The bottom line No known interaction

We found no known interaction between Dragon's Blood and Zafirlukast 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.

Dragon's Blood and Zafirlukast

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 Zafirlukast and Dragon's Blood 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 Dragon's Blood at all — not against Zafirlukast, 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.

Dragon's Blood safety at a glance

Dragon's Blood overall Use caution Topical use is generally considered low-risk for most people, but human safety data are limited and product sources vary.
Pregnancy Avoid There is not enough safety information, so it is best to avoid use during pregnancy.

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

What Zafirlukast’s Own FDA Label Lists

This is not an interaction — none of it involves Dragon's Blood. These are the most notable effects listed in the ADVERSE REACTIONS section of Zafirlukast’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. 9 of them are worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on mentioned in 16.1% of FDA reports for Zafirlukast
  • Low mood Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Back pain

Showing the 10 most notable of 25 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 Zafirlukast. Read the label on DailyMed › Where a percentage is shown, it is the share of 864 voluntary FDA FAERS reports for Zafirlukast that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Dragon's Blood’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Dragon's Blood side to compare — that is a limit of the record, not a statement that Dragon's Blood has no side effects.

About Dragon's Blood

What is Dragon's Blood?

Dragon's Blood
  • Wound healing and skin care
  • Digestive upset and diarrhea
  • Minor cuts and insect bites
  • Sore throat and mouth sores
  • Anti-inflammatory skincare

Dragon's Blood is a red plant resin used in traditional medicine for wound healing, skin problems, and digestive complaints. Some early research on certain types (especially Croton lechleri "Sangre de Drago") is promising for the gut and skin, but high-quality human evidence is limited. Talk with your pharmacist or doctor before using it, especially while pregnant or breastfeeding.

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

Dragon's Blood: dosing

There is no established standard dose for Dragon's Blood. The right amount depends on the specific plant source, the product type (resin, tincture, capsule, or cream), and how it is being used.If you choose to use a Dragon's Blood product, follow the directions on the label and do not exceed the suggested amount.
