Cucumber and Linagliptin, Metformin Hydrochloride

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Linagliptin, Metformin Hydrochloride

Linagliptin, Metformin Hydrochloride falls under ANTIDIABETES DRUGS — the group Cucumber interacts with.

Theoretically, cucumber seed might have additive effects with antidiabetes drugs and may increase the risk of hypoglycemia.
Animal research shows that cucumber seed extract can decrease blood glucose levels. Monitor blood glucose levels closely.
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 simple version: Jentadueto XR (linagliptin plus metformin) already works to lower your blood sugar. The thought is that concentrated cucumber seed extract might nudge your blood sugar down a little further, so the two together could, in theory, push you toward a low (hypoglycemia). With this combo, that might show up as shakiness, sweating, dizziness, hunger, or feeling foggy.

Honestly though, this is a very weak concern. The evidence comes only from animal studies using concentrated seed extract, not from people. Eating cucumber as a normal food is extremely unlikely to cause any trouble. If you're using a strong cucumber seed supplement, just keep an eye on your readings and mention it to your pharmacist or doctor.

From our pharmacist’s overview on the Linagliptin, Metformin Hydrochloride page

“Someone taking Jentadueto XR (linagliptin and metformin) for type 2 diabetes is often the same person eyeing fenugreek, bitter melon, or gymnema, and that overlap is why this page deserves real caution. Of its 285 ingredients, 239 can lower blood sugar on their own, so stacking them on a drug already doing that job risks pushing glucos…”
