Hi Doctor, I am from India and here in October and November month winter season at its top. Temperature varies from 8 degree to 23 degree. In this two months, my one of a nasal got blocks, so sometime i use Othivin nasal spray. mostly I used to avoid, but if nasal blocks from long time at that time I will use it. Will it be OK, or shall I stop this. This issue is only for 2 months (Winter), rest 10 months everything will be fine. Is othivin is a drug/steroid? If i use year by year then is it making habit? Please Suggest.
