Pregnancy, breastfeeding and fertility while having sotrovimab

Sotrovimab and pregnancy

There is little information about the use of sotrovimab in pregnancy.

It is an antibody that is likely to cross the placenta and the effect on your baby is unknown. However, similar antibodies are given during pregnancy for different reasons (such as anti-D injections depending on your blood type), and are safe.

Sotrovimab has not yet been studied in pregnancy, so the risks and benefits of the treatment for you and your baby are currently unknown. Sotrovimab has been shown to be effective at treating COVID-19 outside of pregnancy and it's likely that it will be effective during pregnancy too.

If you're pregnant, you and your baby are at greater risk from severe coronavirus (COVID-19) infection, and so you may benefit from having sotrovimab despite there being little information on its use.

Speak to your doctor who will be able to discuss whether taking this medicine is right for you, based on your health and your personal risk from COVID-19.

Sotrovimab and breastfeeding

If your doctor or health visitor says that your baby is healthy, it's OK to have sotrovimab while breastfeeding.

There is no information about whether sotrovimab gets into breast milk, but it would only be expected to pass through in tiny amounts.

Your baby will not be able to absorb a lot of this medicine from your breast milk into their body, and so it's unlikely to cause any side effects in your baby.

You can continue to breastfeed if you have COVID-19.

If you notice that your baby is not feeding as well as usual, or if you have any other concerns about your baby, then talk to your health visitor, midwife, pharmacist or doctor as soon as possible.

It's not known whether having sotrovimab will affect fertility in either men or women.
