Bitter Orange and Albiglutide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Albiglutide

Albiglutide falls under ANTIDIABETES DRUGS — the group Bitter Orange interacts with.

Theoretically, bitter orange might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Some clinical research shows that drinking a tea containing bitter orange and Indian snakeroot reduces fasting and postprandial glucose levels in patients with type 2 diabetes who are using antidiabetes drugs. However, it is unclear if these effects are due to bitter orange, Indian snakeroot, or the combination. An animal study also shows that p-synephrine in combination with gliclazide , a sulfonylurea, causes an additional 20% to 44% decrease in glucose levels when compared with gliclazide alone.
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 explains PharmD, Clinical Pharmacist

Here's the gist if you're using Tanzeum (albiglutide) and thinking about a bitter orange supplement. Albiglutide is an injectable that helps your pancreas release insulin and lowers blood sugar, especially after meals. There's some early, lower-quality research suggesting bitter orange may nudge blood sugar down a little on its own. Stacked on top of albiglutide, the theory is that the two together could push your numbers too low.

This is mostly theoretical and the evidence is shaky, so I wouldn't panic. But it's worth knowing the signs of low blood sugar: shakiness, sweating, dizziness, a racing heartbeat, or confusion. Bitter orange can also bump up heart rate and blood pressure by itself. Please check with your pharmacist or doctor before adding it, and keep monitoring your glucose.

From our pharmacist’s overview on the Albiglutide page

“People injecting albiglutide (Tanzeum) once a week for type 2 diabetes are often the same people eyeing supplements marketed for blood sugar, and that overlap is exactly where this list calls for real vigilance. Every one of the 239 ingredients on file touches glucose control in some way, most by adding to albiglutide's glucose-lowerin…”

About Bitter Orange

What is Bitter Orange?

Bitter Orange
  • Weight loss
  • Athletic performance and energy
  • Digestive upset
  • Appetite control
  • Aromatherapy for stress (neroli oil)

Bitter orange is a citrus fruit whose extracts contain synephrine, a mild stimulant often added to weight-loss and energy supplements. Evidence that it works for weight loss or performance is limited, and because it can raise heart rate and blood pressure, people with heart problems, high blood pressure, or who are pregnant should avoid it. Talk to your pharmacist or doctor before using it, especially if you take other stimulants.
