Vilco Tonic Liquid is used for managing swollen nasal passages and providing quick relief from congestion. Oxymetazoline helps clear a stuffy nose caused by cold, allergies or sinusitis, making breathing easier and more comfortable. It helps provide relief for up to 10-12 hours with a single use, reducing the need for frequent dosing. The liquid helps reduce swelling in nasal tissues, allowing mucus to drain and relieving pressure in the sinuses. It may also help improve airflow through nasal passages, supporting restful sleep and easier breathing during the day or night. The key ingredient works locally in the nasal cavity with minimal systemic absorption, ensuring focused relief without drowsiness.
