I was suffering from sneezing for last one month. On 12.03.2020 I had consulted with general physician when he prescribed telekast f for 30 days. After consuming 20 tablets it is found that let has led to cause dry cough. Hence discontinued the said medicine. Instead I have been taking the syrup corex dx. For last four days but without much relief. Kindly help me with the remedy. Regardssaunak kar chaudhuri.
