After taking chloroquine injection ( which works for me) I am having occassional bitter taste and severe nasal congestion, please what would you advise I take?
I am not sure why you are taking chloroquine injections. Chloroquine, taken orally, can be used as a preventive drug (except in Asia where there is choroquine resistance to plasmodium falciparum) and also for treatment (along with primaquine) for malaria caused by plasmodium vivex. Chloroquine is only given by injection if the person cannot take medicine by mouth because of vomiting. Side effects of oral chloroquine include a “bitter taste in the mouth” and rarely nasal congestion. For the nasal congestion, you could try breathing steam to open the nasal passages. Unfortunately I have no suggestion for the bitter taste.
