IF YOU’RE GOING TO A MALARIA ZONE…

Most British tourists entering a malarial zone this summer will be prescribed one of three antimalarials, says Prof David Lalloo, director of the Liverpool School of Tropical Medicine. These are: doxycycline; Malarone (known scientifically as atovaquone plus proguanil); or Lariam (mefloquine).

Malarone is the most popular option because its patent has recently expired. Doxycycline should not be taken by children under 12 or pregnant women, because it may affect bone growth. If possible, pregnant women should avoid any antimalarials during their first trimester.

Antimalarials should ideally be taken on a full stomach to avoid side effects, especially doxycycline, says Prof Lalloo.

It is important to follow the instructions: studies suggest only 20 per cent of travellers take antimalarials as often as they should.

All antimalarials have side effects. Doxycycline and Malarone can cause stomach upset, nausea, headaches, skin irritation and mouth ulcers. Lariam has been linked with insomnia, anxiety, panic attacks, and even

hallucinations.

If you are taking Lariam and think you are experiencing psychological side effects, Prof Lalloo says you may wish to seek medical advice, and investigate an alternative, but this should be weighed against the malaria risk where you are.

Always seek advice from a specialist travel clinic or a GP with expertise in travel medicine before travelling.
