Acute sinusitis is caused by infection. When acute sinusitis occurs repeatedly and is not cured for a long time, it can develop into chronic sinusitis. After suffering from sinusitis, you can treat it with the following medications. 1. Antibiotics. Whether it is acute sinusitis or chronic sinusitis, antibiotics can be used to treat it and have a very good effect. This drug is able to reduce inflammation and reduce the degree of bacterial infection. Before using antibiotics, patients should take the initiative to explain their allergy history to the doctor. 2, drugs containing a small amount of ephedrine. This medicine is able to narrow the nasal cavity when it enters the nasal cavity. Patients with acute sinusitis who suffer from headaches can change their posture to improve the ventilation conditions in the sinuses and relieve the headache. Patients with chronic sinusitis can use vasoconstrictors to improve the state of the mucous membrane in the nose and promote drainage. 3. Antihistamines and drugs that promote mucus drainage. The former can relieve the discomfort caused by sneezing and other diseases. The latter has the effect of shortening the cure time. Patients with chronic sinusitis need long-term treatment to be cured. During this period, some patients do not trust hospitals and treat with prescriptions, causing their condition to become worse.
