The bottom line No known interaction

We found no known interaction between Lemongrass and Ranibizumab 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.

Interaction report

Lemongrass and Ranibizumab

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 Ranibizumab and Lemongrass 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.

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.

What to actually watch for

What Ranibizumab’s Own FDA Label Lists

This is not an interaction — none of it involves Lemongrass. These are the most notable effects listed in the ADVERSE REACTIONS section of Ranibizumab’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 5 of them are worth acting on rather than waiting out — marked below.

  • An irregular heartbeat Worth acting on
  • Kidney problems Worth acting on
  • Bleeding or bruising Worth acting on mentioned in 4.0% of FDA reports for Ranibizumab
  • Anemia Worth acting on
  • A higher chance of infection Worth acting on
  • Blurred vision mentioned in 21.1% of FDA reports for Ranibizumab
  • Eye irritation or redness
  • Dry eyes
  • Heartburn
  • Numbness or tingling

Showing the 10 most notable of 16 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Ranibizumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 26,416 voluntary FDA FAERS reports for Ranibizumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Lemongrass’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Lemongrass side to compare — that is a limit of the record, not a statement that Lemongrass has no side effects.

Overlapping uses

What Ranibizumab Is Prescribed For, and What Lemongrass Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Ranibizumab is a prescription medicine with approved uses on its FDA label. Lemongrass is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Ranibizumab is prescribed for: Ranibizumab injection treats serious eye conditions that involve abnormal blood vessel growth or fluid leakage in the eye. It is used for neovascular (wet) age-related macular degeneration (AMD), diabetic macular edema (DME), and diabetic retinopathy (DR). Susvimo (ranibizumab injection) is specifically approved for patients with wet AMD, DME, or DR who have already responded to at least two intravitreal (into-the-eye) injections of a VEGF inhibitor medication. Lucentis (ranibizumab injection) is used for wet AMD, DME, diabetic retinopathy, macular edema following retinal vein occlusion, and myopic choroidal neovascularization (abnormal blood vessel growth related to severe nearsightedness).

Lemongrass has been studied for:

  • Diabetes studied, not established Lemongrass has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Lemongrass for diabetes

    Although there has been interest in using oral lemongrass for diabetes, there is insufficient reliable information about the clinical effects of lemongrass for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Ranibizumab on your own; if you are taking Lemongrass for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Lemongrass

What is Lemongrass?

Lemongrass
  • Digestive upset
  • Anxiety and stress
  • Antimicrobial/antifungal
  • Insect repellent
  • Flavoring in food and drinks

Lemongrass is a fragrant tropical grass widely used as a cooking herb, a tea, and an aromatherapy oil. It is generally considered safe in the small amounts used in food, but most of its claimed health benefits come from laboratory or animal studies rather than strong human research. Talk with your pharmacist or doctor before using concentrated supplements or the essential oil, especially if you are pregnant or breastfeeding.

Cymbopogon citratus · Poaceae · Leaves, stalks, and essential oil · Tea, fresh or dried herb, capsules, essential oil, topical preparations

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

Lemongrass: dosing

There is no official standardized dose for lemongrass. The amount used depends on the form, such as tea, capsule, or essential oil.For tea, people commonly steep a small amount of dried or fresh leaves in hot water. For supplements, follow the directions on the product label, since strength varies from brand to brand.

Taking Lemongrass and Ranibizumab Together: Common Questions

Is it safe to take Lemongrass with Ranibizumab?
We do not list a known interaction between Lemongrass and Ranibizumab. 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.
Are Lemongrass and Ranibizumab used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Lemongrass in each. That is a conversation for your prescriber, especially if Ranibizumab is being adjusted to a target.
Does Lemongrass interact with any other medications?
Yes. Lemongrass has 708 documented drug interactions in our database — Ranibizumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
