My husband was having fever and headache along with cold. Doctor gave medicines from his clinic along with azithromycin tablet and chloroquine 500 mg tablet. And doc said. To take after doing good test. He took 1 tablet after blood test. But the blood test reports says negative for malaria. So he didn't take remaining chloroquine tablets. The fever was not there for 1 day when medicines was taken given by doctor. But now the fever has came back. What may b the reason. Should he take the remaining.
