What medications are used after surgery? The most commonly used medications are hormones, mucus-thinning medications, antibiotics, and so on. Each drug has its own special role. Hormones can prevent nasal edema and control vesicle generation 1. nasal hormones: we should not talk about hormones, in fact, nasal hormones only work locally and have very little effect on the whole body. It should be said that nasal hormones are very safe and essential drugs to prevent recurrence after surgery. The function of nasal hormones is to prevent edema and control the formation of polypoid vesicles, and the commonly used drugs are Reynocort, Nesuna, and Cochlear, etc. The duration and dosage of nasal hormones should be set by the doctor according to the patient’s condition, and there are no specific limits. If the doctor does not recommend stopping the medication, the patient should never stop using it without permission, otherwise the condition is likely to return, and some patients may even need to use nasal hormones for life to control the development of the disease. 2. Oral hormones: For some patients with refractory sinusitis, it is also recommended to take oral hormones, such as prednisone, for a period of time during the postoperative recovery period. Surgery is invasive and requires appropriate antibiotics.3. Antibiotics: Because surgery is, after all, invasive, we generally recommend that patients take oral antibiotics for 1 to 2 weeks. Some scholars also propose that long-term oral macrolide antibiotics can be taken, such as clarithromycin 1 capsule/day for three months. The exact regimen will depend on the patient’s condition. Dilute mucus-like drugs to prevent mucus from blocking the nasal cavity 4. Dilute mucus-like drugs: These drugs can dilute the secretions in the sinus cavity to prevent mucus from being too sticky and blocking the sinus opening. The human sinuses themselves have the ability to self-clean – the nasal cilia constantly send mucus adsorbed with dust and harmful bacteria from the sinuses to the nasal cavity through regular oscillation, thus discharging the body, and mucus thinning helps the cilia oscillation and mucus discharge. Mucus thinning drugs need to be used for about 1 month after surgery.5. Other: Chinese medicines, such as chamomile capsules, can be used; patients with asthma can use leukotriene receptor antagonists, such as shunerin, etc. Tips: Local glucocorticosteroids: they are usually used continuously after surgery, and there is no fixed period of use, and they can be stopped only according to medical advice. Some patients with allergic rhinitis often require lifelong use. Oral hormones: Patients with refractory sinusitis may need to take them for a period of time after surgery. Antibiotics: generally used for less than two weeks postoperatively (longer depending on the nature of the secretions). Mucus-thinning drugs: more than one month.
