Why do all medications have side effects?

Answer 1

Medication is designed to cause chemical changes in your body. To think of what medicine really does to your body, look at it this way:

The drug enters your body. It causes molecules in your body to change or behave differently. Then all the molecules in your body that interact with those molecules will also be affected, and so on... drugs that affect the brain & mind cause people to experiece the most side effects, because the brain has the most influence on the rest of your body.

Also, different people have different side effects, because everyone's body chemistry is slightly different.

Answer 2

Because they are made from chemicals and have different reactions with different people depending on other medications they are taking, diet, and sensitivity to them. All chemicals act in more than one way and can't be refined to a specific action, although the drug companys try to reduce the extra action to reduce side effects to an acceptable level.

Answer 3

think of medicine as a guided missile and the body as a house, the missle is guided to certain characteristics of the house. Thus sometimes it may hit other targets causing side-effects, or else it may destroy one part of the house that causes other parts to be disturbed, aka: more cause side-effects. Because the body is so complex and so many reactions are intertwinned it is difficult to create medicine without some sideeffects.

Answer 4

It depends on the law of action as well. If there is an action ,the reaction( in medicine we call it side effect)is inevitable. Some reactions may be very little so that the patient may not experience it. Some may be very grave leading even to death immediately.

Answer 5

Any foreign substance one puts into their body will alter chemicals in the body. Humans weren't designed to have drugs in them whether you look at it from a religious standpoint or scientific standpoint. Our bodies want to maintain a state of balance like everything in the universe so anything that tries to disrupt that balance(medications) causes side effects.

Answer 6

because medications are made to alter the way your body works and sometimes the way your mind works. they either have good or bad side effects depending on how your body reacts to the medicine.

Answer 7

Because it's virtually impossible for there to be a med that ONLY attacks a virus or whatnot... they work by changing chemicals or other things in your body. And while that may help you feel better in the long run, the fact is that your body's chemistry gets altered, and sometimes that makes you feel differently.

Answer 8

All medications cause chemical reactions in your body (even food causes chemical reactions... like getting bloated after eating a lot). Chemical reactions don't just do one thing.

Answer 9

Medicines are designed to change the way your body reacts. That's what they do.

Answer 10

because of the different chemicals in them
