QUESTION
We had a weekend in the Kruger Park and all of us took anti malaria pills beforehand. None of us was bitten or even saw a mosquito, do we need to carry on taking them for so long?
ANSWER
Since you say “so long”, I assume you are either taking doxycycline or Lariam, both of which are taken for four weeks after leaving the malarial area. Unless you are experiencing severe side effects, it is always recommended to continue taking prophylactic medication for the full course, the reason being that the malaria parasite has a latent period of up to a few weeks, and the prophylactics only kill the parasite after this latent stage. Even though you didn’t see any mosquitoes, the possibility remains that you got bitten and did not notice – ultimately, you can weigh up the slight inconvenience of taking the pills for a while longer versus the slight risk, but enormous inconvenience of getting malaria!
Since you have taken malaria prophylactics, please take a moment to fill out the Malaria Medication Side-effects Survey: Treatment and Prophylaxis!
Thank you!
