Interactions between your drugs

Moderate

citalopram amifampridine

Applies to: Celexa (citalopram) and amifampridine

MONITOR: The use of amifampridine is associated with a dose-related risk of seizures, and the risk may be further increased when coadministered with other drugs that can reduce the seizure threshold such as antidepressants, antimalarials, neuroleptics, phenothiazines, and quinolones. Seizures have occurred in patients without a history of seizures taking amifampridine at recommended dosages and at various times after initiation of treatment. Reported incidence is approximately 2%. Many of the patients were taking medications or had comorbid medical conditions that may have lowered the seizure threshold.

MANAGEMENT: Caution is advised if amifampridine is coadministered with any substance that can reduce the seizure threshold, particularly in the elderly and in patients with other risk factors for seizures (e.g., head trauma; brain tumor; severe hepatic cirrhosis; metabolic disorders; CNS infections; excessive use of alcohol or sedatives; addiction to opiates, cocaine, or stimulants; diabetes treated with oral hypoglycemic agents or insulin). Consider discontinuation or dose reduction of amifampridine in patients who experience a seizure during treatment. Use of amifampridine is contraindicated in patients with a history of seizures.

Drug and food interactions

Moderate

citalopram food

Applies to: Celexa (citalopram)

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.

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.
