Guttalax (Sodium Picosulfate)

Guttalax is indicated for the temporary relief of constipation in adults and, when appropriate, in adolescents.

• Occasional constipation due to diet low in fiber.
• Bowel preparation before diagnostic procedures such as colonoscopy.
• Relief of constipation associated with travel or changes in routine.
• Use in patients who need a stimulant laxative after other measures have failed.
• Short‑term management of constipation in patients with limited mobility.
• Adjunctive therapy for constipation related to certain medications, such as opioids, when other laxatives are insufficient.
• Temporary relief of constipation during pregnancy or postpartum periods, following medical advice.

The safety profile of sodium picosulfate includes both common, usually mild, effects and rare, potentially serious reactions.

Common

• Abdominal cramping or mild pain, typically occurring within a few hours after the dose.
• Diarrhea or loose stools, which may be accompanied by increased urgency.
• Nausea or mild stomach discomfort, often transient and resolving without treatment.
• Increased frequency of bowel movements, sometimes resulting in more than three stools per day.
• Flatulence or gas, which can cause temporary abdominal bloating.

Serious

• Severe dehydration due to excessive fluid loss, which may require medical rehydration.
• Electrolyte imbalance, such as low potassium levels, that can affect heart rhythm.
• Persistent abdominal pain or rectal bleeding, indicating possible colonic irritation.
• Allergic reaction such as rash, itching, or swelling, requiring immediate medical attention.

When using Guttalax, certain precautions should be observed to minimize risks and ensure appropriate use.

• Do not use if you have an intestinal blockage, severe abdominal pain, or undiagnosed gastrointestinal disease.
• Avoid prolonged or regular use; the product is intended for short‑term relief only.
• Stay well hydrated; increase fluid intake while taking the laxative to prevent dehydration.
• Consult a healthcare professional before use if you are pregnant, breastfeeding, or have chronic health conditions.
• Keep the product out of reach of children; accidental ingestion can cause severe diarrhea.
• Discontinue use and seek medical advice if symptoms persist longer than 48 hours or worsen.

Sodium picosulfate may interact with other medicines or substances; consider the following guidance.

Avoid

• Concomitant use with other stimulant laxatives or high‑dose fiber supplements, which can increase the risk of severe diarrhea.
• Use with medications that may cause electrolyte disturbances, such as diuretics, without medical supervision.
• Avoid using Guttalax in patients receiving potassium‑sparing diuretics, as combined effect may cause hyperkalemia.

Use with caution

• Antacids containing magnesium, which can enhance the laxative effect.
• Opioid analgesics, as they may counteract the stimulant action of the laxative.
• Herbal remedies with laxative properties (e.g., senna, cascara), which could lead to additive effects.
