Frequently Asked Questions
1. What is Celox?
Celox is a very effective hemostat granule optimised to stop bleeding fast. It is made of a proprietary composition which contains chitosan. Chitosan is a natural polymer extracted from shrimp shells and highly purified. Celox’s composition is protected by 3 patent applications.
2. How does Celox work to stop bleeding?
Celox™ granules are very high surface area flakes. When they come in contact with blood, Celox™ swells, gels, and sticks together to make a gel like clot, without generating any heat. It works independently of the body’s normal clotting mechanism, works in hypothermic conditions and clots blood containing the blood-thinning drug heparin*. More about how celox blood clotting agents work.
3. Where can I get the product?
Celox is sold through a network of distributors. To find out who represents Celox in your area, please contact firstname.lastname@example.org with details about your intended use.
4. Is Celox a Pharmaceutical?
No. Celox is classified and regulated by the FDA as a class II Medical Device. Medical Devices are split into categories for regulatory authority control (classes I, II, III or unclassified) covering everything from Band-aids to pacemakers. In Europe, Celox is approved as a class III device – the highest category.
5. Will Celox stop severe life threatening bleeding?
Yes, if applied to the bleeding vessel Celox can stop severe bleeding from a severed artery. This has been tested by the US military and shown in actual battlefield use. Celox is proven in the field to stop life threatening bleeding fast.
6. Will Celox granules clot blood containing anticoagulants such as Coumadin or Heparin?
Yes, Celox granules have been tested and shown to clot blood containing warfarin (Coumadin) and heparin*. The FDA have reviewed these tests and allowed us to make this claim.
7. Will Celox clot hypothermic blood?
Yes, it will stop bleeding in cold conditions. Celox has been tested and proven to clot blood as cool as 65° Fahrenheit*. The FDA have reviewed these tests as part of our registration application.
8. Can Celox be easily removed from a wound?
Yes. In cases of emergency bleeding, Celox should be left in the wound to stop bleeding until the patient in seen by medical personnel. It can then be easily removed. Remove as much of the gel like clot as possible by hand, then irrigate the wound with water or saline. In cases of minor bleeding Celox can be removed once the wound has stabilized. This can be as short as 10 minutes. Irrigate with water or saline. Chitosan is a natural polysaccharide (polymer made of sugars) and made of basic sugars (glucosamine & n-acetyl glucosamine). Celox™ does NOT use non degrading procoagulant minerals or nano particles such as kaolin, smectite or zeolite, which will remain in the body indefinitely unless physically removed.
9. What Shelf life does Celox have?
Celox has a 5 year shelf life at manufacture. We have tested and proven that Celox will still pass its original specification after 5 years ageing.
10. How much is needed to treat a severe wound?
All wounds are different but the 5-foot gauze has been tested and stopped bleeding from a major artery, as has the 15 g granules. The larger sizes (10 foot gauze, 35 g granules) give additional security for more complex injuries or multiple wounds on one casualty.
11. Is Celox suitable to stop bleeding on minor wounds?
Celox is approved for minor bleeding. There are a range of reasons why a “minor” bleed might be difficult to stop, or instances where time is crucial (for example in sports).
12. Will Celox adversely affect later wound healing?
No. Celox has been tested to show that wound healing continues normally after its use.
13. Does Celox generate heat?
No. Celox has been independently tested and shown not to generate any increase in heat during blood clotting.
14. How is Celox used?
Celox use is easy. For Celox Gauze:
- Pack any cavity with Celox Gauze.
- Press. Compress the wound to push the Celox Gauze on the area where the blood is coming from and stop blood flow for a short period while the Celox plug develops and strengthens.
For Celox Granules:
- Pour granules on to the area of the wound.
- Pack – cover the granules with gauze and fill any remaining cavity with gauze.
- Press. Compress the wound to push the Celox into place and stop blood flow for a short period while the Celox clot develops and strengthens.
The amount of time and pressure required depends on the pressure at which blood is coming out of the body. For minor wounds, finger tip pressure for one minute is recommended. For severe bleeding strong pressure is used for 3 minutes (with Celox Gauze) or up to 5 minutes (with granules). Should a wound start to re-bleed (and you believe Celox was put over the bleeding area) then just hold pressure for longer. If you suspect Celox is no longer contacting the area where the bleeding is coming from, then remove and apply a fresh pack. Additional packs can be used if required.
15. Are there any contraindications?
Celox is not intended for internal (surgical) use. Celox should not be used in the eyes. It is not indicated for use in the mouth.
16. What if I get it in my eyes?
If eye irritation occurs, flush with water for five minutes.
17. Which is the best product for me to use?
The best version depends on your application. The best place to start is to read the product section at the foot of the relevant users’ page, whether military, security and close protection services, law enforcement officer, first responder, EMT, industrial first aid or physician. These describe the most relevant products for each user. For products available to the general public please see our Celox First Aid page.
18. Do people with shellfish allergies have allergic reaction to Celox as a result of the chitosan?
There have been no known or suspected allergic reactions as a result of using Celox since its launch in 2006. The chitosan has been extensively tested on individuals with suspected and confirmed shellfish allergy, none of the test subjects demonstrated any dermal sensitivity when tested against the chitosan material.
