Systemic adverse effects are minimized, but not abolished, by administration of these agents via oral inhalation.
Drug Dependence
Major:
mazindol
Mazindol 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). 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.
Glaucoma/Intraocular Hypertension
Major:
mazindol
Mazindol 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.
Heart Disease
Major:
mazindol
Mazindol has a major potential interaction with Heart Disease.
Many CNS stimulants are contraindicated in patients with significant cardiovascular impairment such as uncompensated heart failure, severe coronary disease, severe hypertension (including that associated with hyperthyroidism or pheochromocytoma), cardiac structural abnormalities, serious arrhythmias, etc. Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who are treated with CNS stimulants at the recommended dosages for attention deficit hyperactivity disorder; use of these agents should be avoided in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. Additionally, stroke, myocardial infarction, chest pain, syncope, arrhythmias, and other symptoms have been reported in adults under treatment. A careful assessment of the cardiovascular status should be done in patients being considered for treatment. This includes family history, physical exam, and further cardiac evaluation (EKG and echocardiogram). Patients who develop symptoms should have a detailed cardiac evaluation and if needed, treatment should be suspended.

Moderate:
S2 Inhalant
The racepinephrine in S2 Inhalant has a moderate potential interaction with Heart Disease.
Adrenergic bronchodilators can stimulate cardiovascular beta- 1 and beta- 2 receptors, resulting in adverse effects such as tachycardia, palpitation, peripheral vasodilation, blood pressure changes, and ECG changes (e.g., flattening of the T wave; prolongation of the QT interval; ST segment depression). Direct stimulation of cardiac tissues is mediated by beta- 1 receptors and thus less likely to occur with beta-2-selective agents such as albuterol. However, beta-2-selectivity is not absolute and can be lost with larger doses. High dosages of these agents have been associated with precipitation or aggravation of angina, myocardial ischemia, and cardiac arrhythmias. Therapy with adrenergic bronchodilators should be administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, and/or underlying cardiovascular disorders such as coronary insufficiency, cardiac arrhythmias, or hypertension. The recommended dosages should not be exceeded.
High Blood Pressure

Hypokalemia
Moderate:
S2 Inhalant
The racepinephrine in S2 Inhalant has a moderate potential interaction with Hypokalemia.
Adrenergic bronchodilators may cause decreases in serum potassium concentrations, primarily when given by nebulization or intravenous administration. Although this effect is usually transient and does not require supplementation, clinically significant hypokalemia may occur in some patients, with the potential to induce cardiovascular adverse effects. The relevance of these observations to oral or oral aerosol/powder for inhalation therapy is unknown. Therapy with adrenergic bronchodilators should be administered cautiously in patients with or predisposed to hypokalemia.
Liver Disease
Moderate:
mazindol
Mazindol has a moderate potential interaction with Liver Disease.
In general, CNS stimulants are extensively metabolized by the liver. Their plasma clearance may be decreased and their half-life prolonged in patients with impaired hepatic function. Therapy with CNS stimulants should be administered cautiously in patients with moderate to severe liver disease, and the dosage should be adjusted accordingly in certain agents. Additionally, postmarketing reports have shown that atomoxetine can cause severe liver injury; laboratory testing should be done at the first sign/symptom of liver dysfunction (jaundice, dark urine, upper quadrant tenderness) and treatment should be discontinued in patients with evidence of liver injury.
Neurosis
Major:

Due to general central nervous system stimulation, therapy with CNS stimulant drugs may cause seizures. These drugs may lower the convulsive threshold in patients with history of seizures, with prior electroencephalogram (EEG) abnormalities without seizures, and very rarely, without history of seizures and no prior EEG evidence of seizures. Therapy with CNS stimulants should be used with caution in patients with or predisposed to seizures. If seizures occur, therapy should be discontinued.
Moderate:
S2 Inhalant
The racepinephrine in S2 Inhalant has a moderate potential interaction with Seizures.
Adrenergic bronchodilators may cause CNS stimulation. Therapy with adrenergic bronchodilators should be administered cautiously in patients with seizure disorders. Systemic adverse effects are minimized, but not abolished, by administration of these agents via oral inhalation.
Tic Disorder
Major:
mazindol
Mazindol has a major potential interaction with Tic Disorder.
CNS stimulants have been reported to worsen Tourette's syndrome and exacerbate motor and verbal tics. Before initiating therapy, it is recommended to assess family history and clinically evaluate patients for tics or Tourette's syndrome. Therapy with CNS stimulants, if necessary, should be administered cautiously in patients with tic disorders or family history of Tourette's syndrome. The manufacturers of the CNS stimulants, methylphenidate (racemic) and dexmethylphenidate (the more pharmacologically active d-enantiomer), consider their use to be contraindicated in such patients.
Type 2 Diabetes
Moderate:
mazindol
Mazindol has a moderate potential interaction with Type 2 Diabetes.
Obese, type 2 diabetic patients who achieve weight loss may demonstrate improved metabolic control of their disease as a result of their reduced weight. Therefore, patients with type 2 diabetes mellitus should be monitored during weight-reduction therapy (or therapy that may be expected to induce significant weight loss as a secondary effect) for hypoglycemia and reduced need for oral hypoglycemic medication or insulin, and the dosages of these agents adjusted accordingly. Patients should be apprised of the risk of hypoglycemia and be alert to potential signs and symptoms such as headache, dizziness, drowsiness, nervousness, confusion, tremor, hunger, weakness, perspiration, and palpitation.
