Popular Muscle Relaxer Robaxin Recalled Due to Incorrect Dosing Instructions

Two lots of Robaxin (methocarbamol), a popular prescription muscle relaxer, were voluntarily recalled due to faulty dosing information on the label. Following these incorrect instructions could potentially lead to serious side effects and fatal overdose.

What is Robaxin?

Robaxin is a popular muscle relaxer. It contains methocarbamol, which is used to treat painful muscle spasms alongside other treatment methods like rest and physical therapy.

Why was Robaxin recalled?

Select lots of Robaxin were voluntarily recalled by manufacturer Endo Pharmaceuticals due to incorrect daily dosing information on the label. The label instructs patients to take “two to four tablets daily,” instead of the correct dosage of “two tablets three times daily.”

Taking too much methocarbamol can result in drowsiness, dizziness and an increased risk for falls. More serious adverse effects of a methocarbamol overdose may include seizure, coma, and even death.

Which products were recalled?

This recall affects only the following two lots of Robaxin:

• Drug: Robaxin 750 mg tablets

• Bottle size: 100 count bottle pack

• Manufacturer: Endo Pharmaceuticals

• Lots:

  • 216702P1, expiration date: September 2020

  • 220409P1, expiration date: January 2021

• National Drug Code (NDC): 52244-0449-10

To find out if your Robaxin prescription was affected by this recall, look for the lot number and expiration date on your bottle label. We created some diagrams here in case you need more help locating these numbers.
