Glycerol Martindale Pharmaceuticals (Glycerol)

Glycerol suppositories are used primarily to alleviate constipation by softening stool and facilitating its passage through the rectum.

• Relief of occasional constipation in adults.
• Preparation for bowel evacuation before diagnostic procedures.
• Adjunct to other laxatives for enhanced effect.
• Temporary use in patients with reduced intestinal motility.
• Management of mild fecal impaction when oral agents are unsuitable.

Glycerol suppositories may cause local and systemic effects; most are mild and transient, while rare reactions can be serious.

Common

• Mild rectal irritation or burning sensation.
• Slight cramping or abdominal discomfort.
• Loose stools or mild diarrhea.
• Temporary increase in rectal discharge.

Serious

• Severe rectal bleeding.
• Persistent abdominal pain.
• Signs of allergic reaction such as rash, itching, swelling.
• Severe dehydration from prolonged diarrhea.

When using glycerol suppositories, certain precautions help minimize adverse effects and ensure safe use.

• Do not use if you have an allergic reaction to glycerol or any excipients.
• Avoid prolonged or excessive use, as it may lead to electrolyte imbalance.
• Do not insert the suppository beyond the recommended depth (approximately 2–3 cm).
• Consult a healthcare professional before use during pregnancy, lactation, or in children.
• If symptoms persist for more than 48 hours, discontinue use and seek medical advice.
• Keep the product out of reach of children.

Glycerol suppositories have limited systemic absorption, but interactions with other agents should still be considered.

Avoid

• Concurrent use with other osmotic or stimulant laxatives without medical supervision, as this may cause excessive fluid loss.
• Use with rectal preparations containing irritants that could increase mucosal damage.

Use with caution

• Antidiarrheal medications (e.g., loperamide) that may counteract the laxative effect.
• Medications that affect electrolyte balance, such as diuretics or cardiac glycosides.
• Patients on anticoagulants, due to potential for rectal bleeding if severe irritation occurs.
