Spinach and Dapagliflozin

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Dapagliflozin

Dapagliflozin falls under ANTIDIABETES DRUGS — the group Spinach interacts with.

There are claims that spinach leaves have hypoglycemic effects. Evidence from clinical research suggests that consumption of a spinach-rich meal reduces post-meal blood glucose levels. Theoretically, spinach might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Monitor blood glucose levels closely. Dose adjustments might be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
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 gist: some research suggests a spinach-heavy meal can nudge your blood sugar down a bit on its own. Since dapagliflozin (Farxiga) also works to lower blood sugar (by helping you pass extra sugar out in your urine), the theory is that the two together could add up and push your blood sugar a little lower than expected.

I want to be honest, though: this is a theoretical concern based on how spinach behaves, not strong proof. Normal salad-sized portions of spinach in a balanced diet are very unlikely to cause trouble. Where I'd pay more attention is with concentrated spinach extracts or supplements. If you notice shakiness, sweating, dizziness, or feeling lightheaded, check your blood sugar and loop in your pharmacist or doctor before changing anything.

About Spinach

What is Spinach?

  • General nutrition and antioxidant support
  • Eye health
  • Heart health and blood pressure
  • Athletic performance
  • Constipation and digestive support

Spinach is a nutrient-dense leafy green that is a healthy part of a balanced diet, providing vitamins, minerals, fiber, and antioxidants. While it is very safe as a food, concentrated supplements and extracts are far less studied, and most specific health claims are not strongly proven. People prone to kidney stones or taking blood thinners should be mindful of its oxalate and vitamin K content.

About Dapagliflozin

What Is Dapagliflozin Used For?

Brand name: Farxiga

Dapagliflozin is used for several serious conditions. It helps improve blood sugar control in adults and children aged 10 and older with type 2 diabetes (alongside diet and exercise). It also reduces the risk of hospitalization for heart failure in adults with type 2 diabetes who have established cardiovascular disease or multiple cardiovascular risk factors.

Farxiga (dapagliflozin) is additionally approved to reduce the risk of cardiovascular death, hospitalization, and urgent visits due to heart failure in adults with heart failure — and to slow the progression of chronic kidney disease, including reducing the risk of kidney failure and cardiovascular death, in adults with chronic kidney disease at risk of getting worse.
