WARNINGS May be habit forming. Hydrocodone can produce drug dependence of the morphine type and therefore, has the potential for being abused. Psychic dependence, physical dependence and tolerance may develop upon requested administration of this product and it should be used with the same degree of caution appropriate to the use of other narcotic drugs (see Drug, Abuse and Dependence section).
ADVERSE REACTIONS Adverse reactions include drowsiness, lassitude, nausea, giddiness, constipation, respiratory depression, addiction, blurred vision, cardiac palpitations, flushing, increased irritability or excitement. The most frequently observed adverse reactions include lightheadedness, dizziness, drowsiness, sedation, nausea and vomiting. These effects seem to be more predominate in ambulatory than in non-ambulatory patients, and some of these adverse reactions may be alleviated if the patient lies down. Respiratory System: Hydrocodone produces close-related respiratory depression by acting directly on the brain stem respiratory centers. Cardivascular: Hypertension, postural hypotension and palpitations. Genitourinary System: Ureleral spasm, spasm of vesicle sphincters and urinary retention have been reported with opiates. Central Nervous System : Sedation, drowsiness, mental clouding, lethargy, impairment of mental and physical performance, anxiety, fear, dysphoria, dizziness, psychic dependence, mood changes and blurred vision. Gastrointestinal System: Nausea and vomiting occur more frequently in ambulatory patients than in recumbent patients.
