Otrivin Allergy (Dimetindene Maleate, Phenylephrine)

Dimetindene maleate blocks H1 histamine receptors in the nasal mucosa, preventing histamine from binding and triggering the cascade that leads to itching, swelling, and increased secretions. By antagonizing these receptors, it reduces the allergic response and associated nasal symptoms.

The exact dose and frequency are determined by the prescribing healthcare professional based on the patient’s age, severity of symptoms and local labeling. Typically, the product is administered as a few sprays into each nostril, but the prescriber sets the specific regimen.

Safety data for dimetindene maleate and phenylephrine during pregnancy and lactation are limited. Women who are pregnant, planning pregnancy, or breastfeeding should consult their physician before using Otrivin Allergy to weigh potential benefits against any possible risks.

Compared with single‑ingredient antihistamine sprays, Otrivin Allergy adds phenylephrine, providing both antihistamine relief and immediate decongestion. This dual action can be more effective for patients with prominent nasal blockage, whereas pure antihistamine sprays mainly address itching and sneezing.

Otrivin Allergy should be stored at room temperature, below 25 °C, in its original container. Keep the bottle tightly closed, protect it from moisture and direct sunlight, and keep it out of reach of children.

The spray is used intranasally. After gently shaking the bottle, the user inserts the tip into one nostril, closes the opposite nostril, and presses the actuator to deliver the recommended number of sprays. The process is then repeated in the other nostril if directed by the prescriber.

Although uncommon, serious adverse reactions can include severe allergic responses such as anaphylaxis, significant hypertension, arrhythmias, or nasal ulceration. Any signs of difficulty breathing, rapid heartbeat, severe nosebleeds, or swelling of the face or throat require immediate medical attention.

Individuals with known hypersensitivity to dimetindene, phenylephrine or any excipients in the formulation should avoid the product. It is also contraindicated in patients taking monoamine oxidase inhibitors, other nasal decongestants, or those with uncontrolled high blood pressure unless advised by a physician.
