Diazepam (Injection, Solution)
|
dailymed-instance:dosage |
Dosage should be individualized for maximum beneficial
effect. The usual recommended dose in older children and adults ranges
from 2 mg to 20 mg IM or IV, depending on the indication and its severity.
In some conditions, e.g., tetanus, larger doses may be required. (See
dosage for specific indications.) In acute conditions the injection
may be repeated within one hour although an interval of 3 to 4 hours
is usually satisfactory. Lower doses (usually 2 mg to 5 mg) and slow
increase in dosage should be used for elderly or debilitated patients
and when other sedative drugs are administered. (See WARNINGS and ADVERSE REACTIONS.) For dosage in infants above the age of 30 days and children,
see the specific indications below. When intravenous use is indicated,
facilities for respiratory assistance should be readily available. Intramuscular: Diazepam injection should be injected deeply into the muscle. Intravenous Use: (See WARNINGS, particularly
for use in children.) The solution should be injected slowly, taking
at least one minute for each 5 mg (1 mL) given. Do not use small veins,
such as those on the dorsum of the hand or wrist. Extreme care should
be taken to avoid intra-arterial administration or extravasation. Do not mix or dilute diazepam with other solutions or
drugs in syringe or infusion flask. If it is not feasible to administer
diazepam directly IV, it may be injected slowly through the infusion
tubing as close as possible to the vein insertion. Once the acute symptomatology has been properly controlled with diazepam
injection, the patient may be placed on oral therapy with diazepam
if further treatment is required. Parenteral drug products should be inspected visually
for particulate matter and discoloration prior to administration,
whenever solution and container permit.

dailymed-instance:descripti... |
Each mL of this sterile injection contains 5 mg diazepam
compounded with 40% propylene glycol, 10% alcohol, 5% sodium benzoate
and benzoic acid as buffers, and 1.5% benzyl alcohol as preservative. Diazepam is a benzodiazepine derivative. Chemically, diazepam
is 7-chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one.
It is a colorless crystalline compound, insoluble in water and has
a molecular weight of 284.74. The solution is clear, colorless to
slightly yellow.

In animals, diazepam appears to act on parts of the
limbic system, the thalamus and hypothalamus, and induces calming
effects. Diazepam, unlike chlorpromazine and reserpine, has no demonstrable
peripheral autonomic blocking action, nor does it produce extrapyramidal
side effects; however, animals treated with diazepam do have a transient
ataxia at higher doses. Diazepam was found to have transient cardiovascular
depressor effects in dogs. Long-term experiments in rats revealed
no disturbances of endocrine function. Injections into animals have
produced localized irritation of tissue surrounding injection sites
and some thickening of veins after intravenous use.

Although seizures may be brought under control promptly,
a significant proportion of patients experience a return to seizure
activity, presumably due to the short-lived effect of diazepam after
IV administration. The physician should be prepared to readminister
the drug. However, diazepam is not recommended for maintenance, and
once seizures are brought under control, consideration should be given
to the administration of agents useful in longer term control of seizures. If diazepam is to be combined with other psychotropic
agents or anticonvulsant drugs, careful consideration should be given
to the pharmacology of the agents to be employed, particularly with
known compounds which may potentiate the action of diazepam, such
as phenothiazines, narcotics, barbiturates, MAO inhibitors, and other
antidepressants. In highly anxious patients with evidence of accompanying
depression, particularly those who may have suicidal tendencies, protective
measures may be necessary. The usual precautions in treating patients
with impaired hepatic function should be observed. Metabolites of
diazepam are excreted by the kidney; to avoid their excess accumulation,
caution should be exercised in the administration to patients with
compromised kidney function. Since an increase
in cough reflex and laryngospasm may occur with peroral endoscopic
procedures, the use of a topical anesthetic agent, and the availability
of necessary countermeasures are recommended. Until additional information is available, diazepam injection is
not recommended for obstetrical use. Diazepam
injection has produced hypotension or muscular weakness in some patients
particularly when used with narcotics, barbiturates, or alcohol. Lower doses (usually 2 mg to 5 mg) should be used for
elderly and debilitated patients. The clearance
of diazepam and certain other benzodiazepines can be delayed in association
with Tagamet (cimetidine) administration. The clinical
significance of this is unclear.
|
dailymed-instance:overdosag... |
Manifestations of diazepam
overdosage include somnolence, confusion, coma, and diminished reflexes.
Respiration, pulse, and blood pressure should be monitored, as in
all cases of drug overdosage, although, in general, these effects
have been minimal. General supportive measures should be employed,
along with intravenous fluids, and an adequate airway maintained.
Hypotension may be combated by the use of Levophed (norepinephrine bitartrate) or Aramine (metaraminol). Dialysis is
of a limited value. Flumazenil, a
specific benzodiazepine receptor antagonist, is indicated for the
complete or partial reversal of the sedative effects of benzodiazepines
and may be used in situations when an overdose with a benzodiazepine
is known or suspected. Prior to the administration of flumazenil,
necessary measures should be instituted to secure airway, ventilation,
and intravenous access. Flumazenilis intended as an adjunct to, not
as a substitute for, proper management of benzodiazepine overdose.
Patients treated with flumazenil should be monitored for resedation,
respiratory depression, and other residual benzodiazepine effects
for an appropriate period after treatment. The prescriber should be aware of a risk of seizure in association
with flumazenil treatment, particularly in long-term benzodiazepine
users and cyclic antidepressant overdose. The complete
flumazenil package insert including CONTRAINDICATIONS, WARNINGS, and PRECAUTIONS should
be consulted prior to use.

Side effects most commonly reported were drowsiness,
fatigue, and ataxia; venous thrombosis and phlebitis at the site of
injection. Other adverse reactions less frequently reported include: Central Nervous System: Confusion, depression, dysarthria, headache, hypoactivity, slurred
speech, syncope, tremor, vertigo. Gastrointestinal: Constipation, nausea. Genitourinary: Incontinence,
changes in libido, urinary retention. Cardiovascular: Bradycardia, cardiovascular
collapse, hypotension. EENT: Blurred vision, diplopia, nystagmus. Skin: Urticaria, skin rash. Other: Hiccups,
changes in salivation, neutropenia, jaundice. Paradoxical reactions
such as acute hyperexcited states, anxiety, hallucinations, increased
muscle spasticity, insomnia, rage, sleep disturbances and stimulation
have been reported; should these occur, use of the drug should be
discontinued. Minor changes in EEG patterns, usually low-voltage fast
activity, have been observed in patients during and after diazepam
therapy and are of no known significance. In
peroral endoscopic procedures, coughing, depressed respiration, dyspnea,
hyperventilation, laryngospasm, and pain in throat or chest have been
reported. Because of isolated reports of neutropenia
and jaundice, periodic blood counts and liver function tests are advisable
during long-term therapy.

dailymed-instance:warning |
When used intravenously,
the following procedures should be undertaken to reduce the possibility
of venous thrombosis, phlebitis, local irritation, swelling, and,
rarely, vascular impairment; the solution should be injected slowly,
taking at least one minute for each 5 mg (1 mL) given; do not use
small veins, such as those on the dorsum of the hand or wrist; extreme
care should be taken to avoid intra-arterial administration or extravasation. Do not mix or
dilute diazepam injection with other solutions or drugs in syringe
or infusion flask. If it is not feasible to administer diazepam directly
IV, it may be injected slowly through the infusion tubing as close
as possible to the vein insertion. Extreme care must be used in administering diazepam injection, particularly
by the IV route, to the elderly, to very ill patients, and to those
with limited pulmonary reserve because of the possibility that apnea
and/or cardiac arrest may occur. Concomitant use of barbiturates,
alcohol or other central nervous system depressants increases depression
with increased risk of apnea. Resuscitative equipment including that
necessary to support respiration should be readily available. When diazepam is used with a narcotic analgesic, the dosage
of the narcotic should be reduced by at least one-third and administered
in small increments. In some cases the use of a narcotic may not be
necessary. Diazepam injection should not be
administered to patients in shock, coma, or in acute alcoholic intoxication
with depression of vital signs. As is true of most CNS-acting drugs,
patients receiving diazepam should be cautioned against engaging in
hazardous occupations requiring complete mental alertness, such as
operating machinery or driving a motor vehicle. Tonic status epilepticus has been precipitated in patients treated
with IV diazepam for petit mal status or petit mal variant status. Usage in Pregnancy: An increased risk of congenital malformations
associated with the use of minor tranquilizers (diazepam, meprobamate,
and chlordiazepoxide) during the first trimester of pregnancy has
been suggested in several studies. Because use of these drugs is rarely
a matter of urgency, their use during this period should almost always
be avoided. The possibility that a woman of childbearing potential
may be pregnant at the time of institution of therapy should be considered.
Patients should be advised that if they become pregnant during therapy
or intend to become pregnant they should communicate with their physicians
about the desirability of discontinuing the drug. In humans, measurable amounts of diazepam were found in
maternal and cord blood, indicating placental transfer of the drug.
Until additional information is available, diazepam injection is not
recommended for obstetrical use. Use in Children: Efficacy and safety
of parenteral diazepam has not been established in the neonate (30
days or less of age). Prolonged central nervous
system depression has been observed in neonates, apparently due to
inability to biotransform diazepam into inactive metabolites. In pediatric use, in order to obtain maximal clinical
effect with the minimum amount of drug and thus to reduce the risk
of hazardous side effects, such as apnea or prolonged periods of somnolence,
it is recommended that the drug be given slowly over a three-minute
period in a dosage not to exceed 0.25 mg/kg. After an interval of
15 to 30 minutes the initial dosage can be safely repeated. If, however,
relief of symptoms is not obtained after a third administration, adjunctive
therapy appropriate to the condition being treated is recommended. Withdrawal symptoms of the barbiturate type have occurred
after the discontinuation of benzodiazepines (see DRUG ABUSE AND DEPENDENCE section).

dailymed-instance:indicatio... |
Diazepam is indicated for the management of anxiety
disorders or for the short-term relief of the symptoms of anxiety.
Anxiety or tension associated with the stress of everyday life usually
does not require treatment with an anxiolytic. In acute alcohol withdrawal, diazepam may be useful in the symptomatic
relief of acute agitation, tremor, impending or acute delirium tremens
and hallucinosis. As an adjunct prior to endoscopic
procedures if apprehension, anxiety or acute stress reactions are
present, and to diminish the patient's recall of the procedures.
(See WARNINGS.) Diazepam is a useful adjunct for the relief of skeletal
muscle spasm due to reflex spasm to local pathology (such as inflammation
of the muscles or joints, or secondary to trauma); spasticity caused
by upper motor neuron disorders (such as cerebral palsy and paraplegia);
athetosis; stiff-man syndrome; and tetanus. Diazepam injection is a useful adjunct in status epilepticus and
severe recurrent convulsive seizures. Diazepam
is a useful premedication (the IM route is preferred) for relief of
anxiety and tension in patients who are to undergo surgical procedures.
Intravenously, prior to cardioversion for the relief of anxiety and
tension and to diminish the patient's recall of the procedure.
