What to Do if Silica Gel Is Eaten

Silica gel is a desiccant, meaning that it is used to absorb moisture in products such as crackers and shoes; this helps prevent odors and spoilage. It is made from activated carbon and silicon dioxide, or sand, and was patented in 1919 for use in military and medical applications. It is not poisonous; however, ingestion can cause some mild side effects.

  1. Safety

    • The FDA has designated silica gel as generally recognized as safe (GRAS). Despite the warnings on silica gel packets, the West Virginia Poison Control Center's website reassures that silica gel is nontoxic. Even in cases when the silica gel is coated with a moisture indicator, such as the carcinogenic cobalt (II) chloride, there is not enough to cause health problems, according to Mike Yudizky of the North Texas Poison Control Center. Swallowing silica gel is not an emergency and does not warrant a call to the Poison Control Center or a trip to the emergency room.

    Side Effects

    • Silica gel can produce some side effects in humans and pets. The main problem is an upset stomach. This is usually mild and does not last long. The best thing you can do for someone who has swallowed silica gel is to treat the discomfort of an upset stomach. Keep him hydrated, especially if he is vomiting or gets diarrhea. Pets may have natural ways of dealing with an upset stomach; dogs, for example, often eat grass to induce vomiting. Keep them hydrated, as you would a human, feed them bland food and take them to a vet if the condition worsens.

    Complications

    • The biggest hazard that can occur from eating silica gel packets is choking. If this happens, you must be able to act quickly. To perform the Heimlich maneuver, wrap your hands around the choking persons' ribcage from behind, make a fist and cover it with your other hand, and make quick upward thrusts between the ribcage and the navel. For infants, lay them on their back and perform upward thrusts between the ribcage and the navel using two fingers. Another potential hazard is intestinal obstruction, which might occur if small animals eat very large quantities of silicon gel. If you suspect this has occurred, consult your vet.
