Apple Cider Vinegar and Insulin Glargine, Lixisenatide

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Apple Cider Vinegar interacts with whole categories of medication. Insulin Glargine, Lixisenatide falls into 2 of those categories, so it can interact with Apple Cider Vinegar in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

INSULIN

1 of 2
Theoretically, concomitant use of apple cider vinegar with insulin might increase the risk of hypokalemia.
A case of hypokalemia related to chronic use of apple cider vinegar has been reported. Theoretically, overuse of apple cider vinegar concomitantly with insulin might increase the risk of hypokalemia.
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

Soliqua is a once-daily injection that pairs a long-acting insulin (glargine) with lixisenatide to lower blood sugar. Insulin already nudges potassium out of your bloodstream and into your cells, which can lower your blood potassium a little. The concern here is that apple cider vinegar, when used heavily over a long time, has been tied to low potassium (hypokalemia) in a rare case report, so stacking the two might add up.

I want to be honest about how thin this evidence is: it's mostly theory plus one anecdote, not solid proof. A splash of vinegar on your salad isn't the worry. Drinking large amounts of straight ACV daily is. If you notice muscle cramps, weakness, or an odd heartbeat, or you're a heavy ACV user, please check in with your pharmacist or doctor before changing anything.

ANTIDIABETES DRUGS

2 of 2

Why this applies to Insulin Glargine, Lixisenatide

Insulin Glargine, Lixisenatide falls under ANTIDIABETES DRUGS — the group Apple Cider Vinegar interacts with.

Theoretically, taking apple cider vinegar with antidiabetes drugs might increase the risk of hypoglycemia.
Apple cider vinegar might reduce fasting and postprandial blood glucose levels and decrease gastric emptying in people with diabetes. However, not all research agrees. Theoretically, it might have additive effects on glucose levels when used with antidiabetes drugs.
Severity Minor Likelihood Possible Evidence B

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

Soliqua already combines two strong blood-sugar lowerers: insulin glargine (a long-acting insulin) and lixisenatide. Apple cider vinegar may nudge your blood sugar down a little on its own, partly by slowing how fast your stomach empties. Stacked on top of Soliqua, the worry is simply that your numbers could drift a bit lower than expected. That could show up as shakiness, sweating, a fast heartbeat, dizziness, or trouble concentrating.

This is rated a minor, mostly theoretical concern, and the studies are small and mixed, so it is not a reason to panic. A splash of vinegar on a salad is unlikely to matter much. If you take concentrated ACV daily, keep checking your sugars and tell your pharmacist or doctor before changing anything.

“Soliqua 100/33 pairs a long-acting insulin, glargine, with lixisenatide, so its whole job is pushing blood sugar down, and that is also what most of the 242 supplements and herbs on this list do. The overlap earns real caution here.”

About Apple Cider Vinegar

What is Apple Cider Vinegar?

Apple Cider Vinegar
  • Blood sugar support
  • Weight management
  • Digestive upset
  • Appetite control
  • Skin and hair care

Apple cider vinegar is a fermented apple product that many people use hoping to help with blood sugar, weight, or digestion. The evidence for most of these uses is limited and mixed, and the modest effects seen in small studies are not a substitute for proven treatments. When diluted and used in small amounts it is generally safe for most people, but undiluted vinegar can harm teeth and the throat.
