Can you take Guanfacine with Singulair?

guanFACINE has a moderate potential interaction with Cerebrovascular Insufficiency.

Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system, resulting in decreases in heart rate, peripheral and renovascular resistance, and blood pressure. Therapy with these agents should be administered cautiously in patients with hypotension or conditions that may be exacerbated by decreased blood pressure and perfusion, such as coronary insufficiency, peripheral vascular disease (e.g., Raynaud's syndrome), cerebrovascular disease, or recent myocardial infarction.

The montelukast in Singulair has a major potential interaction with Depression.

The use of montelukast is associated with neuropsychiatric events. Patients and prescribers should be alert for neuropsychiatric events. Care should be taken before using this agent in patients with any history of mental illness. If neuropsychiatric events occur during treatment, it is recommended to carefully evaluate the risks and benefits of continuing treatment with montelukast.

guanFACINE has a moderate potential interaction with Depression.

Central alpha-2 adrenoreceptor agonists may occasionally cause mental depression and should be used cautiously in patients with a history of depression.

guanFACINE has a moderate potential interaction with Heart Block.

Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system. Heart rate is decreased, which may lead to or exacerbate sinus bradycardia and atrioventricular block. Therapy with central alpha-2 adrenoreceptor agonists should be administered cautiously in patients with conduction disturbances such as sinus node dysfunction or AV nodal disease.

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

The safety and effectiveness of guanfacine in children under 12 years of age has not been demonstrated and its use in this age group is not recommended. However, there have been some spontaneous postmarketing reports of mania and aggressive behavioral changes in pediatric patients with attention- deficit hyperactivity disorder (ADHD) that received this drug. All patients had medical or family risks of bipolar disorder, and all of them recovered after treatment discontinuation. Hallucinations have also been reported in pediatric patients receiving guanfacine for the treatment of ADHD.

guanFACINE has a moderate potential interaction with Hypotension.

Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system, resulting in decreases in heart rate, peripheral and renovascular resistance, and blood pressure. Therapy with these agents should be administered cautiously in patients with hypotension or conditions that may be exacerbated by decreased blood pressure and perfusion, such as coronary insufficiency, peripheral vascular disease (e.g., Raynaud's syndrome), cerebrovascular disease, or recent myocardial infarction.

guanFACINE has a moderate potential interaction with Ischemic Heart Disease.

Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system, resulting in decreases in heart rate, peripheral and renovascular resistance, and blood pressure. Therapy with these agents should be administered cautiously in patients with hypotension or conditions that may be exacerbated by decreased blood pressure and perfusion, such as coronary insufficiency, peripheral vascular disease (e.g., Raynaud's syndrome), cerebrovascular disease, or recent myocardial infarction.

guanFACINE has a moderate potential interaction with Liver Disease.

Normally, approximately 50% of a guanfacine dose is eliminated unchanged by the kidney and the rest metabolized by the liver. However, neither the parent drug nor its metabolites accumulate significantly during chronic dosing in patients with severe renal impairment due to increased hepatic metabolism of the drug in these patients. Thus, initial dosage adjustments are generally not necessary in renal impairment. Dosage titration, however, should be made cautiously if hepatic function is also compromised. The pharmacokinetics of guanfacine has not been studied in patients with liver disease. The manufacturer recommends caution when the drug is used in such patients.

The montelukast in Singulair has a moderate potential interaction with Liver Disease.

Reports of cholestatic hepatitis, hepatocellular liver-injury, and mixed-pattern liver injury have been reported in patients treated with montelukast sodium that had underlying potential for liver disease, such as alcohol use or other forms of hepatitis. Patients with mild-to-moderate hepatic insufficiency and clinical evidence of cirrhosis had evidence of decreased metabolism of montelukast. No dosage adjustment is required in patients with mild-to-moderate hepatic insufficiency. The pharmacokinetics of montelukast sodium in patients with more severe hepatic impairment or with hepatitis have not been evaluated. Use caution when prescribing montelukast to these patients.

The montelukast in Singulair has a major potential interaction with Neurotic Depression.

The use of montelukast is associated with neuropsychiatric events. Patients and prescribers should be alert for neuropsychiatric events. Care should be taken before using this agent in patients with any history of mental illness. If neuropsychiatric events occur during treatment, it is recommended to carefully evaluate the risks and benefits of continuing treatment with montelukast.

guanFACINE has a moderate potential interaction with Peripheral Arterial Disease.

Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system, resulting in decreases in heart rate, peripheral and renovascular resistance, and blood pressure. Therapy with these agents should be administered cautiously in patients with hypotension or conditions that may be exacerbated by decreased blood pressure and perfusion, such as coronary insufficiency, peripheral vascular disease (e.g., Raynaud's syndrome), cerebrovascular disease, or recent myocardial infarction.

The montelukast in Singulair has a moderate potential interaction with Phenylketonuria.

Singulair (brand of montelukast) chewable tablets contain 0.842 mg of phenylalanine per each 5 mg tablet. The phenylalanine content should be considered when this product is used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics).

The montelukast in Singulair has a major potential interaction with Psychosis.

The use of montelukast is associated with neuropsychiatric events. Patients and prescribers should be alert for neuropsychiatric events. Care should be taken before using this agent in patients with any history of mental illness. If neuropsychiatric events occur during treatment, it is recommended to carefully evaluate the risks and benefits of continuing treatment with montelukast.

The montelukast in Singulair has a moderate potential interaction with Pulmonary Impairment.

Patients with asthma on therapy with montelukast may present with systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome, a condition which is often treated with systemic corticosteroid therapy. Prescribers should be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients. Care should be taken before using this agent in patients with history of pulmonary disorders.

guanFACINE has a moderate potential interaction with Renal Dysfunction.

Normally, approximately 50% of a guanfacine dose is eliminated unchanged by the kidney and the rest metabolized by the liver. However, neither the parent drug nor its metabolites accumulate significantly during chronic dosing in patients with severe renal impairment due to increased hepatic metabolism of the drug in these patients. Thus, initial dosage adjustments are generally not necessary in renal impairment. Dosage titration, however, should be made cautiously if hepatic function is also compromised. The pharmacokinetics of guanfacine has not been studied in patients with liver disease. The manufacturer recommends caution when the drug is used in such patients.

guanFACINE has a moderate potential interaction with Sinus Node Dysfunction.

Central alpha-2 adrenoreceptor agonists reduce sympathetic outflow from the central nervous system. Heart rate is decreased, which may lead to or exacerbate sinus bradycardia and atrioventricular block. Therapy with central alpha-2 adrenoreceptor agonists should be administered cautiously in patients with conduction disturbances such as sinus node dysfunction or AV nodal disease.
