Glycerin suppositories are a form of laxative for rectal insertion, used to relieve occasional constipation. These over-the-counter products are generally for short-term relief, stimulating a bowel movement quickly.
How Glycerin Suppositories Work
Glycerin suppositories operate through a dual mechanism to facilitate bowel movements. When inserted, the glycerin draws water from the body into the intestines, which helps to soften the stool. This increase in water content makes the stool easier to pass.
Beyond softening, glycerin also acts as a mild irritant to the lining of the rectum. This local irritation stimulates the muscles in the bowel, prompting them to contract. These contractions, known as peristalsis, help to move the softened stool along and encourage evacuation.
The combination of water attraction and muscle stimulation typically leads to a bowel movement within 15 to 60 minutes after insertion. This rapid action provides quick relief.
Recommended Usage and Dosage
For adults and children aged 6 and over, the typical recommendation is one suppository per day. Children between 2 and 6 years should use a smaller, pediatric-sized suppository, also one per day. Infants under 2 years require consultation with a healthcare professional before use.
These laxatives are intended for infrequent, single doses to address occasional constipation. Using more than one suppository a day is not usually recommended unless advised by a doctor. This prevents potential side effects and reliance on the product for bowel function. Adhering to the label’s directions ensures safe and effective use.
Risks of Exceeding Recommended Dosage
Using glycerin suppositories more frequently than recommended can lead to adverse effects. These include irritation of the rectal lining, causing pain, burning, or discomfort. Excessive use can also result in abdominal cramping and diarrhea.
Frequent and prolonged use carries a risk of dehydration and electrolyte imbalance, as the suppositories draw water into the intestines. Chronic overuse can lead to a condition sometimes referred to as “lazy bowel” syndrome, where the body becomes dependent on laxatives to have a bowel movement. This reliance disrupts the body’s natural processes, making it difficult to pass stool without assistance.
When to Consult a Healthcare Professional
Glycerin suppositories are for occasional constipation relief, not a long-term solution. If constipation persists for over a week despite using suppositories, seek medical advice. Consult a healthcare professional if you experience severe abdominal pain, nausea, vomiting, or rectal bleeding.
A sudden change in bowel habits lasting over two weeks warrants professional evaluation. If a bowel movement does not occur within one hour of using the suppository, or if you have concerns about chronic constipation, a doctor can help identify underlying conditions and guide appropriate treatment.
