Are menthol inhalers safe to use? Menthol inhalers are commonly used to relieve nasal congestion, especially during colds or allergic rhinitis. While they provide short-term relief by giving a cooling sensation and easing breathing, overuse can lead to side effects such as nasal dryness, irritation, or even dependence. In children, frequent or improper use should be avoided. Those with chronic sinus issues, asthma, or allergies should consult an ENT specialist before regular use. Dr. Jayabaskar,
