Why could it take 1-2 weeks before I notice the effect of Zicam Allergy Relief Nasal Gel?
Zicam Allergy Relief Nasal Gel begins working from the first time you use it. While it is not understood why consistent use over 1-2 weeks is necessary to see results, clinical research on this product indicate that it may take one to two weeks to see a decrease in symptoms. For best results, use Zicam Allergy Relief Nasal Gel up to one week before contact to known causes of your allergies.
