Information Sources

Information on the use, benefits and risks of a number of medicines used in patients with COVID-19 are available. These should be regularly checked for updates as more information becomes available to inform choice.

The UK Royal College of Obstetricians and Gynaecologists (RCOG) guidance on Coronavirus (COVID-19) Infection in Pregnancy contains information on current therapeutic options including the IL-6 receptor inhibitors tocilizumab.

The UK Teratology Information Service (UKTIS) summary information on medications used to treat COVID-19 in pregnancy describes the available evidence on the fetal risks associated with COVID-19 treatments.

Healthcare professionals are encouraged to contact UKTIS should these agents be considered for use. This will aid the timely collection of pregnancy outcome data.

Tocilizumab

Evidence

Although data for the use of tocilizumab in pregnancy in this situation are limited, there is currently no evidence that tocilizumab is teratogenic or fetotoxic.

Guidance

Owing to the potential for COVID-19 to cause significant disease and mortality in pregnant women, the benefits of maternal treatment should be carefully considered against the fetal and/or neonatal risks.

The UK Royal College of Obstetricians and Gynaecologists current guidance is that for women meeting certain criteria the use of tocilizumab should be strongly considered.

It is recommended that any decision to treat with an IL-6 receptor inhibitor, such as tocilizumab, should be taken by a multidisciplinary team, including obstetric and infection specialists, and given if the benefits outweigh the risks. The decision, when feasible, should also be taken in discussion with the woman.

Delayed live-vaccine immunisation of new-borns

The Green Book (Chapter 6 Contraindications and Special Considerations) advises that immunisation with live vaccines should be delayed until 6 months of age in children born to mothers who received immunosuppressive biological therapy during pregnancy.

If there is any doubt as to whether an infant due to receive a live attenuated vaccine may be immunosuppressed due to the mother’s therapy, specialist advice should be sought.
