Glycerin suppositories are a form of hyperosmotic laxative used for the rapid relief of occasional constipation. These small, solid inserts are designed for rectal administration, where they melt at body temperature to release the active ingredient, glycerol. The primary action involves drawing water from the surrounding tissues into the lower intestine, a process that softens the stool and adds bulk. This influx of moisture helps to lubricate the stool, easing its passage. Additionally, the glycerol mildly stimulates the muscles in the rectal area, promoting the contractions necessary for a bowel movement.
Step-by-Step Application Guide
Proper application ensures both the safety and effectiveness of the suppository. Begin by washing your hands thoroughly with soap and warm water both before and after handling the medication. Unwrap the suppository completely. If it feels too soft, chill it in the refrigerator briefly or run cold water over it while still in the wrapper.
To aid insertion, moisten the pointed tip of the suppository with tap water or a water-based lubricating jelly. Avoid using petroleum jelly, as this can interfere with the suppository’s action. Position yourself comfortably, typically by lying on your side with the lower leg straight and the upper leg bent toward your stomach.
Gently insert the pointed end of the suppository into the rectum, pushing it in about one inch, to ensure it is past the anal sphincter. After insertion, remain lying down for 15 to 20 minutes to allow the suppository to dissolve and begin working effectively. Attempt to resist the urge to have a bowel movement for this retention period if possible, as this maximizes the stimulating and softening effects of the glycerol.
Dosage and Timing Guidelines
Glycerin suppositories are intended for single-use relief of temporary constipation. For adults and children six years of age and older, the standard dosage is one adult-sized suppository administered rectally once daily as needed. Pediatric dosing for younger children, especially those under the age of two, should be determined in consultation with a healthcare provider.
The onset of action is fast, usually producing a bowel movement within 15 to 60 minutes after insertion. Because of this rapid effect, use the suppository when you have easy access to a restroom. Do not use the product for more than one week unless specifically advised to do so by a doctor.
Safety Precautions and Contraindications
While generally safe for occasional use, avoid this product if you are experiencing severe abdominal pain, nausea, vomiting, or a fever. These symptoms can indicate a more serious underlying condition like appendicitis or a bowel obstruction. The suppository should also not be used if you have a known allergy to glycerin or if you are dealing with unexplained rectal bleeding.
Frequent or prolonged use of any laxative can lead to laxative dependence, where the bowel loses its ability to function normally without assistance. If constipation persists or worsens after one week of use, or if you do not have a bowel movement within one hour of administration, seek medical attention.
Common Effects and Minor Side Effects
After successful administration, the most immediate and expected effect is a strong urge to defecate, which indicates the treatment is working. Users may also notice some common, minor side effects that do not require urgent medical attention. These can include a mild burning sensation or temporary irritation in the rectal area immediately following insertion.
Some individuals may experience abdominal discomfort, cramping, or increased gas as the bowel begins to contract and empty. Small amounts of mucus in the stool or tenesmus, the feeling of needing to pass a stool even when the bowels are empty, are also reported minor effects. These issues are typically brief and resolve once the bowel movement has occurred.
