Interaction report

Turmeric and Alogliptin

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Turmeric interacts with whole categories of medication. Alogliptin falls into 3 of those categories, so it can interact with Turmeric in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

HEPATOTOXIC DRUGS

1 of 3

Why this applies to Alogliptin

Alogliptin falls under HEPATOTOXIC DRUGS — the group Turmeric interacts with.

Theoretically, turmeric might increase the risk of liver damage when taken with hepatotoxic drugs.
There is concern that turmeric might cause hepatotoxicity, especially when highly bioavailable formulations are used in high doses.
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 explains PharmD, Clinical Pharmacist

Here's the gist with turmeric and alogliptin (Nesina): this isn't about turmeric changing how your diabetes medicine works or how it's broken down. Alogliptin doesn't need turmeric to activate it, and turmeric won't make your blood sugar swing up or down on its own. The concern is a different one. Both can, in rare cases, be tough on the liver, so the worry is about stacking two things that each carry a small liver risk.

To be honest, this is mostly theoretical and based on scattered case reports, usually tied to high-dose, highly absorbable curcumin products, not the turmeric you sprinkle on food. Cooking amounts are very unlikely to matter. If you take a concentrated supplement, mention it to your pharmacist or doctor so your liver labs can be watched, and flag any yellowing skin, dark urine, or belly pain.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 3

Alogliptin also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Turmeric might increase or decrease levels of drugs metabolized by CYP3A4.
In vitro and animal research show that turmeric and its constituents curcumin and curcuminoids inhibit CYP3A4. Also, 8 case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking turmeric and cancer medications that are CYP3A4 substrates, including everolimus, ruxolitinib, ibrutinib, and palbociclib, and bortezomib. In another case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels after consuming turmeric powder at a dose of 15 or more spoonfuls daily for ten days prior. It was thought that turmeric increased levels of tacrolimus due to CYP3A4 inhibition.
Conversely, other in vitro research suggests that turmeric induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. An animal model suggests that induction of CYP3A4 occurs after daily curcumin use for 1 week. However, the induction of CYP3A4 by turmeric has not been reported in humans.
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 good news with alogliptin (Nesina): even though turmeric can tug on the CYP3A4 enzyme system, this particular diabetes drug doesn't lean heavily on CYP3A4 to be cleared. Most alogliptin actually leaves your body unchanged through the kidneys, so any push or pull turmeric has on that enzyme isn't likely to move your blood sugar control much one way or the other.

On top of that, the worry here is mostly theoretical, based on lab and animal studies rather than real patients on alogliptin. Cooking with turmeric in your food is no concern at all. If you're taking concentrated curcumin capsules, it's still smart to check in with your pharmacist or doctor and keep an eye on your sugar readings, but I wouldn't lose sleep over this combination.

ANTIDIABETES DRUGS

3 of 3

Alogliptin also falls under ANTIDIABETES DRUGS.

Theoretically, taking turmeric with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research and case reports suggest that curcumin, a turmeric constituent, can reduce blood glucose levels in patients with diabetes. Furthermore, clinical research in adults with type 2 diabetes shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg decreased postprandial glucose levels for up to 24 hours when compared with glyburide alone, despite the lack of a significant pharmacokinetic interaction. Other clinical studies in patients with diabetes show that taking curcumin daily can reduce blood glucose levels when compared with placebo.
Severity Moderate 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

Here's the gist: turmeric, specifically its active compound curcumin, may gently lower blood sugar on its own. Since alogliptin (Nesina) is already working to bring your glucose down, stacking the two could push your blood sugar a little lower than expected. This isn't about turmeric changing how your body breaks the drug down. It's simply two things nudging blood sugar in the same direction.

Be honest, the evidence here is on the softer side, coming from animal studies, case reports, and a small human trial using another diabetes pill. Alogliptin by itself rarely causes low blood sugar, so the real risk is modest. Still, if you take concentrated curcumin supplements, it's worth watching for shakiness, sweating, or dizziness, and checking your readings. Loop in your pharmacist or doctor before adding it.

About Turmeric

What is Turmeric?

Turmeric
  • Joint pain and arthritis
  • Inflammation
  • Digestive upset
  • Antioxidant support
  • Skin conditions

Turmeric is a popular spice whose main active compounds, curcuminoids, are studied mostly for inflammation and joint pain. Some research is promising, but quality is mixed and curcumin is poorly absorbed on its own. For most people, dietary amounts are safe, but talk to your pharmacist or doctor before taking concentrated supplements, especially if you are pregnant, nursing, or have a medical condition.
