The management of serious infections due to organisms susceptible to this anti-infective.
Dalacin C Phosphate is contra-indicated in patients previously found to be sensitive to clindamycin,
lincomycin or to any components of the formulation particularly benzyl alcohol.
This product contains benzyl alcohol (9.45mg/ml as preservative). Intravenous administration of the
preservative benzyl alcohol has been associated with serious adverse events, and death in paediatric
patients including neonates characterized by central nervous system depression, metabolic acidosis,
gasping respirations, cardio-vascular failure and haematological anomalies (“gasping syndrome”).
Although normal therapeutic doses of this product ordinarily deliver amounts of benzyl alcohol that
are substantially lower than those reported in association with the “gasping syndrome”, the minimum
amount of benzyl alcohol at which toxicity may occur is not known. Use only if it is necessary and if
there are no alternatives possible. If given in high volumes, should be used with caution and
preferably for short term treatment in subjects with liver or kidney impairment because of the risk of
accumulation and toxicity (metabolic acidosis) due to benzoic acid (a metabolite of benzyl alcohol).
Premature and low-birth weight infants may be more likely to develop toxicity.
Benzyl Alcohol containing products should not be used in pre-term or full-term neonates unless
Benzyl alcohol can cross the placenta and clindamycin should only be used during pregnancy if
Dalacin C Phosphate should only be used in the treatment of serious infections. In considering the
use of the product, the practitioner should bear in mind the type of infection and the potential hazard
of the diarrhoea which may develop, since cases of colitis have been reported during, or even two or
three weeks following, the administration of clindamycin.
Studies indicate a toxin(s) produced by clostridia (especially Clostridium difﬁcile) is the principal direct

6. Further Information
1. What Dalacin C Solution is and
what it is used for
Dalacin C Solution is a sterile solution for injection into
a vein (intravenously) or into a muscle (intramuscularly).
The solution contains clindamycin phosphate which is
an antibiotic used in the treatment of serious bacterial
2. Before you are given Dalacin C
Do not use If you are allergic (hypersensitive) to
clindamycin, lincomycin or to any of the other
ingredients in this medicine.
Take special care with Dalacin C Solution
Before you are given this medicine make sure that your
doctor knows if you:
• have diarrhoea or usually get diarrhoea when you
take antibiotics or have ever suffered from problems
with your stomach or intestines (bowel disease). If
you develop severe or prolonged or bloody diarrhoea
during or after using Dalacin C Solution tell your
doctor immediately since it may be necessary to
interrupt the treatment. This may be a sign of bowel
inﬂammation (pseudomembranous colitis) which can
occur following treatment with antibiotics.
• you suffer from problems with your kidneys or liver.
• you suffer from asthma, eczema or hayfever. Dalacin
C does not get into the brain and is therefore not
suitable for treating serious infections in and around
the brain. Your doctor may need to give you another
antibiotic if you have these infections.
Taking other medicines
Some medicines can affect the way Dalacin C Solution
works, or Dalacin C itself can reduce the effectiveness
of other medicines taken at the same time. These
• erythromycin (an antibiotic).
• muscle relaxants used during operations
• oral contraceptive pills. You should use extra
contraception such as condoms whilst receiving
Dalacin C and for seven days after receiving Dalacin C.
• warfarin or similar medicines - used to thin the
blood. You may be more likely to have a bleed. Your
doctor may need to take regular blood tests to
check how well your blood can clot
Please tell your doctor if you are taking or have recently
taken any other medicines including medicines
obtained without a prescription.
If you are pregnant or think you might be pregnant you
should contact your doctor before being given
Dalacin C Solution.
Tell your doctor if you will be breast-feeding while you
are taking Dalacin C as the active substance in this
medicine may be passed into breast milk. Your doctor
will decide if Dalacin C is appropriate for you. Although
it is not likely that a nursing infant will take in very much
of the active substance from the milk it drinks, if your
baby gets bloodstained diarrhoea or shows any signs
of illness, tell your doctor at once. You should stop
breast-feeding if this happens.
Driving and using machines
No effects on the ability to drive or use machines have
been seen with Dalacin C Solution.
Important information about some of the
ingredients of Dalacin C Solution
Dalacin C Solution contains benzyl alcohol (9.45mg/ml
as preservative) and must not be given to premature
babies or babies less than one month old. It may cause
allergy and toxic reactions and has caused serious side
effects in the brain, heart, blood, and breathing rate in
children, which have been fatal in some cases.
3. How Dalacin C Solution is given
Your doctor will give you your medicine as an injection
into your vein (intravenous) or your muscle
(intramuscular). If it is given into a vein, it is always
cause of antibiotic-associated colitis. These studies also indicate that this toxigenic clostridium is
usually sensitive in-vitro to vancomycin. The disease is likely to follow a more severe course in older
patients, or patients who are debilitated.
Diagnosis is usually made by the recognition of the clinical symptoms, but can be substantiated by
endoscopic demonstration of pseudomembranous colitis. The presence of the disease may be
further conﬁrmed by culture of the stool for C. difﬁcile on selective media and assay of the stool
specimen for the toxin(s) of C. difﬁcile.
The appearance of marked diarrhoea should be regarded as an indication that the product should be
discontinued immediately. Clostridium difﬁcile associated diarrhoea (CDAD) has been reported to
occur over 2 months after the administration of antibacterial agents.
History of gastro-intestinal disease; use in atopic individuals; super-infection with resistant organisms.
Periodic liver and kidney function tests should be carried out during prolonged therapy. Such
monitoring is also recommended in neonates and infants. Safety and appropriate dosage in infants
less than one month old have not been established.
The dosage of Dalacin C Phosphate may require reduction in patients with renal or hepatic
impairment due to prolongation of the serum half-life.
Use with caution in patients receiving neuromuscular blocking agents. Do not use concurrently with
Vitamin K antagonists
Increased coagulation tests (PT/INR) and/or bleeding, have been reported in patients treated with
clindamycin in combination with a vitamin K antagonist (e.g. warfarin, acenocoumarol and ﬂuindione).
Coagulation tests, therefore, should be frequently monitored in patients treated with vitamin K
Pregnancy and lactation:
Safety of use in pregnancy has not been established. Exercise caution when prescribing to nursing
Benzyl alcohol can cross the placenta (see Warnings).
Side effects include nausea, vomiting, cramps, abdominal pain, diarrhoea, hypersensitivity reaction
such as Stevens Johnson syndrome, liver dysfunction and jaundice, blood dyscrasia, pruritus,
vaginitis, dermatitis, cardiopulmonary arrest and hypotension (following too rapid an administration)
and local reactions at the site of injection. The appearance of marked diarrhoea should be regarded
as an indication that this drug should be discontinued immediately.
In cases of overdosage no speciﬁc treatment is indicated. The serum biological half-life of lincomycin
is 2.4 hours. Clindamycin cannot readily be removed from the blood by dialysis or peritoneal dialysis.
If an allergic adverse reaction occurs, therapy should be with the usual emergency treatments,
including corticosteroids, adrenaline and antihistamines.
Handling and Storage requirements
Do not store this product above 25°C.
Do not refrigerate or freeze.

Dilution and Compatibility:
In-vitro compatibility studies monitored for 24 hours at room temperature using a concentration no
greater than 6 mg/ml have demonstrated no inactivation or physical incompatibility with the use of
Dalacin C Phosphate in IV solutions containing sodium chloride, glucose or potassium usually used
Dalacin C Phosphate has been shown to be physically and chemically compatible for at least
24 hours in dextrose 5% water and sodium chloride injection solutions containing the following
antibiotics in usually administered concentrations: amikacin sulphate, aztreonam, cefamondole
nafate, cephazolin sodium, cefotaxime sodium, cefoxitin sodium, ceftazidime sodium, ceftizoxime
sodium, gentamicin sulphate, netilmicin sulphate, piperacillin, tobramycin and ciproﬂoxacin.
The compatibility and duration of stability of drug admixtures will vary depending upon concentration
and other conditions.
Solutions of clindamycin salts have a low pH and incompatibilities may reasonably be expected with
alkaline preparations or drugs unstable at low pH. Incompatibility has been reported with: ampicillin
sodium, aminophylline, barbiturates, calcium gluconate, ceftriaxone sodium, diphenylhydantoin,
idarubicin hydrochloride, magnesium sulphate, phenytoin sodium and ranitidine hydrochloride.

When giving you Dalacin C, your doctor will ensure that
the concentration of clindamycin does not exceed 18
mg per ml and the rate it is given to you does not
exceed 30 mg per minute. If Dalacin is given too fast it
could rarely cause a heart attack.
The recommended dose of Dalacin C Solution is
600 to 2700 mg clindamycin per day in two to four equal
doses, depending on the severity of your infection. Higher
doses than this (up to 4800 mg daily) may be given by
your doctor for very severe infections.
The recommended dosage for children (over
1 month of age) is 15 to 40 mg of clindamycin per kg
bodyweight each day in three or four equal doses.
Higher doses of up to 300 mg per day (regardless of
body weight) may be given by your doctor for very
severe infections until a full response to treatment is
Normally Dalacin C is only given to patients in hospital.
The medical staff will be keeping a close eye on you
during your treatment. If you need to have more than
one course of treatment with clindamycin, your doctor
may want to check that the clindamycin is not having
any effect on the way your kidneys and liver are
Long term use can also make you more likely to get
other infections that do not respond to Dalacin C
If you have any further questions on the use of this
product, ask your doctor or pharmacist.
