Ketogenic Diet and Iloprost

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

Minor

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Iloprost

Iloprost falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Ketogenic Diet interacts with.

Although there is some concern that the ketogenic diet might have additive effects when used with anticoagulant and antiplatelet drugs, most clinical research does not show this effect.
One small observational study found that the ketogenic diet was associated with prolonged bleeding times in 16 of 51 (31%) children with epilepsy who were also on chronic anticonvulsant therapy. However, a larger observational study of 162 children with epilepsy taking chronic anticonvulsants has found that following the ketogenic diet does not increase the risk of bleeding, even in the 25 children undergoing surgery. Research in adults also has not reported changes in bleeding time.
Severity Minor Likelihood Unlikely Evidence B

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the gist for Iloprost (Ventavis): besides relaxing the blood vessels in your lungs, it also makes your platelets a little less sticky, so it has a mild blood-thinning quality. The theoretical worry is that a ketogenic diet might add to that and stretch out bleeding times a bit.

The good news is that the evidence here is reassuring. The one small study that noticed longer bleeding times wasn't backed up by larger research in kids or adults, so for most people this is unlikely to cause a real problem. Still, if you notice easy bruising, nosebleeds, or bleeding that's slow to stop, or you have surgery coming up, mention the diet to your doctor or pharmacist so they can keep an eye on things.

About Ketogenic Diet

What is Ketogenic Diet?

  • Weight loss
  • Type 2 diabetes and blood sugar control
  • Drug-resistant epilepsy (especially in children)
  • Reducing appetite
  • Athletic and metabolic interest

The ketogenic diet is a very low-carbohydrate, high-fat eating plan that shifts the body to burn fat for fuel. It has the strongest evidence as a medical therapy for hard-to-treat epilepsy and may help short-term weight loss and blood sugar, but it can be hard to sustain and is not right for everyone. Talk with a doctor or pharmacist before starting, especially if you have a medical condition or take medication.
