What Drugs Interact With Zosyn?

Zosyn may interact with probenecid, antibiotics, blood thinners, or any other medication used to prevent blood clots. Tell your doctor all medications you use.

What Drugs Interact With Augmentin?

Augmentin may interact with probenecid.

Augmentin may also interact with allopurinol, blood thinners, or other antibiotics.

How Should Zosyn Be Taken?

The usual total daily dose of Zosyn for adults is 3.375 g every six hours totaling 13.5 g (12.0 g piperacillin/1.5 g tazobactam).

How Should Augmentin Be Taken?

For Adults:

  • The usual adult dose is one 500-mg tablet of Augmentin every 12 hours or one 250-mg tablet of Augmentin every 8 hours. For more severe infections and infections of the respiratory tract, the dose should be one 875-mg tablet of Augmentin every 12 hours or one 500-mg tablet of Augmentin every 8 hours. Adults who have difficulty swallowing may be given the 125 mg/5 mL or 250 mg/5 mL suspension in place of the 500-mg tablet. The 200 mg/5 mL suspension or the 400 mg/5 mL suspension may be used in place of the 875-mg tablet.
  • Two 250-mg tablets of Augmentin should not be substituted for one 500-mg tablet of Augmentin. Since both the 250-mg and 500-mg tablets of Augmentin contain the same amount of clavulanic acid (125 mg, as the potassium salt), two 250-mg tablets are not equivalent to one 500-mg tablet of Augmentin.
  • The 250-mg tablet of Augmentin and the 250-mg chewable tablet should not be substituted for each other, as they are not interchangeable. The 250-mg tablet of Augmentin and the 250-mg chewable tablet do not contain the same amount of clavulanic acid (as the potassium salt). The 250-mg tablet of Augmentin contains 125 mg of clavulanic acid, whereas the 250-mg chewable tablet contains 62.5 mg of clavulanic acid.

For Pediatric Patients

Based on the amoxicillin component, Augmentin should be dosed as follows:

Neonates And Infants Aged under 12 Weeks (under 3 Months)

  • The recommended dose of Augmentin is 30 mg/kg/day divided every 12 hours, based on the amoxicillin component. Experience with the 200 mg/5 mL formulation in this age group is limited, and thus, use of the 125 mg/5 mL oral suspension is recommended.

Patients Aged 12 Weeks (3 Months) And Older

  • The every 12 hour regimen is recommended as it is associated with significantly less diarrhea. However, the every 12 hour suspension (200 mg/5 mL and 400 mg/5 mL) and chewable tablets (200 mg and 400 mg) contain aspartame and should not be used by phenylketonurics.
