* The time the poisoning occurred (if known).
* The person’s condition and symptoms.
* Your location.
* **Follow Instructions:** Follow the instructions provided by the emergency dispatcher or the Poison Control Center. They will guide you on the appropriate steps to take.

### 3. Initial Treatment Steps Based on the Route of Exposure:

#### Ingestion (Swallowing)

* **Do NOT Induce Vomiting Unless Instructed:** This is a critical point. Inducing vomiting can cause more harm than good, especially if the substance is corrosive or a petroleum product. Vomiting can cause further damage to the esophagus and airways. Always follow the instructions of the Poison Control Center or emergency medical personnel.
* **If the Person is Alert and Conscious:**
* Rinse the mouth with water.
* Give small sips of water or milk (if instructed by Poison Control).
* **If the Person is Unconscious, Having Difficulty Breathing, or Seizing:**
* Do not give anything by mouth.
* Turn the person onto their side to prevent choking.
* Monitor their breathing and pulse.
* Be prepared to perform CPR if necessary.

#### Inhalation (Breathing In)

* **Move the Person to Fresh Air:** Immediately move the person to a well-ventilated area, away from the source of the gas or fumes.
* **Open Windows and Doors:** Ventilate the area to remove the toxic substance.
* **Check for Breathing:** If the person is not breathing, begin CPR. If you are not trained in CPR, follow the dispatcher’s instructions.
* **Seek Medical Attention:** Even if the person seems to recover quickly, seek medical attention to rule out any long-term effects.

#### Absorption (Skin Contact)

* **Remove Contaminated Clothing:** Immediately remove any clothing that has come into contact with the substance.
* **Flush the Skin with Water:** Thoroughly rinse the affected area with copious amounts of water for at least 15-20 minutes. Use soap if available.
* **Eye Exposure:** If the substance has come into contact with the eyes, flush them with water for at least 20 minutes. Hold the eyelids open to ensure thorough rinsing. Seek immediate medical attention.
* **Seek Medical Attention:** Depending on the substance and the severity of the exposure, seek medical attention.

#### Injection

* **Remove the Stinger (If Applicable):** If the poisoning is due to an insect sting, carefully remove the stinger by scraping it away with a credit card or other flat object. Avoid squeezing the stinger, as this can release more venom.
* **Wash the Area:** Clean the injection site with soap and water.
* **Apply a Cold Compress:** Apply a cold compress or ice pack to the area to reduce swelling and pain.
* **Elevate the Limb:** If possible, elevate the affected limb to help reduce swelling.
* **Monitor for Allergic Reactions:** Watch for signs of an allergic reaction, such as hives, difficulty breathing, swelling of the face, lips, or tongue. If these symptoms occur, administer epinephrine (if available) and seek immediate medical attention.
* **Seek Medical Attention:** Seek medical attention for any injection poisoning, especially if it involves venomous creatures or drug overdoses.

### 4. Gather Information:

* **Collect Evidence:** If possible, collect any evidence related to the poisoning, such as the container of the substance, any remaining material, or any vomit. This information will be helpful for medical professionals.
* **Document Symptoms:** Keep track of the person’s symptoms and any changes in their condition. This information can help medical personnel assess the severity of the poisoning and determine the appropriate treatment.

### 5. Monitor Vital Signs:

* **Check Breathing:** Continuously monitor the person’s breathing. If they stop breathing, begin CPR.
* **Check Pulse:** Monitor the person’s pulse. If they have no pulse, begin CPR.
* **Level of Consciousness:** Monitor their level of consciousness. Are they becoming more or less alert?

## What NOT to Do When Treating Poisoning

* **Do NOT Induce Vomiting Without Instructions:** As mentioned earlier, inducing vomiting can be harmful. Always consult with the Poison Control Center or emergency medical personnel first.
* **Do NOT Give Anything by Mouth to an Unconscious Person:** Giving food or fluids to an unconscious person can cause choking or aspiration.
* **Do NOT Use Ipecac Syrup:** Ipecac syrup was once commonly used to induce vomiting, but it is no longer recommended and can be harmful.
* **Do NOT Try to Neutralize the Poison Without Instructions:** Attempting to neutralize a poison with another substance can create a dangerous chemical reaction.
* **Do NOT Leave the Person Alone:** Stay with the person and monitor their condition until medical help arrives.

## Medical Treatments for Poisoning

Medical treatments for poisoning vary depending on the substance involved and the severity of the poisoning. Some common treatments include:

* **Activated Charcoal:** Activated charcoal is a substance that can bind to many poisons in the digestive tract, preventing them from being absorbed into the bloodstream. It is often administered orally or through a feeding tube. However, it is not effective for all types of poisons (e.g., alcohol, metals, or corrosive substances).
* **Antidotes:** Specific antidotes are available for certain types of poisoning. For example, naloxone (Narcan) is an antidote for opioid overdoses, and acetylcysteine is an antidote for acetaminophen (Tylenol) overdoses. Antidotes are typically administered by medical professionals.
* **Gastric Lavage (Stomach Pumping):** Gastric lavage involves inserting a tube into the stomach to remove the contents. This procedure is less commonly used now than in the past and is typically reserved for cases where a large amount of a toxic substance has been ingested very recently.
* **Whole Bowel Irrigation:** This involves administering a large volume of a polyethylene glycol solution to flush the entire digestive tract. It is sometimes used for poisoning involving sustained-release medications or substances that are not well-absorbed by activated charcoal.
* **Hemodialysis:** Hemodialysis (kidney dialysis) can be used to remove certain toxins from the bloodstream. It is typically used for severe cases of poisoning involving substances that can be effectively removed by dialysis.
* **Supportive Care:** Supportive care includes measures to maintain vital functions, such as administering oxygen, providing respiratory support, managing seizures, and maintaining blood pressure.
