Feverfew and Alogliptin, Pioglitazone

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

Why Are There 2 Interactions?

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Alogliptin, Pioglitazone

Alogliptin, Pioglitazone falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Feverfew interacts with.

Theoretically, feverfew might increase levels of drugs metabolized by CYP3A4.
Laboratory research shows that feverfew might inhibit CYP3A4. So far, this interaction 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

Oseni combines two diabetes medicines, and the pioglitazone part is partly cleared by a liver enzyme called CYP3A4. In the test tube, feverfew seems to slow that enzyme down a bit. In theory, that could let pioglitazone build up slightly, which might nudge its effects (and side effects) a little stronger. With pioglitazone, that could mean things like fluid retention, swelling in the legs, or low blood sugar when paired with other glucose-lowering drugs.

Here's the honest part though: this is only seen in lab studies, not in real people. So I wouldn't lose sleep over it. Just let your pharmacist or doctor know if you'd like to add feverfew, and keep an eye on how you feel and your blood sugar readings.

CYTOCHROME P450 2C8 (CYP2C8) SUBSTRATES

2 of 2

Alogliptin, Pioglitazone also falls under CYTOCHROME P450 2C8 (CYP2C8) SUBSTRATES.

Theoretically, feverfew might increase levels of drugs metabolized by CYP2C8.
Laboratory research shows that feverfew might inhibit CYP2C8. So far, this interaction 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 explains PharmD, Clinical Pharmacist

Oseni combines two diabetes medicines, and the pioglitazone part is cleared by a liver enzyme called CYP2C8. Lab studies hint that feverfew may slow this enzyme down. If that happened in people, pioglitazone could build up a bit, which in theory might push your blood sugar lower than expected or add to side effects like fluid retention, swelling in the legs, or weight gain.

The important thing to know is that this is only test-tube research. It has never actually been reported in real patients, so the concern is theoretical and likely small. Still, since you are managing diabetes, it is worth mentioning feverfew to your pharmacist or doctor before you start it, and keep an eye on how you feel and your sugar 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 Feverfew

What is Feverfew?

Feverfew
  • Migraine prevention
  • Headache
  • Fever (traditional)
  • Arthritis and joint pain
  • Menstrual discomfort

Feverfew is a daisy-family herb best known for migraine prevention, where some studies suggest it may modestly lower how often migraines occur, though the evidence is mixed. It is generally well tolerated for short-term use in most adults but should be avoided during pregnancy and breastfeeding and by people allergic to ragweed and related plants. Talk to your pharmacist or doctor before starting it.
