Accidental ingestion of medication is a common concern, especially when it’s not intended for oral consumption. A suppository is a medication delivery system specifically designed for absorption through mucous membranes, such as those in the rectum or vagina, rather than being swallowed. While these medications are formulated for targeted delivery, unintended oral ingestion can occur. This article explains the nature of suppositories, the typical reactions if one is eaten, and when such an incident warrants immediate medical attention.
Understanding Suppositories
Suppositories are solid dosage forms that melt or dissolve at body temperature, releasing their medication for absorption. They are composed of base materials like cocoa butter, gelatin, or polyethylene glycols (PEGs), which allow them to maintain their shape at room temperature but melt once inserted into a body cavity. This design facilitates medication absorption into the bloodstream, bypassing the digestive system where stomach acids or enzymes might break down the drug. Some suppositories are for local effects, like treating hemorrhoids or vaginal infections, while others deliver medication systemically, such as fever reducers.
The unique composition and delivery method of suppositories mean they are not intended for oral intake. Unlike oral pills, which are designed to withstand stomach acid and dissolve in the digestive tract, suppositories rely on melting or dissolving in moist environments like the rectum or vagina. Swallowing a suppository can render the medication less effective, as it may not be absorbed properly or could be broken down by digestive processes.
Common Reactions to Ingestion
When a suppository is accidentally swallowed, immediate, generally non-serious reactions often occur. Many people report an unpleasant or waxy taste, primarily due to the suppository’s base material, which is not palatable or easily digestible.
Mild stomach upset, nausea, burping, or slight changes in bowel habits are also common initial symptoms. These effects are usually transient and are typically a reaction to the unfamiliar texture and non-toxic components of the suppository base. For instance, ingesting a boric acid suppository might lead to minor stomach upset, nausea, or limited vomiting.
When Ingestion Becomes Serious
The seriousness of ingesting a suppository depends largely on the specific active ingredient it contains and the amount consumed. While the base materials are generally not highly toxic, the medication within can be dangerous if taken orally, especially in large doses. Certain drugs are much more toxic when processed by the digestive system and liver than when absorbed rectally or vaginally.
For example, acetaminophen (paracetamol) suppositories, commonly used for fever and pain, can cause severe liver damage if ingested orally in toxic amounts. Nonsteroidal anti-inflammatory drugs (NSAIDs) in suppository form, such as indomethacin, can lead to gastrointestinal upset, kidney dysfunction, and, in large overdoses, central nervous system effects like seizures.
Sedative suppositories, if swallowed, can cause central nervous system depression, leading to drowsiness, confusion, or even coma, particularly if combined with other sedatives. Laxative suppositories, like those containing bisacodyl, can induce severe abdominal cramping, diarrhea, and dehydration when ingested orally. Certain types, like mineral oil, can also pose an aspiration risk.
Boric acid suppositories, though generally safe for vaginal use, can cause stomach upset, kidney problems, and potentially death if large quantities are swallowed. Children are particularly vulnerable to the toxic effects of medications due to their smaller body size and developing systems.
Symptoms indicating a serious reaction include severe or persistent vomiting, intense abdominal pain, significant drowsiness or confusion, difficulty breathing, seizures, or signs of an allergic reaction such as swelling or hives. These symptoms require immediate medical evaluation.
Steps to Take After Ingestion
If a suppository has been swallowed, accurately assess the situation. Identify the exact type of suppository, its active ingredients, and the approximate amount ingested. This information will be crucial for medical professionals.
Do not induce vomiting unless specifically advised by a medical professional. Inducing vomiting can lead to further complications, such as aspiration of the substance into the lungs, which can cause chemical burns or severe lung injury. Vomiting can also re-expose the esophagus to potentially irritating or corrosive substances, worsening any damage.
Instead, immediately contact a local poison control center, such as the national Poison Help hotline at 1-800-222-1222 in the United States. These centers are staffed by experts who can provide personalized guidance based on the specific ingredients and amount ingested. They can determine the risk level and advise on whether at-home monitoring is sufficient or if further medical attention is necessary.
Seek emergency medical attention by calling 911 or your local emergency number if the person collapses, has a seizure, experiences severe difficulty breathing, or cannot be awakened. These are signs of a severe reaction that requires immediate intervention. Closely monitor the individual for any developing symptoms, even if initial reactions are mild, and be prepared to provide all relevant details to emergency responders or poison control.
