Laxido Sinaasappel (Sodium Hydrogen Carbonate, Potassium Chloride, Sodium Chloride, Macrogol 3350)

Laxido Sinaasappel, an osmotic laxative, is indicated for conditions characterized by hard stool or reduced bowel motility.

• Constipation: softens stool and promotes regular bowel movements in patients with functional or chronic constipation.
• Opioid‑induced constipation: alleviates reduced intestinal transit caused by opioid therapy, improving stool frequency and consistency.
• Chronic idiopathic constipation: enhances stool frequency and reduces straining in adults with long‑term constipation unresponsive to diet.

• Macrogol 3350 is a high‑molecular‑weight polyethylene glycol that is minimally absorbed from the gastrointestinal tract. It exerts an osmotic effect by retaining water within the intestinal lumen, increasing stool water content and volume. The resulting softening of stool and distension of the colon stimulate peristaltic activity, facilitating the passage of feces without altering electrolyte balance significantly. The formulation also contains sodium hydrogen carbonate, potassium chloride and sodium chloride to maintain isotonicity.

Laxido Sinaasappel may be associated with several adverse reactions, most of which are mild and transient.

Common Side Effects

• Abdominal bloating: feeling of fullness or swelling in the abdomen.
• Flatulence: increased gas production leading to passing of wind.
• Nausea: sensation of unease and urge to vomit.
• Diarrhea: loose, watery stools occurring more frequently.

Serious or Rare Side Effects

• Severe electrolyte imbalance: abnormal sodium or potassium levels that may cause cardiac issues.
• Allergic reaction: rash, swelling, itching, or anaphylaxis requiring immediate medical attention.
• Persistent abdominal pain or rectal bleeding: ongoing pain or blood in stool indicating possible complications.
• Dehydration: excessive fluid loss leading to dizziness or low blood pressure.

Before initiating Laxido Sinaasappel, consider the following precautions to ensure safe use.

• Assess renal function: evaluate kidney performance as fluid shifts may affect patients with renal impairment.
• Monitor electrolytes: check sodium and potassium levels during prolonged therapy to prevent imbalance.
• Use with caution in the elderly: older adults have higher risk of dehydration and electrolyte disturbances.
• Avoid in bowel obstruction: drug requires a patent gastrointestinal tract to function safely.
• Pregnancy and breastfeeding: consult a healthcare professional before use, as safety data are limited.
• Store at ambient temperature: keep in original packaging, protect from moisture and heat.

Laxido Sinaasappel can interact with other medicines; awareness of major and moderate interactions helps prevent adverse outcomes.

Major Interactions (Avoid)

• Diuretics: concurrent use may exacerbate fluid and electrolyte loss, increasing risk of dehydration.
• Magnesium‑containing laxatives: additive osmotic effect can lead to excessive fluid loss and electrolyte disturbances.
• Anticholinergic agents: may reduce gastrointestinal motility, diminishing the laxative’s effectiveness.

Moderate Interactions (Monitor Closely)

• Oral rehydration solutions: monitor fluid balance to avoid over‑correction of electrolytes.
• Warfarin: changes in plasma volume may affect INR; regular monitoring is advised.
• Antibiotics (e.g., tetracycline): may alter gut flora and affect stool consistency; observe clinical response.
