Is it harmful to take doxycyclene for a prolonged time? My son has been in a malaria area and is going again in two months!

Is it harmful to take doxycyclene for a prolonged time? My son has been in a malaria area and is going again in two months!

Not really: There are anti malarials he could take that are not doxycycline, like Malarone (atovaquone and proguanil) and lariam. Some you take once a week for a period before, during, and after. Doxycycline should not be taken for months, but a few weeks won't cause much harm. Contact your doc and local travel clinic/ health department for malaria prophylaxis alternatives.

Not long ago my friend told me that the anti-malarial medicines can be worse than catching malaria itself. How true is this?

It's not: I'm really sorry there are such foolish people in this world. If you've never had malaria and you go to an area with there's falciparum without an anti-malarial on board, you're asking to be dead in two weeks. Is that what you want? There will always be doctor-bashers. People who take them seriously can pay with their lives.

See below: Depending on the type of malaria, some can hide out in the liver and pop out again later down the road; if you are given a medication called Primaquine to treat these (in addition the treatment for active malaria), you shouldn't have recurrences after. Multiple recurrences would suggest reinfection, especially if you live in an endemic area.
