Lemtrada Stroke and Arterial Dissection Lawsuits

In 2001, the U.S. Food and Drug Administration (FDA) approved a medication called alemtuzumab to help treat B-cell chronic lymphocytic leukemia, a type of cancer. In 2014, the same drug was approved by the FDA for the treatment of multiple sclerosis (MS).

Sanofi Genzyme soon released a version of the drug for MS patients under the brand name Lemtrada. Since Lemtrada’s release, the FDA has identified at least 13 cases of strokes and arterial tears linked to its use.

FDA Issues Black Box Warning for Lemtrada

According to the FDA, Lemtrada may increase the risk of arterial dissection, which can lead to strokes and arterial tearing in the head and neck areas of patients with multiple sclerosis. These complications most often occur shortly after receiving the drug—usually within one day—and they can lead to permanent disability or even death.

On November 29, 2018, the FDA announced the addition of a black box warning to Lemtrada packaging to increase awareness of the risk of stroke or arterial dissection after starting treatment. The black box warning is the FDA’s strictest warning and is only issued when a serious health hazard is linked to the use of a medication.

Symptoms of Stroke and Artery Tears Linked to Lemtrada

A variety of symptoms may indicate arterial dissection, which can cause stroke and arterial tearing. Signs of serious Lemtrada complications include sudden:

  • Numbness or weakness in the face, arms, or legs—especially on one side of the body
  • Confusion, trouble speaking, or difficulty understanding speech
  • Vision problems
  • Problems with walking, dizziness, or balance
  • Severe headache or neck pain

These symptoms most often appear within 1-3 days of starting Lemtrada and require emergency treatment as soon as possible.
