Nifedipine (unlicensed indication) has been shown to be effective in suppressing pre-term labour with minimal maternal and foetal side effects. It is the first line tocolytic agent.
Salbutamol and terbutaline should only be used parenterally to suppress premature labour for up to 48 hours, between the 22nd and the 37th weeks of pregnancy and under specialist supervision with continuous monitoring of the mother and the unborn baby.
