Hello, Otrivin or Otrinose which contain xylometazoline are to be used only for sometime like 5-7 days not long as it causes more blockage and the normal cleaning activity of the skin of nose is decreased. So do try to stop its use. In place you need to take normal saline nasal spray(better will be hypertonic nasal sprays like hypertonic physiomer nasal spray) and you may also require steroid nasal spray for some time which can be tapered later. Take oral decongestant tablets in place of nasal decongestant (otrivin) which can be stopped later ....but i advice you this tablet considering you are not hypertensive. Get well soon. In case of doubt do reply.
