Cefalexin is not effective against infections caused by methicillin-resistant Staphylococcus aureus (MRSA), most Enterococcus, or Pseudomonas. [4] Like other antibiotics, cefalexin cannot treat viral infections, such as the flu, common cold or acute bronchitis. [4] Cefalexin can be used in those who have mild or moderate allergies to penicillin ...
MRSA can infect the central nervous system and form brain abscess, subdural empyema, and spinal epidural abscess. Excision and drainage can be done along with antibiotic treatment. Septic thrombosis of cavernous or dural venous sinus can sometimes be a complication. [4]
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
Alternative antibiotics effective against community-acquired MRSA often include clindamycin, doxycycline, minocycline, and trimethoprim-sulfamethoxazole. [1] The American College of Emergency Physicians advises that typical cases of abscess from MRSA get no benefit from having antibiotic treatment in addition to the standard treatment. [4]
Dicloxacillin is a narrow-spectrum β-lactam antibiotic of the penicillin class. [1] It is used to treat infections caused by susceptible (non-resistant) Gram-positive bacteria . [ 1 ] It is active against beta-lactamase -producing organisms such as Staphylococcus aureus , which would otherwise be resistant to most penicillins .
Cefadroxil is a first-generation cephalosporin antibacterial drug that is the para-hydroxy derivative of cephalexin, and is used similarly in the treatment of mild to moderate susceptible infections such as the bacterium Streptococcus pyogenes, causing the disease popularly called strep throat or streptococcal tonsillitis, urinary tract infection, reproductive tract infection, and skin infections.
Ceftaroline fosamil / s ɛ f ˈ t ær oʊ l iː n /, brand name Teflaro in the US and Zinforo in Europe, [1] [2] is a cephalosporin antibiotic with anti-MRSA activity. [3] Ceftaroline fosamil is a prodrug of ceftaroline. It is active against methicillin-resistant Staphylococcus aureus (MRSA) and other Gram-positive bacteria.
The use of topical antibiotics to treat surgical wounds does not reduce infection rates in comparison with non-antibiotic ointment or no ointment at all. [18] The use of doxycycline in acne vulgaris has been associated with increased risk of Crohn's disease. [19] The use of minocycline in acne vulgaris has been associated with skin and gut ...
