Drug & supplement interaction

Glutathione + Lenalidomide

Lenalidomide brand name: Revlimid.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Glutathione and Lenalidomide 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.

Glutathione and Lenalidomide

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 Lenalidomide and Glutathione 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 Glutathione at all — not against Lenalidomide, 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.

Glutathione safety at a glance

Glutathione overall Use caution Oral forms appear generally well tolerated short-term, but long-term safety and the safety of IV and inhaled forms are less clear.
Pregnancy Avoid There is not enough reliable safety information, so it is best avoided during pregnancy unless your doctor advises otherwise.
Breastfeeding Avoid There is not enough reliable safety information during breastfeeding, so caution and avoidance are advised.

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 Glutathione and Lenalidomide 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. One of them is worth acting on rather than waiting out — marked below.

Reported for Glutathione but not commonly for Lenalidomide: wheezing.

Effects for Lenalidomide come from the ADVERSE REACTIONS section of its FDA label; effects for Glutathione come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 420,080 voluntary FDA FAERS reports for Lenalidomide 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 Glutathione

What is Glutathione?

Glutathione
  • Antioxidant support
  • Skin lightening or brightening
  • Detoxification support
  • Immune support
  • Liver health
  • Anti-aging

Glutathione is a powerful antioxidant your body makes naturally, and many people take it as a supplement hoping for skin, detox, or anti-aging benefits. However, strong human evidence is limited for most uses, and oral glutathione is poorly absorbed. Talk to your pharmacist or doctor before starting, especially if you are considering IV or inhaled forms.

Not applicable (a compound made of three amino acids: cysteine, glutamic acid, and glycine) · Oral capsules and tablets, liposomal liquid, lozenges, intravenous (IV) injections, nebulized (inhaled) forms, topical creams

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

Glutathione: dosing

There is no official, standardized dose of glutathione for any health condition. Supplement products vary widely in their form and amount.The best advice is to follow the directions on the product label and not exceed them. Because oral glutathione is poorly absorbed, taking more does not necessarily mean more benefit.IV and inhaled forms should only be used under the care of a healthcare provider.

About Lenalidomide

What Is Lenalidomide Used For?

Brand name: Revlimid

Lenalidomide capsules (brand names Revlimid and Lenalidomide) are used to treat several blood cancers and related conditions in adults. These include multiple myeloma (MM) — both in combination with dexamethasone and as maintenance therapy after a stem cell transplant — and transfusion-dependent anemia caused by low- or intermediate-1-risk myelodysplastic syndromes (MDS) linked to a specific chromosome change called deletion 5q.

Lenalidomide capsules are also used for mantle cell lymphoma (MCL) that has come back or stopped responding after at least two prior treatments (one of which included bortezomib). In combination with a rituximab product, they treat previously treated follicular lymphoma (FL) and previously treated marginal zone lymphoma (MZL). Lenalidomide is not approved for chronic lymphocytic leukemia (CLL) outside of clinical trials.

Most-Reported Side Effects for Lenalidomide

From FAERS, the FDA’s public side-effect reporting system (420,080 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 31,469 reports
Fatigue 26,781 reports
Pneumonia 18,843 reports
Rash 18,228 reports

Taking Glutathione and Lenalidomide Together: Common Questions

Is it safe to take Glutathione with Lenalidomide?
We do not list a known interaction between Glutathione and Lenalidomide. 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 Glutathione and Lenalidomide have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Lenalidomide interact with any supplements?
Yes. Lenalidomide has documented interactions with 70 supplements in our database — Glutathione is not one of them. The Lenalidomide interaction page linked on this page lists every one, ranked by severity.
