Comments from Expert Advisory Committee

• Send MSU for culture.
• Nitrofurantion- should be avoided after 36 weeks due to risk of neonatal haemolysis.
• Fosfomycin - Recommendation for use in pregnancy remains under review pending further evidence and safety data
• Refer to local resistance patterns for empiric therapy where available and refer to MSU results. Amoxicillin resistance is common – only use if susceptibility data available.
• Review empirical treatment with results of MSU culture and susceptibility.
