Movicol Sabor Naranja (Sodium Hydrogen Carbonate, Potassium Chloride, Sodium Chloride, Macrogol 3350)

Movicol Sabor Naranja, an osmotic laxative, acts on the gastrointestinal tract to relieve constipation.

• Constipation: softens stool and promotes regular bowel movements in patients with chronic or functional constipation.
• Occasional constipation: provides rapid relief of infrequent constipation episodes without the need for prescription medication.
• Chronic idiopathic constipation: assists long‑term management by maintaining stool softness and regularity in adults.

• Polyethylene glycol 3350 exerts its laxative effect through osmotic activity. The high‑molecular‑weight polymer is poorly absorbed, retaining water within the intestinal lumen. This increases intraluminal fluid volume, softens fecal mass, and stimulates peristalsis, facilitating the passage of stool. The effect is localized to the gut and does not involve systemic absorption. It does not alter electrolyte balance significantly when used as directed and its action is confined to the gastrointestinal tract.

Polyethylene glycol 3350 may cause adverse reactions, most of which are mild and transient.

Common Side Effects

• Abdominal bloating: feeling of fullness or swelling in the abdomen.
• Nausea: mild to moderate sensation of wanting to vomit.
• Flatulence: increased intestinal gas.
• Abdominal pain: cramping or discomfort in the stomach area.
• Diarrhoea: loose or watery stools.

Serious or Rare Side Effects

• Severe electrolyte imbalance: abnormal levels of sodium, potassium or chloride.
• Dehydration: excessive loss of body fluids.
• Allergic reaction: rash, itching, swelling or difficulty breathing.
• Severe abdominal pain: persistent or worsening pain.
• Rectal bleeding: presence of blood in stool.

When using Movicol Sabor Naranja, consider the following precautions to ensure safe and effective use.

• Renal function assessment: evaluate kidney function before initiating therapy in patients with renal impairment.
• Electrolyte monitoring: check serum electrolytes periodically, especially in long‑term use or high‑dose regimens.
• Elderly patients: use with caution in older adults due to increased risk of dehydration.
• Intestinal obstruction: avoid use in patients with known or suspected bowel blockage.
• Dosage adherence: do not exceed the prescribed amount or frequency without medical advice.
• Store at ambient temperature: keep below 25 °C, in the original container, protected from moisture and direct sunlight.

Polyethylene glycol 3350 can interact with certain medications; awareness of these interactions helps prevent adverse effects.

Major Interactions (Avoid)

• Concurrent osmotic laxatives: combined use may cause severe fluid and electrolyte disturbances.
• Diuretics: increased risk of dehydration and electrolyte imbalance when used together.
• ACE inhibitors or ARBs: potential for additive effects on potassium levels.

Moderate Interactions (Monitor Closely)

• Antacids: may alter the gastrointestinal environment and affect laxative efficacy.
• NSAIDs: concurrent use can increase risk of gastrointestinal irritation.
• Mineral supplements (e.g., potassium chloride): may enhance electrolyte changes.
