Isopropyl alcohol (IPA), also referred to as isopropanol, is a chemical that’s commonly found in rubbing alcohol, hand sanitizers, and certain cleaning products. IPA poisoning occurs when the liver is no longer able to manage the amount of IPA in the body.
Ingestion of IPA may be accidental or deliberate. IPA causes rapid intoxication, so people sometimes drink it to get drunk. Other people use it to attempt suicide.
Symptoms may appear immediately or may take a few hours to become noticeable. IPA poisoning usually causes:
- stomach pain
- slowed breathing
In severe cases, it can lead to a coma.
IPA poisoning requires immediate medical attention. Call 911 or go to an emergency room right away if you suspect that you or someone you know has IPA poisoning.
The symptoms of IPA poisoning vary by the type and extent of poisoning. Sometimes, the symptoms may not appear for several hours.
The symptoms of IPA poisoning include:
- low blood pressure
- stomach pain
- rapid heart rate, or tachycardia
- low body temperature
- slurred speech
- slow breathing
- unresponsive reflexes
- throat pain or burning
Your body can handle small amounts of isopropyl alcohol. In fact, your kidneys remove approximately 20 to 50 percent of IPA from your body. The rest is broken down into acetone by enzymes known as alcohol dehydrogenases. This acetone is filtered out of your body through the lungs or kidneys.
However, when you ingest more IPA than your body can manage (which occurs around 200 mL for an adult), poisoning can occur.
The abuses of isopropyl alcohol that may lead to poisoning include ingestion and inhalation:
- IPA can make people feel drunk, so some people buy products containing IPA and drink them on purpose.
- IPA is the main ingredient in many household cleaning products. Since these products are easily available, some people may choose to drink them or inhale them when they want to commit suicide.
People who take antidepressants may get IPA poisoning more easily than others. Certain antidepressants increase the effects of IPA, so even a small amount can be poisonous. A class of antidepressants called monoamine oxidase inhibitors (MAOIs) can cause a particularly dangerous reaction.
Children are also more prone to IPA poisoning. They often chew on objects and drink products that they find around the house. This is why it’s important to put anything containing IPA out of the reach of children.
Your doctor will perform a physical exam so they can check your vital signs and look for signs of IPA exposure, such as skin damage.
During the exam, your doctor may ask you the following questions:
- How did the poisoning occur? Did you drink the product or did you spill it on yourself?
- What was the source? What specific product did you ingest?
- What was the intent? Was it taken on purpose?
- What medications are you taking? Was there ethyl alcohol in the product?
Your doctor may also order the following blood tests to help make a diagnosis:
- a complete blood count (CBC) to look for signs of infection or damage to your blood cells
- a serum electrolyte level to see if you’re dehydrated
- a toxicity panel to determine the concentration of IPA in your blood
In some cases, your doctor may run an electrocardiogram (EKG) to assess your heart function.
The goal of treatment is to remove the alcohol from your body and to keep your organs working properly. Treatment for IPA poisoning can include:
To prevent poisoning, avoid swallowing any products containing IPA. Among other things, this includes:
- most household cleaning products
- paint thinners
- rubbing alcohol
Keep these items out of the reach of children.
It’s also important to wear gloves and avoid inhaling fumes when using certain products with IPA, such as cleaning products. People who work in laboratories or factories that use IPA should be particularly cautious as well. Repeated skin exposure to IPA in large amounts can lead to poisoning.
You should never induce vomiting because this can further damage your esophagus. However, there are steps you should take when you or someone you know has IPA poisoning:
- Drink plenty of water. This can help your body flush out the toxin. However, you shouldn’t do this if you have symptoms that make it difficult to swallow, such as throat pain or decreased alertness.
- If the chemical is on the skin or eyes, rinse the area with water for 15 minutes.
- Call 911 or go to the emergency room immediately.
