Concerns related to adverse effects:
- CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
- Phenanthrene hypersensitivity: Use with caution in patients with hypersensitivity reactions to other phenanthrene derivative opioid agonists (codeine, hydromorphone, levorphanol, morphine, oxycodone, oxymorphone).
- Respiratory depression: Hydrocodone may produce dose-related respiratory depression; use with caution; fatal respiratory depression has been reported with use and overdose of hydrocodone in children <6 years and adults, respectively.
Disease-related concerns:
- Abdominal conditions: May obscure diagnosis or clinical course of patients with acute abdominal conditions.
- Adrenal insufficiency: Use with caution in patients with adrenal insufficiency, including Addisons disease.
- Diabetes: Use with caution in patients with diabetes.
- Drug abuse: Use with caution in patients with a history of drug abuse or acute alcoholism; potential for drug dependency exists. Tolerance, psychological, and physical dependence may occur with prolonged use.
- Head trauma: Avoid use in patients with head injury, intracranial lesions, or elevated intracranial pressure (ICP); exaggerated elevation of ICP may occur.
- Hepatic impairment: Use with caution in patients with severe hepatic impairment.
- Prostatic hyperplasia/urinary obstruction: Use with caution in patients with prostatic hyperplasia and/or GU obstruction.
- Renal impairment: Use with caution in patients with severe renal impairment.
- Respiratory disease: Use with caution in patients with pulmonary disease or decreased ventilatory function; dose-related respiratory depression occurs.
- Seizure disorder: Use with caution in patients with a history of seizure disorder.
- Thyroid dysfunction: Use with caution in patients with thyroid dysfunction.
Concurrent drug therapy issues:
- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
Special populations:
- Debilitated patients: Use with caution in debilitated patients; there is a greater potential for critical respiratory depression, even at therapeutic dosages.
- Elderly: Use with caution in the elderly; may be more sensitive to adverse effects.
Other warnings/precautions:
- Administration: Use an accurate milliliter measuring device; a household teaspoon is not an accurate measuring device and could lead to overdosage, which can result in serious adverse reactions.
- Cough: Appropriate use: Underlying cause of cough should be determined prior to prescribing. Should not be used in patients with a persistent or chronic cough such as occurs with smoking, asthma, chronic bronchitis, or emphysema, or where cough is accompanied by excessive phlegm (mucus).
C
Animal reproduction studies have not been conducted with this combination. Refer to individual monographs.
Hydrocodone: Binds to opiate receptors in the CNS, altering the perception of and response to pain; suppresses cough in medullary center; produces generalized CNS depression
Guaifenesin: Irritates the gastric mucosa and stimulates respiratory tract secretions, thereby increasing respiratory fluid volumes and decreasing phlegm viscosity
- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience diarrhea, hot flash, or sweating a lot. Have patient report immediately to prescriber severe dizziness, passing out, angina, tachycardia, difficulty breathing, slow breathing, shallow breathing, confusion, arrhythmia, hallucinations, mood changes, seizures, severe abdominal pain, severe headache, difficult urination, tremors, vision changes, severe nausea, severe vomiting, severe constipation, severe loss of strength and energy, or severe fatigue (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
