Side Effects of Drugs Vs Drug Allergy

One of the most probable mistakes that people do is to consider side effects of drugs to be allergies. There are a lot of similarities in both of the symptoms but both conditions are different. Dr. Sumeet explains the difference between these two, side effects of drugs can occur to anybody. For example 10 people taking a particular drug for flu will have the same side-effects on their body. Everyone taking that drug will have the same effect weather positive or negative. But in case of drug allergy, only the particular person who has a allergy to that drug will have a negative impact of that drug whereas other will have a positive one. 

Drug allergy can occur to one in a 100 people but side effects are same for everyone and can happen to anyone. Side-effects do not have any role to play in the immune response, whereas drug allergy is all about having a negative immune response on consuming that medicine.
