Drug Interactions between clonazepam and Urogesic Blue
This report displays the potential drug interactions for the following 2 drugs:
- clonazepam
- Urogesic Blue (hyoscyamine/methenamine/methylene blue/sodium biphosphate)
Interactions between your drugs
clonazePAM methylene blue
Applies to: clonazepam and Urogesic Blue (hyoscyamine / methenamine / methylene blue / sodium biphosphate)
MONITOR: Limited clinical data suggest that concomitant use of clonazepam with monoamine oxidase inhibitors (MAOIs) may precipitate a hypertensive and/or flushing reaction. The mechanism of interaction has not been established. Phenelzine has been specifically implicated. Data for other combinations of MAOIs and benzodiazepines are not available.
MANAGEMENT: Until more information is available, patients should be monitored for development of hypertension during coadministration of clonazepam with an MAOI or or other agents that possess MAOI activity such as furazolidone, linezolid, methylene blue, and procarbazine. Patients should be advised to notify their physician if they develop severe headaches or flushing.

Drug and food interactions
sodium biphosphate food
Applies to: Urogesic Blue (hyoscyamine / methenamine / methylene blue / sodium biphosphate)
ADJUST DOSING INTERVAL: Bowel cleansing products can increase the gastrointestinal transit rate. Oral medications administered within one hour of the start of administration of the bowel cleansing solution may be flushed from the gastrointestinal tract and not properly absorbed.
MANAGEMENT: Patients should be advised that absorption of oral medications may be impaired during bowel cleansing treatment. Oral medications (e.g., anticonvulsants, oral contraceptives, antidiabetic agents, antibiotics) should not be administered during and within one hour of starting bowel cleansing treatment whenever possible. However, if concomitant use cannot be avoided, monitoring for reduced therapeutic effects may be advisable.

clonazePAM food
Applies to: clonazepam
GENERALLY AVOID: Acute ethanol ingestion may potentiate the CNS effects of many benzodiazepines. Tolerance may develop with chronic ethanol use. The mechanism may be decreased clearance of the benzodiazepines because of CYP450 hepatic enzyme inhibition. Also, it has been suggested that the cognitive deficits induced by benzodiazepines may be increased in patients who chronically consume large amounts of alcohol.
MANAGEMENT: Patients should be advised to avoid alcohol during benzodiazepine therapy.

hyoscyamine food
Applies to: Urogesic Blue (hyoscyamine / methenamine / methylene blue / sodium biphosphate)
GENERALLY AVOID: Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous. In addition, the potential for abuse may be increased with the combination. The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system. No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load. However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.
MANAGEMENT: Alcohol should generally be avoided during therapy with anticholinergic agents. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.
