Unasyn (ampicillin sodium/sulbactam sodium) is a combination antibiotic indicated for the treatment of infections due to susceptible strains of microorganisms.

Amoxil (amoxicillin) is a penicillin-type antibiotic used to treat infections caused by bacteria that are B-lactamase negative (B-lactamase positive bacteria are usually resistant to Amoxil (amoxicillin)); these infections usually occur in the skin, lungs, urinary tract and eye, ears, nose, and throat. Amoxil (amoxicillin) is available as a generic drug termed amoxicillin. Amoxil (amoxicillin) may be combined with other drugs (for example, clavulanic acid [Augmentin]), to make the antibiotic more effective.

Unasyn may interact with allopurinol, probenecid, or other antibiotics.

Amoxil (amoxicillin) may interact with probenecid, blood thinners, other antibiotics, or sulfa drugs. Tell your doctor all medications and supplements you use. Treatment in pregnant women and women who are breastfeeding should be done with caution.

Unasyn is administered orally in the form of tablets.

Amoxil (amoxicillin) is available in many preparations (capsules, tablets, chewable tablets, powder for oral suspension and pediatric oral suspension).
