Drug & supplement interaction

Bovine Colostrum + Duvelisib

Duvelisib brand name: Copiktra.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Bovine Colostrum and Duvelisib in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Bovine Colostrum and Duvelisib

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Duvelisib and Bovine Colostrum in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Bovine Colostrum at all — not against Duvelisib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Bovine Colostrum safety at a glance

Bovine Colostrum overall Use caution Generally well tolerated in most adults, but those with milk or dairy allergy should avoid it.
Pregnancy Use caution Not enough reliable safety data, so it is best to avoid unless your doctor approves.
Breastfeeding Use caution Safety is not well studied during breastfeeding, so use caution and ask your provider.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

No Interaction Found — But Data Suggests Bovine Colostrum and Duvelisib May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

Reported for Bovine Colostrum but not commonly for Duvelisib: an allergic reaction, a severe allergic reaction, hives and bloating or gas.

Effects for Duvelisib come from the ADVERSE REACTIONS section of its FDA label; effects for Bovine Colostrum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 765 voluntary FDA FAERS reports for Duvelisib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Duvelisib

By severity: 3 major · 100 moderate · 40 minor.

From our pharmacist’s overview on the Duvelisib page

“Duvelisib (Copiktra) treats certain blood cancers, and its supplement list deserves genuine care because the body clears it through a single enzyme, CYP3A4. Most of the 143 ingredients either block or speed up that enzyme, which can push duvelisib levels high enough to worsen side effects or low enough to weaken its grip on the cancer.”

About Bovine Colostrum

What is Bovine Colostrum?

Bovine Colostrum
  • Immune support
  • Gut health and digestion
  • Exercise recovery
  • Diarrhea (including infectious diarrhea)
  • Anti-inflammatory support

Bovine colostrum is the nutrient-rich first milk from cows, packed with antibodies, growth factors, and protein. Early research suggests it may help with gut health, certain types of diarrhea, and immune support, but more high-quality studies are needed. It is generally well tolerated, but people with milk allergy should avoid it, and pregnant or breastfeeding women should check with a healthcare provider first.

Colostrum (the first milk produced by cows after calving) · Powder, capsules, chewable tablets, liquid

An interaction check asks whether these two react with each other — it does not ask whether Bovine Colostrum is a good idea for someone in your situation. Here is what our Bovine Colostrum record says about it on its own.

Bovine Colostrum: dosing

There is no official standardized dose for bovine colostrum. Studies have used a wide range of amounts depending on the product and the condition being studied, so there is no single "right" dose for everyone.The best approach is to follow the directions on the product label and not take more than recommended.

About Duvelisib

What Is Duvelisib Used For?

Brand name: Copiktra

Copiktra (duvelisib) is used in adults with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) — meaning the cancer has returned or stopped responding to treatment — after at least two prior therapies.

Copiktra is also used for relapsed or refractory follicular lymphoma (FL) after at least two prior systemic therapies. The follicular lymphoma approval is based on overall response rate and is considered an accelerated approval; continued approval may depend on results from confirmatory trials. Copiktra is not intended for use as a first- or second-line treatment for any of these cancers.

Most-Reported Side Effects for Duvelisib

From FAERS, the FDA’s public side-effect reporting system (765 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 107 reports
Fatigue 78 reports
