How do you make your nose stop running?

To stop a runny nose, you can try using over-the-counter antihistamines, which help reduce allergy symptoms, or decongestants that relieve nasal congestion. Staying hydrated and using a saline nasal spray can also help thin mucus and ease drainage. Additionally, applying a warm compress to your face may provide relief. If symptoms persist, consult a healthcare professional for further advice.
