I had a wonderful experience with this nasal spray from CVS. I am a teacher and am outside every day due to recess duty. My allergies are constantly causing my nose to run or be stopped up. I found this nasal spray one day after work. It worked wonders for me within the first thirty minutes of using it. It completely cleared up my nose congestion and kept it from running. I carry it with me in my purse now so that I can use it whenever I need it. You can only do about two sprays every 8 or so hours. However, it is powerful enough to last that long. It is one of the best nasal sprays I have tried out. I would highly recommend this product to anyone dealing with nose congestion or a runny nose. The price is a little steep but you are paying for quality. It also lasts a long time. Effectiveness It is highly effective at clearing up any nose congestion problems. It also treats a runny nose. Ease of Use It is very easy to use. Immediacy I got results within thirty minutes of using this.
