Dosage guidance:
Safety: Oxymetazoline should be administered with the patient and spray bottle in the upright position; administration to a patient in the supine position requires the spray bottle to be inverted resulting in significantly higher doses, increasing the risk of adverse effects and overdose (Ref).
Dosage form information: Nasal solution is available in 2 concentrations (0.025% solution and 0.05% solution); take precautions to verify product selection and avoid confusion between the different concentrations.
Nasal congestion: Note: Therapy should not exceed 3 days.
Children 2 to <6 years: 0.025% solution: Intranasal: Instill 2 to 3 sprays into each nostril twice daily as needed; doses should be separated by 10 to 12 hours; maximum daily dose: 2 doses/24 hours.
Children ≥6 years and Adolescents: 0.05% solution: Intranasal: Instill 2 to 3 sprays into each nostril twice daily; doses should be separated by 10 to 12 hours; maximum daily dose: 2 doses/24 hours.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no dosage adjustments provided in manufacturer's labeling.
There are no dosage adjustments provided in manufacturer's labeling.
(For additional information see "Oxymetazoline (nasal): Drug information")
Nasal congestion: Intranasal: Instill 2 to 3 sprays into each nostril twice daily (maximum dose: 2 doses/24 hours).
Duration: Generally limit to 3 to 5 days of consecutive use due to risk of rhinitis medicamentosa (Ref). In patients with persistent symptoms despite use of first-line therapies, some guidelines suggest oxymetazoline may be offered in combination with an intranasal corticosteroid for up to 4 weeks with low risk of rhinitis medicamentosa (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Postmarketing:
Cardiovascular: Acute coronary syndrome (Montastruc 2014), acute myocardial infarction (Rajpal 2014), angina pectoris (Shah 2018), cardiac arrhythmia (Shah 2018), hypertension (including hypertensive crisis) (Shah 2018, Loewen 2004), hypotension (Shah 2018), palpitations (Loewen 2004), syncope (Shah 2018)
Nervous system: Cerebrovascular accident (Cantu 2003), headache (including severe headache [thunderclap]) (Loewen 2004), subarachnoid hemorrhage (Cantu 2003)
OTC labeling: When used for self-medication, do not use for more than 3 days.
Concerns related to adverse effects:
• Local nasal effects: Temporary discomfort such as burning, stinging, sneezing, or an increased nasal discharge may occur.
• Rebound nasal congestion: Frequent or prolonged use may cause nasal congestion to recur or worsen.
Disease-related concerns:
• Cardiovascular disease: Use with caution in patients with hypertension or heart disease.
• Diabetes: Use with caution in patients with diabetes mellitus.
• Thyroid disease: Use with caution in patients with thyroid disease.
• Prostatic hyperplasia/urinary obstruction: Use with caution in patients with prostatic hyperplasia and/or GU obstruction.
Dosage form specific issues:
• Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer’s labeling.
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002; Lucente 2000; Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986; CDC 1984). See manufacturer’s labeling.
Other warnings/precautions:
• Accidental ingestion: Accidental ingestion by children of over-the-counter (OTC) imidazoline-derivative eye drops and nasal sprays may result in serious harm. Serious adverse reactions (eg, coma, bradycardia, respiratory depression, sedation) requiring hospitalization have been reported in children ≤5 years of age who had ingested even small amounts (eg, 1 to 2 mL). Contact a poison control center and seek emergency medical care immediately for accidental ingestion (FDA Drug Safety Communication 2012).
• Self-medication (OTC use): When used for self-medication (OTC), do not use >3 days; do not exceed recommended dosages; use of this container by more than one person may spread infection.
Some dosage forms may contain propylene glycol; in neonates large amounts of propylene glycol delivered orally, intravenously (eg, >3,000 mg/day), or topically have been associated with potentially fatal toxicities which can include metabolic acidosis, seizures, renal failure, and CNS depression; toxicities have also been reported in children and adults including hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP 1997; Shehab 2009).

Adverse fetal/neonatal events have been noted in case reports following large doses or extended use of oxymetazoline nasal spray in the first trimester of pregnancy (Baxi 1985; Holm 1985; Menezes 2016). Fetal blood flow was not found to be affected by a one-time dose of oxymetazoline in noncomplicated, third trimester pregnancies (Rayburn 1990).
Decongestants are not recommended for the treatment of rhinitis during pregnancy (BSACI [Scadding 2017]). Use of oxymetazoline nasal spray can be considered if acute relief is needed (Mazzotta 1999).
