Congestion is a common problem in people all around the globe. Almost every second person in any country would be suffering from congestion at any time of the year. However, for most people, it is the winter months that bring in the need for nasal sprays and anti-congestion medications to be used. Where nasal congestion brings problems in ears, hearing and speech, it also is pretty much of an annoyance for a person. Nasal congestion keeps people irrigated, gives them problems in speaking and causes their attention to be diverted from other more important core issues.

With the start of the crucial seasons when one expects to get congestion or flu or anything of that sort, people begin taking anti-allergic medications, cough and flu syrups and other preventive medicines. One of the most commonly used medications at the time of nasal congestion is however a nasal spray. These sprays might vary in packing and sizes of the bottles depending on their brands and manufacturers but barely have any differences in terms of formulae of creation. The best choice to use would be a 12 hour nasal spray as it would help keep the nose from any kind of blockages and stuffiness for at least 12 hours. Even if the sprays actually do not work up for 12 hours, at least, many makers of nasal sprays claim to do so. And therefore, it can be safely said that the effect of these sprays would definitely be better than the ones whose effects are claimed to be short living by their manufacturers themselves. A number of pharmaceutical factories all around the globe are making nasal sprays but some of the best known brands are 4-Way Long Lasting, NRS-Nasal Relief, Genasal, Duration, Nostrilla, Afrin, Sinarest Nasal, Vicks Sinex 12 Hour, Nasin, Nasacon, Duramist Plus and Neo-Synephrine 12 Hour.            

These nasal sprays have been reported by many users to have worked effectively for up to 12 hours. However, before its use, a doctor must be concerned as use of any medication without a physician's advice and be fairly dangerous.
