Genomind Drug Interaction Guide®
Help ensure patient safety by fine-tuning treatments with G-DIG®
How will your patient metabolize a certain drug? How will that drug interact with other drugs—and with certain lifestyle factors?
Now you can better predict before you prescribe medications and treatments.
Knowing how drugs might interact is important to patient safety and efficacy. Now there’s an easy way to know how they may interact with patient genotypes as well as with other drugs: G-DIG, the Genomind Drug Interaction Guide.
An enhancement to your Genecept Assay® testing
A complimentary addition for clinicians who use Genecept, G-DIG is a patient-specific tool designed to assist clinicians in checking CYP450 gene-drug AND drug-drug interactions when prescribing medications. G-DIG allows clinicians to:
- Choose from among the most commonly prescribed psychotropic and non-psychotropic medications to see how certain drugs might interact with the patient’s individual pharmacokinetic profile (gene-drug interactions)
- Evaluate how drugs that the patient is already taking or that are being considered may interact with each other (drug-drug interactions)
- Assess how smoking or drinking coffee can affect the patient’s specific drug metabolism
G-DIG offers clinicians an easy, manageable way to assess a patient’s gene-drug and drug-drug interactions
Assessing gene-drug AND drug-drug interactions can be labor-intensive and yield an overwhelming amount of information. Not with G-DIG. Simply log into the Genomind Clinician Portal to access G-DIG for each of your patients who have been tested with Genecept.
Do No Harm
The phenomenon known as phenoconversion occurs when an individual with a “Normal Metabolizer” genotype is converted into Poor Metabolizer (PM) status as a result of drugs or environmental factors. Monitoring only patient genotypes may miss about 20% of patients who actually have a PM phenotype (secondary to their drug regimen).1,2 Conversely, failing to assess a patient’s genotype may underestimate altered metabolism risk. Roughly 6% to 40% of people exist as poor metabolizers or ultra-rapid metabolizers, respectively, across populations.3-6

G-DIG allows you to explore interactions among the most-prescribed drugs, including:
Exclusive to G-DIG: environmental modifiers
In addition to allowing the layering of gene-drug and drug-drug interactions, G-DIG is also the first tool of its kind to incorporate the important environmental factors of tobacco smoking and coffee consumption into personalized treatment decisions.

Pharmacogenetics should not only be about the interactions of medications with body but also about interactions between drugs. With psychiatric prescribing, polypharmacy is common. G-DIG enables the Genecept Assay to be an even more complete tool, addressing both gene and drug interactions. It illustrates for the prescriber and the patient the efficacious use of medications, including their potential interactions. It can help to decrease side effects and aid in adding other medications to balance side effects, therefore decreasing noncompliance and patient hospitalization.
