Gutwash 4000 Oral Laxative Liquid Sugar Free contains Polyethylene Glycol 4000 at a concentration of 10 grams per 25 milliliters, formulated to provide effective relief from occasional constipation. Polyethylene Glycol 4000 is an osmotic laxative that works by retaining water in the stool, thereby softening it and increasing bowel movement frequency without causing significant cramping or urgency. This sugar-free liquid preparation is suitable for patients requiring a laxative that does not contribute to caloric intake, making it ideal for diabetic or sugar-restricted individuals. Gutwash 4000 is indicated for the treatment of chronic constipation, fecal impaction, and for bowel cleansing prior to diagnostic procedures such as colonoscopy. The onset of action typically occurs within 24 to 72 hours after administration, and it is generally well tolerated with minimal systemic absorption. Dosage should be individualized based on patient response and clinical condition, with adherence to recommended guidelines to avoid electrolyte imbalance or dehydration. Patients are advised to maintain adequate hydration during use. Contraindications include known hypersensitivity to polyethylene glycol, intestinal obstruction, or acute surgical abdomen. Consultation with a healthcare professional is recommended before initiating therapy, especially in pediatric, elderly, or pregnant patients.
