Can Afrin nasal spray be used as an aid to stop a nose bleed?

No, Afrin nasal spray and other over-the-counter remedies for nasal congestion should not be used to stop a nosebleed. In most cases, nosebleeds will stop on their own. Some home remedies like applying pressure, or saline solution can be used. If nosebleeds become a repeated event you should speak to your doctor who will be able to advise on potential courses of action to mitigate their recurrence.
