My husband had a bad reaction to Malarone last year, and the doctor has recommended chloroquine/proguanil which is only 70% protection. However, the chemist recommends doxycycline, but the side effects seem worse than malarone. Has anyone used doxycycline and experienced any bad reaction, eg. sickness or sensitivity to sunlight. We are keen to be fully protected, but because of his bad reaction last year he ended up taking nothing (he had bad swelling of the eyes and face) . Any comments would be appreciated.
