Temporary relief of upper respiratory symptoms associated with allergy or the common cold
Hypersensitivity to promethazine, phenylephrine, or any component of the formulation (cross-reactivity between phenothiazines may occur;) treatment of lower respiratory tract symptoms, including asthma; hypertension; ventricular tachycardia; peripheral vascular insufficiency; use with or within 14 days of MAO inhibitor therapy
Promethazine hydrochloride should not be used in pediatric patients less than 2 years of age because of the potential for fatal respiratory depression. Postmarketing cases of respiratory depression, including fatalities, have been reported with use of promethazine hydrochloride in pediatric patients less than 2 years of age. A wide range of weight-based doses of promethazine hydrochloride have resulted in respiratory depression in these patients.
Caution should be exercised when administering promethazine hydrochloride to pediatric patients 2 years of age and older. It is recommended that the lowest effective dose of promethazine hydrochloride be used in pediatric patients 2 years of age and older and concomitant administration of other drugs with respiratory depressant effects be avoided.

See individual agents.
Concerns related to adverse effects:
- Altered cardiac conduction: May alter cardiac conduction (life-threatening arrhythmias have occurred with therapeutic doses of phenothiazines).
- Anticholinergic effects: Phenothiazines may cause anticholinergic effects (constipation, xerostomia, blurred vision, urinary retention); therefore, they should be used with caution in patients with decreased gastrointestinal motility, urinary retention, BPH, xerostomia, or visual problems.
- Extrapyramidal symptoms: May cause extrapyramidal symptoms, including pseudoparkinsonism, acute dystonic reactions, akathisia, and tardive dyskinesia.
- Neuroleptic malignant syndrome (NMS): Use may be associated with NMS; monitor for mental status changes, fever, muscle rigidity and/or autonomic instability.
- Orthostatic hypotension: May cause orthostatic hypotension; use with caution in patients at risk of this effect or in those who would not tolerate transient hypotensive episodes (cerebrovascular disease, cardiovascular disease, hypovolemia, or concurrent medication use which may predispose to hypotension/bradycardia).
- Sedation: May be sedating, use with caution in disorders where CNS depression is a feature; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
- Temperature regulation: Impaired core body temperature regulation may occur; caution with strenuous exercise, heat exposure, dehydration, and concomitant medication possessing anticholinergic effects.
Disease-related concerns:
- Bone marrow suppression: Use with caution in patients with bone marrow suppression; leukopenia and agranulocytosis have been reported.
- Cardiovascular disease: Use with caution in patients with severe cardiovascular disease.
- Diabetes: Use phenylephrine with caution in patients with diabetes mellitus.
- Glaucoma: Use with caution in patients with narrow-angle glaucoma and/or increased intraocular pressure; condition may be exacerbated by cholinergic blockade. Screening is recommended.
- Hepatic impairment: Use with caution in patients with hepatic impairment; cholestatic jaundice has been reported with use. Avoid use in pediatric patients with signs and symptoms of hepatic disease (extrapyramidal symptoms caused by promethazine may be confused with CNS signs of hepatic disease).
- Hyperthyroidism: Use phenylephrine with caution in patients with hyperthyroidism.
- Myasthenia gravis: Use with caution in patients with myasthenia gravis; condition may be exacerbated by cholinergic blockade.
- Parkinson disease: Use with caution in patients with Parkinson disease; may have increased risk of tardive dyskinesia.
- Prostatic hyperplasia: Use phenylephrine with caution in patients with prostatic hyperplasia.
- Respiratory disease: Use with caution in patients with severe respiratory disease (asthma, COPD, sleep apnea); may lead to potentially fatal respiratory depression.
- Seizures: Use with caution in patients at risk of seizures, including those with a history of seizures, head trauma, brain damage, alcoholism, or concurrent therapy with medications which may lower seizure threshold.
Concurrent drug therapy issues:
- Antiemetic effects: May mask toxicity of other drugs or conditions (eg, intestinal obstruction, Reyes syndrome, brain tumor) due to antiemetic effects.
- Sedatives: Effects may be potentiated when used with other sedative drugs or ethanol.
Special populations:
- Elderly: Use phenylephrine with caution in the elderly.
- Pediatric: [U.S. Boxed Warning]: Safety and efficacy of this combination have not been established in children <2 years of age (use of promethazine is contraindicated). In children ≥2 years, use the lowest possible dose; other drugs with respiratory depressant effects should be avoided. Avoid use in children who may have Reye syndrome or hepatic disease as adverse reactions caused by promethazine may be confused with signs of primary disease.
C
Reproduction studies have not been conducted with this combination. Refer to individual monographs.
- 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 fatigue, dizziness, anxiety, dry mouth, or insomnia. Have patient report immediately to prescriber signs of infection, difficulty breathing, slow breathing, shallow breathing, loss of strength and energy, hallucinations, mood changes, tinnitus, seizures, bruising, bleeding, urinary retention, change in amount of urine passed, abnormal movements, twitching, change in balance, dysphagia, difficulty speaking, jaundice, or signs of neuroleptic malignant syndrome (fever, muscle cramps or stiffness, dizziness, very bad headache, confusion, change in thinking, fast heartbeat, abnormal heartbeat, or sweating a lot) (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.
