What is hydrocodone/acetaminophen, and what is it used for?
Hydrocodone is a narcotic pain-reliever and a cough suppressant, similar to codeine. Hydrocodone blocks the receptors on nerve cells in the brain that give rise to the sensation of pain.
Acetaminophen is a non-narcotic analgesic (pain reliever) and antipyretic (fever reducer). Acetaminophen works by elevating the threshold to pain, that is, in order for pain to be felt, greater stimulation of the nerves responsible for the sensation of pain is necessary. It reduces fever through its action on the temperature-regulating center of the brain.
- Frequently, hydrocodone and acetaminophen are combined to achieve pain relief, as in Vicodin and Lortab. The FDA approved Vicodin in January 1983.
Warnings
- Get emergency help right away if you take too much hydrocodone/acetaminophen (overdose). When you first start taking hydrocodone/acetaminophen, when your dose is changed, or if you take too much (overdose), serious or life-threatening breathing problems that can lead to death may occur.
- Taking hydrocodone/acetaminophen with other opioid medicines, benzodiazepines, alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, decreased awareness, breathing problems, coma, and death.
- Never give anyone else your hydrocodone/acetaminophen. They could die from taking it. Store hydrocodone/acetaminophen away from children and in a safe place to prevent stealing or abuse. Selling or giving away hydrocodone/acetaminophen is against the law.
Do not take hydrocodone/acetaminophen if you have:
- severe asthma, trouble breathing, or other lung problems.
- a bowel blockage or have narrowing of the stomach or intestines.
- known hypersensitivity to hydrocodone or acetaminophen, or any ingredient in hydrocodone/acetaminophen
What are the side effects of hydrocodone/acetaminophen?
Common side effects of hydrocodone/acetaminophen include:
- dizziness,
- drowsiness,
- tiredness,
- nausea,
- vomiting,
- stomach pain,
- constipation, and
- headache
Serious side effects of hydrocodone/acetaminophen include:
- hives,
- difficulty breathing,
- swelling of the face, lips, tongue, or throat,
- breathing that slows with a long pause,
- blue colored lips,
- difficult to wake up,
- skin redness or a rash that spreads and causes blistering and peeling,
- noisy breathing,
- sighing,
- shallow breathing that stops,
- lightheadedness,
- nausea,
- upper stomach pain,
- tiredness,
- loss of appetite,
- dark urine,
- clay-colored stools,
- yellowing of the skin or eyes,
- vomiting,
- loss of appetite,
- dizziness,
- worsening tiredness,
- weakness,
- agitation,
- hallucinations,
- fever,
- sweating,
- shivering,
- fast heart rate,
- muscle stiffness,
- twitching,
- loss of coordination,
- diarrhea, and
- spasm of the ureter, which can lead to difficulty in urinating.
Hydrocodone can impair thinking and the physical abilities required for driving or operating machinery. Hydrocodone can depress breathing and should be used with caution in elderly, debilitated patients and in patients with serious lung disease.
Hydrocodone may be habit-forming. Mental and physical dependence can occur but are unlikely when used for short-term pain relief.
Acetaminophen can cause severe liver failure if excessive amounts are used and when combined with chronic alcohol use or other drugs that also impair liver function.
This is not a complete list of all side effects or adverse reactions that may occur from the use of this drug. Call your doctor for medical advice about serious side effects or adverse reactions. You may also report side effects or health problems to the FDA at 1-800-FDA-1088.
SLIDESHOW
See SlideshowWhat are the dosages for hydrocodone/acetaminophen?
- The usual dose for adults is 1 to 2 tablets or capsules (hydrocodone 2.5 to 10 mg; acetaminophen 300 to 750 mg) every 4 to 6 hours, or
- 15 mL of liquid every 4 to 6 hours as needed.
Addiction/overdose
Hydrocodone
- Acute overdose with hydrocodone bitartrate and acetaminophen tablets can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations.
Acetaminophen
- Dose-dependent, potentially fatal hepatic necrosis is the most serious adverse effect of acetaminophen overdose. Renal tubular necrosis, hypoglycemic coma, and coagulation defects may also occur.
- Early symptoms following a potentially hepatotoxic overdose may include nausea, vomiting, diaphoresis, and general malaise. Clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours post-ingestion.
What drugs interact with hydrocodone/acetaminophen?
Inform your doctor of all medications you are currently taking, who can advise you on any possible drug interactions. Never begin taking, suddenly discontinue, or change the dosage of any medication without your doctor's recommendation.
- Patients receiving other narcotics, antihistamines, antipsychotics, antianxiety agents, or other CNS depressants (including alcohol) concomitantly with NORCO 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.
- Acetaminophen may produce false-positive test results for urinary 5-hydroxyindoleacetic acid.
