Administer by IV infusion.1
Not for administration via inhalation.1 (See Pneumonitis under Cautions.)
For solution and drug compatibility information, see Compatibility under Stability.
Use strict aseptic technique since drug product contains no preservative.1
Reconstitute vial containing 500 mg of doripenem with 10 mL of sterile water for injection or 0.9% sodium chloride injection; shake gently to provide a suspension containing 50 mg/mL.1
Reconstituted suspension is not for direct injection; must be further diluted in ≤1 hour following reconstitution.1 (See Storage under Stability.)
For a 500-mg dose, withdraw contents of the reconstituted vial with a 21-gauge needle and add it to an infusion bag containing 100 mL of 0.9% sodium chloride injection or 5% dextrose for injection to provide a solution containing 500 mg (4.5 mg/mL); gently shake until clear.1
For a 250-mg dose, withdraw contents of the reconstituted vial with a 21-gauge needle and add it to an infusion bag containing 100 mL of 0.9% sodium chloride injection or 5% dextrose for injection; gently shake until clear.1 Remove and discard 55 mL of the solution from the bag to provide a solution containing 250 mg (4.5 mg/mL).1

Clcr (mL/minute) | Daily Dosage |
---|---|
30–50 | 250 mg every 8 hours |
11–29 | 250 mg every 12 hours |
Insufficient data to recommend dosage adjustments in patients undergoing hemodialysis.1
No dosage adjustments except those related to renal impairment.1 (See Renal Impairment under Dosage and Administration.)
Known hypersensitivity to doripenem or other carbapenems.1
History of anaphylactic reaction to β-lactams.1
Treatment with anti-infectives may permit overgrowth of Clostridium difficile.1 19 20 21 22 23 C. difficile-associated diarrhea and colitis (CDAD; also known as antibiotic-associated diarrhea and colitis or pseudomembranous colitis) has been reported with nearly all anti-infectives and may range in severity from mild diarrhea to fatal colitis.1
Consider CDAD if diarrhea develops during or after therapy and manage accordingly.1 19 20 21 22 23 Obtain a careful medical history since CDAD may occur as late as ≥2 months after anti-infective therapy is discontinued.1
If CDAD is suspected or confirmed, the anti-infective may need to be discontinued.1 Manage moderate to severe cases with fluid, electrolyte, and protein supplementation; appropriate anti-infective therapy (e.g., oral metronidazole or vancomycin); and surgical evaluation when clinically indicated.1 19 20 21 22 23
Use only for treatment or prevention of infections proven or strongly suspected to be caused by susceptible bacteria.1
Use results of culture and in vitro susceptibility testing.1 If such data are unavailable, consider local epidemiology and susceptibility patterns when selecting anti-infectives for empiric therapy.1
Pneumonitis reported following administration by inhalation†;1 not for inhalation administration.1
Doripenem reduces valproic acid serum concentrations to subtherapeutic concentrations; possible increased risk of seizures.a Monitor serum valproic acid concentrations and consider alternative therapies.a (See Specific Drugs under Interactions.)
Serious and occasionally fatal hypersensitivity reactions (e.g., anaphylaxis) and serious skin reactions (e.g., Stevens-Johnson syndrome, toxic epidermal necrolysis) reported.1
If hypersensitivity occurs, discontinue doripenem and institute appropriate therapy as indicated (e.g., epinephrine, corticosteroids, IV fluids, IV antihistamines, pressor amines, oxygen and maintenance of an adequate airway).1
Cross-allergenicity occurs among β-lactam antibiotics, including penicillins, cephalosporins, and other β-lactams.1
Prior to initiation of therapy, make careful inquiry concerning previous hypersensitivity reactions to doripenem, cephalosporins, penicillins, or other drugs.1
Seizures and other CNS effects (e.g., confusional states, myoclonic activity) reported with carbapenems (e.g., ertapenem, imipenem, meropenem), especially in those with underlying CNS disorders (e.g., brain lesions, history of seizures) and/or compromised renal function.8 10 24 25 26
Rarely, seizures reported in patients receiving doripenem;1 causality not established.1
Category B.1
Not known if doripenem is distributed into milk.1 Use with caution.1
Safety and efficacy not established in patients <18 years of age.1
No substantial differences in safety relative to younger adults, but increased sensitivity cannot be ruled out.1
Substantially eliminated by kidneys; risk of adverse reactions may be greater in geriatric patients with impaired renal function or prerenal azotemia.1 Select dosage with caution and assess renal function periodically since geriatric patients are more likely to have renal impairment.1
Pharmacokinetics not established but impact of hepatic impairment should be minimal.1
Increased AUC.1 Dosage adjustments and monitoring of renal function recommended in patients with moderate or severe renal impairment (Clcr ≤50 mL/minute).1 (See Special Populations under Dosage and Administration.)
Risk of adverse reactions may be greater in patients with impaired renal function.1
Headache, nausea, diarrhea, rash, phlebitis.1

Not expected to induce UGT 1A1;1 pharmacokinetic interactions unlikely with drugs metabolized by this enzyme.1

Synthetic carbapenem β-lactam antibiotic; structurally and pharmacologically related to ertapenem, imipenem, and meropenem.1 3
Usually bactericidal in action.1
Like other β-lactam antibiotics, antibacterial activity results from inhibition of bacterial cell wall synthesis.1 3 10
Spectrum of activity includes many aerobic and anaerobic gram-positive and gram-negative bacteria.1 3 4 5 10
Reported as more active than some other carbapenems against Enterobacteriaceae and Ps. aeruginosa.2 3 4 9 10 12 18
Gram-positive aerobes: Active in vitro and in clinical infections against Streptococcus intermedius1 and S. constellatus.1 Also active in vitro against Staphylococcus aureus (including oxacillin-susceptible [methicillin-susceptible] strains),1 4 S. epidermidis,4 S. agalactiae (group B streptococci),1 4 and S. pyogenes (group A β-hemolytic streptococci).1 Oxacillin-resistant (methicillin-resistant) staphylococci are resistant.1
Gram-negative aerobes: Active in vitro and in clinical infections against E. coli,1 4 Klebsiella pneumoniae,1 4 Proteus mirabilis,1 4 Ps. aeruginosa,1 4 and Acinetobacter baumannii.1 Also active in vitro against Citrobacter freundii,1 Enterobacter cloacae,1 4 E. aerogenes,1 4 K. oxytoca,1 4 Morganella morganii,1 and Serratia marcescens1 and some strains of Burkholderia cepacia.17 18
Anaerobes: Active in vitro and in clinical infections against Bacteroides fragilis,1 4 5 B. caccae,1 4 B. thetaiotaomicron,1 4 5 B. uniformis,1 4 B. vulgatus,1 4 and Peptostreptococcus micros.1 4 5
Cross-resistance may occur with other carbapenems; however, some isolates (e.g., some strains of Ps. aeruginosa) resistant to other carbapenems may be susceptible to doripenem.1 4
Advise patients that antibacterials (including doripenem) should only be used to treat bacterial infections and not used to treat viral infections (e.g., the common cold).1
Importance of completing full course of therapy, even if feeling better after a few days.1
Advise patients that skipping doses or not completing the full course of therapy may decrease effectiveness and increase the likelihood that bacteria will develop resistance and will not be treatable with doripenem or other antibacterials in the future.1
Importance of informing clinicians of any previous hypersensitivity reactions to doripenem, other carbapenems, β-lactams, or other allergens.1
Importance of discontinuing therapy and informing clinician if an allergic or hypersensitivity reaction occurs.1
Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, and any concomitant illnesses.1
Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1
Importance of informing patients of other important precautionary information.1 (See Cautions.)
Excipients in commercially available drug preparations may have clinically important effects in some individuals; consult specific product labeling for details.
