Pregabalin Disease Interactions

There are 5 disease interactions with pregabalin:


Antiepileptics (Includes pregabalin) ↔ suicidal tendency

Moderate Potential Hazard, Moderate plausibility. Applies to: 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 across multiple indications in either monotherapy or adjunctive therapy for a median treatment duration of 12 weeks (up to a maximum of 24 weeks) showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. The estimated rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% for 16,029 placebo-treated patients, representing an increase of approximately one case for every 530 patients treated. There were four suicides in AED-treated patients and none in placebo-treated patients, although the number is too small to establish any causal relationship. The increased risk of suicidal thoughts or behavior was observed as early as one week after starting AEDs and persisted for the duration of treatment assessed. The risk did not vary substantially by age (5 to 100 years) in the clinical trials analyzed. Therapy with AEDs should be administered cautiously in patients with depression or other psychiatric disorders. 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. For clinically significant or persistent symptoms, a dosage reduction or treatment withdrawal should be considered. If patients have symptoms of suicidal ideation or behavior, treatment should be discontinued.


Pregabalin (Includes pregabalin) ↔ angioedema

Moderate Potential Hazard, Moderate plausibility. Applies to: Angioedema

Angioedema has been reported during pregabalin therapy, including reports of life-threatening angioedema with respiratory compromise requiring emergency treatment. Therapy with pregabalin should be administered cautiously in patients at risk of developing angioedema or those with a previous episode of angioedema.


Pregabalin (Includes pregabalin) ↔ creatine kinase elevations

Moderate Potential Hazard, Moderate plausibility. Applies to: Myopathy

The use of pregabalin has been associated with creatine kinase elevations. Use caution when treating patients with diagnosed of suspected myopathy or with significantly elevated creating kinase levels.


Pregabalin (Includes pregabalin) ↔ peripheral edema

Moderate Potential Hazard, Moderate plausibility. Applies to: Congestive Heart Failure

Pregabalin treatment may cause peripheral edema. There are limited data concerning the use of pregabalin in patients with congestive heart failure. Therapy with pregabalin should be administered cautiously in patients with New York Heart Association (NYHA) Class III or IV cardiac status.


Pregabalin (Includes pregabalin) ↔ PR interval prolongation

Moderate Potential Hazard, Moderate plausibility. Applies to: Heart Block, Abnormal Electrocardiogram

Pregabalin should be administered cautiously in patients with preexisting conduction abnormalities (e.g., marked first-degree AV block or second- or third-degree AV block), as it has been associated with PR interval prolongation. In a clinical trial, the mean PR interval increase was 3 to 6 msec with pregabalin at doses higher than or equal to 300 mg per day. This mean change difference was not associated with an increased risk of PR increase >=25% from baseline, an increased percentage of subjects with on-treatment PR >200 msec, or an increased risk of adverse reactions of second or third degree AV block. Subgroup analyses did not identify an increased risk of PR prolongation in patients with baseline PR prolongation or in patients taking other PR prolonging medications. However, these analyses cannot be considered definitive because of the limited number of patients in these categories.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
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 information available.

Do not stop taking any medications without consulting your healthcare provider.
