Diosmin and Amphotericin, Tetracycline

Here is the interaction we found between these two, with the evidence behind it.

Moderate

P-GLYCOPROTEIN SUBSTRATES

Why this applies to Amphotericin, Tetracycline

Amphotericin, Tetracycline falls under P-GLYCOPROTEIN SUBSTRATES — the group Diosmin interacts with.

Theoretically, diosmin might increase levels of drugs that are substrates of P-glycoprotein (P-gp).
Preliminary laboratory research suggests that diosmin inhibits P-gp. Additionally, pharmacokinetic research in healthy male subjects shows that taking diosmin (Venex) 500 mg daily for 10 days prior to oral administration of fexofenadine 120 mg increases blood levels of fexofenadine, a P-gp substrate, by approximately 49% and decreases the apparent oral clearance of fexofenadine by 41%. The time taken to reach maximum plasma concentration, the half-life, and the apparent renal clearance of fexofenadine are not affected. For this reason, it is speculated that diosmin inhibits P-gp in the intestine, but not in the kidney or liver.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the basic idea: diosmin may gently block a transporter called P-glycoprotein (P-gp) in your gut, which helps move some drugs back out of your body. If that transporter is slowed, a little more of certain medications can get absorbed. With this combination product (a tetracycline antibiotic paired with amphotericin), diosmin could theoretically nudge blood levels of the tetracycline portion upward, which might mean a bit more stomach upset, nausea, or sun sensitivity.

Honestly though, this is theoretical and based only on lab and animal data, so it's not something to lose sleep over. Tetracyclines are already best taken away from calcium, dairy, and antacids, so timing matters more than diosmin here. Just mention you take diosmin to your pharmacist so they can keep an eye on things.
