Knee Injection Drug Recalled for Contamination

Knee Injection Drug Recalled for Contamination | Pintas & Mullins Law Firm

American biotech company Sanofi Genzyme voluntarily recalled a lot of over 12,000 Synvisc-One (hylan G-F 20) syringes on December 11, 2017.

Synvisc-One is a drug to relieve knee pain in patients with osteoarthritis. The gel inside the syringe is reportedly contaminated with certain microbes that may increase patients’ risk of infection.

Sanofi revealed that the microbes are resistant to many antibiotics and are, therefore, difficult to treat. 


Osteoarthritis is a chronic condition in which joints deteriorate over time. This “wear-and-tear” arthritis often develops as a person ages, but it can also be hereditary or due to other illnesses or repetitive injuries.

Various treatments alleviate pain and return mobility, but there’s no cure.


Synvisc-One is prescribed to patients who haven’t responded well to other medications.

The medication contains hyaluronic acid, a substance that absorbs shock and lubricates joints. While naturally present in healthy joints, the substance seems to break down in osteoarthritis patients.

Patients find that injecting the medication into their knees eases the pain and inflammation they feel from their arthritis. 


This isn’t the first time the biotech giant is in the news.

In December 2015, one of the company's chemotherapy drugs, Taxotere, was given the FDA’s most severe warning after it was found to cause permanent hair loss.

Although hair loss is a common side effect of many chemotherapy drugs, Taxotere may prevent patients’ hair from ever growing back.
