Unfortunately, after suffering from allergic rhinitis, it is necessary to choose drugs for treatment as soon as possible. Generally speaking, there are two kinds of anti-allergic drugs, external medicine and internal medicine. Generally speaking, for allergic rhinitis, it is often more effective to choose external drugs than oral drugs.

However, I believe everyone knows the truth that every drug has three kinds of toxicity. When choosing a therapeutic drug, you must consult your doctor in advance and choose the appropriate drug at the doctor's suggestion. Don't abuse drugs, or it will be endless.

Patients with allergic rhinitis can mainly take antihistamines and vitamin C preparations for treatment, and generally can choose to take drugs such as loratadine tablets or diphenhydramine tablets. If the symptoms of nasal congestion and runny nose are too serious, glucocorticoid and leukotriene receptor antagonist can be taken in small doses as appropriate, and the principle of combined medication can be followed.

2. Intranasal administration

Patients can wash their nasal cavity with normal saline when nasal congestion occurs, and then use nasal decongestant for treatment.
