The first thing to consider is whether the runny nose is caused by chronic rhinitis, sinusitis and allergic rhinitis. Chronic rhinitis and sinusitis are firstly treated conservatively, mainly with medication, you can take oral medication for rhinitis, such as Cangzhi Rhinitis Drops or Rhinitis Ning Capsules, together with the drug Cerno or Mucosolvan to promote discharge. If it is caused by chronic sinusitis, it can also be combined with antibiotics, amoxicillin capsules or erythromycin capsules. If the runny nose is caused by allergic rhinitis and may be accompanied by nasal itching and sneezing, the main focus is on anti-allergic drugs, which can be taken orally as cetirizine hydrochloride or stavastine hydrochloride, together with anti-leukotriene anti-allergic drug montelukast sodium tablets.
