Pharmaceutical Side Effects
Possible Drug and Prescription Side Effects

Pharmaceutical side effects are an unfortunate risk that exists when taking many common medicines and drugs. While there have been many advances and tremendous discoveries in recent years that help alleviate or prevent health problems, many of the drugs also have the risk for undesired side effects for some folks.

We are all familiar with the emotional, movie-level tv commercials for prescriptions for cholesterol drugs, sleep aid drugs and drugs for assisting in seniors love life. These commercials go over the top to touch on an emotional nerve, showing attractive people "just like you" that are enjoying life SO much more because they use the prescription being advertised. Then, we get the list of almost commical side effects at the very end of the commercial. Although these drugs do help many people and the side effects may sound funny, side effects are an important aspect for people to understand when taking any prescription medication.

Of course if you are a pharmacy technician, it will be helpful to have a familiarity with some of the side effects for common prescriptions so that you may have educated conversations with customers whom may ask questions. Obviously the most authoritative answer should come from a patients doctor but it will be helpful to be able to discuss the effects at a basic level.

Obviously while some of these symptoms are inconvenient, others are extremely serious and life-threatening. The pharmaceutical industry conducts tests and has to jump through many hoops to get new drugs to market for sale. But, ultimately, new medicines help many people and at some point decisions are made to allow them for sale to the public with the requirement of notifying folks of the possible side effects.

Hopefully this is a useful list of pharmaceutical side effects
