4.3 Contraindications
- Hypersensitivity to the active substances or to any of the excipients listed in section 6.1;
- Hypersensitivity to any cephalosporin antibacterial agent;
- Severe hypersensitivity (e.g., anaphylactic reaction, severe skin reaction) to any other type of
beta-lactam antibacterial agent (e.g., penicillins or carbapenems).
4.4 Special warnings and precautions for use
Hypersensitivity reactions
Serious and occasionally fatal hypersensitivity (anaphylactic) reactions are possible (see sections 4.3
and 4.8). If a severe allergic reaction occurs during treatment with ceftolozane/tazobactam, the
medicinal product should be discontinued and appropriate measures taken.
Patients who have a history of hypersensitivity to cephalosporins, penicillins or other beta-lactam
antibacterial agents may also be hypersensitive to ceftolozane/tazobactam.
Ceftolozane/tazobactam is contraindicated in patients with a history of hypersensitivity to ceftolozane,
tazobactam, or cephalosporins (see section 4.3).
Ceftolozane/tazobactam is also contraindicated in patients with severe hypersensitivity (e.g.
anaphylactic reaction, severe skin reaction) to any other type of beta-lactam antibacterial agent (e.g.
penicillins or carbapenems) (see section 4.3).
Ceftolozane/tazobactam should be used with caution in patients with a history of any other type of
hypersensitivity reaction to penicillins or other beta-lactam antibacterial agents.
Effect on renal function
A decline in renal function has been seen in patients receiving ceftolozane/tazobactam.
Impaired renal function
The ceftolozane/tazobactam dose should be adjusted based on renal function (see section 4.2, Table 2).
In clinical trials the efficacy of ceftolozane/tazobactam was lower in patients with moderate renal
impairment compared with those with normal or mildly impaired renal function at baseline. Patients
with renal impairment at baseline should be monitored frequently for any changes in renal function
during treatment and the dose of ceftolozane/tazobactam should be adjusted as necessary.
Limitations of the clinical data
Patients who were immunocompromised and patients with severe neutropenia were excluded from
clinical trials.
In a trial in patients with complicated intra-abdominal infections, the most common diagnosis was
appendiceal perforation or peri-appendiceal abscess (420/970 [43.3%] patients), of which 137/420
(32.6%) had diffuse peritonitis at baseline. Approximately 82% of all patients in the trial had
APACHE II (Acute Physiology and Chronic Health Evaluation II) scores of < 10 and 2.3% had
bacteraemia at baseline. In the clinically evaluable (CE) patients, the clinical cure rates for
ceftolozane/tazobactam were 95.9% in 293 patients aged less than 65 years and 87.8% in 82 patients
aged 65 years or more.
Clinical efficacy data in patients with complicated lower urinary tract infection are limited. In a
randomised active-controlled trial 18.2% (126/693) of microbiologically evaluable (ME) patients had
5
complicated lower urinary tract infection (cLUTI), including 60/126 patients who were treated with
ceftolozane/tazobactam. One of these 60 patients had bacteraemia at baseline.
Clostridium difficile-associated diarrhoea
Antibacterial-associated colitis and pseudomembranous colitis have been reported with
ceftolozane/tazobactam (see section 4.8). These types of infection may range in severity from mild to
life threatening. Therefore, it is important to consider this diagnosis in patients who present with
diarrhoea during or subsequent to the administration of ceftolozane/tazobactam. In such
circumstances, the discontinuation of therapy with ceftolozane/tazobactam and the use of supportive
measures together with the administration of specific treatment for Clostridium difficile should be
considered.
Non-susceptible micro-organisms
The use of ceftolozane/tazobactam may promote the overgrowth of non-susceptible micro-organisms.
If super infection occurs during or following treatment, appropriate measures should be taken.
Ceftolozane/tazobactam is not active against bacteria that produce beta-lactamase enzymes which are
not inhibited by tazobactam. See section 5.1.
Direct antiglobulin test (Coombs test) seroconversion and potential risk of haemolytic anaemia
The development of a positive direct antiglobulin test (DAGT) may occur during treatment with
ceftolozane/tazobactam. The incidence of DAGT seroconversion in patients receiving
ceftolozane/tazobactam was 0.2% in the clinical trials. In clinical studies, there was no evidence of
haemolysis in patients who developed a positive DAGT on treatment.
Sodium content
Ceftolozane/tazobactam contains 10.0 mmol (230 mg) of sodium per vial. The reconstituted vial with
10 mL of 0.9% sodium chloride (normal saline) for injection contains 11.5 mmol (265 mg) of sodium.
This should be taken into consideration while treating patients on controlled-sodium diet.
4.5 Interaction with other medicinal products and other forms of interaction
No significant medicinal product interactions are anticipated between ceftolozane/tazobactam and
substrates, inhibitors, and inducers of cytochrome P450 enzymes (CYPs) based on in vitro and in vivo
studies.
In vitro studies demonstrated that ceftolozane, tazobactam and the M1 metabolite of tazobactam did
not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, or CYP3A4 and did not
induce CYP1A2, CYP2B6, or CYP3A4 at therapeutic plasma concentrations.
Ceftolozane and tazobactam were not substrates for P-gp or BCRP, and tazobactam was not a
substrate for OCT2, in vitro at therapeutic plasma concentrations. In vitro data indicate that
ceftolozane did not inhibit P-gp, BCRP, OATP1B1, OATP1B3, OCT1, OCT2, MRP, BSEP, OAT1,
OAT3, MATE1, or MATE2-K in vitro at therapeutic plasma concentrations. In vitro data indicate that
neither tazobactam nor the tazobactam metabolite M1 inhibit P-gp, BCRP, OATP1B1, OATP1B3,
OCT1, OCT2, or BSEP transporters at therapeutic plasma concentrations.
Tazobactam is a substrate for OAT1 and OAT3. In vitro, tazobactam inhibited human OAT1 and
OAT3 transporters with IC50 values of 118 and 147 mcg/mL, respectively. Co-administration of
ceftolozane/tazobactam with OAT1 and OAT3 substrate furosemide in a clinical study did not
significantly increase furosemide plasma exposures (geometric mean ratios of 0.83 and 0.87 for Cmax
and AUC, respectively). However, active substances that inhibit OAT1 or OAT3 (e.g., probenecid)
may increase tazobactam plasma concentrations.

4.6 Fertility, pregnancy and lactation
Pregnancy
There are no data on the use of ceftolozane/tazobactam in pregnant women. Tazobactam crosses the
placenta. It is not known if ceftolozane crosses the placenta.
Animal studies with tazobactam have shown reproductive toxicity (see section 5.3) without evidence
of teratogenic effects. Studies with ceftolozane in mice and rats have not shown evidence of
reproductive toxicity or teratogenicity. Ceftolozane administered to rats during pregnancy and
lactation was associated with a decrease in auditory startle response in postnatal day (PND) 60 male
pups (see section 5.3).
Zerbaxa should only be used during pregnancy if the expected benefit outweighs the possible risks to
the pregnant woman and foetus.
Breast-feeding
It is unknown whether ceftolozane and tazobactam are excreted in human milk. A risk to
newborns/infants cannot be excluded. A decision must be made whether to discontinue breast-feeding
or to discontinue/abstain from Zerbaxa therapy taking into account the benefit of breast-feeding for the
child and the benefit of therapy for the woman.
Fertility
The effects of ceftolozane and tazobactam on fertility in humans have not been studied. Fertility
studies in rats showed no effect on fertility and mating after intraperitoneal administration of
tazobactam or intravenous administration of ceftolozane (see section 5.3).
4.7 Effects on ability to drive and use machines
Zerbaxa may have a minor influence on the ability to drive and use machines. Dizziness may occur
following administration of Zerbaxa (see section 4.8).
4.8 Undesirable effects
Summary of the safety profile
Zerbaxa was evaluated in Phase 3 comparator-controlled clinical trials of complicated intra-abdominal
infections and complicated urinary tract infections (including pyelonephritis), which included a total
of 1,015 patients, treated with Zerbaxa (1 g / 0.5 g intravenously every 8 hours, adjusted to match
renal function where appropriate) for up to 14 days.
The most common adverse reactions (≥ 3% in pooled Phase 3 trials) occurring in patients receiving
Zerbaxa were nausea, headache, constipation, diarrhoea, and pyrexia and were generally mild or
moderate in severity.
Tabulated list of adverse reactions

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It
allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare
professionals are asked to report any suspected adverse reactions via the national reporting system
listed in Appendix V.
4.9 Overdose
There is no experience with overdose of Zerbaxa. The highest single dose of Zerbaxa used in clinical
trials was 3 g / 1.5 g of ceftolozane/tazobactam administered to healthy volunteers.
In the event of overdose, Zerbaxa should be discontinued and general supportive treatment given.
Zerbaxa can be removed by haemodialysis. Approximately 66% of ceftolozane, 56% of tazobactam,
and 51% of the M1 metabolite of tazobactam were removed by dialysis.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antibacterials for systemic use, other cephalosporins and penems, ATC
code: J01DI54.
8
Mechanism of action
Ceftolozane belongs to the cephalosporin class of antimicrobials. Ceftolozane exerts bactericidal
activity through binding to important penicillin-binding proteins (PBPs), resulting in inhibition of
bacterial cell-wall synthesis and subsequent cell death.
Tazobactam is a beta-lactam structurally related to penicillins. It is an inhibitor of many Molecular
Class A beta-lactamases, including CTX-M, SHV, and TEM enzymes. See below.
Mechanisms of resistance
Mechanisms of bacterial resistance to ceftolozane/tazobactam include:
i. Production of beta-lactamases that can hydrolyse ceftolozane and which are not inhibited
by tazobactam (see below)
ii. Modification of PBPs
Tazobactam does not inhibit all Class A enzymes.
In addition tazobactam does not inhibit the following types of beta-lactamase:
i. AmpC enzymes (produced by Enterobacteriaceae)
ii. Serine-based carbapenemases (e.g., Klebsiella pneumoniae carbapenemases [KPCs])
iii. Metallo-beta-lactamases (e.g., New Delhi metallo-beta-lactamase [NDM])
iv. Ambler Class D beta-lactamases (OXA-carbapenemases)
Pharmacokinetic/pharmacodynamic relationships
For ceftolozane the time that the plasma concentration exceeds the minimum inhibitory concentration
of ceftolozane for the infecting organism has been shown to be the best predictor of efficacy in animal
models of infection.
For tazobactam the PD index associated with efficacy was determined to be the percentage of the dose
interval during which the plasma concentration of tazobactam exceeds a threshold value
(%T>threshold). The threshold concentration required is dependent on the organism and the amount
and type of β-lactamase produced.
Susceptibility testing breakpoints
Minimum inhibitory concentration breakpoints established by the European Committee on
Antimicrobial Susceptibility Testing (EUCAST) are as follows:
Minimum Inhibitory
Concentrations (mg/L)
Pathogen Susceptible Resistant
Enterobacteriaceae ≤ 1 > 1
P. aeruginosa ≤ 4 > 4
Clinical efficacy against specific pathogens
Efficacy has been demonstrated in clinical studies against the pathogens listed under each indication
that were susceptible to Zerbaxa in vitro:
Complicated intra-abdominal infections
Gram-negative bacteria
Enterobacter cloacae
Escherichia coli
Klebsiella oxytoca
9
Klebsiella pneumoniae
Proteus mirabilis
Pseudomonas aeruginosa
Gram-positive bacteria
Streptococcus anginosus
Streptococcus constellatus
Streptococcus salivarius
Complicated Urinary Tract Infections, including pyelonephritis
Gram-negative bacteria
Escherichia coli
Klebsiella pneumoniae
Proteus mirabilis
Clinical efficacy has not been established against the following pathogens although in vitro studies
suggest that they would be susceptible to Zerbaxa in the absence of acquired mechanisms of
resistance:
Citrobacter freundii
Citrobacter koseri
Enterobacter aerogenes
Morganella morganii
Proteus vulgaris
Serratia liquefacians
Serratia marcescens
In vitro data indicate that the following species are not susceptible to ceftolozane/tazobactam:
Staphylococcus aureus
Enterococcus faecalis
Enterococcus faecium
Paediatric population
The European Medicines Agency has deferred the obligation to submit the results of studies with
Zerbaxa in one or more subsets of the paediatric population in complicated intra-abdominal infection
and complicated urinary tract infection (see section 4.2 for information on paediatric use).
5.2 Pharmacokinetic properties
The Cmax and AUC of ceftolozane/tazobactam increase approximately in proportion to dose within
ceftolozane single-dose range of 250 mg to 3 g and tazobactam single-dose range of 500 mg to 1.5 g.
No appreciable accumulation of ceftolozane/tazobactam is observed following multiple 1-hour IV
infusions of 1 g / 0.5 g ceftolozane/tazobactam administered every 8 hours for up to 10 days in healthy
adults with normal renal function. The elimination half-life (t½) of ceftolozane is independent of dose.
Distribution
The binding of ceftolozane and tazobactam to human plasma proteins is low (approximately 16% to
21% and 30%, respectively).The mean (coefficient of variation CV%) steady-state volume of
distribution of ceftolozane/tazobactam in healthy adult males (n = 51) following a single 1 g / 0.5 g IV
dose was 13.5 L (21%) and 18.2 L (25%) for ceftolozane and tazobactam, respectively, similar to
extracellular fluid volume.
10
Biotransformation
Ceftolozane is eliminated in the urine as unchanged parent substance and thus does not appear to be
metabolised to any appreciable extent. The beta-lactam ring of tazobactam is hydrolyzed to form the
pharmacologically inactive, tazobactam metabolite M1.
Elimination
Ceftolozane, tazobactam and the tazobactam metabolite M1 are eliminated by the kidneys. Following
administration of a single 1 g / 0.5 g IV dose of ceftolozane/tazobactam to healthy male adults greater
than 95% of ceftolozane was excreted in the urine as unchanged parent substance. More than 80% of
tazobactam was excreted as the parent compound with the remaining amount excreted as the
tazobactam M1 metabolite. After a single dose of ceftolozane/tazobactam, renal clearance of
ceftolozane (3.41 - 6.69 L/h) was similar to plasma clearance (4.10 - 6.73 L/h) and similar to the
glomerular filtration rate for the unbound fraction, suggesting that ceftolozane is eliminated by the
kidney via glomerular filtration.
The mean terminal elimination half-life of ceftolozane and tazobactam in healthy adults with normal
renal function is approximately 3 hours and 1 hour, respectively.
Linearity/non-linearity
The Cmax and AUC of ceftolozane/tazobactam increase in proportion to dose. Plasma levels of
ceftolozane/tazobactam do not increase appreciably following multiple IV infusions of up to
2.0 g / 1.0 g administered every 8 hours for up to 10 days in healthy adults with normal renal function.
The elimination half-life (t½) of ceftolozane is independent of dose.
Special populations
Renal impairment
Ceftolozane/tazobactam and the tazobactam metabolite M1 are eliminated by the kidneys.
The ceftolozane dose normalized geometric mean AUC increased up to 1.26-fold, 2.5-fold, and 5-fold
in subjects with mild, moderate, and severe renal impairment, respectively, compared to healthy
subjects with normal renal function. The respective tazobactam dose normalized geometric mean AUC
increased approximately up to 1.3-fold, 2-fold, and 4-fold. To maintain similar systemic exposures to
those with normal renal function, dosage adjustment is required (see section 4.2).
In subjects with end stage renal disease on haemodialysis, approximately two-thirds of the
administered ceftolozane/tazobactam dose is removed by haemodialysis. The recommended dose in
subjects with end stage renal disease on haemodialysis is a single loading dose of 500 mg / 250 mg
ceftolozane/tazobactam followed by a 100 mg / 50 mg maintenance dose of ceftolozane/tazobactam
administered every 8 hours for the remainder of the treatment period. With haemodialysis, the dose
should be administered immediately following completion of dialysis (see section 4.2).
Hepatic impairment
As ceftolozane/tazobactam does not undergo hepatic metabolism, the systemic clearance of
ceftolozane/tazobactam is not expected to be affected by hepatic impairment. No dose adjustment is
recommended for ceftolozane/tazobactam in subjects with hepatic impairment (see section 4.2).
Elderly
In a population pharmacokinetic analysis of ceftolozane/tazobactam, no clinically relevant trend in
exposure was observed with regard to age. No dose adjustment of ceftolozane/tazobactam based on
age alone is recommended.
11
Paediatric patients
Safety and efficacy in paediatric patients have not been established.
Gender
In a population pharmacokinetic analysis of ceftolozane/tazobactam, no clinically relevant differences
in AUC were observed for ceftolozane (116 males compared to 70 females) and tazobactam (80 males
compared to 50 females). No dose adjustment is recommended based on gender.
Ethnicity
In a population pharmacokinetic analysis of ceftolozane/tazobactam, no clinically relevant differences
in ceftolozane/tazobactam AUC were observed in Caucasians (n = 156) compared to all other
ethnicities combined (n = 30). No dose adjustment is recommended based on race.
5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of safety
pharmacology, repeated dose toxicity or genotoxicity. Carcinogenicity studies with
ceftolozane/tazobactam have not been conducted.
Effects in non-clinical studies were observed only at exposures considered sufficiently in excess of the
maximum human exposure indicating little relevance to clinical use.
Adverse reactions not observed in clinical studies, but seen in animals at exposure levels similar to
clinical exposure levels and with possible relevance to clinical use were as follows: ceftolozane
administered to rats during pregnancy and lactation was associated with a decrease in auditory startle
response in postnatal day (PND) 60 male pups at maternal doses of 300 and 1,000 mg/kg/day. A dose
of 300 mg/kg/day to rats was associated with a ceftolozane plasma exposure (AUC) value
approximately equivalent to the ceftolozane plasma AUC value at the human therapeutic dose.
Peri/postnatal development was impaired (reduced pup weights, increase in stillbirths, increase in pup
mortality) concurrent with maternal toxicity after intraperitoneal administration of tazobactam in the
rat.

6. Contents of the pack and other information
1. What Zerbaxa is and what it is used for
Zerbaxa is a medicine used to treat a range of bacterial infections. It contains two active substances:
- ceftolozane, an antibiotic that belongs to the group of “cephalosporins” and which can kill
certain bacteria that can cause infection;
- tazobactam, which blocks the action of certain enzymes called beta lactamases. These enzymes
make bacteria resistant to ceftolozane by breaking down the antibiotic before it can act. By
blocking their action, tazobactam makes ceftolozane more effective at killing bacteria.
Zerbaxa is used in adults to treat complicated infections within the abdomen, and kidney and urinary
system infections.
2. What you need to know before you take Zerbaxa
Do not take Zerbaxa
- if you are allergic to ceftolozane, tazobactam or any of the other ingredients of this medicine
(listed in section 6).
- if you are allergic to medicines known as “cephalosporins”.
- if you have had a severe allergic reaction (e.g., severe skin peeling; swelling of the face, hands,
feet, lips, tongue or throat; or difficulty swallowing or breathing) to certain other antibiotics
(e.g., penicillins or carbapenems).
Warnings and precautions
Talk to your doctor or pharmacist before taking Zerbaxa if you know you are, or have previously been
allergic to cephalosporins, penicillins or other antibiotics.
Talk to your doctor or pharmacist if you develop diarrhoea while taking Zerbaxa.
Infections caused by bacteria that are not sensitive to Zerbaxa or caused by a fungus can occur during
or following treatment with Zerbaxa. Tell your doctor if you think you may have another infection.
23
Treatment with Zerbaxa sometimes causes production of antibodies that react with your red blood
cells. If you are told that you have an abnormal blood test (called Coombs test) tell your doctor that
you are having or have recently had Zerbaxa.
Children and adolescents
This medicine should not be given to children under 18 years old because there is not enough
information on use in this age group.
Other medicines and Zerbaxa
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other
medicines.
Some medicines may interact with ceftolozane and tazobactam. These include:
- Probenecid (a medicine for gout). This can increase the time it takes for tazobactam to leave
your body.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, or think you may be pregnant, ask your doctor or pharmacist for
advice before taking this medicine. Your doctor will advise if you should receive Zerbaxa during
pregnancy.
If you are breast-feeding, your doctor will advise you on whether you should stop breast-feeding or
stop or avoid Zerbaxa therapy, taking into account the benefit of breast-feeding for the child and the
benefit of therapy for you.
Driving and using machines
Zerbaxa may cause dizziness, which can affect your ability to drive and use machines.
Zerbaxa contains sodium
This medicine contains 10.0 mmol (230 mg) of sodium per vial. The reconstituted vial with 10 mL of
0.9% sodium chloride (normal saline) for injection contains 11.5 mmol (265 mg) of sodium. This
should be taken into consideration if you are on a controlled-sodium diet.
3. How to take Zerbaxa
Your doctor or other healthcare professional will give you this medicine into one of your veins
through an infusion (a drip) lasting one hour. The dose of medicine given to you depends on whether
or not you have kidney problems.
Adults
The recommended dose is one vial of Zerbaxa (containing 1 g of ceftolozane and 0.5 g of tazobactam)
every 8 hours, which is given into one of your veins (directly into the bloodstream).
Treatment with Zerbaxa normally lasts between 4 and 14 days, depending on the severity and location
of the infection and on how your body responds to the treatment.
Patients with kidney problems
Your doctor may need to reduce the dose of Zerbaxa or decide how often Zerbaxa is given to you.
Your doctor may also want to test your blood to make sure you receive an appropriate dose, especially
if you have to take this medicine for a long time.
If you take more Zerbaxa than you should
As this product is given by a doctor or other healthcare professional, it is very unlikely that you will be
given too much Zerbaxa. However, if you have any concerns you should let your doctor, nurse or
pharmacist know immediately.
24
If you stop taking Zerbaxa
If you think you have not been given a dose of Zerbaxa, tell your doctor or other healthcare
professional immediately.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Other sources of information
Detailed information on this medicine is available on the European Medicines Agency web site:
http://www.ema.europa.eu.
---------------------------------------------------------------------------------------------------------------------------
The following information is intended for healthcare professionals only:
Preparation of solutions
Each vial is for single use only.
Aseptic technique must be followed in preparing the infusion solution.
Preparation of doses
The powder for concentrate for solution for infusion is reconstituted with 10 mL of water for
injections or sodium chloride 9 mg/mL (0.9%) solution for injection per vial; following reconstitution
the vial should be shaken gently to dissolve the powder. The final volume is approximately 11.4 mL.
The resultant concentration is approximately 132 mg/mL (88 mg/mL of ceftolozane and 44 mg/mL of
tazobactam).
CAUTION: THE RECONSTITUTED SOLUTION IS NOT FOR DIRECT INJECTION.
For preparation of the 1 g ceftolozane / 0.5 g tazobactam dose: Withdraw the entire contents
(approximately 11.4 mL) of the reconstituted vial using a syringe and add it to an infusion bag
containing 100 mL of 0.9% sodium chloride for injection (normal saline) or 5% glucose injection.
The preparations that follow relate to dose adjustments for renally impaired patients:
For preparation of the 500 mg ceftolozane / 250 mg tazobactam dose: Withdraw 5.7 mL of the
contents of the reconstituted vial and add it to an infusion bag containing 100 mL of 0.9% sodium
chloride for injection (normal saline) or 5% glucose injection.
For preparation of the 250 mg ceftolozane / 125 mg tazobactam dose: Withdraw 2.9 mL of the
contents of the reconstituted vial and add it to an infusion bag containing 100 mL of 0.9% sodium
chloride for injection (normal saline) or 5% glucose injection.
For preparation of the 100 mg ceftolozane / 50 mg tazobactam dose: Withdraw 1.2 mL of the contents
of the reconstituted vial and add it to an infusion bag containing 100 mL of 0.9% sodium chloride for
injection (normal saline) or 5% glucose injection.
Zerbaxa solution for infusion is clear and colourless to slightly yellow.
28
Variations in colour within this range do not affect the potency of the product.
After reconstitution, chemical and physical in-use stability has been demonstrated for 4 days at 2 to
8°C. The medicinal product is photosensitive and should be protected from light when not stored in
the original carton.
From a microbiological point of view, the medicinal product should be used immediately upon
reconstitution. If not used immediately, in-use storage times and conditions prior to use are the
responsibility of the user, unless reconstitution/dilution has taken place in controlled and validated
aseptic conditions and would normally not be longer than 24 hours at 2 to 8°C.
Any unused medicinal product or waste material should be disposed of in accordance
with local requirements.
