Other Comments

Administration advice:
-This drug may be taken without regard to food.
-Oral suspension: Shake well prior to administration.

Storage requirements:
-Oral suspension: Keep tightly closed; store reconstituted solution for up to 14 days, then discard unused portion after 14 days.

General:
-There was a lack of bioequivalence between oral suspension and tablet formulations in adult patients. Providers should consider bioequivalence when selecting formulations and should avoid using tablet formulations when treating otitis media in children.
-Local epidemiological and susceptibility patterns should be used to guide treatment selection in the absence of patient-specific culture and susceptibility information.
-Spectrum of Activity: This drug has shown activity in vitro and in clinical infections including Branhamella catarrhalis (beta-lactamase positive/negative), Enterobacter species, Escherichia coli, Haemophilus influenzae (beta-lactamase positive/negative), Klebsiella species, Proteus mirabilis, Streptococcus pneumoniae, Streptococcus pyogenes, and in the presence of beta-lactamase enzymes.
-Limitations of use: Many of the following strains have been found to be resistant to this drug: Bacteroides fragilis, Clostridia, enterococci (Streptococcus faecalis, group D streptococci), Listeria monocytogenes, Pseudomonas, staphylococci (e.g., coagulase-positive/-negative strains, methicillin-resistant strains).

Patient advice:
-Inform patients that this drug may cause confusion, convulsion, impairment in consciousness, movement disorders, and/or other side effects related to encephalitis, and they should avoid driving or operating machinery if these side effects occur.
-Patients should be directed to take the full course of treatment, even if they feel better.
-Patients should be instructed to report signs/symptoms of Clostridium difficile (e.g., watery/bloody stools, stomach cramps, fever), for up to 2 months after stopping treatment.
