emergency standby treatment
Seek expert advice
Emergency standby treatment should be recommended for those taking chemoprophylaxis and visiting remote areas where they are unlikely to be within 24 hours of medical attention.
- used in travellers who believe that they may have malaria (not as a replacement for chemoprophylaxis)
- started in instances where it is impossible to consult a doctor and/or reach a diagnosis within 24 hours of the onset of fever.
- written instruction should be given to the traveller to ensure appropriate use e.g. - symptoms suggesting possible malaria, including fever of 38°C and above, indications for starting the standby treatment, how to take it, expected side-effects and the possibility of drug failure
- medical attention should be sought as soon as possible for full assessment and to exclude other serious causes of fever
- drugs used for emergency standbytreatment should differ from the chemoprophylaxis agents in order to minimise drug toxicity and due to concerns over drug resistance
Standby treatment course should be completed and antimalarial cheoprophylaxis should be recommenced 1 week after taking the first treatment dose. Exception to this is in the case of mefloquine prophylaxis, which should be resumed at least twelve hours after the last treatment dose if quinine was used for standby treatment
If vomiting occurs:
- within 30 minutes taking the standby treatment dose - a second full treatment dose of the antimalarial should be taken
- after 30-60 minutes - half-dose
Antipyretics should be used to treat fever.
