* For patients with  purulent [[cellulitis]], cultures are recommended and empirical therapy for Community Associated-MRSA (CA-MRSA) should be started.

* For patients with non-purulent [[cellulitis]], empirical therapy for [[β-hemolytic streptococci]] should be started.

* The duration of the therapy should be individualized for the clinical response of each patient; 5-10 days is usually recommended.
* The treatment of [[cellulitis]] in neonates usually requires hospitalization and parenteral therapy.  Oral therapy is given for completion of the treatment when the pathogen is unknown.
* Optimal dose should be based on determination of serum concentrations.
* Patients with renal insufficiency may require dose adjustment in case of [[cephalosporins]].
* [[Clindamycin]] is an alternate therapy for patients at risk of severe hypersensitivity reaction to [[penicillins]] and [[cephalosporins]].
* [[Doxycycline]] is '''NOT''' recommended for children <8 years of age.
* Studies have shown an increase in treatment failure with [[TMP-SMX]] compared to other agents for [[cellulitis]] in children, reflecting [[TMP-SMX]] less action against [[Group A streptococcus]].<ref name="pmid19470525">{{cite journal| author=Elliott DJ, Zaoutis TE, Troxel AB, Loh A, Keren R| title=Empiric antimicrobial therapy for pediatric skin and soft-tissue infections in the era of methicillin-resistant Staphylococcus aureus. | journal=Pediatrics | year= 2009 | volume= 123 | issue= 6 | pages= e959-66 | pmid=19470525 | doi=10.1542/peds.2008-2428 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=19470525  }} </ref>
