The bottom line No known interaction

We found no known interaction between Sida Cordifolia and Methotrexate 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

Sida Cordifolia and Methotrexate

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 Methotrexate and Sida Cordifolia 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.

How we checked

Why No Interaction Is Listed for Methotrexate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Methotrexate is filed under 6 classifications — including organic anion-transporting polypeptide substrates (oatp), organic anion transporter 3 (oat3) substrates, hepatotoxic drugs. Sida Cordifolia has documented interactions with 7 drug classes — the most serious being methylxanthines (major), qt interval-prolonging drugs (major) and stimulant drugs (major) — and none of Methotrexate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Sida Cordifolia and Methotrexate 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.

Where a percentage is shown, it is the share of 489,806 voluntary FDA FAERS reports for Methotrexate 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.

From our pharmacist’s overview on the Methotrexate page

“The liver is where methotrexate and supplements clash most. Methotrexate (Rheumatrex, Otrexup, Rasuvo), used for rheumatoid arthritis, psoriasis, and certain cancers, can strain the liver on its own, and 38 of the 82 interacting ingredients on this list add liver risk of their own, alcohol included, which makes this a list to approach…”

About Sida Cordifolia

What is Sida Cordifolia?

Sida Cordifolia
  • Weight loss and energy
  • Asthma and breathing problems
  • Joint and muscle pain
  • Fever and cough
  • General fatigue or 'tonic'

Sida cordifolia (bala or country mallow) is a traditional Ayurvedic plant that naturally contains ephedrine, a powerful stimulant. Because of this, many supplements containing it have been banned or restricted, and it carries real risks to the heart and blood pressure. There is little reliable human evidence that it works, so most people should avoid it and talk with a pharmacist or doctor first.

Sida cordifolia · Malvaceae · Whole plant, including roots, seeds, leaves, and stems · Capsules, powders, dried herb, teas, and traditional Ayurvedic preparations

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

Sida Cordifolia: dosing

There is no established safe or standardized dose for Sida cordifolia, and the amount of ephedrine in a product can vary widely and unpredictably. Many health authorities recommend avoiding ephedrine-containing supplements entirely.

About Methotrexate

What Is Methotrexate Used For?

Brand names: Rheumatrex, Otrexup, Rasuvo, Reditrex

Methotrexate treats a wide range of serious conditions. In cancer care, it is used for acute lymphoblastic leukemia, non-Hodgkin lymphoma, osteosarcoma, breast cancer, head and neck cancer, and gestational trophoblastic neoplasia (a rare tumor related to pregnancy). It is also used to prevent and treat meningeal leukemia (cancer affecting the lining of the brain and spinal cord).

Outside of cancer, methotrexate is prescribed for adults with rheumatoid arthritis (RA), children with polyarticular juvenile idiopathic arthritis (a form of childhood arthritis), and adults with severe psoriasis that hasn't responded well to other treatments.

Most-Reported Side Effects for Methotrexate

Taking Sida Cordifolia and Methotrexate Together: Common Questions

Is it safe to take Sida Cordifolia with Methotrexate?
We do not list a known interaction between Sida Cordifolia and Methotrexate. 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 Sida Cordifolia and Methotrexate have any of the same side effects?
Yes — our sources link each of them separately to 5 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.
How was the Sida Cordifolia and Methotrexate combination checked?
Interactions in our licensed database are recorded against drug classes. Methotrexate is filed under 6 classifications, and Sida Cordifolia has documented interactions with 7 drug classes — none of Methotrexate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Sida Cordifolia interact with any other medications?
Yes. Sida Cordifolia has 445 documented drug interactions in our database — Methotrexate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Methotrexate interact with any supplements?
Yes. Methotrexate has documented interactions with 82 supplements in our database — Sida Cordifolia is not one of them. The Methotrexate interaction page linked on this page lists every one, ranked by severity.
