May occur with intranasal administration. Typically resolves with continued use as nasal mucosa adapts. Can be minimized by allowing solution to reach room temperature and using gentle administration technique.

May occur shortly after administration, particularly with initial doses. Usually transient and resolves within 30-60 minutes. Ensure adequate hydration.

Localized inflammatory response to intranasal administration. Consider pre-treatment with saline rinse if persistent. Discontinue if severe.

May occur if solution drains posteriorly to the oropharynx. Typically mild and transient. Rinse mouth with water if bothersome.

Rare with proper intranasal technique. More likely if nasal mucosa is already compromised or if administration is too forceful. Apply gentle pressure and discontinue if bleeding persists.

Anaphylaxis or severe allergic response is extremely rare but possible. Seek immediate medical attention if experiencing difficulty breathing, throat swelling, or severe rash.
