Pfizer will run out of several doses of penicillin, which treat syphilis, strep throat, and other infections, later this year as shortages ripple across the US supply chain.
The company anticipates running out of the children’s dose of the syphilis drug Bicillin L-A by the end of June, according to a letter Pfizer posted Tuesday on the Food and Drug Administration’s website. The company says it’s prioritizing production of larger doses of Bicillin L-A, which is recommended for pregnant people with syphilis because it is the only drug that can pass through the placenta and also treat the fetus.
A different Pfizer penicillin, Bicillin C-R that treats other bacterial infections but not syphilis, is expected to run out in the third quarter, which ends Sept. 30. Pfizer’s penicillin has been in shortage since April.
“The supply interruption is the result of a complex combination of factors including significant increases in demand, due to an increase in syphilis infection rates as well as competitive shortages,” Pfizer said in the letter, which is dated June 12.
