LA CROSSE, Wis. (WKBT) -

The U-S Food and Drug Administration is asking drug manufacturers to limit the strength of acetaminophen in prescription drug products. These products are typically a combination of acetaminophen and an opioid.

Acetaminophen will be limited to 325 milligrams per dose in prescription medication. The change would make these products safer for patients if they use them in combination with over-the-counter acetaminophen.

"By lowering the amount in the tablets the FDA is trying to make it where we're going to be less likely to push over that threshold," said Kimberly Lansing, a doctor at Gundersen Health System in La Crosse.

A warning highlighting the potential for severe liver injury and allergic reactions is being added to the label of all prescription drug products that contain acetaminophen.

All over-the-counter products containing acetaminophen are not affected by this action. Safety measures related to over-the-counter acetaminophen products will be addressed separately.
