Clarithromycin tablets, rhinitis is available for both acute and chronic rhinitis. The antibiotic of choice for acute sinusitis is macrolides, second-generation cephalosporins, or amoxicillin clavulanic acid potassium are available. Especially for chronic sinusitis, small doses of macrolide antibiotics are clinically recommended for long-term treatment. The macrolides required are above the fourteen dollar ring, commonly used are roxithromycin and clarithromycin. Clarithromycin belongs to the macrolide class. Small doses, such as roxithromycin, are 2 times/day, 1 capsule/time. Smaller doses are those that are given 1 time/day, 1 capsule/dose. Long-term use is usually lasting up to 3 months. Macrolides, such as clarithromycin, are useful for chronic sinusitis not only because they are antibiotics that can reduce inflammation, but mainly because they play a role in regulating immunity and reducing inflammation in the nasal mucosa. This has been clinically approved and is perfectly fine to use, but you need to strictly follow medical advice and not use it privately.
