I never knew much about using Afrin for relief of nasal congestion until my husband told me about it when I was suffering from a cold. I was worried about getting sores inside my nose, as my nose was already hurting from blowing it so much. I bought this product and gave it a try. It was amazing and I could literally breath right after one spray. I love it. It helped open up the congestion in my sinuses and helped me to be able to breath and get some good rest. I never experienced any sores or discomfort in my nose from the spray and it did not drip at all, just as the box states. Congestion Relief I really only need one spray in each nostril to get me immediate relief. I only use it a few times a day when I am suffering from a cold or nasal congestion caused by allergies. It works quickly and effectively, without irritation to the nose. This is my go to product during allergy season. I keep a bottle in my purse at all times.
