Transfer Factor + Lisinopril

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Transfer Factor and Lisinopril 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.

Interaction report

Transfer Factor and Lisinopril

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 Lisinopril and Transfer Factor 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 Transfer Factor at all — not against Lisinopril, 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.

Transfer Factor safety at a glance

Transfer Factor overall Use caution Generally well tolerated in studies, but long-term safety and product quality are not well established.

Pregnancy Avoid Safety has not been established, so it is best avoided during pregnancy.

Breastfeeding Avoid Not enough safety information exists, so avoid while breastfeeding.

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 Transfer Factor and Lisinopril 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.

Fever Additional detail
Transfer Factor
“Orally or parenterally, transfer factor seems to be well tolerated. Adverse effects may include fever. Parenterally, transfer factor can cause nausea, fatigue, and tenderness, pain, and swelling at the injection site.”

Reported for Transfer Factor but not commonly for Lisinopril: acne.

Effects for Lisinopril come from the ADVERSE REACTIONS section of its FDA label; effects for Transfer Factor come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 313,746 voluntary FDA FAERS reports for Lisinopril 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.

About Transfer Factor

What is Transfer Factor?

Immune support
Preventing colds and infections
Allergies
General wellness
Chronic viral conditions

Transfer factors are small immune molecules taken from cow colostrum or egg yolk and sold as supplements meant to boost or 'train' the immune system. Solid human evidence for the supplement products is limited, and quality varies widely between brands. Talk with your pharmacist or doctor before using one, especially if you have an immune condition.

Small immune molecules (peptides) extracted from sources such as cow colostrum or hen egg yolk · Capsules, tablets, powders

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

Transfer Factor: dosing

There is no official or standardized dose for transfer factor supplements. Because products differ in how they are made and how concentrated they are, the right amount is hard to define.The safest approach is to follow the directions on the product label and not exceed the recommended amount. They can help you decide if a product is appropriate and reasonable.

About Lisinopril

What Is Lisinopril Used For?

Brand names: Zestril, Prinivil, Qbrelis

Lisinopril treats high blood pressure (hypertension) in adults and children 6 years and older, and can be used alone or alongside other blood pressure medicines. Lowering blood pressure reduces the risk of strokes and heart attacks. The tablet combination product containing lisinopril and hydrochlorothiazide is specifically indicated for high blood pressure.

Lisinopril is also used as an add-on therapy to reduce signs and symptoms of systolic heart failure, and to reduce the risk of death in people who are hemodynamically stable (have reasonably stable circulation) within 24 hours of an acute heart attack (acute myocardial infarction).

Most-Reported Side Effects for Lisinopril

From FAERS, the FDA’s public side-effect reporting system (313,746 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 20,515 reports

Nausea 19,130 reports

Diarrhea 17,858 reports

Dyspnea 14,363 reports

Dizziness 13,969 reports

Taking Transfer Factor and Lisinopril Together: Common Questions

Is it safe to take Transfer Factor with Lisinopril?

We do not list a known interaction between Transfer Factor and Lisinopril. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.

Do Transfer Factor and Lisinopril have any of the same side effects?

Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.

Does Lisinopril interact with any supplements?

Yes. Lisinopril has documented interactions with 167 supplements in our database — Transfer Factor is not one of them. The Lisinopril interaction page linked on this page lists every one, ranked by severity.
