What are 3 top antibiotics?
In this article we will describe what are the 3 top antibiotics.
There are not really a ‘top 3’, as different infections need different antibiotics. But these 3 groups are commonly used.
1. Cephalosporins
E.g. Cephalexin (also cefuroxime, ceftriaxone, ceftazidime)
Uses: broad-spectrum antibiotics, used to treat more serious infections including sepsis/septicaemia and meningitis
Other uses: different ones are used for pneumonia, and biliary and urinary tract infections (UTIs)
2. Macrolides
E.g. Erythromycin (and clarithromycin, azithromycin)
Uses: chest infections and pneumonia, especially if you are allergic to penicillins
Other uses: skin conditions, such as acne and rosacea, dental abscesses, and some sexually transmitted diseases (STDs)
3. Penicillins
E.g. Amoxicillin (and benzylpenicillin, piperacillin, ticarcillin, Co-amoxiclav, flucloxacillin)
Uses: widely used to treat chest, ear, skin, and urinary tract infections (UTIs)
Other uses: pneumonia, meningitis, and Strep A throat
Note 1. Amoxicillin/clavulanic acid (‘Co-amoxiclav’) is a commonly used form of penicillin
Note 2. Flucloxacillin is used for skin and wound infections, bone infections (osteomyelitis), and ear infections in children.
