What medicine should I take for nasal congestion?

Generally, the main causes of nasal congestion include environmental irritants, dry nasal passages, acute rhinitis, allergic rhinitis, and sinusitis. Patients should follow medical advice to select appropriate medications based on individual conditions, such as Compound Pseudoephedrine Hydrochloride Sustained-Release Capsules, Mometasone Furoate Nasal Spray, or Cefaclor Capsules. Detailed explanations are as follows:

1. Environmental Irritation

Exposure to cold air, dust, or irritating gases can stimulate the nasal mucosa, causing vasoconstriction followed by congestion and swelling of the mucous membrane, leading to nasal congestion, often accompanied by nasal itching and sneezing. A physiological seawater nasal spray can be used to rinse the nasal passages, remove irritants, and relieve mucosal discomfort.

2. Dry Nasal Passages

Low humidity and insufficient water intake can cause dryness of the nasal mucosa, reduced secretion, and narrowing of the nasal passage, resulting in nasal congestion, possibly accompanied by a burning sensation in the nose. Menthol Compound Nasal Drops can be used to moisturize the nasal mucosa, or a physiological seawater nasal spray can help maintain nasal moisture.

3. Acute Rhinitis

Viral infections can cause acute rhinitis. Inflammation leads to congestion and edema of the nasal mucosa, with increased secretions blocking the nasal passages, causing nasal congestion often accompanied by runny nose and sore throat. Under a doctor's guidance, medications such as Compound Pseudoephedrine Hydrochloride Sustained-Release Capsules or Amoxicillin Capsules can be used for symptom relief.

4. Allergic Rhinitis

Exposure to allergens such as pollen or dust mites activates the immune system, causing nasal mucosal edema, resulting in nasal congestion accompanied by nasal itching, paroxysmal sneezing, and clear nasal discharge. Under a doctor's guidance, medications such as Loratadine Tablets, Mometasone Furoate Nasal Spray, or Azelastine Hydrochloride Tablets can be used to reduce nasal mucosal inflammation and edema, thereby improving airflow.

5. Sinusitis

Bacterial infection causes sinusitis, with accumulation of purulent secretions in the sinuses, which compresses the nasal mucosa, causing nasal congestion accompanied by thick nasal discharge, headache, and reduced sense of smell. Under a doctor's guidance, medications such as Cefaclor Capsules, Cefuroxime Axetil Tablets, or Eucalyptus Oil and Piperonyl Butoxide Soft Capsules can be used for improvement.

In daily life, it is important to maintain indoor air humidity and avoid long-term exposure to dry or polluted environments; wear a mask when going outdoors to reduce contact with allergens and irritants; drink plenty of water to keep nasal mucosa moist; and regularly clean the nasal passages to reduce secretion buildup and lower the likelihood of nasal congestion.
