Do you know the difference between adverse reaction,side effect and an allergy? Adverse reaction- Unexpected reaction to a substance, can often be life threatening. Examples: Respiratory failure after taking narcotics, muscle damage(Rhabdomyolysis) from statin drugs(Lipitor, Crestor, Zocor...) Side effect- A known reaction, good or bad to a substance. Examples: Drowsiness after taking an antihistamine, both good and bad. Diphenhydramine is a common sleep aid. Allergic reaction- This occurs after repeated exposures to a substance, the body becomes sensitized. Doesn't happen to everyone. The most serious form of allergic reaction is anaphylaxis, this requires immediate attention or person will die. Examples: Child takes amoxicillin on 3 different occasions, all is fine. Takes it a 4th time and develops hives, itching and a beautiful red rash. My own experience, I took Sulfa many times growing up, took again a few years ago and my tongue swelled up and I developed mouth ulcers. Another, a person gets a couple bee stings, no big deal. They get stung again and immediately the airway swells, they can't breathe, their whole body is failing. They need medical attention immediately and will need to carry an Epi-Pen for the rest of their life. Source(s): I'm a nurse it all sounds the same to me A true allergy, which you can find out with allergy tests, means that the worse case scenario is anaphalactic shock- your lungs closing up. HOWEVER, those tests do not tell you whether or not you are sensitive. You can break out in hives from something and have a negative reaction on a skin test. Many people show negative reactions to animals, but are in fact very sensitive to their hair and dander. An adverse reaction could be an allergy or it could just be sensitivity. A side effect is a possible reaction to a drug; it may or may not be an allergy. Adverse reactions are usually pretty serious. A side effect could be very mild or serious. |
