    Chloroquine is the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat. The main difference between the life cycle of P. vivax and Plasmodium falciparum P. falciparum is the development of latent forms – known as hypnozoites – in the liver. 6 The hypnozoites are not eradicated by standard antimalarials and can awaken days to months to years after the last bout of clinical malaria, in the absence of a mosquito bite, unless drugs specifically targetting the hypnozoite are administered. Plasmodium vivax is the most widespread malaria parasite. It has a dormant stage in the human liver, which makes it difficult to eradicate. It is proposed that a relapse of vivax malaria, besides being genetically determined by the specific strain, is induced by the bites of uninfected vectors.

    Does anyone know how likely it is for hydroxychloroquine to cause hair loss? Weight loss is also listed as a side effect, I am up 15 Linda 8 mo into this drug👀😤😃😁Everyone is different. I’m not ill enough to of interest to him generally! I couldn't 100 % say it is due to the mets though but my hair has gone thinner since I started taking the meds. However, Hydroxychloroquine slows down and mitigates lupus symptomatology so it will slow up hair loss. The only real side effect is on vision in those susceptible to that; annual testing for a couple of years is advisable and if that is OK you can forget visual deterioration more or less. Being on iron and B vitamins no matter what the blood tests say about levels has pretty much settled my hair down.
