Drug side effect is an effect that is secondary or unintended consequence of the drug administration in the body together with its intended purpose. The side effects of the drug can be either therapeutic or harmful to the body or a part of it. The drug side effects may vary from individual to individual and is dependent upon factors like age, gender, weight, disease, etc. The drug side effects can occur when starting or ending a drug medication regimen or while increasing or decreasing the dosage of it. In order to minimize the side effects of a drug, the current dosage may be adjusted or another medication can be prescribed. Also the lifestyle and or dietary changes may help to minimize the side effects of a drug. From a simple to the most sophisticated prescribed drug, all drugs come with side effects. The most common side effects for drug taken internally involve nausea or upset stomach, though it only happens to a handful of users. As compared to drugs applied externally skin irritation or allergy is commonly noticed. Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results. Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications. The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
