Better

Nasal decongestants such as oxymetazoline (e.g., Afrin) nasal spray twice a day for 3 days (limit use to 3 days to prevent rebound effect); this will aid in draining of contributing sinusitis. Oral decongestants, such as pseudoephedrine 30mg every 6 hours, can be used if nasal spray is not available.

Best
