Post federal health regulators stressed that customers have ended up mistaking the medicine for a much milder stomach reliever, the manufacturer of Maalox has agreed to switch the name of its most potent medication.

On Wednesday, the Food and Drug Administration issued a warning to consumers that Maalox Total Relief contains highly potent drug ingredients that might end up causing internal bleeding. The anti-diarrhea drug is often confused with the traditional Maalox, which employs the use of a gentler formula to neutralize stomach acid.

Both the drugs can be purchased over-the-counter and buyers do not need a prescription.

"We want companies to consider the potential for name confusion when choosing names for their drugs", said Carol Holquist, FDA's Director for Medication Error Prevention.

The FDA has shared that the Swiss manufacturer Novartis will rename Maalox Total Relief and change its packaging to avoid confusion. The rebranded product should be available by September.
