Otrivin Advance is available as a nasal spray, which is a liquid form delivered as a fine mist into the nasal passages. It is not available as a gas. This liquid spray helps relieve nasal congestion effectively by shrinking swollen blood vessels in the nose. If you have any more questions about its use or forms, feel free to ask!

For personalized advice or if you have concerns about nasal congestion, consulting an ear, nose, and throat (ENT) specialist would be beneficial.
