Super warfarin is a poison that can be found in many products to kill rats and roaches. However, it is also used very cautiously to treat patients that have heart disease. Small amounts of it are used as a blood thinner but if used too much it can cause bleeding to death.

You can be exposed if you eat foods contaminated with super warfarin. If you work in an industry that makes products such as rat and roach killer, you can be exposed.

It depends on the amount, the route and the length of time of the exposure to super warfarin. Usually, an exposed person will get sick within 24 to 72 hours.

If you are exposed to a large amount of super warfarin, you will experience the following symptoms: abnormal bleeding, vomiting blood, bleeding in the mouth (gums), blood in the feces, blood in the urine and non-stop nose bleeding.

If you think you have been exposed, leave the area quickly and get to fresh air. Remove your clothing and quickly wash your entire body with soap and water. If your eyes are burning or your vision is blurred, rinse them with plain water for 10 to 15 minutes. If you wear contacts, remove them before rinsing your eyes. Place your contaminated clothes and contact lenses into a plastic bag and seal. Place the bag into a second plastic bag and seal. If you have swallowed the phosgene oxime, do not induce vomiting or drink fluids. Call 911 for medical attention and removal of the contaminated items. Do not drive yourself to the hospital as you may become very ill on your way.
