Interactions between Orabase and Singulair

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.

The benzocaine topical in Orabase has a moderate potential interaction with G-6-PD Deficiency.

Rarely, benzocaine has induced methemoglobinemia resulting in respiratory distress and cyanosis. Therapy with benzocaine should be administered cautiously to patients with or predisposed to methemoglobinemia. If life-threatening or severe methemoglobinemia develops, methylene blue infused at a dosage of 1 to 2 mg/kg body weight will rapidly reverse or improve the condition except in G-6-PD-deficient 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 benzocaine topical in Orabase has a moderate potential interaction with Methemoglobinemia.

Rarely, benzocaine has induced methemoglobinemia resulting in respiratory distress and cyanosis. Therapy with benzocaine should be administered cautiously to patients with or predisposed to methemoglobinemia. If life-threatening or severe methemoglobinemia develops, methylene blue infused at a dosage of 1 to 2 mg/kg body weight will rapidly reverse or improve the condition except in G-6-PD-deficient 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.

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.
