Neurontin Disease Interactions

There are 4 disease interactions with Neurontin (gabapentin).


Anxiolytics/sedatives/hypnotics (applies to Neurontin) drug dependence

Major Potential Hazard, Moderate plausibility. Applicable conditions: Drug Abuse/Dependence

Anxiolytic, sedative, and hypnotic agents have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use of excessive dosages, and abrupt cessation and/or a reduction in dosage may precipitate withdrawal symptoms. In patients who have developed tolerance, overdosage can still produce respiratory depression and death. Therapy with anxiolytic, sedative, and hypnotic agents should be administered cautiously and for as brief a period as possible. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with these agents. In addition, it may be prudent to refrain from dispensing large quantities of medication to such patients. After prolonged use or if dependency is suspected, withdrawal of medication should be undertaken gradually using a dosage-tapering schedule.

Gabapentin (applies to Neurontin) renal dysfunction

Major Potential Hazard, High plausibility.

Gabapentin is primarily eliminated unchanged by the kidney. Therapy with gabapentin should be administered cautiously in patients with impaired renal function. Dosage adjustments and titration should be made in accordance with product package labeling and individual patient response.

Antiepileptics (applies to Neurontin) suicidal tendency

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Depression, Psychosis

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

Gabapentin (applies to Neurontin) hemodialysis

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.
