While inhaling medicated oil can offer temporary relief for allergic rhinitis symptoms, it is not a long-term treatment and should be used with caution, according to medical experts. Its primary ingredients provide a sensation of clearer airways, but overuse can lead to adverse effects.
Medicated oil typically contains menthol, eucalyptus oil, camphor, and other ingredients that create a cool or warm sensation. When inhaled, these substances interact with cold sensory receptors (TRPM8) in the nasal lining. This interaction provides a feeling of clear airways, easier breathing, and reduced nasal congestion, offering immediate comfort.

However, medicated oil is not a treatment medication, and there are no formal recommendations for its dosage. In some cases, it can worsen symptoms such as increased sneezing, runny nose, and irritation of the eyes and nose. This is particularly true for individuals with asthma, young children, or those with sensitive nasal linings. Frequent use is also not recommended because menthol, camphor, and methyl salicylate can dry out the nasal lining, causing irritation, burning, and discomfort.
If you choose to use medicated oil, do so in moderation. Inhale a small amount through a tissue for temporary relief from discomfort due to weather-related nasal congestion or mild irritation. Adults should use it no more than two to three times a day, inhaling briefly each time. Do not place the oil directly against the nose; inhale for only a few seconds and do not hold it for too long.
Patients can also explore alternative methods for relief: adding two to three drops of essential oil to a bowl of hot water and inhaling the steam for 5-10 minutes, or using an essential oil diffuser to help thin mucus, soothe the nasal lining, and reduce congestion.
Allergic rhinitis is a condition where the nasal lining becomes irritated, leading to inflammation. It is not caused by viruses or bacteria but by environmental factors such as pollen, pet dander, dust, and dust mites. Common symptoms include nasal itching, sneezing, nasal congestion, runny nose, itchy eyes, red eyes, watery eyes, and loss of smell.
For comprehensive management of allergic rhinitis, patients should limit exposure to allergens, rinse their nose with physiological saline daily, and use a nasal irrigation device if there is excessive mucus. They should also take allergy medication as prescribed by a doctor. Boosting immunity, maintaining a balanced diet, getting adequate rest, and engaging in light exercise are also beneficial. If symptoms do not improve after 5-7 days, patients should consult an ear, nose, and throat doctor for timely examination and treatment to prevent complications such as acute or chronic sinusitis and nasal polyps.
