U.S. Food and Drug Administration (FDA) Releases Warning About Sodium Phosphate Laxatives
An announcement from IFFGD recently alerted us to the fact that the U.S. Food and Drug Administration (FDA) recently issued expanded warnings regarding over the counter oral or rectal laxatives that contain sodium phosphate, due to increased risks of severe side effects or death in certain groups of users. Currently, labels state to take a maximum of one dose per day for three days. However, if the first dose is ineffective in relieving constipation, consumers should not continue taking the laxative product.
The updated cautions, which are not yet on product labels, now advise adults over the age of 55, as well as adults with, or caregivers of children with, kidney disease, heart disease, dehydration, colon inflammation or who are taking “diuretics or fluid medicines; angiotensin-converting enzyme (ACE) inhibitors used to lower blood pressure; angiotensin receptor blockers (ARBs) used to treat high blood pressure, heart, or kidney failure; and nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen” to consult a physician or other health care professional before using over the counter sodium phosphate-based laxatives. Such products are marketed in the U.S. under the Fleet brand name and other generic or store versions.
This change in FDA advice is the result of its review of 54 cases of serious adverse effects, including dehydration, electrolyte imbalance and kidney damage, which were ultimately fatal for 12 adults and one child in this group. As not all instances of side effects are necessarily reported to the FDA, the press release states that a precise rate of these negative outcomes is not known.
