Always follow your doctor’s instructions precisely. Using more spray than prescribed won’t speed up relief and could cause harm.
Potential Side Effects
Common side effects include a temporary burning or stinging sensation in your nose. Less frequent, but possible, are drowsiness, dizziness, and numbness in the mouth. Report any unusual symptoms to your healthcare provider immediately.
Precautions
Avoid driving or operating machinery after using the spray until you know how it affects you. Alcohol can intensify lidocaine’s effects. Inform your doctor about all medications you’re taking, including over-the-counter drugs and supplements, to avoid potential drug interactions. If you have a history of heart problems, liver disease, or kidney disease, discuss the use of lidocaine nasal spray with your physician before using it. Pregnant or breastfeeding women should also consult their doctors before using this medication.
Allergic Reactions
While rare, allergic reactions can occur. Watch for symptoms like rash, hives, swelling, or difficulty breathing. Seek immediate medical attention if you experience an allergic reaction.
Long-term Use
Prolonged use of lidocaine nasal spray can lead to decreased effectiveness and potential tolerance. Do not exceed the prescribed dosage or duration of treatment. Contact your doctor if your symptoms persist or worsen after using the spray as directed.
