Abstract:
We present two cases of phototoxic onycholysis secondary to doxycycline treatment as malaria prophylaxis. Onycholysis is a rare side-effect to treatment with doxycycline and other tetracyclines. Some physicians are unaware of this risk. Due to the increasing travel activity to malaria endemic regions, it is important to be aware of the side effects - including onycholysis - following the use of tetracyclines and it is essential to inform the patients of such effects. Spontaneous recovery follows within a few months after discontinuing the drug and there is no need for further treatment.
