My father had few symptoms like losing of smell and taste, light coughing  etc. of Covid. So one of my family doctor gave him Azithromycin-500 to consume for 5 days, Histafree 120 for 5 days after dinner, Brophyle N for 10 days twice a day, Immu C plus tablet and Zincovit CL syrup and if any temperature is there then suggested him to take P 650 thrice a day My father started all the medicines from 24th April. From two days prior he has started to sense the smell and taste. But till now he has light coughing problem with some feeling of throat itiching. So does he require any more medicine? Kindly suggest me.
