Atomoxetine Hydrochloride interactions

Conditions

Conditions in which Atomoxetine Hydrochloride needs care, as documented in this source.

• Glaucoma

  Major

  The use of most CNS stimulants is contraindicated in patients with glaucoma, as these agents exhibit sympathomimetic activity and may induce mydriasis provoking an increase in intraocular pressure.

• Heart Diseases

  Major

  The use of CNS stimulants is 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 adults and children taking CNS stimulant treatment. 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.

  Major

  CNS stimulant medications have shown to increase blood pressure, and their use might be contraindicated in patients with severe hypertension. Caution should be used when administering to patients with preexisting high blood pressure and other cardiovascular conditions. All patients under treatment should be regularly monitored for changes in blood pressure and heart rate.

• Liver Diseases

  Major

  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. Additionally, postmarketing reports have shown that atomoxetine can cause severe liver injury. Laboratory testing should be done at the first sign or symptom of liver dysfunction (jaundice, dark urine, upper quadrant tenderness) and treatment should be discontinued in patients with evidence of liver injury.

• Mental Disorders

  Major

  The use of CNS stimulants can cause psychotic or maniac symptoms, suicidal ideation, aggression and can exacerbate symptoms of behavior disturbance and thought disorder. Psychiatric symptoms have been reported in patients with and without history of psychiatric disorders, and all patients should be monitored closely, specially 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. All patients receiving treatment should be screened for bipolar disease prior to initiation. If any psychiatric symptoms emerge or are exacerbated, treatment suspension should be considered. CNS stimulants are contraindicated in patients with marked agitation or anxiety.

• Bipolar Disorder

  Moderate

  Central nervous system (CNS) stimulants may induce a mixed/manic episode in patients with bipolar disorder. Prior to initiating treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or a family history of suicide, bipolar disorder, and depression). Close monitoring is recommended when using these agents in patients with bipolar disorders.

• Epilepsy

  Moderate

  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 prior history of seizures or EEG abnormalities, and very rarely in patients with no previous history of seizures. Therapy with CNS stimulants should be used with caution in patients with or predisposed to seizures. If seizures appear, therapy should be discontinued.
