SEAL Hemostatic Spray OTC - for Emergency Bleeding Control

Key Specifications

Product Overview

SEAL Hemostatic Spray OTC brings the world's first FDA-cleared chitosan aerosol hemostatic technology to civilian and consumer markets. The OTC version is indicated for the local management of minor bleeding — minor lacerations, cuts, and abrasions — making it appropriate for household first aid kits, outdoor recreation, sporting events, school nurse offices, vehicles, and public-access bleeding control stations. Unlike the Rx-labeled PRO version, the OTC version does not require a prescription and is accessible to any consumer without medical training.

The underlying technology is identical to the PRO version: medical-grade chitosan dry powder delivered as a pressurized aerosol that, upon contact with blood, forms a rapid physical barrier to stop bleeding. The chitosan mechanism (direct red blood cell adhesion) is independent of the clotting cascade, meaning it works in patients on blood thinners and in cold conditions. The barrier begins forming within approximately 30 seconds of application. The cold propellant provides mild vasoconstriction on contact, providing an additional physiological mechanism to reduce blood flow at the wound site. SEAL does not generate heat, does not cause systemic clotting, and is removed easily with saline or sterile water.

The 1.5 oz OTC can is the most compact and portable SEAL format — easily stored in a small first aid kit, glove compartment, day pack, or purse. The "shake, point, spray" deployment requires zero training, making it accessible to bystanders and non-medical personnel responding to a bleeding emergency before EMS arrival. At 2.5 years shelf life without refrigeration, it provides a reasonable service life for consumer kits with periodic rotation. The OTC version represents an important step in democratizing access to effective hemostatic technology — moving beyond the traditional gauze-and-pressure approach to a single-handed, no-excavation first response tool.

How to Use

1. Shake the can well before use.
2. Hold can 6–10 inches from the wound.
3. Spray directly onto the bleeding area for approximately 5 seconds.
4. Apply gentle direct pressure over the sprayed surface while the chitosan barrier forms (approximately 30 seconds).
5. Apply a bandage or dressing to maintain pressure and protect the barrier.
6. Remove with water or saline rinse when bleeding has stopped and wound care is complete.
7. For serious injuries, call 911 — SEAL OTC is first aid for minor wounds; it does not replace professional emergency care.

OTC vs. PRO: Which to Choose

The OTC and PRO versions contain the same chitosan aerosol formulation. The difference is the regulatory label and intended use context: OTC is cleared for minor bleeding control and is available to consumers without a prescription; PRO carries an Rx label cleared for "temporary control of severe topical bleeding" in emergency situations, intended for trained medical providers, EMS, law enforcement, and military medics. For professional responders building IFAKs, duty bags, or unit medical kits, the SEAL PRO is appropriate. For civilian preparedness, home first aid, and public-access kits, the OTC version provides an accessible, no-prescription hemostatic spray.
