Fig and pioglitazone, metformin

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

Moderate

ANTIDIABETES DRUGS

Why this applies to pioglitazone, metformin

pioglitazone, metformin falls under ANTIDIABETES DRUGS — the group Fig interacts with.

Theoretically, fig leaf might enhance the blood glucose lowering effects of hypoglycemic drugs.
A small clinical study in patients with type 1 diabetes shows that consuming a tea made from fig leaves modestly reduces postprandial glucose levels and insulin requirements.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the simple version. Your ActoPlus Met combines two diabetes medicines, pioglitazone and metformin, and both work to bring your blood sugar down. Fig leaf, especially as a concentrated tea or supplement, may also nudge blood sugar lower on its own. Stack the two together and you could end up lower than intended. That can show up as shakiness, sweating, dizziness, headache, or feeling suddenly hungry or weak.

This isn't a scary or dangerous combination, and it's based on a small study, so I'd call it modest. Just eating a fig or two as fruit is unlikely to cause trouble. If you want to use fig leaf tea or capsules regularly, check with your pharmacist or doctor first, and keep an eye on your home glucose readings so nothing sneaks up on you.

About Fig

What is Fig?

  • Constipation and digestive health
  • Blood sugar support
  • Cough and sore throat
  • Skin conditions (topical sap)
  • Source of fiber and minerals

Fig (Ficus carica) is a common fruit that has long been used as a gentle food remedy for constipation, and its leaves are used traditionally for blood sugar and coughs. The fruit is a safe and nutritious food, but evidence for fig leaf supplements treating specific health conditions is limited. Talk to your pharmacist or doctor before using concentrated fig leaf products, especially if you have diabetes.
