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

Moderate

ANTIDIABETES DRUGS

Why this applies to Alogliptin, Pioglitazone

Alogliptin, Pioglitazone falls under ANTIDIABETES DRUGS — the group Winter Cherry interacts with.

In animal diabetic models, winter cherry extract decreases blood glucose. This effect has not been shown in humans. Theoretically, winter cherry might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
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 explains PharmD, Clinical Pharmacist

Oseni combines two diabetes medicines, alogliptin and pioglitazone, that both work to lower your blood sugar. Here's the thing with Winter Cherry (ashwagandha): in animal studies it appeared to nudge blood sugar down too. That hasn't been proven in people, so this is more of a theoretical concern than something we've clearly seen happen. Still, the worry is simple addition. If the herb lowers sugar a little and your Oseni is already doing its job, the two together could push you too low.

What would low blood sugar feel like? Shakiness, sweating, dizziness, a fast heartbeat, or feeling foggy. If you'd like to try Winter Cherry, just give your pharmacist or doctor a heads-up first and keep an eye on your glucose readings.

From our pharmacist’s overview on the Alogliptin, Pioglitazone page

“Someone taking Oseni (alogliptin and pioglitazone) for type 2 diabetes often shops the very shelf this list comes from, and the pairing deserves genuine caution. Of the 356 ingredients on file, 239 also lower blood sugar, so stacking them on top of the pill can drop glucose too far.”

About Winter Cherry

What is Winter Cherry?

  • Stress and anxiety
  • Fatigue and low energy
  • Sleep support
  • General vitality and tonic
  • Athletic performance

Winter Cherry is another name for ashwagandha (Withania somnifera), an herb long used in Ayurvedic medicine, most often for stress, sleep, and energy. Some small studies suggest it may help with stress and anxiety, but the evidence is still limited and not definitive. It is generally well tolerated short-term, but pregnant women should avoid it, and anyone with a health condition should check with a pharmacist or doctor first.
