🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, reducing sneezing, itching, runny nose, and vascular permeability. Phenylephrine is an alpha-1 adrenergic agonist that constricts nasal blood vessels, decreasing mucosal swelling and congestion. Together they provide symptomatic relief of allergic and cold-related nasal symptoms.
Mechanism Steps
💡 How to Take monkuff oral drops
Strength: This medicine is an oral syrup containing chlorpheniramine maleate 2 mg/mL and phenylephrine 2.5 mg/mL. The strength may also be expressed as chlorpheniramine maleate 2 mg and phenylephrine 2.5 mg per dose volume as specified on the label.
Dosage Information
| Adult Dosage | The adult dose of this medicine is usually 5 to 10 mL taken orally every 4 to 6 hours as needed for symptom relief, but the exact dose and frequency must be individualized by a qualified clinician based on the indication, age, weight, renal and hepatic function, and response to treatment. Do not exceed the maximum daily dose recommended by your doctor. This medicine is intended for short-term use only. |
| Pediatric Dosage | Pediatric dosing of this medicine is not established from available information. Consult a pediatrician for appropriate dosing in children, as it depends on age, weight, and clinical condition. Do not give this medicine to children under 2 years of age unless specifically prescribed by a doctor. |
| Elderly Dosage | Older adults are more sensitive to the sedative and anticholinergic effects of chlorpheniramine maleate and the cardiovascular effects of phenylephrine. The dose should be individualized by a clinician, and lower doses may be appropriate. Use with caution in patients above 65 years of age, and monitor for confusion, urinary retention, and falls. |
| Renal Impairment | Dose adjustment may be needed in patients with severe renal impairment because chlorpheniramine maleate and phenylephrine are excreted by the kidneys. Consult a doctor or pharmacist for individualized dosing. Not established from the available information for specific renal dose adjustments. |
| Hepatic Impairment | Dose adjustment may be needed in patients with severe hepatic impairment because chlorpheniramine maleate is metabolized in the liver and phenylephrine undergoes first-pass metabolism. Consult a doctor for individualized dosing. Not established from the available information for specific hepatic dose adjustments. |
| Maximum Daily Dose | The maximum daily dose of this medicine depends on the prescribed strength and frequency. Do not exceed the dose recommended by your doctor. For adults, the usual maximum is 10 mL every 4 to 6 hours, not to exceed 60 mL in 24 hours, but this must be confirmed by a qualified clinician. Do not self-medicate beyond the recommended duration. |
