If you need medical advice when the surgery is closed contact NHS 111 to speak to a triage nurse. Your needs will be assessed and advice offered or arrangements made for you to see a doctor.
Urgent medical treatment is provided by SELDOC (South East London Doctors On Call). They have well equipped surgeries at Lewisham and Dulwich Hospitals. You will be asked to attend there to be seen, unless you are too ill to travel by car.
N.B. If a patient's life seems at risk, call an ambulance by dialing (999).
