It's always nice to find out about a drug that not only helps you with a problem, but it cures you in many cases if the dosage and prescribed plan for you is followed correctly. Nexium is one of those medications that doctors prescribe regularly to their patients that have problems with heartburn, ulcers, and acid reflux. Called the "Purple Pill" Nexium fights GERD (Gastroesophageal Reflux Disease). Nexium works with the valve that stops stomach acid from going back up into the esophagus causing heartburn. Like all medications Nexium (esomeprazole magnesium) has some side effects that affect a small percentage of people that use it. These symptoms can include headache, diarrhea, and abdominal pain. High levels of stress can increase the symptoms of acid reflux disease and this is just one more reason to use Nexium. Today's lifestyle with the hustle and bustle of everyday life, fast foods, and always in hurry just makes things worse. Take control of this cycle in which might have caused this problem in the first place with Nexium, and get relief.
