Ketogenic Diet and Ticlopidine

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

Minor

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Ticlopidine

Ticlopidine 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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the situation with the ketogenic diet and ticlopidine. Ticlopidine is a blood thinner that keeps your platelets from sticking together, which is exactly what it's supposed to do. The theory floating around is that going keto might add a little extra to that effect and stretch out your bleeding time slightly.

The good news? Most of the research doesn't back this up. One small study in kids hinted at longer bleeding times, but a larger study found no real increase in bleeding risk, even in children having surgery, and adult studies showed no change either. So this is rated minor and unlikely. Still, if you notice easy bruising, nosebleeds, or bleeding that won't stop, loop in your pharmacist or doctor.

From our pharmacist’s overview on the Ticlopidine page

“Ticlopidine (Ticlid) keeps platelets from clumping to prevent clots, so it already raises bleeding risk on its own, and over 200 of the 221 supplements flagged for it push in that same direction. That stacking effect deserves genuine respect from anyone taking this drug.”

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.

About Ticlopidine

What Is Ticlopidine Used For?

Brand names: Ticlid, Ticlopidine

  • Ticlopidine is used to reduce the risk of stroke in people who have had a stroke or have had warning signs of a stroke and who cannot be treated with aspirin. Ticlopidine is also used along with aspirin to prevent blood clots from forming in coronary stents (metal tubes surgically placed in clogged blood vessels to improve blood flow). It works by preventing platelets (a type of blood cell) from collecting and forming clots.
