As any prescription and non prescription medication, Nexium can deliver certain effects outside those normally expected when used. Side effects rarely occur while taking Nexium as most people have good tolerance towards it, however there's still a minor risk of experiencing additional symptoms. In cases when Nexium side effects have occurred, they were reported to be minor and to wear off with time as the course of treatment continued. Still, if you notice anything strange and outside normal, you should inform your doctor while still taking Nexium on a regular basis. Only a doctor can tell if you should stop taking the drug.

Nexium was the subject of numerous clinical trial during which thousands of people have been observed all over the world. During these studies, one group of people was given Nexium, while another control group used placebo for comparing the results after trials. The results of the trials indicate that Nexium rarely develops any side effects, and if there are any symptoms, they are usually mild and temporary.

About one percent of the patients taking part in the trials reported the following side effects when using Nexium:

• Headache
• Diarrhea
• Nausea
• Flatulence
• Abdominal pain
• Constipation
• Dry mouth

There are other side effects as well. However, they have taken place in less than one percent of study participants and it's really hard to indicate whether these symptoms were actually caused by Nexium or had any other causes in these study participants. This expands the list of possible Nexium side effects to the following:

• Allergic reaction
• Back pain
• Chest pain
• Flushing
• High blood pressure
• Increased heart rate
• Indigestion
• Difficulty swallowing
• Earache
• Ringing of the ears
• Anemia
• Bloody nose
• Abnormal weight trends
• Fibromyalgia
• Acne
• Angioedema
• Skin rash
• Taste problems
• Intensification of depression
• Ear infection
• Blurred vision
• Pancreatitis
• Increased risk of bone fracture

It is quite normal to experience no side effects at all, and experience some of the mentioned above as well. Just make sure to inform your doctor about any odd symptoms that you may experience while taking Nexium. It is very important to describe the things you experience in details. Your doctor should know the intensity and frequency of the side effects in order to give you any indications. Even if it's not a side effect of this medication, it may be the sign of drug interaction with another medication that you may be taking. So it is also very important to tell your doctor if you are currently taking any prescription, non-prescription or recreational drugs.
