Shortage of Key Antibiotic for Syphilis Poses Public Health Concerns


Infectious disease experts are sounding the alarm about a shortage of a crucial antibiotic used to treat the sexually transmitted infection (STI) syphilis. The scarcity of this antibiotic, known as Bicillin L-A or penicillin G benzathine, could hinder efforts to curb the spread of the disease. With the rising number of syphilis cases in the United States, this shortage poses significant public health concerns.

Syphilis is already a major problem in the United States, with cases steadily increasing for over two decades. Shockingly, between 2017 and 2021, cases rose by nearly 75%, reaching over 176,000 reported cases in 2021, according to the U.S. Centers for Disease Control and Prevention (CDC). The situation becomes even more alarming considering the recent announcement from Pfizer, the pharmaceutical company responsible for manufacturing Bicillin L-A, about the shortage potentially extending into the next year.

The scarcity of this long-acting injectable antibiotic can primarily be attributed to the growing demand resulting from the surge in syphilis infections. Additionally, the medication can be used as an alternative to treat other infections like strep throat, particularly when amoxicillin is in short supply. The shortage of both Bicillin L-A and amoxicillin has created challenges for healthcare providers in addressing syphilis and other related infections effectively.

One of the major concerns associated with the antibiotic shortage is the impact on congenital syphilis. This form of the infection not only carries a high fatality rate but can also result in severe birth defects. Bicillin L-A is the sole recommended treatment for infected pregnant women, making it essential for their health and the well-being of their unborn children. Dr. Anita Henderson, a pediatrician in Hattiesburg, Mississippi, expressed her concerns, stating, “It worries me that these moms may not have access to lifesaving medication” (New York Times).

Disturbingly, the shortage of alternative treatments suitable for pregnant women is expected to persist for several more years. According to Dr. Jeffrey Klausner, an infectious disease expert at the University of Southern California, viable alternatives to Bicillin L-A are not currently available, exacerbating the gravity of the situation (New York Times).

Pfizer, the manufacturer of Bicillin L-A, acknowledges the urgent need to address this shortage. They estimate that it will take approximately one year to increase production by 50%, allowing for more widespread availability of the antibiotic. However, this timeline raises concerns about the immediate implications for pregnant women and other individuals at risk of syphilis.

To mitigate the impact of the shortage, the CDC has issued recommendations for healthcare providers. The agency advises that doctors prioritize administration of Bicillin L-A to pregnant patients and infants exposed or infected with syphilis. For others, the CDC suggests prescribing a two to four-week course of doxycycline as an alternative treatment option.

This antibiotic shortage situation is not an isolated incident but instead reflects a broader crisis of drug shortages across different areas of healthcare. The shortage of drugs extends to essential treatments, such as chemotherapy, leading to rationing and impacting patient care.

It is crucial that the pharmaceutical industry, healthcare providers, and policymakers take immediate action to address this antibiotic shortage crisis. Timely and efficient solutions are needed to ensure that individuals, especially pregnant women and their unborn children, can access lifesaving treatments. Furthermore, efforts to tackle the rising rates of syphilis must include a comprehensive approach, encompassing education, prevention, and improved access to healthcare services.
