What a glycerin suppository does
Glycerin suppositories are a mild, short-term remedy for constipation. Glycerin draws water into the rectum and lubricates and stimulates the bowel, usually producing a bowel movement within 15–30 minutes.
Supplies you may need
- Glycerin suppository (check the package for age-specific product and dose)
- Clean tissue or washcloth
- Warm water (or a water-based lubricant if needed)
- Gloves (optional, for caregiver use)
- Soap and water to wash your hands
Step-by-step instructions
- Read the package and label. Follow manufacturer directions and any instructions from your healthcare provider. Do not use a suppository that is damaged or expired.
- Wash your hands thoroughly with soap and water.
- Unwrap the suppository at the pointed end. If it’s soft because of warmth, you can chill it briefly in the refrigerator (do not freeze) so it’s firmer for insertion.
- Optional: moisten the tip with a little warm water or a water-based lubricant. Avoid getting lubricant on medication instructions or packaging.
- Get into a comfortable position for insertion. Common positions:
- Lying on your left side with your right knee pulled toward your chest (left lateral position).
- Lying on your back with knees bent and feet flat.
- Standing with one foot on a low stool and leaning forward.
- Gently push the suppository, rounded/pointed end first, into the rectum:
- Adults: insert about 1 to 1.5 inches (2.5–3.8 cm) past the anal opening.
- Children: generally about 1/2 inch (≈1.3 cm); follow the package or a doctor’s instructions.
- Infants: usually about 1/4 to 1/2 inch; always check the product label or ask a clinician before use in young infants.
- Hold the buttocks together briefly (a few seconds) to help keep the suppository in place, then relax.
- Remain lying or still for 10–15 minutes if possible so the suppository dissolves and begins to work. The urge to have a bowel movement usually occurs within 15–30 minutes.
- When finished, wash your hands again. Clean any small residue from the skin with warm water and a washcloth.
Aftercare and what to expect
- You may feel cramping or a strong urge to pass stool — this is normal.
- If there is no bowel movement after one dose and you are unsure, follow package directions or contact a healthcare provider before repeating the dose.
Precautions and when not to use
- Do not use if you have severe abdominal pain, nausea, vomiting, fever, or unexplained rectal bleeding — contact a healthcare provider right away.
- Talk to a clinician before giving to newborns or young infants; many products are not recommended for very young babies without medical advice.
- Do not use repeatedly for long-term constipation without medical supervision. Frequent use can cause dependence or mask an underlying problem.
- Read active ingredients and avoid if you have a known allergy to any component.
- If you have recent rectal or anal surgery, severe hemorrhoids, or inflammatory bowel disease, check with your surgeon or gastroenterologist first.
Storage and disposal
- Store suppositories as directed on the package (usually at room temperature out of direct heat; some recommend refrigeration in hot climates so they remain firm).
- Discard used or unwrapped suppositories; do not reuse.
When to call a healthcare provider
- Constipation lasts more than a week or is recurrent.
- Severe abdominal pain, fever, or vomiting occurs.
- There is rectal bleeding or black/tarry stools.
- The suppository causes irritation, swelling, or signs of an allergic reaction.
Quick tips
- Always follow the product label and any clinician instructions.
- Use the smallest age-appropriate product for children and infants and ask a clinician if you’re unsure.
- If you are uncomfortable inserting the suppository yourself, a trained caregiver or clinician can help.
If you want, tell me the age of the person who needs the suppository and any medical conditions — I can give more specific, age-appropriate guidance.
