Can I take IMBXX with other supplements or medications?

Certain medications and compounds may impact the efficacy of IMBXX® and the health of your microbiome, which plays a key role in immune function and overall wellness. For example:

  • Antibiotics and anti-inflammatory drugs like ibuprofen and naproxen may negatively affect the microbiome.
  • Pain medications containing opiates or narcotics can influence the gut-brain axis and brain receptors.
  • Psychiatric and central nervous system medications—including Duloxetine, Pregabalin, Gabapentin, Aripiprazole, Fluoxetine, Sertraline, Paroxetine, Citalopram, Escitalopram, Trazodone, Naltrexone, and Milnacipran—may interfere with how IMBXX® works.

Because interactions can vary widely, we strongly recommend discussing all medications and supplements with your doctor or healthcare provider before or while taking IMBXX®. 

Disclaimer: We will never recommend, direct, or advise you to stop or change any prescription medications. All decisions regarding prescription use should be made in consultation with your licensed medical professionals.
