Travellers should be counselled on the importance of completing the full course of treatment, particularly during and after the stay in the endemic region.
The initial trial period before travel is necessary to ensure the antimalarial is tolerated and that adequate blood levels are achieved.
Points to consider when recommending an appropriate regimen:
- Which countries are being visited?
- What is the itinerary? Which specific regions are being visited? Is it a rural or urban location?
- Who is travelling? Ages and medical history.
- What is the duration of the visit?
- Has the traveller taken the medicine before safely or have they had an adverse reaction?
- Is the recommended regimen cautioned or contra-indicated for the traveller?
- Are there any drug interactions with the traveller’s regular medication?
Use the A-Z of travel destinations to find the destination and determine the recommended regimen.
Each page contains:
- Level of risk within specific regions.
- Any specific period of risk.
- If resistance to chemoprophylaxis is present.
You need to find the specific destinations within a country to provide accurate advice; country maps are available on FitForTravel website via the links on each page.
The explanatory notes providing further clarification of the country-specific data within the chart can be found here:
Once the preferred regimen is identified you should use the chemoprophylaxis chart below to check its suitability for each traveller. Be aware that individual travellers within the same party may require different chemoprophylaxis due to their age or the presence of contra-indications or interactions.
This chart also gives you information on the dosage schedule as well as dose adjustments for children. Refer to the BNF where necessary for full details of each prophylaxis regimen.
