Get Fleet Online

Fleet (sodium phosphate) is used to relieve occasional constipation and to cleanse the bowel before a colonoscopy, surgery, or other medical procedure. It works by pulling water into the colon, which softens stool and triggers a bowel movement, typically within 1 to 5 minutes for the enema form or within a few hours for the oral form.

Fleet is available in enema and oral solution forms. The enema is administered rectally and is used for quick relief of constipation. The oral solution is taken with large amounts of water as directed by your physician. Never exceed the recommended dose, as overuse can cause serious electrolyte imbalances.

Fleet is not appropriate for people with kidney disease, congestive heart failure, bowel obstruction, or certain electrolyte disorders. It should also be used with caution in older adults and people taking medications that affect kidney function or electrolytes. Your Doctronic physician will review your history to confirm it is safe for you.

Common side effects include bloating, cramping, nausea, and diarrhea. More serious but rare risks include dehydration and electrolyte shifts, particularly low phosphate, potassium, or sodium levels. Drinking adequate fluids as directed reduces these risks. Contact a healthcare provider if you experience severe abdominal pain, vomiting, or no bowel movement after use.

Fleet works more quickly than most other laxatives because it draws a large volume of water into the colon rapidly. MiraLax (polyethylene glycol) is gentler and often preferred for chronic constipation. Senokot (senna) stimulates the bowel muscles. Your physician will recommend the most appropriate option based on your symptoms and medical history.

Fleet sodium phosphate is intended for occasional or procedural use and is not recommended for regular long-term treatment of chronic constipation due to the risk of electrolyte disturbances. For ongoing constipation, your physician may recommend a different laxative class, dietary changes, or further evaluation.
