Interactions between your drugs

Major

methylene blue ZOLMitriptan

Applies to: Hyophen (benzoic acid / hyoscyamine / methenamine / methylene blue / phenyl salicylate) and zolmitriptan

CONTRAINDICATED: Monoamine oxidase inhibitors (MAOIs) may significantly elevate the plasma concentrations of certain 5-HT1 receptor agonists (namely rizatriptan, sumatriptan, and zolmitriptan) and their active metabolites by inhibiting their metabolic clearance via monoamine oxidase, subtype A. Clinically, this interaction may increase the risk of vasospastic reactions, including coronary artery vasospasm, peripheral vascular ischemia and colonic ischemia, associated with the use of 5-HT1 receptor agonists. Although the pharmacokinetic alterations are observed only with a limited number of 5-HT1 receptor agonists and their metabolites, the possibility of a pharmacodynamic interaction should be considered for all agents in the class, since they exhibit modest 5-HT1A activity. Theoretically, MAOIs may potentiate the serotonergic activity of these agents and increase the risk of serotonin syndrome, which is a rare but serious and potentially fatal condition thought to result from hyperstimulation of brainstem 5-HT1A and 2A receptors. The mechanism is inhibition of the breakdown of serotonin by MAOIs. Symptoms of the serotonin syndrome may include mental status changes such as irritability, altered consciousness, confusion, hallucinations, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, blood pressure lability, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea.

MANAGEMENT: Concomitant use of rizatriptan, sumatriptan, or zolmitriptan with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, linezolid, methylene blue, procarbazine) is considered contraindicated. At least 14 days should elapse between discontinuation of MAOI therapy and initiation of treatment with 5-HT1 receptor agonists. If concurrent therapy is necessary, almotriptan, frovatriptan and naratriptan may be preferred due to the lack of a significant pharmacokinetic interaction with MAOIs. However, patients should be closely monitored for adverse effects related to excessive serotonergic activity.

Drug and food interactions

Moderate

ZOLMitriptan food

Applies to: zolmitriptan

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled 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.

Moderate

hyoscyamine food

Applies to: Hyophen (benzoic acid / hyoscyamine / methenamine / methylene blue / phenyl salicylate)

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
