Injection penicillin recalls pose potential threats to syphilis progress

In recent news, Pfizer, the sole supplier of Bicillin L-A, a crucial drug used for treating syphilis in pregnancy, has announced a delivery of pediatric doses expected in October [1]. However, the drug has been in shortage since 2023, leaving healthcare providers scrambling for alternatives.

Bicillin L-A is essential because it reliably crosses the placenta, treating both the pregnant person and the fetus, thereby preventing congenital syphilis [3]. There is no equally effective alternative to penicillin for pregnant individuals; doxycycline and other non-penicillin antibiotics are contraindicated in pregnancy due to safety concerns for the fetus [2].

During shortages, public health authorities emphasize strict prioritization of remaining supplies for the highest-risk groups, including pregnant individuals, babies with congenital syphilis, and sexual partners of pregnant individuals [2]. Doxycycline, which is sometimes used in non-pregnant adults for early syphilis (not recommended for late latent syphilis), is not a safe or acceptable alternative during pregnancy due to its association with fetal harm [2].

If Bicillin L-A is truly unavailable, there is no recommended alternative antibiotic for treating syphilis in pregnancy. In such rare, critical situations, consultation with a maternal-fetal medicine specialist, infectious disease expert, and public health authority is essential to explore all possible options [2].

A summary table outlines the treatment options for syphilis in pregnancy:

| Patient Population | Treatment of Choice | Alternative Options | Notes | |----------------------|-------------------------|--------------------|------------------------------------------------------------| | Pregnant individuals | Penicillin (Bicillin L-A)| None (consult ID/MFM) | Doxycycline contraindicated; no safe, effective alternative[2] | | Non-pregnant adults | Penicillin | Doxycycline | Doxycycline not for late latent syphilis[2] |

Pfizer has advised customers that it will provide an update on the Bicillin supply no later than mid-August [1]. Until stock has fully recovered, Pfizer will ration available supplies of the shots, and providers will have to fill out medical request forms to receive them [1].

The National Coalition of STD Directors is gathering information from its members to understand the impact of the Bicillin recall [4]. There are concerns that cuts to funding for national and local STD programs may lead to a drop in testing for syphilis [5]. The CDC had previously posted recommendations for caring for syphilis patients during the shortage, but this information has since been taken down [5].

The US Department of Health and Human Services has referred questions about the recall and potential supply problems to Pfizer [6]. The University of Utah Health's hospital system finds it difficult to use imported products due to unrecognized bar coding and differences in product mixing and dilution [7]. One state returned about 800 vials of Bicillin to Pfizer, indicating a widespread impact of the recall [8].

Healthcare providers are managing the Bicillin shortage by being selective about who receives Bicillin shots and have not had to use imported products yet [9]. The hospital system emphasizes the importance of strict prioritization of remaining supplies for the highest-risk groups [2].

In conclusion, during the Bicillin L-A shortage, penicillin remains the only acceptable treatment for syphilis in pregnancy. Healthcare providers must prioritize penicillin for pregnant patients and work closely with public health and specialty services to secure supplies. In rare cases where access is severely limited, consultation with experts is critical.
