Guide To The Side Effects Of Naproxen

Nausea And Vomiting

Nausea is not precisely a painful sensation but can be debilitating and very uncomfortable. Naproxen can cause nausea when it produces irritation in the tissues that line an individual's digestive tract. Mechanoreceptors and chemoreceptors send signals to the affected individual's brainstem when irritation is detected in the digestive lumen. The signals trigger several structures such as the dorsal motor vagus nucleus, central pattern generator, and solitary tract nucleus. These structures induce a chain of effects that accompany nausea in an affected individual, such as stopping the muscles of the lower digestive tract and increasing the production of saliva. Vomiting may occur following the feeling of nausea in an affected individual. Another circumstance where nausea and vomiting occur with naproxen use is when an ulcer has formed and has begun bleeding into the stomach.
