Side Effects
Side effects (/saɪd ɪˈfɛkts/), also known as adverse effects, are unintended consequences that can occur with the use of medical treatment or medication. They can range from mild to severe and can occur immediately or develop over time.
Etymology
The term "side effect" originates from the mid-20th century, derived from the concept of an effect being secondary or "to the side" of the intended effect. The term "adverse effect" is often used interchangeably, emphasizing the negative impact of the effect.

Understanding Side Effects
Side effects can occur for a variety of reasons. They may be a direct result of the pharmacological action of a drug, or they may be caused by the body's reaction to the drug. Some side effects are common and expected, while others are rare and unexpected. Side effects can also vary greatly between individuals, with some people experiencing no side effects at all, while others may experience severe side effects.
Side effects can be temporary or long-lasting, and they can occur immediately after taking a drug or only after long-term use. Some side effects can be managed with supportive care, while others may require discontinuation of the drug.
Reporting Side Effects
In many countries, healthcare professionals and patients are encouraged to report any suspected side effects to their national pharmacovigilance system. This helps to ensure that all potential side effects are identified and managed appropriately.
