FDA has announced that AvKARE has issued a recall for lot # AW0221A of Atovaquone Oral Suspension USP, 750mg/5mL, due to potential contamination with Bacillus cereus. This contamination was discovered during stability testing at a third-party laboratory.

Risk Statement: The affected population, especially those individuals who are immunocompromised, face a significant risk of microbial contamination leading to severe, life-threatening infections such as endocarditis and necrotizing soft tissue infections.

Endocarditis typically caused by a bacterial infection, results in inflammation of the lining of the heart valves and chambers. Effective treatment involves a course of antibiotics or other medications over several weeks, and occasionally, surgical intervention. Swift and thorough treatment significantly increases survival rates and successful recovery, while untreated endocarditis can result in fatal outcomes.

Currently, AvKARE has not received any reports of adverse events related to this recall. However, patients are urged to take immediate action if they have the affected product.

Background: Atovaquone Oral Suspension USP is used for the prevention and treatment of Pneumocystis jiroveci pneumonia (PCP) in adults and children 13 years of age and older who are unable to tolerate other medications such as trimethoprim-sulfamethoxazole.

According to CDC under “Pneumocystis pneumonia (PCP) is a serious infection caused by the fungus Pneumocystis jirovecii. Most people who get PCP have a medical condition that weakens their immune system, like HIV/AIDS, or take medicines (such as corticosteroids) that lower the body’s ability to fight germs and sickness. In the US, people with HIV/AIDS are less likely to get PCP today than before the availability of antiretroviral therapy. However, PCP is still a substantial public health problem. Much of the information we have about PCP and its treatment comes from caring for patients with HIV/AIDS.”

The CDC explains the nomenclature of the disease. Scientists have revised both the classification and the nomenclature of this organism since its initial discovery in HIV patients during the 1980s. Previously categorized as a protozoan, Pneumocystis jirovecii is now recognized as a fungus. Initially known as Pneumocystis carinii, it was later renamed Pneumocystis jirovecii. Although the abbreviation "PJP" was considered when the name changed, the preferred abbreviation for Pneumocystis jirovecii pneumonia remains "PCP" to prevent confusion.
