Amantadine Disease Interactions

There are 7 disease interactions with amantadine.

Major

Amantadine (applies to amantadine) psychoses/depression

Major Potential Hazard, Moderate plausibility. Applicable conditions: Psychosis, History - Psychiatric Disorder, Alcoholism, Drug Abuse/Dependence

Amantadine may precipitate or exacerbate psychotic symptoms. Rarely, suicide attempts and suicidal ideation have also been reported, some of which occurred in patients with no prior history of psychiatric illness who were taking short courses of amantadine for influenza. Therapy with amantadine should be administered cautiously in patients with a history of psychiatric disorders, emotional instability, or substance abuse, and particularly if they are elderly. It may be prudent to refrain from dispensing large quantities of amantadine to these patients to prevent intentional overdose, which is potentially fatal.

Major

Amantadine (applies to amantadine) renal dysfunction

Major Potential Hazard, High plausibility.

Amantadine is primarily eliminated by the kidney. Patients with renal impairment may be at greater risk for adverse effects from amantadine due to decreased drug clearance. Therapy with amantadine should be administered cautiously in patients with renal impairment. Dosage adjustments are recommended for patients with moderate to severe renal dysfunction.

Major

Amantadine (applies to amantadine) seizure disorders

Major Potential Hazard, Moderate plausibility. Applicable conditions: Seizures

Amantadine may rarely precipitate or exacerbate seizure activity. Patients with epilepsy or predisposed to seizures should be monitored closely for increased seizure activity during therapy with amantadine.

Major

Dopamine agonists (applies to amantadine) hypotension

Major Potential Hazard, Moderate plausibility.

Dopamine agonists may impair the systemic regulation of blood pressure, with resultant orthostatic hypotension, especially during dose escalation. Therapy with dopamine agonists should be monitored carefully in patients with Parkinson's disease since they may have an impaired ability to respond to an orthostatic challenge, and also in patients receiving antihypertensive drugs.

Major

Dopaminergic antiparkinson agents (applies to amantadine) psychosis

Major Potential Hazard, Moderate plausibility.

Ordinarily, patients with major psychotic disorder should not be treated with dopaminergic antiparkinson agents, because of the risk of exacerbating psychosis. Hallucinations and psychotic-like behavior have been reported with dopaminergic medications. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson's disease and may decrease the effectiveness of these drugs.

Moderate

Amantadine (applies to amantadine) CHF/edema

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Congestive Heart Failure, Fluid Retention

Amantadine may occasionally cause peripheral edema and, rarely, congestive heart failure. Patients with edema or congestive heart failure should be monitored closely for exacerbation of their condition. Dosage adjustments may be necessary.

Amantadine (applies to amantadine) hypotension

Moderate Potential Hazard, Moderate plausibility.

Amantadine may occasionally cause orthostatic hypotension. Patients with hypotension should be monitored for exacerbation of their condition during therapy with amantadine. Dosage adjustments may be necessary, and patients should be advised not to rise abruptly from a sitting or recumbent position.

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.
