General
Special Risk PatientsAs with any narcotic analgesic agent, Lortab Elixir should be
used with caution in elderly or debilitated patients, and those with severe
impairment of hepatic or renal function, hypothyroidism, Addison’s disease,
prostatic hypertrophy or urethral stricture. The usual precautions should be
observed and the possibility of respiratory depression should be kept in
mind.
Cough ReflexHydrocodone suppresses the cough reflex; as with all narcotics,
caution should be exercised when Lortab Elixir are used postoperatively and in
patients with pulmonary disease.
Information for Patients
Hydrocodone, like all narcotics, may impair mental and/or
physical abilities required for the performance of potentially hazardous tasks
such as driving a car or operating machinery. Such tasks should be avoided while
taking this product.
Alcohol and other CNS depressants may produce an additive CNS depression,
when taken with this combination product, and should be avoided.
Hydrocodone may be habit-forming. Patients should take the drug only for as
long as it is prescribed, in the amounts prescribed, and no more frequently than
prescribed.
Physicians should instruct patients and caregivers to read the patient
information leaflet, which appears as the last section of the labeling.
Laboratory Tests
In patients with severe hepatic or renal disease, effects of
therapy should be monitored with serial liver and/or renal function tests.
Drug Interactions
Patients receiving narcotics, antihistamines, antipsychotics,
antianxiety agents, or other CNS depressants (including alcohol) concomitantly
with hydrocodone bitartrate and acetaminophen oral solution may exhibit an
additive CNS depression. When combined therapy is contemplated, the dose of one
or both agents should be reduced.
The use of MAO inhibitors or tricyclic antidepressants with hydrocodone
preparations may increase the effect of either the antidepressant or
hydrocodone.
Drug/Laboratory Test Interactions
Acetaminophen may produce false-positive test results for urinary
5-hydroxyindoleacetic acid.
Carcinogenesis, Mutagenesis, Impairment of
Fertility
No adequate studies have been conducted in animals to determine
whether hydrocodone has a potential for carcinogenesis, mutagenesis, or
impairment of fertility.
Hydrocodone has not demonstrated mutagenic potential using the Ames
Salmonella-Microsomal Activation test, the Basc test on Drosophila germ cells,
and the Micronucleus test on mouse bone marrow.

Pregnancy
Teratogenic EffectsPregnancy Category CThere are no adequate and well-controlled studies in pregnant
women. LORTAB Elixir should be used during pregnancy only if the potential
benefit justifies the potential risk to the fetus.
Nonteratogenic EffectsBabies born to mothers who have been taking opioids regularly
prior to delivery will be physically dependent. The withdrawal signs include
irritability and excessive crying, tremors, hyperactive reflexes, increased
respiratory rate, increased stools, sneezing yawning, vomiting and fever. These
signs usually appear during the first few days of life. The intensity of the
syndrome does not always correlate with the duration of maternal opioid use or
dose. There is no consensus on the best method of managing withdrawal.
Labor and Delivery
Narcotic analgesics cross the placental barrier. The closer to
delivery and the larger the dose used, the greater the possibility of
respiratory depression in the newborn. Narcotic analgesics should be avoided
during labor if delivery of a premature infant is anticipated. If the mother has
received narcotic analgesics during labor, newborn infants should be observed
closely for signs of respiratory depression. Resuscitation may be required ( see
OVERDOSAGE). The effect of hydrocodone, if any, on the
later growth, development, and functional maturation of the child is
unknown.
Nursing Mothers
Acetaminophen is excreted in breast milk in small amounts, but
the significance of its effects on nursing infants is not known. It is not known
whether hydrocodone is excreted in human milk. Because many drugs are excreted
in human milk and because of the potential for serious adverse reactions in
nursing infants from hydrocodone and acetaminophen, a decision should be made
whether to discontinue nursing or to discontinue the drug, taking into account
the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness in the pediatric population below the
age of two years have not been established. Use of LORTAB Elixir in the
pediatric population is supported by the evidence from adequate and well
controlled studies of hydrocodone and acetaminophen combination products in
adults with additional data which support the development of metabolic pathways
in children two years of age and over (see DOSAGE AND
ADMINISTRATION for pediatric dosage information).
Geriatric Use
Clinical studies of hydrocodone bitartrate and acetaminophen oral
solution did not include sufficient numbers of subjects aged 65 and over to
determine whether they respond differently from younger subjects. Other reported
clinical experience has not identified differences in responses between the
elderly and younger patients. In general, dose selection for an elderly patient
should be cautious, usually starting at the low end of the dosing range,
reflecting the greater frequency of decreased hepatic, renal, or cardiac
function, and of concomitant disease or other drug therapy.
Hydrocodone and the major metabolites of acetaminophen are known to be
substantially excreted by the kidney. Thus the risk of toxic reactions may be
greater in patients with impaired renal function due to the accumulation of the
parent compound and/or metabolites in the plasma. Because elderly patients are
more likely to have decreased renal function, care should be taken in dose
selection, and it may be useful to monitor renal function.
Hydrocodone may cause confusion and over-sedation in the elderly; elderly
patients generally should be started on low doses of hydrocodone bitartrate and
acetaminophen oral solution and observed closely.
